1. Introduction
Project Overview
TNG Limited (TNG) (the Proponent), proposes to construct and operate the Darwin Processing Facility (the Project) at Wickham in the Northern Territory (NT). The Project is proposed to process magnetite concentrate (concentrate hereafter) to produce:
Vanadium pentoxide (V2O5) flake– for use in steel, non-ferrous alloys, chemicals, catalysts and energy storage (vanadium redox batteries);
Titanium dioxide – for use in paint, plastics, paper and inks; and Ferric oxide – for use in steel making.
The three products will be exported through the Port of Darwin’s East Arm Wharf (EAW) to international customers.
The Processing Facility is proposed to be located on Lot 1817, Hundred of Ayers, Middle Arm Industrial Precinct, Wickham, approximately 16 km south east of Darwin, in the NT (Figure 1). The site is located adjacent to the Elizabeth River and encompasses 507 hectares (ha), of which 40 ha is mangrove forest and intertidal zone, and 467 ha is terrestrial land. The Project and associated access roads, supporting infrastructure and service comprise a development footprint of approximately 264 ha.
The magnetite concentrate will be produced at TNG’s proposed Mount Peake Project approximately 1,400 km south of Darwin, which is the subject of a separate environmental assessment and approvals process. The Mount Peake Project will involve the mining of a polymetallic ore body (enriched with vanadium, titanium and iron) and beneficiation of the ore to produce magnetite concentrate. The concentrate will be transported by rail from the mine site to the Processing Facility.
An ocean outfall is required as part of the Project operation to dispose of waste by-products. The ocean outfall is proposed to discharge approximately 12 GL/year of treated process water into the Elizabeth River.

Environmental Approvals
TNG submitted a notice of Intent (NOI) to the Northern Territory Environment Protection Authority (NT EPA) and Department of Lands Planning and Environment (DLPE) on 27 October 2015 for consideration under the Environment Assessment Act 1982 (EA Act).
On 15 January 2016, the NT EPA determined the Project requires assessment at the level of an Environmental Impact Statement (EIS). The NT EPA decision was based on the following risks and potential environmental impacts:
Risks to biodiversity values1 of adjacent areas, including nationally significant mangrove communities2, marine ecosystems, local fisheries and listed threatened species;
Environmental risks associated with vegetation clearing, erosion and sediment control, uncontrolled discharges, dust, spills, disturbance of acid sulfate soils, contamination of soils, surface water and / or ground water;
Potential for Project noise, lighting and emissions to impact on existing residents, potential for future residential development of the area, and other sensitive receptors;
Potential for introduction and / or spread of weeds; Risks of exposure of workers to high biting insect numbers; Environmental risks associated with waste streams and waste management practices; Risks associated with transport, handling and / or storage of reagents, products and / or
hazardous material; Public health and safety risks associated with siting a potential major hazard facility
adjacent to Darwin Harbour; and Potential for impacts on service infrastructure and service supply capacities, due to Project
demands.
The Project was referred under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and on 4 January 2016 it was determined to constitute a controlled action requiring assessment under the EPBC Act, under the bilateral agreement between the Australian and Northern Territory (NT) Governments. The controlling provisions included the likely significant impact on:
Listed threatened species and communities (sections 18 & 18A); and Listed migratory species (sections 20 & 20A).

Environmental Factors and Objectives
The NT EPA Environmental Factors and Objectives Guideline (NT EPA, 2018) was developed to improve certainty and increase transparency within the Environmental Impact Assessment (EIA) process. The 13 environmental factors are categorised under five themes of: Land, Water, Sea, Air and People and Communities.
The Terms of Reference (ToR) for the Project (NT EPA, 2016) was released by the NT EPA prior to the publication of NT EPA (2018). Therefore, the ToR does not identify specific Environmental Factors that the EIS must address. Discussions between the NT EPA and the Proponent subsequent to publication of NT EPA (2018) have identified the EIS must address the three factors and corresponding objectives identified by the NT EPA within the theme ‘Sea’ presented in Table 1.
Table 1 Environmental factors and objectives for the theme ‘Sea’ addressed in this report
Theme Factor Objective
Sea Marine Flora and Fauna Protect marine flora and fauna so that biological diversity and ecological integrity are maintained
Benthic Habitat and Communities
Protect benthic communities and habitats so that biological diversity and ecological integrity are maintained
Marine Environmental Quality
Maintain the quality and productivity of water, sediment and biota so that environmental values are protected.
Objectives
TNG commissioned O2 Marine (O2M) to undertake desktop review and marine environmental investigations of Sea relevant themes to support the EIS and Project approvals. Impact and assessment relies on knowledge of the existing environment of the Project area. For instance, in order to determine which habitats and biota are being affected by disturbance, their distribution and diversity has to be understood. Furthermore, the types of impacts and their severity and consequence for the whole ecosystem can only be evaluated on the background of a comprehensive understanding of the ecological context.
This document is intended to characterise the Marine Environmental Quality that may be impacted by the proposal. This document provides an account of the Water and Sediment Quality of the Study Area using historic studies, long term monitoring datasets and a site validation sampling event. The specific objectives of this report are to address specific recommendations within the ToR, including to:
Describe the beneficial uses and water quality objectives for Darwin Harbour (Elizabeth River / East Arm);
Describe the water quality of local water bodies (i.e. Estuarine / marine waters); and Describe existing temporal variations in suspended solids and parameters potentially impacted
by the Project, to serve as baseline data.

2. Existing Environment
Darwin Harbour Region
The Darwin Harbour and surrounding catchments are located in the wet-dry tropics of Northern Australia. The catchment of Darwin Harbour covers an area of approximately 3,230 km2 comprising of a land area of 2,010 km2 and an estuary area of 1,220 km2 at the high-water mark (NRETAS 2010).
Darwin city supports the largest concentration of the Northern Territory population. The City of Palmerston, south of Darwin, is also subject to increasing urban development. The population of the Darwin Region is ~140,000 as of 2019 and projected to grow to ~165,000 persons by 2026.
The Darwin wet season extends from November to March and its effects on harbour water quality (due to high surface runoff from the land) can last until April or May depending on rainfall. Dry season climate conditions prevail from May to September.
Marine Environmental Quality
The process for setting marine and freshwater quality objectives is based on the national framework outlined in the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZG 2018). The national document provides a framework that allows the user to move beyond a single-number conservative value, to guidelines and objectives that can be refined according to local environmental conditions. It is within this context that the Darwin Harbour region guidelines and objectives have been initiated and will be progressively enhanced.
The National Water Quality Management Strategy (NWQMS) was introduced in 1992 in response to growing community concern about the condition of the nation’s water resources and the need to manage them in an environmentally sustainable way.
Locally derived guidelines and objectives are the priority preferred ambient quality benchmarks as envisaged by the NWQMS. The Australian and New Zealand Guidelines for Fresh and Marine Water provide default values for a range of water quality parameters in the absence of locally or regionally derived reference values.
2.2.1. Relevant Northern Territory Guidelines
The Northern Territory (NT) Department of Natural Resources, Environment, The Arts and Sport (NRETAS) developed the Water Quality Objectives for the Darwin Harbour Region (NRETAS 2010) to commence the implementation of the National Water Quality Management Strategy. The key aim of this document was to identify a ‘suite of Water Quality Objectives that relate to the beneficial uses and environmental values of the waterways has been developed to provide some preliminary benchmarks against which various attributes of the health and condition of these waterways can be measured and reported’ (NRETAS 2010). These Water Quality Objectives, along with the key Beneficial Uses (BUs), were declared by the NT parliament in NT Government Gazette: no. G27, 7 July 2010.
13 TNG Limited - Darwin Industrial Processing Facility Marine Environmental Quality Site Investigation
19WAU-0007 R190214
This supported the development of the Darwin Harbour Water Quality Protection Plan (WQPP) (DLRM 2014) which sought to further implement the national strategy, and in particular the national Framework for Marine and Estuarine Water Quality Protection, through identification of specific actions relevant to the protection of the water quality within Darwin Harbour. The WQPP ‘aims to support good management and sustainable development through its focus on protecting Darwin Harbour waterways from excessive sediment and nutrient inputs’.
Whilst the WQPP and the declared Water Quality Objectives primarily focus on water quality and key identified threats such as nutrients and suspended sediment inputs to Darwin Harbour, they are applicable to the Project as primary guidelines for interpretation of water quality criteria relevant to the Darwin Processing Facility.
Beneficial Uses & Environmental Quality Objectives
Environmental Values are defined in ANZG (2018) as “Particular values or uses of the environment that are important for a healthy ecosystem or for public benefit, welfare, safety or health and which require protection from the effects of pollution, waste discharges and deposits”. The NT Water Act 1992 has defined and declared each of the NTs environmental values or uses, classifying them as BUs. BUs for Darwin Harbour were declared in NT Government Gazette: no. G27, 7 July 2010.
NREATAS (2010) defines Environmental Quality Objectives (EQOs) for water quality as high level management objectives described as ‘the water quality needed to protect and sustain each of the environmental values and beneficial uses identified’ and ‘intended for the community, local councils and government agencies to use in catchment management and land use planning activities’. While this description is primarily focused on water quality, rather than marine environmental quality, for the purposes of this assessment substitution of ‘marine environmental quality’ in place of ‘water quality’ is in keeping with the philosophy of EQOs in their application to the protection of marine environmental quality. EQOs for Darwin Harbour are defined in NRETAS (2010).
Three BUs and four corresponding EQOs apply to the Darwin Harbour area and are presented in Table 2
.
Table 2
Beneficial Uses and Environmental Quality Objectives applicable to the Darwin Harbour Region
Beneficial Uses Environmental Quality Objectives
Environment EQO1: To maintain and protect the ecological condition of marine, estuarine and freshwater ecosystems of the Darwin Harbour Region. EQO1 is split into four sub- objectives, being: High Conservation Value, Slightly to Moderately Disturbed and Highly Disturbed (Refer Section 2.3 below).

2.2.2. Previous Investigations
A number of studies have been undertaken to characterise the extent and better understand the environmental value and importance of the marine environmental quality within Darwin Harbour. The results of many of these studies are publicly available and have been used to characterise, map and describe the environmental values and importance of the water and sediment quality in the Project area.
O2M completed a comprehensive desktop review of the water and sediment quality in the Project area as a preliminary component of this report, using information derived from surveys undertaken for previous coastal development projects in Darwin, relevant scientific literature, and other studies commissioned by government authorities.

Water Quality
The marine water quality in Darwin Harbour and Elizabeth River (up to Elizabeth River Bridge) is regarded as good to excellent, especially in comparison to waterways surrounding other major Australian cities. Darwin Harbour is one of the least-disturbed working harbours around the Australian coastline (DLRM, 2014) The area is a valued tropical coastal environment that is home to most of the NT resident’s and the country of the Larrakia people. There is no evidence of widespread water or sediment pollution in the Harbour, although there is some localised pollution around the industrial estates (DLRM 2014).
15 TNG Limited - Darwin Industrial Processing Facility Marine Environmental Quality Site Investigation
19WAU-0007 R190214
Darwin Harbour is macro-tidal; however, the upper estuary reaches are not well-flushed and are most vulnerable to pollution. The Elizabeth River estuary is a major tributary of Darwin Harbour and the area surrounding the estuary is subject to increasing urban and industrial development. The catchments of several suburbs drain into Mitchell Creek and Brooking Creek which are both tributaries of the Elizabeth River estuary (URS 2010).
Due to urban developed in the Darwin wide metropolitan area there has been an increase in nutrients and sediments entering Darwin’s Harbour waterways above natural levels. Double the volume of stormwater runoff in wet season compared to an undisturbed landscape (Skinner et al 2009).
Increased nutrient loads in waterways can promote the growth of phytoplankton (microscopic plants) which can produce algal blooms and be toxic to marine life. There is also a potential impact on human health and odour issues from surface scum on the water. In areas of higher nutrient levels, sediment can store the nutrients changing the composition of sediment fauna and flora. Additionally, higher nutrient concentrations may also promote excessive growth of macroalgae and epiphytes which can smother seagrass and coral. Mangroves are important in trapping and recycling nutrients within the mangrove system.
Darwin Harbour has naturally high levels of suspended sediments due to it being a tide dominated estuary with large tidal movements, strong currents and large volume of mangrove sediments.
Some examples of anthropogenic influences around Darwin Harbour on water and sediment quality include:
INPEX and ConocoPhillips operations; Darwin Port operations at EAW; Historical Industrial activities at Darwin Waterfront; Power and Water Corp wastewater discharges; and Sewage outfall from wastewater treatment plant at Larrakeyah.
2.3.1. Physicochemical Characteristics
A significant amount of baseline water quality data has been collected for Darwin Harbour and the associated estuarine river systems. This data is discussed below to provide baseline context for the proposed Darwin Processing Facility.
Water quality monitoring of physicochemical parameters (Dissolved oxygen, salinity, pH, turbidity, total suspended solids) undertaken by INPEX during 2016-2017 provides the most recent and spatially-relevant long-term dataset to provide a summary of baseline physicochemical conditions in the vicinity of the Project Area. These results are discussed below together with the results of other Darwin Harbour water quality studies. The GREENCAP (2017) monitoring locations are shown in Figure 2.
Water Temperature
Water temperatures in Darwin Harbour are typically high, and some seasonal variations do occur. Temperatures are lowest (23°C) in June-July and highest (33°C) in October-November (Padovan 1997). Water temperature measured in the nearshore development area by URS (2008) ranged from
16 TNG Limited - Darwin Industrial Processing Facility Marine Environmental Quality Site Investigation
19WAU-0007 R190214
23.5 to 32.7°C, with an average temperature of 30.6°C in the wet season and 24.5°C in the dry season (URS 2009).

19WAU-0007 R190214
Figure 2 INPEX Offsite Monitoring Locations 2016-2017 (Source: GREENCAP 2017)
Dissolved Oxygen
Harbour waters remain well oxygenated throughout the year, with dissolved oxygen (DO) levels ranging from 54% to 103% saturation, with a median typically around 84% (GREENCAP 2017; Padovan 1997).
In a study by Padovan (1997) no seasonal effects were observed, and there were minor changes in oxygen levels across multiple locations in the main body of the Harbour. Similarly, GREENCAP (2017) found that dissolved oxygen levels varied more greatly between years than seasons, although DO levels were generally higher in the Dry season. GREENCAP (2017) also determined that the DO patterns were consistent across both impact and reference monitoring sites (Figure 2), indicating that INPEX operations had no effect on DO patterns.
Salinity
Salinity in Darwin Harbour varies considerably during the year, particularly in East, Middle and West Arms where freshwater influence is greatest during the wet season. Seawater has a global average salinity of 35 parts per thousand (ppt) and Darwin Harbour is no different with median salinity ~35 ppt with surface and bottom depths having similar levels. Salinity tends to be higher in the dry season owing to increased evaporation and less freshwater inflow (URS 2010).
Salinities in the Elizabeth River fluctuate significantly due to the influence of freshwater input from land-based catchments during the wet season flooding the rivers feeding Darwin Harbour. This overlies the more dense, higher saline water from the Harbour area, forming a ‘salt wedge’ typical of estuarine systems. Parry and Munksgaard (1995) reported salinities on the bottom of the Harbour to be as much as 12 ppt higher than on the surface. As the rains cease, runoff decreases and salinities return to their higher dry-season levels (Parry & Munksgaard 1995) (URS 2010).
GREENCAP (2017) reported salinity from monitoring locations in the vicinity of Bladin Point and the mouth of the Elizabeth River (Figure 2) as ranging annually from 8.74 to 39 ppt, with an median of 35.4 ppt. Median monthly salinity (38.2 ppt) was highest in November and began deceasing from December onwards to median monthly salinities during the wet season as low as 24.3 ppt (GREENCAP 2017).
Turbidity & Total Suspended Solids (TSS)
Tides have a marked effect on water clarity in the Harbour (i.e. Turbidity range due to tidal influence between 1 – 50 Nephelometric Turbidity Units (NTU)), with waters of neap tides being the clearest, while spring tides carry quantities of sediment from the fringing mangroves (DHAC 2007; GREENCAP 2017). GREENCAP (2017) also observed that high wet season rainfall events and the subsequent sediment runoff have a marked effect on turbidity and total suspended solids.
Darwin Harbour has naturally high levels of suspended sediments due to it being a tide dominated estuary with large tidal movements, strong currents and a large area of riparian mangrove sediments. Further sediment loads can enter the Harbour from soil erosion from urban and rural development. Excessive sediments can smother and contribute to the loss of seagrass, coral and other fauna and flora.
18 TNG Limited - Darwin Industrial Processing Facility Marine Environmental Quality Site Investigation
19WAU-0007 R190214
The areas with the highest natural sedimentation are in the upper reaches of East and Middle Arms. Medium levels of sedimentation occur in the seaward end of West Arm and the lowest levels are in the more open water areas such as EAW and Larrakeyah to the seaward boundary of the Harbour (DHAC 2007).
It is estimated that 60% of the Harbour’s sediments originate from offshore. The remainder is deposited by rivers and creeks, derived predominantly from erosion of channel walls. Direct contribution to the Harbour from sheet erosion is likely to be limited because of the very low hillslope gradients adjacent to the Harbour (DHAC 2007).
Turbidity is highest during spring tides when current velocity, and therefore capacity of the water to move sediment, is greatest (DHAC 2007). During the spring-tide cycle, turbidity is greatest at the midpoint between high and low water, and lowest at slack water. Turbidity is higher in the wet season than the dry season because of the influx of terrigenous sediments to Harbour waters through the rivers and, to a lesser extent, from surface-water sheetflow.
GREENCAP (2017) reported turbidity levels in 2016-2017 to range from 0.1 to 20.9 NTU, with a median of 4.45 NTU. Whilst TSS levels during the same period ranged from <1 to 55 mg/L, with a median of 8.8 mg/L.
Turbidity levels recorded in the Ichthys nearshore development area by URS (2008) were up to 73.6 NTU, with a mean reading of 6.9 NTU. Predictably, higher NTU values were found at the bottom of the water column than at the surface, with higher levels also being recorded in the wet season when compared with the dry. During ebb tides turbidity levels were higher upstream than in the Harbour; this was reversed during flood tides (URS 2010).
pH
The pH reported by GREENCAP (2017) around the mouth of the Elizabeth River and Bladin Point, between 2016-2017 ranged from 6.89 to 8.67, with a median of 7.85. However, Padovan (1997) reported a much narrower range (8.3–8.6 with a mean of 8.5) for the main body of Darwin Harbour. Both studies observed very little seasonal or spatial variation in pH, although GREENCAP (2017) observed significant rainfall events to result in a decrease in pH of up to 0.9 pH units.
Measurements in the nearshore development area by URS (2009) recorded a mean pH of 8.4, and a range from pH 7.8 to 9.2. In the upper reaches of the Harbour, mean pH levels were found to be lower (more acidic), with pH levels increasing (becoming more alkaline) in the main body of the Harbour in both wet and dry season sampling. No significant difference in pH attributable to water column position or tidal state was observed (URS 2009).
2.3.2. Nutrients
Padovan (1997; 2002) and Sly et al. (2002) found total nitrogen in the main body of the Harbour to be in the range 0.2–0.6 mg/L. The concentration of total nitrogen in most of the inflowing river waters was similar to that found in the Harbour and therefore wet season inflows are not expected to affect nitrogen concentrations in the main waterbody (Padovan 1997, 2003). Phytoplankton is an important water quality measure as its abundance and composition are directly influenced by environmental factors including nutrients and light. The abundance of phytoplankton is typically quantified through the
19 TNG Limited - Darwin Industrial Processing Facility Marine Environmental Quality Site Investigation
19WAU-0007 R190214
enumeration of cell numbers and through the measurement of chlorophyll-a, the main light absorbing pigment used in photosynthesis (URS 2010).
Monitoring undertaken by INPEX in 2016-2017 reported the following results for nutrients in Darwin Harbour waters (GREENCAP 2017):
Ammonia ranged from <5 to 180 µg/L, with an annual median of 12 µg/L, with the highest concentrations occurring during March (median 18 µg/L) and the lowest in the December (median 6 µg/L);
Total nitrogen ranged 14 to 2,600 µg/L with an annaul median of 160 µg/L, and showed little variation observed between mid or upper estuary waters, or between seasons;
Total phosphorous ranged between <5 to 230 µg/L, with an annaul median of 28 µg/L (GREENCAP 2017); and
With the exception of Total Nitrogen, elevated nutrient levels were generally recorded during the wet season and were attributed to excess surface water runoff.
2.3.3. Heavy Metals
Limited information exists on the concentration of metals present in the waters of Darwin Harbour, However, Skinner et al. (2009) notes that the Darwin Harbour urban and rural zone catchments provide a potential source of aluminium, arsenic, cadmium, chromium, copper, nickel, lead and zinc.
2.3.4. Hydrocarbons and Pesticides
There is no evidence of hydrocarbon or pesticide pollution in the waters of Darwin Harbour (DHAC 2007).
Sediment Quality
Sediments play a key role in the geochemical and biological processes of an estuarine ecosystem such as Darwin Harbour. Sediments can act as sinks for organics and metals that enter the rivers feeding Darwin Harbour. However, Darwin Harbour is generally regarded as one of the least-disturbed working harbours around the Australian coastline (DLRM, 2014).
2.4.1. Physical Characteristics
Darwin Harbour sediments can be divided into four types (Michie 1988):
Terrigenous gravels, which occur primarily in the main channel and central channels of tributaries. This demonstrates the influence of tidal movement, bathymetry and potential transport capacity in these regions (Fortune 2006);
Calcareous sands with greater than 50% biogenic carbonate, which are among or close to the small coral communities at East Point, Lee Point and Channel Island. Biogenic carbonate sediments, largely derived from molluscan shell fragments, also occur in spits and shoals close to the Harbour mouth;
Terrigenous sands on beaches and spits. This type of sediment is predominantly quartz and clay, with 10–50% carbonate, again largely derived from molluscs; and

Mud and fine sand on broad, gently inclined intertidal mudflats that occur in areas characterised by low current and tidal velocities, such as in Kitchener Bay (prior to the construction of the Darwin City Waterfront). The spatial extent of these surfaces is sometimes difficult to determine because of the gradual transition between muddy, sandy and coarser sediments and sediment movement associated with large tidal influences (Fortune 2006).
2.4.2. Heavy Metals
The following physical factors may bring about the exchange of heavy metals between water and sediments:
Bioturbation in sediments that may tend to redistribute heavy metals in the profile; and Local hydrodynamic effects can cause sediment re-suspension.
Several major projects have undertaken detailed studies of heavy metal concentrations in sediment in the vicinity of Darwin Harbour and East Arm.
Fortune (2006) undertook a detailed study of heavy metal concentrations in sediments throughout the Harbour. Several sites in the study had concentrations of metals above ISQG-Low values or were considered elevated;
Sampling by URS in 2008 found that metal concentrations recorded in East Arm surface sediments were generally found to be below the screening concentration, with the exception of arsenic, chromium and mercury. Arsenic concentrations were elevated above the maximum concentration at six sites;
A study in 2010 by the Australian Institute of Marine Science (Parry 2010) of the sediments in the immediate area of the copper concentrate loadout at EAW found elevated copper concentrations compared to background levels for Darwin Harbour;
Testing in the vicinity of EAW by AECOM in 2010 also found concentrations of arsenic and chromium elevated above the ISQG-Low level, with all other metals tested returning levels below the ISQG-Low level (AECOM, 2011). Similar to the conclusions drawn in previous studies, the elevated concentrations of arsenic, chromium and nickel detected in Darwin Harbour sediments by URS and AECOM are considered to be attributable to the local geology, and not to contamination by anthropogenic sources. These heavy metals are unlikely to be bioavailable to any significant extent and would not result in toxic effects to marine biota; and
DENR (2012) undertook comprehensive sampling across nearly 300 locations. Again, only arsenic was found to be elevated above ANZECC (2000) guidelines, with most metal concentrations being reported below the LoR for the majority of Darwin Harbour. However, a notable exception was concentrations of copper, lead and zinc being up to 20-29% higher in the tidal flat sediments adjacent to Darwin City than in other areas of Darwin Harbour.
2.4.3. Hydrocarbons
As discussed previously there are several sites of potential anthropogenic sources. Specifically, for hydrocarbons, risk around Darwin Harbour include:
Seasonal stormwater inflow from Darwin and Palmerston storm water drainage networks;

19WAU-0007 R190214
Underground pressurised fuel lines to the Fort Hill Wharf; INPEX and ConocoPhillips Facilities; The Naval Fuel Installation, Stokes Hill; Former fuel storage at the Channel Island Power Station; Bulk hydrocarbon storage at EAW; Bulk hydrocarbon storage at the Darwin LNG plant; and Inventories in recreational, commercial vessels and shipping.
The NAGD screening concentration for petroleum hydrocarbons in sediments is 550 mg/kg (DEWHA 2009). A survey by URS (2004) sampled 12 sites around the Darwin Wharf Precinct and one reference site in Elizabeth River. The highest concentrations of total petroleum hydrocarbons (TPH) recorded (11–16 mg/kg) were present at sites in Kitchener Bay and Fort Hill Wharf. Concentrations at the remaining sites were between 6 and 10 mg/kg. Petroleum hydrocarbons were also present at the reference site (Elizabeth River), though the concentration (4.9 mg/kg) was lower than in any of the samples taken during the Darwin Wharf Precinct Study. In sampling conducted in 2008, URS detected TPH, particularly in the C15–C28 range, in surface sediments at a number of sites in East Arm. However, the BTEX compounds were below LoRs at all sites, as were polycyclic aromatic hydrocarbons (PAHs) at the majority of sites (URS 2009). Sampling by AECOM at the proposed INPEX dredging sites in 2010 (AECOM, 2011) did not return reportable levels of BTEX, PAHs or TPH.
2.4.4. Acid Sulfate Soils (ASS)
Marine and estuarine sediments containing significant amounts of sulphur, present as sulphides, have the potential to generate acidity when exposed to oxygen. Such sediments are known to occur in the mangrove soils of Darwin Harbour. Their presence and potential acid generation capacity within construction areas will be determined in pre-construction monitoring and the appropriate management measures implemented.

3. Site Investigation Methods
O2M undertook two field surveys on 27th - 28th March 2019 and 22nd May 2019 to collect information on marine environment quality of the study area. This included:
Water quality sampling and profiling took place between 27th and 28th March 2019; and Sediment quality sampling took place on 22nd May 2019.
The purpose of this investigation was to evaluate the water and sediment quality of the Project area in the context of the extensive historic datasets. As such, the key indicators applied during the field survey attempt to enable comparison with existing methods and data collected which included:
Physicochemical indicators – pH, water temperature, salinity, dissolved oxygen, turbidity; Toxicants in water – Heavy metals, nutrients, hydrocarbons; and Toxicants in sediment – Heavy metals, hydrocarbons, particle size distribution (PSD).
The eight water profiling locations and six water and sediment sampling locations are listed in Table 3 and shown in Figure 4.
The sites were selected to build a detailed description of the immediate area alongside the Project in the Elizabeth River.

Water Column Profiling
Water profiling was undertaken using a YSI ProDSS multiparameter sonde measuring the following parameters from the surface to the seabed. Global Positioning System (GPS) on board the vessel allowed for measurement to be taken at precise locations along the Elizabeth River.
Water Temperature; Depth; Salinity; Turbidity; Dissolved Oxygen; and pH.
Water Sampling & Analysis
Water samples were collected from the near-surface (0.5 m depth) using a 5L Niskin Bottle. GPS on board the vessel allowed for measurement to be taken at precise locations along the Elizabeth River.
Water samples were sent to a NATA accredited laboratory for analysis of:
Total Metals (including Mercury); Nutrients (Chlorine, Nitrate, Ammonia, Phosphorous); Hydrocarbons; BTEXN; PAH; and E.Coli & Faecal Coliforms.
Sediment Sampling & Analysis
Surficial sediment samples were collected using a Ponar Sediment Grab. GPS on board the vessel allowed for measurement to be taken at precise locations along the Elizabeth River.
Sediment samples were sent to a NATA accredited laboratory for analysis of:
Total Metals (including Mercury); Hydrocarbons; BTEXN; and PAH.
QA/QC Assessment
The precision of the water and sediment analyses was determined by quantifying the differences between the concentrations of analytes in the QA/QC samples, using the method outlined in ANZG (2018).
25 TNG Limited - Darwin Industrial Processing Facility Marine Environmental Quality Site Investigation
19WAU-0007 R190214
Duplicate water samples were collected at one location. Field triplicate split sediment samples were collected at one location and sent to two NATA accredited laboratories for analysis.
Duplicates are two sub-samples from one sample replicate and are used to test the precision (or repeatability) of the analysis. The relative percentage difference (RPD) between the primary and duplicate sample is calculated as:
If the RPDs are less than 35% then field and laboratory procedures are considered of acceptable quality and meaningful conclusions can be drawn from the data.
Three interlaboratory triplicates were collected for one sediment sample. This involves collecting three sub-samples from one same replicate. The relative standard deviation (RSD) was calculated as:
If the RSDs are less than 50% then field and inter-laboratory procedures are considered of acceptable quality and meaningful conclusions can be made with the data.

4. Results & Discussion
Water Quality
4.1.1. Physico-chemical Parameters
Water column profiles were collected at eight locations in the study area during both incoming and outgoing tide conditions. These results are presented in Figure 4 and discussed below.
Water Temperature
Temperature range across all locations was between 28.9°C to 29.9°C. These results are comparative to previous surveys in Darwin Harbour, where the average water temperature in the Wet Season (November – April) was reported as 30.6 °C (URS 2010; URS 2009). It is widely understood that water temperatures vary greatly between Wet and Dry Seasons in Darwin Harbour, therefore the temperatures observed in this study should not be considered as representative of year-round conditions.
Slight (i.e. <1 °C) temperature stratification was observed between surface and midwaters during incoming tide conditions at PR1 and P1 and during outgoing tide conditions at P1, P3, P6 and PR2.
Dissolved Oxygen
Dissolved oxygen (% Saturation) varied from 66% at PR6 to 84% at PR1. DO was lower near surface and higher at depth at all locations. DO was below the 80% Darwin Harbour WQO (NRETAS 2010) at all locations during outgoing tide conditions and at PR2, P6, P5, P4 and P2 during incoming tide conditions. The observed low DO conditions are most likely related to freshwater inputs causing stratification during the Wet Season.
Although the observed DO levels were low, they are generally comparable with previous results reported in URS (2010), which found that typical DO levels in the Darwin Harbour area were ~84% with slightly lower levels found further up the estuaries. This corroborates with O2M’s survey which found that DO at PR1, located closest to Darwin Harbour, had 84% saturation. However, values of 66% were recorded at P6 which is located further upstream in close proximity to Elizabeth River Bridge.
Salinity
Salinity at all locations was observed to increase with depth during outgoing tide conditions. Locations P1, P3, P4 and PR2 had clear changes in salinity from surface to the seabed indicating the denser saline water forming closer to the seabed and freshwater mixing at the surface, as would be expected from the formation of a salt wedge in an estuarine environment, particularly during the Wet season. Locations P2 and PR1 further downstream were generally more mixed and more saline than the upstream locations.
Conversely, during incoming tide conditions, only site PR2, located furthest upstream in the Elizabeth River, reported an increase in salinity from the surface (i.e. 24 ppt) to near the seabed (i.e.32 ppt). All other locations were well mixed throughout the water column during incoming tide conditions.

19WAU-0007 R190214
pH
The most acidic sites were PR2, P6 and P5 which had an average profile pH of 7.75 – 7.86, whilst sites PR1, P2 and P3 were slightly more alkaline with pH values of 8.04 – 8.12 respectively. All results were within the acceptable range (i.e. pH of 7 - 8.8) defined in the Darwin Harbour Water Quality Objectives (NRETAS 2010) and are consistent with pH measurements made in previous surveys of Darwin Harbour (URS 2010; URS 2009), which recorded a mean pH of 8.4 in Darwin Harbour and slightly lower pH levels (i.e. pH of between 7 – 8) further upstream in the adjoining estuaries.
Turbidity
Turbidity was variable for all locations during both incoming and outgoing tide conditions although was generally lower during outgoing tide conditions (i.e. turbidity range ~4 - 8 NTU) compared to incoming tide conditions (i.e. Turbidity range ~5 - 11 NTU). Turbidity increased with depth at all locations under both incoming and outgoing tide conditions. The observed turbidity range is typical for Darwin Harbour during the wet season which has previously been reported as a mean of 6.9 NTU in the vicinity of the Project area (URS 2010).

4.1.2. Laboratory Analysis Results
Results for the laboratory analysis of water samples are presented in Table 4 and discussed below.
Heavy Metals
Water samples collected by O2M along Elizabeth River provided results that only detected aluminium and manganese.
Aluminium varied between 90 µg/L at WSRef2 location to 170 µg/L at sites WS1 and WS4. Manganese varied from below LoR at WSRef1 to 15 µg/L at WSRef2.
All other metals reported results below the LoR. However, due to matrix interference3 in the laboratory, the analysis was not able to achieve the target LoR for most metals, resulting in the minimum reported values being above the Darwin Harbour WQOs (NRETAS 2010) for: Chromium, Cobalt, Copper, Lead, Silver and Zinc. It is noted that these reported levels are unlikely to be actual exceedances of the criteria and more likely related to limitations of the analysis for these particular samples.
Limited information is publicly available regarding concentrations of heavy metals in water.
Nutrients
Water samples collected by O2M along Elizabeth River showed that ammonia, nitrite and phosphorous were present at all locations, with both ammonia and phosphorus elevated at, or above the Darwin Harbour WQO (20 µg/L) at all locations. This result is consistent with other studies which have found nutrient enrichment, particularly ammonia and phosphorus to be present throughout Darwin Harbour, particularly during in the wet season (GREENCAP 2017).
Hydrocarbons
Concentrations of hydrocarbons (i.e. PAH, TRH, TPH & BTEX) were below the limit of reporting for all water samples collected. This result is consistent with previous studies in Darwin Harbour which recorded very limited evidence of any hydrocarbon contamination (GREENCAP 2017; URS 2010).
3 Matrix interference may occur due to variable salinity and total dissolved solid concentrations within water samples.

Sediment Quality
4.2.1. Laboratory Analysis Results
Sediment samples were collected at 6 locations along Elizabeth River (Figure 3). Results for the laboratory analysis of sediment samples are presented in Table 5 and discussed below.
Physical Characteristics
Sampling of the Elizabeth River channel locations WS2, WS3, WS4, WSRef1 & WSRef2 all comprised very similar composition of particle size being predominately sandy (i.e. Sand content ranged from 48 – 77%) with some gravel (i.e. Gravel content ranged from 9-38%). Site WS4 had the highest content of gravel (i.e. 38%). Site WS1, which was up a small creek feeding into the Elizabeth River was predominately sand with little to no gravel, but with a significant quantity of clay (i.e. 31%). All samples were within the typical range expected of sediments in Darwin Harbour and the associated estuarine river systems being dominated by fine sand particles which typically make up more than 50% of the sediment particle size composition (DENR 2012).
Heavy Metals
Concentrations of harmful heavy metal contaminants in sediments were generally low, with only WSRef1 reporting levels of Arsenic above the ANZG (2018) Default Guideline Value (DGV) (2018). All other metals were either below the relevant ANZG (2018) DGV, or do not have a specified DGV. For those values that do not have an DGV, Aluminium, Iron, Manganese and Vanadium were all noted as being present at moderate concentrations, but were consistent with the concentrations reported for previous studies (DENR 2012; Fortune 2006).
The results obtained through this site investigation are similar to previous studies of the Darwin Harbour sediments, which reported metal concentrations below the DGVs (Peerzada and Ryan 1988; Currey 1988; Hanley and Caswell 1995; Parry and Munksgaard 1995; Padovan 2002). AECOM (2011) sampled sediments in the vicinity of EAW and also detected elevated levels of arsenic and chromium above the relevant DGVs. DENR (2012) also detected arsenic above ANZECC (2000) guidelines values at several locations in Darwin Harbour. Further testing undertaken by AECOM in 2010 determined that the elevated arsenic levels were unlikely to be bioavailable to any significant extent that would result in toxic effects to marine biota. The elevated levels were considered characteristic of the local hydrogeology and were later detected in elevated groundwater samples collected by GREENCAP (2017).
Hydrocarbons
Total Petroleum Hydrocarbons (TPH) and Total Recoverable Hydrocarbons (TRH) were detected at WS2 and WSRef1 locations although levels of TPH were below the ANZG (2018) DGV. These sites are also located the furthest downstream from the Project area, towards Darwin Harbour. All samples analysed for BTEXN and PAH returned levels below laboratory LoR. These results are consistent with previous studies which found hydrocarbons in Darwin Harbour to generally be below the LoR (AECOM 2011; URS 2009).

QA/QC Assessment
4.3.1. Water Samples
Results of field QA/QC assessment for water samples are shown in Table 64. RPD was within acceptable limits (i.e. <35%) for all analytes except TKN and TN. However, the exceedance for these analytes was due to the very low levels reported. QA/QC results indicate that field sampling repeatability was acceptable.

5. Conclusion
Water Quality
Water quality within Darwin Harbour has been subject to numerous studies and monitoring programs, and a validation survey was undertaken in the vicinity of the Project area to provide context for the historic information. Typical water quality characteristics of the Project area include:
Water temperatures typically range from 23.5 – 32.7°C with an average of 30.6°C and 24.5°C in the wet and dry seasons, respectively. Values observed during the O2M site investigation were consistent with historical temperatures, with results between 28.9°C and 29.9°C during the March survey;
Dissolved oxygen typically ranges between 54-103%, averaging 84%. The O2M March 2019 survey observed dissolved oxygen values within this range (i.e. between 66-84%). Dissolved oxygen has been observed to decrease with respect to distance upstream, an observation conclusive within the O2M March 2019 survey results;
Salinity levels in Darwin Harbour are reported to range between 8.74 to 39 ppt, with a median of 35.4 ppt. Salinity varies considerably over the year and respect to distance upstream. Salinity averages 35 ppt, although salt wedges are typical of the mid to upper estuary areas with salinities identifies up to 12 ppt higher within bottom waters compared with surface waters during wet season. Salt wedge effects were observed during outgoing tides by O2 Marine, with greater mixing identified during incoming tides;
Turbidity and suspended sediments are naturally high, associated with the large tidal movements and strong currents. Turbidity is highest during spring tides, typically around the midpoint between high and low water when current velocity is greatest, and vice versa lowest during neap tides. Average turbidity increases during the wet season as a result of increase sediment loading due to high rainfall resulting in suspended sediments entering the system. Turbidity has been observed to range between 6.9 NTU and 73.6 NTU; although consistent with the O2M March 2019 survey which observed turbidity within the range of 4-11 NTU;
pH typically ranges between 7.8-9.2 with an average of 8.4. The results of the O2M March 2019 survey reported pH range at the low end of the typical range (i.e. 7.75-8.12). Little to no seasonal variation has previously been observed, however greater variability and higher pH has been observed in the upper reaches attributed to acidification processes occurring within from mangrove communities;
The result of the O2M March 2019 sampling confirmed that with the exception of total nitrogen, nutrient enrichment (i.e. elevated phosphorus and ammonia) is present in the vicinity of the Project area. In the past this finding has been most prevalent in the wet season and attributed to excess surface water runoff.
Limited information is available for heavy metal levels within Darwin Harbour waters. However, the March O2M survey confirmed that there is no heavy metal contamination in the vicinity of the Project area, with all metals reported below the DGV for SMD waters.
The waters surrounding the project are considered to have no known hydrocarbon or pesticide water quality issues, an observation consistent with the O2M March 2019 sampling results, which recorded these parameters generally below the LoR.

Overall the marine and estuarine waters of Darwin Harbour and the Project area are considered to be in good to excellent quality with limited evidence of anthropogenic impacts.
Sediment Quality
The sediment quality characteristics of the Project Area include:
Sediments within Elizabeth River sample locations comprised predominately of sand with some gravel;
Concentrations of metals sampled from surficial sediments within Darwin Harbour and the Project area are generally low, with arsenic being the only contaminant that is consistently reported to be elevated across multiple locations in the Harbour.
Elevated arsenic levels in sediments are thought to be attributed to local geology, not contamination from anthropogenic sources;
With the exception of arsenic, the O2 Marine (2019b) sediment survey found all metals to be below the ANZG (2018) DGV. However, historic surveys have found occasional samples to contain elevated levels of chromium, lead and copper in isolated areas of Darwin Harbour.
Concentrations of elevated metal contaminants (i.e. arsenic) are not thought to be bioavailable to any significant extent that would result in toxic effects to marine biota;
Low levels of TPH (11-16 mg/kg) have been detected in East Arm surrounding the wharf, although BTEX and PAHs were below the detection levels. Similarly, O2 Marine found that TPH and TRH within the lower reaches of Elizabeth River were below detection levels;
Actual Acid Sulphate Soils are known to exist in sediments, both sub- and inter- tidal, surrounding the Project Area and appropriate sampling and management would be required if disturbance of marine sediments is proposed.
Overall, sediment quality in Darwin Harbour and in the vicinity of the Project area is of good quality with limited evidence of anthropogenic impacts.

The recommended maximums for analytes in urine are taken from “2018 TLVs and BEIs”, as published by ACGIH (where available).
Australian Drinking Water Guidelines recommend that Thermotolerant Coliform, Faecal Enterococci, & E.Coli levels are less than1cfu/100mL. The recommended maximums are taken from "Australian Drinking Water Guidelines", published by NHMRC & ARMC2011.
Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds whichare similar to the analyte of interest, however are not expected to be found in real samples.
Surrogate Spike
This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortifiedwith analytes representative of the analyte class. It is simply a check sample.
LCS (LaboratoryControl Sample)
A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spikeis to monitor the performance of the analytical method used and to determine whether matrix interferencesexist.
Matrix Spike
This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selectedshould be one where the analyte concentration is easily measurable.
Duplicate
This is the component of the analytical signal which is not derived from the sample but from reagents,glassware etc, can be determined by processing solvents and reagents in exactly the same manner as forsamples.

Quality Control Definitions
Measurement Uncertainty estimates are available for most tests upon request.
Where sampling dates are not provided, Envirolab are not in a position to comment on the validity of the analysis whererecommended technical holding times may have been breached.
When samples are received where certain analytes are outside of recommended technical holding times (THTs), the analysis hasproceeded. Where analytes are on the verge of breaching THTs, every effort will be made to analyse within the THT or as soon aspracticable.
In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or 1 in 20 samples respectively, thesample volume submitted was insufficient in order to satisfy laboratory QA/QC protocols.
Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140% for organics (+/-50% surrogates) a
Duplicates: >10xPQL - RPD acceptance criteria will vary depending on the analytes and the analytical techniques but is typically inthe range 20%-50% – see ELN-P05 QA/QC tables for details; <10xPQL - RPD are higher as the results approach PQL and theestimated measurement uncertainty will statistically increase.
For VOCs in water samples, three vials are required for duplicate or spike analysis.
Spikes for Physical and Aggregate Tests are not applicable.
Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is generally extracted during sampleextraction.
Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency to meetor exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix spike recoveries forthe batch were within the laboratory acceptance criteria.

General Comments
The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house
developed procedures are employed in the absence of documented standards or by client request.
Where moisture determination has been performed, results are reported on a dry weight basis.
Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.
Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.
When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing
purposes.
Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.
CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.
LOR = Limit of reporting
^ = This result is computed from individual analyte detections at or above the level of reporting
ø = ALS is not NATA accredited for these tests.
~ = Indicates an estimated value.
Key :
MF = membrane filtrationl
CFU = colony forming unitl
Microbiological Comment: In accordance with ALS work instruction QWI-MIC/04, membrane filtration result is reported an approximate (~) when the count of colonies on the filtered membrane is outside the range
of 10 - 100cfu.
l
Benzo(a)pyrene Toxicity Equivalent Quotient (TEQ) per the NEPM (2013) is the sum total of the concentration of the eight carcinogenic PAHs multiplied by their Toxicity Equivalence Factor (TEF) relative to
Benzo(a)pyrene. TEF values are provided in brackets as follows: Benz(a)anthracene (0.1), Chrysene (0.01), Benzo(b+j) & Benzo(k)fluoranthene (0.1), Benzo(a)pyrene (1.0), Indeno(1.2.3.cd)pyrene (0.1),
Dibenz(a.h)anthracene (1.0), Benzo(g.h.i)perylene (0.01). Less than LOR results for 'TEQ Zero' are treated as zero.
l
EG020T : LOR raised for all samples due to possible sample matrix interference.l
MW006 and MW023: estimate (~) is reported where there are many non-target colonies; the typical colonies may be masked by overgrowth of non-target organisms. It may be informative to record this fact.l
MW023 is ALS's internal code and is equivalent to AS4276.9.l
MW006 is ALS's internal code and is equivalent to AS4276.7.l

General Comments
The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house
developed procedures are employed in the absence of documented standards or by client request.
Where moisture determination has been performed, results are reported on a dry weight basis.
Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis. Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.
Anonymous = Refers to samples which are not specifically part of this work order but formed part of the QC process lot
CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.
LOR = Limit of reporting
RPD = Relative Percentage Difference
# = Indicates failed QC

Laboratory Duplicate (DUP) Report
The quality control term Laboratory Duplicate refers to a randomly selected intralaboratory split. Laboratory duplicates provide information regarding method precision and sample heterogeneity. The permitted ranges
for the Relative Percent Deviation (RPD) of Laboratory Duplicates are specified in ALS Method QWI -EN/38 and are dependent on the magnitude of results in comparison to the level of reporting: Result < 10 times LOR:
No Limit; Result between 10 and 20 times LOR: 0% - 50%; Result > 20 times LOR: 0% - 20%.

Method Blank (MB) and Laboratory Control Spike (LCS) Report
The quality control term Method / Laboratory Blank refers to an analyte free matrix to which all reagents are added in the same volumes or proportions as used in standard sample preparation. The purpose of this QC
parameter is to monitor potential laboratory contamination. The quality control term Laboratory Control Spike (LCS) refers to a certified reference material, or a known interference free matrix spiked with target
analytes. The purpose of this QC parameter is to monitor method precision and accuracy independent of sample matrix. Dynamic Recovery Limits are based on statistical evaluation of processed LCS.

Analysis Holding Time Compliance
Holding times for VOC in soils vary according to analytes of interest. Vinyl Chloride and Styrene holding time is 7 days; others 14 days. A recorded breach does not guarantee a breach for all VOC analytes and
should be verified in case the reported breach is a false positive or Vinyl Chloride and Styrene are not key analytes of interest/concern.
Holding time for leachate methods (e.g. TCLP) vary according to the analytes reported. Assessment compares the leach date with the shortest analyte holding time for the equivalent soil method. These are: organics
14 days, mercury 28 days & other metals 180 days. A recorded breach does not guarantee a breach for all non-volatile parameters.
If samples are identified below as having been analysed or extracted outside of recommended holding times, this should be taken into consideration when interpreting results.
This report summarizes extraction / preparation and analysis times and compares each with ALS recommended holding times (referencing USEPA SW 846, APHA, AS and NEPM) based on the sample container
provided. Dates reported represent first date of extraction or analysis and preclude subsequent dilutions and reruns. A listing of breaches (if any) is provided herein.

General Comments
The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house
developed procedures are employed in the absence of documented standards or by client request.
Where moisture determination has been performed, results are reported on a dry weight basis.
Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.
Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.
When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing
purposes.
Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.
CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.
LOR = Limit of reporting
^ = This result is computed from individual analyte detections at or above the level of reporting
ø = ALS is not NATA accredited for these tests.
~ = Indicates an estimated value.

General Comments
The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house
developed procedures are employed in the absence of documented standards or by client request.
Where moisture determination has been performed, results are reported on a dry weight basis.
Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis. Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.
Anonymous = Refers to samples which are not specifically part of this work order but formed part of the QC process lot
CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.
LOR = Limit of reporting
RPD = Relative Percentage Difference
# = Indicates failed QC

Laboratory Duplicate (DUP) Report
The quality control term Laboratory Duplicate refers to a randomly selected intralaboratory split. Laboratory duplicates provide information regarding method precision and sample heterogeneity. The permitted ranges
for the Relative Percent Deviation (RPD) of Laboratory Duplicates are specified in ALS Method QWI -EN/38 and are dependent on the magnitude of results in comparison to the level of reporting: Result < 10 times LOR:
No Limit; Result between 10 and 20 times LOR: 0% - 50%; Result > 20 times LOR: 0% - 20%.

Method Blank (MB) and Laboratory Control Spike (LCS) Report
The quality control term Method / Laboratory Blank refers to an analyte free matrix to which all reagents are added in the same volumes or proportions as used in standard sample preparation. The purpose of this QC
parameter is to monitor potential laboratory contamination. The quality control term Laboratory Control Spike (LCS) refers to a certified reference material, or a known interference free matrix spiked with target
analytes. The purpose of this QC parameter is to monitor method precision and accuracy independent of sample matrix. Dynamic Recovery Limits are based on statistical evaluation of processed LCS.

Analysis Holding Time Compliance
Holding times for VOC in soils vary according to analytes of interest. Vinyl Chloride and Styrene holding time is 7 days; others 14 days. A recorded breach does not guarantee a breach for all VOC analytes and
should be verified in case the reported breach is a false positive or Vinyl Chloride and Styrene are not key analytes of interest/concern.
Holding time for leachate methods (e.g. TCLP) vary according to the analytes reported. Assessment compares the leach date with the shortest analyte holding time for the equivalent soil method. These are: organics
14 days, mercury 28 days & other metals 180 days. A recorded breach does not guarantee a breach for all non-volatile parameters.
If samples are identified below as having been analysed or extracted outside of recommended holding times, this should be taken into consideration when interpreting results.
This report summarizes extraction / preparation and analysis times and compares each with ALS recommended holding times (referencing USEPA SW 846, APHA, AS and NEPM) based on the sample container
provided. Dates reported represent first date of extraction or analysis and preclude subsequent dilutions and reruns. A listing of breaches (if any) is provided herein.
