1. Introduction

1.1 General Introduction

AECOM Ireland Limited (AECOM) is pleased to present this report to PPI Adhesive Products Limited

(PPI) detailing groundwater monitoring undertaken in September and November 2016 at the IDA

Industrial Estate, Cork Road Waterford. This report has been prepared in accordance with AECOM

proposal reference OPP-544131, dated 02 September 2016; and authorised by PPI under purchase

order number NM 016014.

The AECOM team for 2016 comprised the following:

• Project Director: Kevin Forde

• Project Manager: Edel O’Hannelly

• Field Scientist: Colin Fitzgerald

Laboratory analysis of samples was subcontracted to Exova Jones Environmental Ltd., Deeside, UK.

The laboratory certificates are attached in Appendix A.

1.2 Background

The PPI facility operates under the terms of an Integrated Pollution and Control (IPC) licence issued

by the Environmental Protection Agency (EPA) (IPC licence P0093-01 issued in May 1997).

The site is required by the EPA to complete groundwater monitoring on an annual basis from selected

groundwater monitoring wells located on site and across the industrial estate. Annual monitoring is

focussed on the presence of chlorinated hydrocarbons in groundwater and parameters indicative of

natural attenuation processes. Up to 1991, trichloroethene (TCE) a chlorinated hydrocarbon and

volatile organic compound (VOC) was used in the production process on site. Since the mid-1990s

TCE and compounds related to its biodegradation, in addition to other VOCs, have been detected in

groundwater from beneath the site.

Annual monitoring completed in 2014 detected separate-phase fuel hydrocarbons in one monitoring

well. In June 2015, the EPA requested (EPA request for information RI003936) that groundwater from

wells on-site and off-site down-gradient wells, be sampled and analysed for fuel hydrocarbons. This

was completed in 2015 and sampling of groundwater from selected wells for fuel hydrocarbons has

also been included in the 2016 groundwater monitoring ground.

This report presents results for the annual groundwater monitoring undertaken in 2016.

1.3 Objectives

The primary objective was to comply with the site’s annual groundwater monitoring requirements

under P0093-01 and EPA request for information RI003936. Included in this was an assessment of

hydrogeological conditions beneath the site for 2016 and long term concentration trends for

chlorinated hydrocarbons in groundwater.

1.4 Scope of Work

The following tasks were completed to address the site’s groundwater monitoring requirements for

2016:

• Task 1 – fieldwork

• Task 2 – laboratory analysis

• Task 3 – data assessment and reporting

2. Site Setting and History

2.1 Site Description

The site is located in the IDA Industrial Estate, Cork Road, Waterford, see Figure 1, and landuse in

the immediate vicinity of the site is industrial. The facility produces an extensive variety of technical

self-adhesive tapes for a wide range of applications in many sectors, including the electrical,

electronic, aerospace, photographic and audio/video areas.

The site is situated among other small industrial units, and consists of a number of small offices to the

front (south) of the building with the bulk of the building used for manufacturing. There is also a yard,

divided into the east and west yards, to the rear (north) of the site. The yards occupy approximately

25% of the site as a whole.

A map illustrating the locations of some of the neighbouring businesses within the IDA Industrial

Estate is presented in Figure 2.

2.2 Site Geology

Results of previous drilling works on-site confirm indications from published sources.

Overburden subsoils consist of made ground overlying natural orange/brown, firm to stiff, slightly

gravelly clay. Bedrock geology beneath the site has been mapped as rhyolithic volcanics and grey

and brown shale/slate of the Campile Formation, (Geological Survey of Ireland (GSI), (1995) Bedrock

Geology Map 1:100,000 Sheet 23). Intrusive site investigations have found weathered shale/slate

bedrock to be present from 6.0 m - 6.5 m below ground level (bgl) in the rear yard area, with depth to

weathered bedrock increasing slightly to the south (6.8 m bgl) and more substantially off-site to the

east (13.6 m bgl).

2.3 Hydrology

The nearest surface water features to the site are the Lisduggan Stream and St. John’s River.

The Lisduggan Stream lies about 500 m north-east of PPI and flows from north-west to south-east.

The stream flows into the St. John’s River approximately 2 km east of the site. Groundwater is not

expected to discharge into the Lisduggan Stream, as it is considered to be more of a shallow drainage

channel and bedrock groundwater is considered to be too deep (at >10 m below ground surface) to

be hydraulically connected to it.

The River Suir lies approximately 3 km north of the site and flows eastwards for approximately 12 km

before discharging into Waterford Harbour. St. John’s River flows into the River Suir in the centre of

Waterford, approximately 3.5 km north-east of the PPI site.

Neither the Lisduggan Stream, St. John’s River nor the River Suir are used for potable supply down-

gradient of the PPI site.

2.4 Hydrogeology

According to GSI online maps, the bedrock aquifer in the area is classified as a Regionally Important

Aquifer – fissured bedrock (Rf). Groundwater vulnerability in the industrial estate is assessed as

Moderate to High by the GSI.

Groundwater flow within the bedrock aquifer is complex due to local and regional topography, local

groundwater use, and the likely presence of fault zones and/or volcanic dykes. It is expected that

groundwater flow will be via fractures and fissures and the location of any main, laterally extensive

fractures would be expected to have a major control on flow direction.

According to the GSI website and AECOM’s knowledge of the area, there are groundwater abstraction

wells at four manufacturing facilities close to PPI and a former public water supply well, generally with Good to Excellent well yields recorded:

• Honeywell International Technologies (550 m to the north-west, two wells currently abstracting

from depths greater than 30 m bgl and yields of 185 m3/d and 75 m

yield 65.5 m3/d)

• Former Waterford Corporation Public Water Supply (PWS) Well No. 3 (300 m to the east, drilled 1968, 61 m deep, Excellent yield 545 m

3/d)

The Waterford Corporation PWS is no longer in use and the wells at Waterford Crystal and TEVA are

also believed to be no longer in operation.

It should be noted that in Ireland there is no permitting system to govern well drilling or any

requirement to register wells. Therefore, publically available well records in Ireland are not complete;

wells used for domestic and other purposes are often not recorded by the owners or authorities.

2.5 Groundwater Monitoring Well Network

The site has installed a network of groundwater monitoring wells at locations within and outside of the

site boundary. The first well installed on site was the PPI well, which was drilled in 1997 and installed

as a deep bedrock aquifer monitoring well.

In 20101, 15 shallow monitoring wells (MW1 to MW15) were drilled and installed on site; these wells

are screened within overburden subsoils (see Figure 3). Four deeper on site monitoring wells,

screened within fractured bedrock (MW16, MW17, MW19 and MW20), were installed in 20122. PPI

also installed a sixth deep monitoring well (MW18) outside the site boundary to the east-north-east in

2012.

In addition to these wells, the site routinely monitors groundwater from selected bedrock aquifer

monitoring wells installed around (301, 404 and 501), and down-gradient (504 and 505) of, the former

Honeywell Process Solutions site. The former Honeywell site is located to the north of PPI, see Figure

2. The network of monitoring wells screened within the bedrock aquifer across the industrial estate is

illustrated in Figure 4.

2.6 Groundwater Monitoring and DQRA

Analysis of groundwater from beneath and down-gradient of the site has detected several chlorinated

hydrocarbons; some of the compounds detected are related to historic solvent use on-site (TCE and

related compounds). A detailed quantitative risk assessment (DQRA) of chlorinated hydrocarbons

detected in groundwater was completed in 2013 and submitted to the EPA3.

The DQRA concluded that there was a potential risk to down-gradient abstraction wells from

chlorinated hydrocarbons detected in groundwater from beneath the PPI site (TCE and related

compounds). It was also concluded that TCE is being biodegraded in situ, leading to declining

concentration trends, i.e. TCE is being naturally attenuated in groundwater. However, it was also

concluded that there are other VOCs detected in groundwater, which are not related to historic

practices on site, and which are also compromising the resource value of groundwater in bedrock

beneath the industrial estate. Annual groundwater monitoring was recommended to include monitored

natural attenuation (MNA) parameters indicative of redox state and biodegradation.

During annual groundwater monitoring conducted in 2014, a thin (0.155 m) floating layer of separate-

phase hydrocarbon was detected on groundwater in monitoring well MW20, a deep well in the

western yard screened within bedrock. Dissolved phase fuel hydrocarbon (as total petroleum

hydrocarbon, TPH) concentrations were detected in groundwater from adjacent wells.

In June 2015, the EPA requested (EPA request for information RI003936) that PPI undertake a desk

study into the source of TPH. They further requested that groundwater, from all PPI wells and down-

gradient wells, be sampled and analysed for TPH and potential risks posed by TPH contamination assessed in accordance with the EPA’s Guidance on the Management of Contaminated Land and

Groundwater at EPA Licensed Sites (2013). This was completed in 2015 and monitoring of

groundwater from selected wells for TPH was again included in the 2016 monitoring round.

3. FIELD METHOD AND OBSERVATIONS

Field work was completed on the 19 September 2016 and 22 November 2016.

3.1 Dip Round

A dip round of depth to groundwater and total well depth measurements was completed before any

wells were purged or sampled. To assist in assessing groundwater flow direction, all known monitoring

wells in this area of the industrial estate, in addition to on- and off-site wells scheduled for monitoring,

were included in the dip round if accessible, see Tables 1 and 2.

Depth measurements were taken using an interface probe which is capable of distinguishing between

water and non-aqueous phase liquids (NAPLs). Depending on the density of NAPL relative to water, it

can be detected as either a floating layer (if less dense, e.g. fuel hydrocarbons) or as a sinking layer

(if more dense, e.g. chlorinated solvents).

While 0.155 m of floating fuel hydrocarbon NAPL had been detected in well MW20 in August 2014, in

2016 no NAPL was detected, though a hydrocarbon sheen was noted on groundwater from MW20

when sampling.

Depth to groundwater measurements were converted to corresponding groundwater elevations

relative to Ordnance Datum (OD). Well and groundwater elevations are presented in Table 2.

Groundwater elevations in the shallow monitoring well network are illustrated in Figure 5, with

elevations in the deeper bedrock illustrated in Figure 6.

Several of the shallow monitoring wells were dry, and depths to groundwater in the remainder ranged

between 0.97 m and 3.65 m below ground level (bgl). The shallow wells monitor perched groundwater

and water level elevations can vary by over 1 m within a short distance. Therefore, it is difficult to draw

groundwater contours for shallow perched groundwater illustrating the direction of groundwater flow;

hence, no groundwater contours are illustrated in Figure 5.

Depth to groundwater measurements in the bedrock aquifer on-site in September 2016 ranged

between 10.28 m and 12.95 m bgl, these correspond to elevations between 15.29 m and

18.03 m OD. Depth to groundwater measurements were within previously reported ranges.

The PPI well consistently records the lowest groundwater elevation on site, see Figure 7. Changes in

groundwater elevation in the PPI well follow a similar pattern to corresponding changes in wells

MW16 and MW17; both of which are located close by (5 m to 17 m from the PPI well). Groundwater

elevations indicate that the groundwater level in the PPI well is consistently between 2 m and 3 m

lower than in well MW16 (located 5.2 m to the south-west) and MW17 (located 16.4 m to the

northeast), see Figure 8.

Across all the bedrock wells monitored, there appears to be a step-change in groundwater elevation

between the PPI on-site wells and off-site well TBH2 (with groundwater elevations generally between

17.1 m and 19.5 m OD), and the remainder of wells located to the north and east where groundwater

elevations are much lower than at the PPI site (with groundwater elevations generally between 10.0 m

and 12.5 m OD), see Figures 6 and 9.

Given the varying bedrock groundwater elevations in the wells to the south of this step-change (i.e.

due to the PPI well groundwater elevation issue), defining groundwater contours for the bedrock

aquifer beneath the PPI site itself is problematic.

AECOM 10

To the north and east of PPI, consistent groundwater contours can be drawn (Figure 6) and indicate

that groundwater flow is to the north, then veering to the north-east. The horizontal hydraulic gradient

is estimated at ~0.02 between wells MW18 and 505.

The detection of TCE and related compounds in groundwater to the north and north-east of the PPI

site can also be used as a tracer for the direction of groundwater flow and supports the hydraulic

evidence.

3.2 Groundwater Sampling

Monitoring wells were sampled using the dedicated sampling equipment (inertial-lift tubing) which had

been previously installed in the deep wells.

Where possible, three times the volume of the standing water in each well was purged prior to

sampling. Well MW20 purged dry after 13 L (>1 well volume) had been purged; the groundwater level

was allowed to recover and MW20 was sampled on recovery. Well MW20 has purged dry during

previous monitoring rounds.

Field staff wore single-use, disposable nitrile/latex gloves during sampling which were changed

between wells to reduce the risk of cross-contamination. Samples were collected into laboratory

supplied sample containers, field filtered and preserved, where required. Samples were labelled in

the field and details recorded on a chain of custody form which accompanied the samples during

transit to the laboratory by overnight courier. On site and during transit, samples were stored in cool-

boxes chilled with frozen ice-packs.

As well 504 could not be located in September 2016, a return visit to site was required in November

2016 to sample this well. A sample from MW16 was also retaken in November 2016, as there were

some discrepancies in reported results for this well in September.

Well 301 could not be sampled on either occasion, as the well standpipe is blocked.

3.3 Water Quality Measurements

Toward the end of purging, field measurements of unstable water quality parameters were taken using

a calibrated water quality meter and, where possible, a flow-through cell to minimise contact with air.

Due to the small volume of water present in well MW20, it was not possible to take field water quality

measurements. Field measurements and observations are presented in Table 3. No water quality

measurements were recorded for well MW16 in November 2016.

pH

Groundwater pH was slightly below neutral, ranging from 6.06 (504) to 6.66 (505). pH values were

close to their long term averages. Typically, the pH range for groundwater in Ireland is 6.0 to 8.0.

Given that the bedrock is shale/slate and, therefore, low in carbonates, pH readings below 7.0 are to

be expected and are consistent with previous monitoring results at the site.

Electrical Conductivity

Electrical conductivity readings in groundwater ranged from 369 µS/cm (501) to 548 µS/cm (504).

Most electrical conductivity readings were within previously reported ranges.

The reading for well MW17 (458 µS/cm) was slightly higher than the usual range for this well

(302 µS/cm to 394 µS/cm) but still within the overall range for wells in the monitoring round.

Temperature

Temperature readings were slightly above the normal range for Irish groundwater of 10ºC to 12ºC,

ranging between 11.9oC and 15.3

oC. However, groundwater temperature is typically above 12.5

oC for

these wells, so readings for 2016 were within normal ranges for the site.

AECOM 11

Dissolved Oxygen

Dissolved oxygen readings ranged between 1.18 mg/L (PPI well) and 6.16 mg/L (MW19) in 2016. All

readings were below the concentration of 10-11 mg/L expected for fully aerated groundwater.

Dissolved oxygen in groundwater from the PPI well is usually below 2.0 mg/L and below 4.0 mg/L in

groundwater from other wells. In groundwater from wells MW18, MW19 and 501, the long term

average dissolved oxygen concentration is above 5.0 mg/L.

Redox Potential

Redox potential readings were recorded as oxidation-reduction potential (ORP) in the field and

adjusted to give Eh. Adjusted Eh readings ranged from 308 mV (MW17) to 366 (504) mV. Eh readings

indicate that groundwater varies between slightly reducing and slightly oxidising.

Both dissolved oxygen and redox potential are indicators of the reducing/oxidising state of

groundwater. Under reducing groundwater conditions TCE can be broken-down in the bedrock aquifer

through a process of reductive dechlorination. As TCE is broken-down cis-1,2-dichloroethene (cDCE)

is generated. cDCE, in turn, can be broken-down through a second reductive dechlorination step to

create vinyl chloride (VC, also called chloroethene).

3.4 Observations

A hydrocarbon sheen and odour were noted for groundwater from MW16 and MW20, both bedrock

wells are located close to the fill point for the diesel tank, see Figure 10.

Groundwater from all monitoring wells on site appeared cloudy and ranged in colour from yellow to

brown to grey. In the off-site monitoring wells, groundwater was generally cloudy and grey/brown in

colour.

4. LABORATORY ANALYSIS

4.1 Analytical Schedule

A sample inventory is presented in Table 1 detailing the monitoring wells sampled in 2016 and the

analyses scheduled. Groundwater from all of the bedrock aquifer monitoring wells sampled on-site

and off-site were scheduled for analysis of VOCs (including chlorinated hydrocarbons) and indicators

of MNA (redox and biodegradation indicators).

In addition, groundwater from selected wells on-site was analysed for TPH.

4.2 Assessment Criteria

Assessment of groundwater analytical data was completed by comparing results with published

guidelines and with criteria derived as part of the DQRA completed in 2013:

• Environmental Protection Agency (EPA) Interim Guideline Values (IGVs)

• Groundwater Threshold Values, Statutory Instrument No. 9, 2010 and No. 366, 2016 (GTVs)

• Generic Assessment Criteria protective of human health receptors in the industrial estate

(commercial GACs)

• Controlled Water Site Specific Target Levels (SSTLs)

The IGVs represent negligible groundwater contamination and were developed in 2003 using a

number of existing water quality guidelines in use in Ireland and internationally, including existing

national environmental quality standards, proposed common indicators from the groundwater

directive, drinking water standards and Geological Survey of Ireland trigger values.

GTVs were published in 2010 and updated in 2016. Exceedance of a threshold value triggers further

investigation to confirm whether the criteria for poor groundwater chemical status are being met.

AECOM 12

GACs protective of human health given the site’s industrial setting were derived; the only viable

pathway considered was vapour inhalation.

SSTLs, protective of potential groundwater users located 155 m down-gradient of the site were

derived for the site for TCE and related chlorinated hydrocarbons cDCE and VC as part of the DQRA

process in 2013. The DQRA model was revisited in 2015 in relation to fuel hydrocarbons and relevant

SSTLs were generated.

4.3 VOCs

Groundwater from five on-site and four off-site bedrock aquifer monitoring wells were analysed for

VOCs. In addition to chlorinated ethenes (TCE, cDCE and VC) a number of other VOCs are routinely

detected in groundwater from the bedrock aquifer beneath the industrial estate, specifically:

• Chlorinated methanes: trichlorofluoromethane (TCFM) and chloroform

• Chlorinated ethanes: 1,1,1-trichloroethane (TCA) and 1,1-dichloroethane (DCA)

There is a marked distinction between the composition of the VOC suite detected in groundwater from

beneath the PPI site and that detected in groundwater from down-gradient of the PPI site.

Chlorinated ethenes dominate the suite detected beneath the PPI site, while chlorinated methanes

dominate off-site, see Figure 11.

VOC results for 2016 are presented in Table 4, together with available historic results.

No VOCs were detected above laboratory method detection limits (MDLs) in groundwater from well

MW19. No VOCs have been detected in groundwater from up-gradient well MW19 since it was first

sampled in February 2012.

TCE, cDCE and VC were initially detected in groundwater from MW20, up to 207 µg/L, but have

declined, with only a trace detection of vinyl chloride reported for 2016, 0.6 µg/L. Concentration

trends for MW20 are illustrated in Figure 12.

Chlorinated ethene concentrations have also declined in groundwater from MW16. TCE was below

the MDL in 2015 and 2016, and concentrations of cDCE and VC were 13 µg/L and 6 µg/L

respectively. cDCE had been detected at 2,214 µg/L in February 2012. Concentration trends are

illustrated in Figure 13.

In groundwater from MW17 chlorinated ethene concentrations over the longterm are relatively static.

TCE was detected at 70 µg/L while cDCE was detected at 228 µg/L, see Figure 14.

The highest VOC concentrations on-site are detected in groundwater from the PPI well; detections

are again dominated by chlorinated ethenes. In 2016 TCE was detected at 187 µg/L, cDCE at

1,576 µg/L and VC at 29 µg/L. Over the long term, the general trend in concentrations is downward,

see Figure 15.

A similar pattern of detections has been seen in groundwater from off-site monitoring wells 301 and

404, with chlorinated ethenes generally detected at low concentrations or below the MDL, while TCFM

is detected at several 1,000 µg/L. In 2016, it was not possible to sample groundwater from 301. In

groundwater from 404, chlorinated ethene concentrations were less than 20 µg/L, while TCFM was

detected at 1,711 µg/L. Chlorinated ethene concentrations are illustrated in Figure 16.

Chlorinated ethenes tend to be below detection in groundwater from off-site well 501, as was the case

in 2016. TCFM tends to be detected at the highest concentration in groundwater from this well,

120 µg/L in 2016, with an historic peak of 521 µg/L (November 1998).

In the farthest off-site wells, 504 and 505, low concentrations of chlorinated ethenes are detected,

generally <20 µg/L in groundwater from 504 and <50 µg/L in groundwater from 505. Concentration

trends for 504 are illustrated in Figure 17 while they are illustrated in Figure 18 for well 505.

TCFM is also detected in groundwater from both wells, with concentrations in groundwater from well

505 tending to be above 1,000 µg/L since December 2007, in 2016 the detected concentration was

930 µg/L.

With regard to detections of chlorinated ethenes in groundwater, cDCE is typically detected at higher

concentrations than TCE. In particular, in groundwater from the PPI well, which has the highest

chlorinated ethene concentrations, cDCE is detected >1,500 µg/L, while TCE is detected at

<150 µg/L, an order of magnitude difference. The greater prevalence of cDCE indicates that there has

been significant in situ biodegradation of TCE through in-situ reductive dechlorination in the

subsurface.

None of the VOC concentrations detected in groundwater exceeded GAC protective of human health

(in terms of potential vapour intrusion and inhalation). The concentrations of TCE and cDCE in

groundwater from the PPI well and MW17 exceeded the controlled water SSTL, as did VC in

groundwater from the PPI well and MW16.

4.4 Redox and Biodegradation Indicators

Results for indicators of redox conditions and biodegradation are presented in Table 5.

Results are not indicative of strongly reducing groundwater conditions, as nitrate is detected in

groundwater from several wells. However, dissolved iron and manganese are also detected in

groundwater from some wells (MW16, MW20, 504 and 505), and are indicative of slightly reducing

conditions in groundwater from these wells. Overall, borderline anaerobic groundwater conditions are

inferred for the bedrock aquifer.

There is no marked differentiation in chloride and total alkalinity concentrations between the wells;

concentration of chloride and alkalinity would be expected to increase as TCE is biodegraded.

However, this may reflect the low TCE concentrations detected in most groundwater samples, as TCE

concentrations are generally <50 µg/L.

The higher concentrations of cDCE in certain wells confirm that TCE is being biodegraded in-situ

through reductive dechlorination.

4.5 TPH

TPH results are presented in Table 6. Aliphatic and aromatic hydrocarbons were below the MDL in

groundwater from well MW19.

In groundwater from wells MW17 and the PPI well, the only hydrocarbons detected were aliphatics in

the carbon chain length range of C6-C8, this is concluded to correspond to chlorinated hydrocarbons

detected in the VOC suite rather than fuel hydrocarbons.

It was only in groundwater from wells MW16 and MW20 that fuel related hydrocarbons were detected.

Both wells are located close to the diesel tank and fill point, see Figure 10.

The absence of fuel hydrocarbons in groundwater from the PPI well and MW17 indicates that this fuel

impact is localised to MW16 and MW20.

5. DISCUSSION AND UPDATED CONCEPTUAL SITE MODEL

5.1 5.1 Chlorinated Hydrocarbons

Source

As detailed previously in the DQRA, the source of TCE detected in groundwater relates to its historic

use as a solvent at the PPI site, i.e. pre-1991. TCE entered ground in the eastern yard, where spent

barrels of TCE were left to drain. Limited TCE was detected in shallow soil and groundwater, with the

highest concentrations detected in groundwater from the deeper bedrock, from deeper than 9.5 m bgl.

Other chlorinated hydrocarbons detected in groundwater from across the industrial estate (TCFM,

TCA, etc.) were reportedly not used at the PPI site and their sources appear to be related to known,

historic activities located outside of the PPI site boundary.

Pathways and Receptors

Workers on site are not directly exposed to TCE and related compounds in groundwater, as they have

no contact with groundwater from beneath the site. The only potential pathway that workers on site, or

on adjacent sites, could potentially be exposed to TCE and related compounds, is through

volatilisation from groundwater upwards through the vadose zone atmosphere and into the above

ground atmosphere (breathing zone). However, concentrations in groundwater are at least two orders

of magnitude lower than GACs protective of human health via this pathway; therefore, workers are not

at significant risk from this pathway.

SSTLs were derived to be protective of potential controlled waters receptors down-gradient of the site.

Groundwater from the bedrock aquifer is known to be used for industrial supply purposes in the

industrial estate, and to have previously been used for potable water supply purposes. While the

former Waterford Corporation public water supply (PWS) well, which was located 310 m from the site,

is no longer used, the DQRA considered the risk to a potential supply well located at 155 m down-

gradient of the site, i.e. half the distance from the site of the former PWS well.

In 2016, TCE and cDCE exceeded their respective SSTLs in groundwater from wells MW17 and the

PPI well, while VC exceeded its in groundwater from the PPI well and MW16. Concentrations of TCE,

cDCE and VC decline with distance from the PPI well, as illustrated in Figure 19.

Concentration data are available for the PPI well dating back to 1997, and reported concentrations of

TCE and cDCE peaked in 2002. Taking the declining concentrations from 2002 to 2016, the half-lives

of TCE and cDCE have been estimated at 4.75 years and 9.5 years, respectively, see Figure 20.

These values are consistent with those estimated in the 2013 DQRA and are comparable with the

higher end of typical TCE and cDCE half-life values from published literature sources.

Taking these half-lives and reported concentrations in the PPI well for 2016, it is estimated that it will

take ~35 years for cDCE concentrations in groundwater from the PPI well to decline to the SSTL,

while it will take TCE less than 10 years to reach the relevant SSTL (see Figure 20). These timescale

estimates are also consistent with those from the DQRA.

VC concentrations in groundwater from the PPI well are not following clear trend (see Figure 15). In

addition, VC remains below detection limits in groundwater from all wells down-gradient of the site.

As VC is a reductive breakdown product of cDCE, it will likely be detected in groundwater from

beneath the PPI site for as long as elevated cDCE is also detected.

The DQRA was conservative in calculating SSTLs that are protective of a compliance point at 155 m

down-gradient of the site, given that there is no actual supply well at this distance down-gradient of

the site, there is no known other potable groundwater user in the vicinity. The former PWS well at

310 m has not been used for many years and it is understood that there are no plans to return it to

use.

5.2 Fuel Hydrocarbons

Source

The source of fuel hydrocarbons in groundwater is related to the diesel storage tank and fill point

located between the eastern and western yards. The tank has a 2,000 L capacity and is double

skinned, it is reported by site personnel to be only a couple of years old and is situated within a bund.

Fuel in the tank powers the sprinkler pump house located in the north-western corner of the western

yard; the fuel supply is gravity fed from the tank to the pump house. Limited fuel is used for this

purpose, as the system is not in regular use, but is only tested on a weekly basis.

PPI have a second site within the industrial estate, which is located some distance to the north. The

second site has its own diesel tank, which is used to refuel PPI vehicles. Sometime prior to the August

2014 groundwater monitoring round, the refuelling system at the other site broke-down and the fuel

tank in the rear yard of the was used as a temporary backup supply for PPI vehicles.

As staff were unfamiliar with using the backup system, the refuelling point was not properly secured

following use, with a resulting loss of fuel to ground. PPI has not been able to estimate the volume of

fuel lost to ground at that time, but consider it to have been limited.

The fuel tank in the rear yard is no longer used to supply PPI vehicles, as the other refuelling system

was repaired. Improvements have also been made to the fill point, and it is now locked, reducing the

likelihood that a similar loss could occur.

Pathways and Receptors

Fuel lost to ground is interpreted to have migrated vertically downward through cracks in concrete of

the rear yard to the water table. No separate phase fuel hydrocarbons were detected when the

shallow wells were dipped in August 2014 and June 2015, indicating the fuel did not spread out

laterally. A layer of separate phase was detected in well MW20, declining from 0.155 m in August

2014 to 0.003 m in June 2015, indicating that the fuel migrated vertically downward through the

overburden to the watertable in the bedrock. In the 2016 monitoring round, no separate phase was

detected but a hydrocarbon sheen was observed on groundwater from wells MW16 and MW20.

Similarly to chlorinated hydrocarbons, workers on site are not directly exposed to fuel hydrocarbons in

groundwater, as they have no contact with groundwater from beneath the site. The only potential

pathway that workers on site, or on adjacent sites, could potentially be exposed to fuel hydrocarbons,

is through volatilisation from groundwater upwards through the vadose zone atmosphere and into the

above ground atmosphere. GACs protective of human health via this pathway were not generated, as

it is calculated that the vapour pathway would become saturated at a concentration below that at

which a potential risk could be generated.

The DQRA model from 2013 was revisited in 2015 to devise controlled water SSTLs, again taking the

compliance point as being a water supply well at a distance of 155 m down-gradient of the site. For

the majority of hydrocarbon fractions, no risk to the controlled water receptor could be generated, as

most components of diesel are not sufficiently soluble in water to impact upon ground water at a

compliance point 155 m from site, see Table 6.

It was possible to calculate SSTLs for aromatic hydrocarbons in the carbon chain length range of C10-

C12 and C12-C16, with concentrations of these ranges in groundwater from MW20 and MW16

exceeding the SSTLs. However, in groundwater from the PPI well and MW17, which are located

down-gradient and within 5 m to 22 m of wells MW16 and MW20, concentrations of all fuel-related

hydrocarbons are below detection limits.

There are elevated concentrations of some of the heavier hydrocarbon fractions (>C16 chain length

fractions) in groundwater from MW16 and MW20, which is to be expected given the observation of

hydrocarbon sheen. However, these fractions have very low solubility and mobility, and therefore will

have only very localised impact beneath the rear yard. This is confirmed by the absence of these

fractions in groundwater from the down-gradient PPI well and MW17.

6. CONCLUSIONS AND RECOMMENDATIONS

6.1 Conclusions

A groundwater monitoring round was conducted in September and November 2016 at the PPI site in

the IDA Industrial Estate, Cork Road, Waterford, with samples collected to assess concentrations of

chlorinated hydrocarbons and fuel hydrocarbons in groundwater from beneath the site and selected

off-site wells located down-gradient.

Chlorinated hydrocarbons have been detected in groundwater from beneath the PPI site since the

PPI well was installed in 1997. Some of the chlorinated hydrocarbons detected (the chlorinated

ethenes, TCE, cDCE and VC) are related to the historic use of TCE on site up to 1991. Other

hydrocarbons (TCFM, 1,1,1-TCA) detected are related to off-site sources unrelated to PPI.

Groundwater flow across the industrial estate is complex. Varying groundwater elevations over short

distances hamper determination of the groundwater flow direction in bedrock directly beneath the site.

However, beyond the northern site boundary the groundwater flow direction can be determined to be

generally to the north and north-east, with detections of chlorinated ethenes to the north and north-

east also acting as a tracer for groundwater flow from the PPI site in this direction.

Results for 2016 indicate that chlorinated ethene concentrations in groundwater from beneath the PPI

site and off-site continue to decline.

A DQRA was completed in 2013, and the conceptual site model developed remains valid. There are

no viable human health receptors exposed to chlorinated ethenes in groundwater either on site or off-

site. As a conservative measure, the DQRA considered the controlled waters receptor to be a

hypothetical water supply well located 155 m down-gradient of the site. Current concentrations in

groundwater from the PPI well, MW16 and MW17 are above SSTLs calculated to be protective of this

receptor.

Based on concentration trends in the PPI well, calculated concentration half-lives have been

estimated indicating that it will take cDCE approximately 35 years to decline to the SSTL protective of

such a water supply well, while it will take TCE less than 10 years to reach the SSTL.

While VC concentrations in groundwater from the PPI well itself do not appear to be following a

declining trend, VC remains below detection limits in all groundwater from down-gradient of the site.

The 2013 DQRA was conservative in calculating SSTLs that are protective of a compliance point at

155 m down-gradient of the site, given that there is no supply well at this distance down-gradient of

the site, there is no known other potable groundwater user in the vicinity and the former PWS well at

310 m has not been used for many years and it is understood that there are no plans to return it to

use.

In August 2014, separate phase fuel hydrocarbons were detected in deep monitoring well MW20.

The thickness of separate phase fuel hydrocarbons in MW20 has declined from the initial measured

thickness of 0.155 m in August 2014 to 0.003 m in June 2015, and only a sheen was observed in

2016.

Elevated dissolved phase fuel hydrocarbon concentrations are limited to groundwater from bedrock

wells MW20 and MW16, which are within 15 m of each other. Within a further 5 m to 22 m dissolved

phase concentrations decline below detection limits in bedrock wells and none of the shallow wells

have shown fuel hydrocarbon impacts in recent groundwater monitoring rounds.

The DQRA developed in 2013 was revisited in 2015 to derive SSTLs for various fractions of fuel

hydrocarbons. For many fuel hydrocarbon fractions no risk to the controlled water receptor could be

generated, as components of diesel are not sufficiently soluble in water to impact upon groundwater

at a compliance point 155 m from site. Therefore, while fuel hydrocarbon concentrations in

groundwater from MW16 and MW20 are elevated, the low solubility and mobility means that they

have only limited, localised impact beneath the rear yard of the PPI facility. The declining thickness of

free phase hydrocarbon detected from 2014 to 2016 suggests rapid depletion of the original

hydrocarbon source, suggesting a short term loss, as was inferred from the short term use of the

diesel tank to fuel vehicles.

6.2 Recommendations

It is recommended that groundwater monitoring continue on an annual basis. Analysis for VOC,

chlorinated ethenes, indicators of biodegradation and redox, should be undertaken on groundwater

samples from bedrock aquifer monitoring wells located on the PPI site (the PPI well and MW16,

MW17, MW19 and MW20) and off-site (wells 301, 404, 501 504 and 505), if accessible.

Given the low mobility and solubility of the fuel hydrocarbons detected, it is recommended that future

analysis of fuel hydrocarbons be limited to bedrock aquifer monitoring wells located within the rear

yard.

SOILS

DEVIATING SAMPLES

SURROGATES

DILUTIONS

NOTE

It is assumed that you have taken representative samples on site and require analysis on a representative subsample. Stones will generally be

included unless we are requested to remove them.

ISO17025 (UKAS) accreditation applies to surface water and groundwater and one other matrix which is analysis specific, any other liquids are

outside our scope of accreditation.

As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples.

Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately.

Surrogate compounds are added during the preparation process to monitor recovery of analytes. However low recovery in soils is often due to peat,

clay or other organic rich matrices. For waters this can be due to oxidants, surfactants, organic rich sediments or remediation fluids. Acceptable

limits for most organic methods are 70 - 130% and for VOCs are 50 - 150%. When surrogate recoveries are outside the performance criteria but

the associated AQC passes this is assumed to be due to matrix effect. Results are not surrogate corrected.

A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required.

If you have not already done so, please send us a purchase order if this is required by your company.

NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS

Please note we are only MCERTS accredited (UK soils only) for sand, loam and clay and any other matrix is outside our scope of accreditation.

Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40.

16/14797

WATERS

Data is only reported if the laboratory is confident that the data is a true reflection of the samples analysed. Data is only reported as accredited when

all the requirements of our Quality System have been met. In certain circumstances where all the requirements of the Quality System have not been

met, for instance if the associated AQC has failed, the reason is fully investigated and documented. The sample data is then evaluated alongside

the other quality control checks performed during analysis to determine its suitability. Following this evaluation, provided the sample results have not

been effected, the data is reported but accreditation is removed. It is a UKAS requirement for data not reported as accredited to be considered

indicative only, but this does not mean the data is not valid.

Where possible, and if requested, samples will be re-extracted and a revised report issued with accredited results. Please do not hesitate to contact

the laboratory if further details are required of the circumstances which have led to the removal of accreditation.

Where an MCERTS report has been requested, you will be notified within 48 hours of any samples that have been identified as being outside our

MCERTS scope. As validation has been performed on clay, sand and loam, only samples that are predominantly these matrices, or combinations

of them will be within our MCERTS scope. If samples are not one of a combination of the above matrices they will not be marked as MCERTS

accredited.

Negative Neutralization Potential (NP) values are obtained when the volume of NaOH (0.1N) titrated (pH 8.3) is greater than the volume of HCl (1N)

to reduce the pH of the sample to 2.0 - 2.5. Any negative NP values are corrected to 0.

Where a CEN 10:1 ZERO Headspace VOC test has been carried out, a 10:1 ratio of water to wet (as received) soil has been used.

All samples will be discarded one month after the date of reporting, unless we are instructed to the contrary.

% Asbestos in Asbestos Containing Materials (ACMs) is determined by reference to HSG 264 The Survey Guide - Appendix 2 : ACMs in buildings

listed in order of ease of fibre release.

All analysis is reported on a dry weight basis unless stated otherwise. Results are not surrogate corrected. Samples are dried at 35°C ±5°C unless

otherwise stated. Moisture content for CEN Leachate tests are dried at 105°C ±5°C.


Please note we are not a UK Drinking Water Inspectorate (DWI) Approved Laboratory .

Samples must be received in a condition appropriate to the requested analyses. All samples should be submitted to the laboratory in suitable

containers with sufficient ice packs to sustain an appropriate temperature for the requested analysis. If this is not the case you will be informed and

any test results that may be compromised highlighted on your deviating samples report.

NOTE


Please note we are not a UK Drinking Water Inspectorate (DWI) Approved Laboratory .

If you have not already done so, please send us a purchase order if this is required by your company.

Samples must be received in a condition appropriate to the requested analyses. All samples should be submitted to the laboratory in suitable

containers with sufficient ice packs to sustain an appropriate temperature for the requested analysis. If this is not the case you will be informed and

any test results that may be compromised highlighted on your deviating samples report.

ISO17025 accreditation applies to surface water and groundwater and usually one other matrix which is analysis specific, any other liquids are

outside our scope of accreditation.

As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples.

Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately.

Data is only reported if the laboratory is confident that the data is a true reflection of the samples analysed. Data is only reported as accredited when

all the requirements of our Quality System have been met. In certain circumstances where all the requirements of the Quality System have not been

met, for instance if the associated AQC has failed, the reason is fully investigated and documented. The sample data is then evaluated alongside

the other quality control checks performed during analysis to determine its suitability. Following this evaluation, provided the sample results have not

been effected, the data is reported but accreditation is removed. It is a UKAS requirement for data not reported as accredited to be considered

indicative only, but this does not mean the data is not valid.

Where possible, and if requested, samples will be re-extracted and a revised report issued with accredited results. Please do not hesitate to contact

the laboratory if further details are required of the circumstances which have led to the removal of accreditation.

Where an MCERTS report has been requested, you will be notified within 48 hours of any samples that have been identified as being outside our

MCERTS scope. As validation has been performed on clay, sand and loam, only samples that are predominantly these matrices, or combinations

of them will be within our MCERTS scope. If samples are not one of a combination of the above matrices they will not be marked as MCERTS

accredited.

Negative Neutralization Potential (NP) values are obtained when the volume of NaOH (0.1N) titrated (pH 8.3) is greater than the volume of HCl (1N)

to reduce the pH of the sample to 2.0 - 2.5. Any negative NP values are corrected to 0.

Where a CEN 10:1 ZERO Headspace VOC test has been carried out, a 10:1 ratio of water to wet (as received) soil has been used.

All samples will be discarded one month after the date of reporting, unless we are instructed to the contrary.

% Asbestos in Asbestos Containing Materials (ACMs) is determined by reference to HSG 264 The Survey Guide - Appendix 2 : ACMs in buildings

listed in order of ease of fibre release.

All analysis is reported on a dry weight basis unless stated otherwise. Results are not surrogate corrected. Samples are dried at 35°C ±5°C unless

otherwise stated. Moisture content for CEN Leachate tests are dried at 105°C ±5°C.

Surrogate compounds are added during the preparation process to monitor recovery of analytes. However low recovery in soils is often due to peat,

clay or other organic rich matrices. For waters this can be due to oxidants, surfactants, organic rich sediments or remediation fluids. Acceptable

limits for most organic methods are 70 - 130% and for VOCs are 50 - 150%. When surrogate recoveries are outside the performance criteria but

the associated AQC passes this is assumed to be due to matrix effect. Results are not surrogate corrected.

A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required.

NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS

Please note we are only MCERTS accredited (UK soils only) for sand, loam and clay and any other matrix is outside our scope of accreditation.

WATERS

Where analytes have been found in the blank, the sample will be treated in accordance with our laboratory procedure for dealing with contaminated

blanks.

It is assumed that you have taken representative samples on site and require analysis on a representative subsample. Stones will generally be

included unless we are requested to remove them.
