AECOM 1

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 June 2018 at the IDA Industrial Estate, Cork

Road Waterford (the site). This report has been prepared in accordance with AECOM proposal

reference PR-289971-ACM-PL-EN-001 dated 20 March 2018; and authorised by PPI under purchase

order number NM 016748.

The AECOM team for 2018 comprised the following:

Project Director: Kevin Forde

Project Manager: Edel O’Hannelly

Project Staff: Brendan McCarthy and Daniel O’Leary

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

The laboratory certificate is attached in Appendix C.

1.2 Background

The site 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 requested1 that groundwater from wells on-site and off-site down-gradient

wells, be sampled and analysed for fuel hydrocarbons. This was completed in 2015. Sampling of

groundwater from selected on-site wells for fuel hydrocarbons has also been included in subsequent

monitoring rounds, including the 2018 groundwater monitoring ground.

This report presents results for the annual groundwater monitoring undertaken in 2018.

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 2018 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

2018:

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 Appendix A Figure 1, and

land use 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.

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

Estate is presented in Appendix A 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 250 m north-east of PPI and flows from north-west to south-east.

The stream flows into the St. John’s River approximately 400 m 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 2.6 km north east 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 2.7 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 maps2, 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:

Former Waterford Corporation Public Water Supply (PWS) Well No. 3 (300 m to the east, drilled

1968, 61 m deep, Excellent yield 545 m3/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 20103, 15 shallow monitoring wells (MW1 to MW15) were drilled and installed on site; these wells

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

wells, screened within fractured bedrock (MW16, MW17, MW19 and MW20), were installed in 20124.

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 Schivo

Group site (former Honeywell Process Solutions site). The Schivo Precision site is located to the north

of PPI, see Appendix A Figure 2.

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

illustrated in Appendix A 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 EPA5.

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.

AECOM 4

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

phase hydrocarbons were detected on groundwater in monitoring well MW20, a deep well in the

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

hydrocarbon, TPH) 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 has been included in subsequent monitoring rounds,

including the 2018 monitoring round.

3. Field Method and Observations

Field work was completed on 18 June 2018.

3.1 Dip Round

A dip round of depth to groundwater and total well depth measurements was completed on 18 June

2018 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 Appendix B 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).

No floating or sinking NAPL layers were detected during the dip round. However, LNAPL droplets

were noted in wells MW16 and MW20 during purging.

Depth to groundwater measurements were converted to corresponding groundwater elevations

relative to Ordnance Datum (OD). Well and groundwater elevations are presented in Appendix B

Table 2. Groundwater elevations in the shallow monitoring well network are illustrated in Appendix A

Figure 5, with elevations in the deeper bedrock illustrated in Appendix A Figure 6.

Depths to groundwater in the shallow wells ranged between 1.623 m (MW7) and 3.860 m bgl (MW8).

The shallow wells monitor perched groundwater and water level elevations can vary by over 1 m

within a short distance. Groundwater contours for shallow perched groundwater illustrating the

direction of groundwater flow are illustrated in Appendix A Figure 5.

Depth to groundwater measurements in the bedrock aquifer on-site in June 2018 ranged between

9.295 m bgl (MW16) and 12.151 m bgl (PPI Well), these correspond to elevations between 28.233

(PPI Well) and 19.010 m OD (MW16). Depth to groundwater measurements were within previously

reported ranges.

The PPI well consistently records the lowest groundwater elevation in bedrock on the PPI site, see

Appendix Figures 6 and 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 north-east), see Appendix A 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 22.8 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 Appendix A Figures 6 and 9.

AECOM 5

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.

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

and indicate that groundwater flow is to the north, then veering to the north-east. The horizontal

hydraulic gradient is estimated at ~0.018 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 32 L (>2 x 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 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 and ice.

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 presence of NAPL droplets in purge water from MW16 and MW20, no field water quality

measurements were recorded for these wells. Field measurements and observations are presented in

Appendix B Table 3.

pH

Groundwater pH was close to neutral, ranging from 6.3 (501) to 6.7 (504). pH values were generally

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 for the site.

Electrical Conductivity

Electrical conductivity readings in groundwater ranged from 309 μS/cm (501) to 431 μS/cm (504).

Most electrical conductivity readings were within previously reported ranges.

Temperature

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

between 15.0 oC (504) and 18.4

oC (404). Groundwater temperatures are generally higher than

readings from June 2017. High temperatures could be attributed to the high ambient temperature on

the day of sampling6.

Dissolved Oxygen

Dissolved oxygen readings ranged between 2.36 mg/L (PPI well) and 4.98 mg/L (MW19) in 2018. All

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

AECOM 6

Dissolved oxygen in groundwater from the PPI well is usually below 2.0 mg/L and below 5.0 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 271 mV (504) to 391 (505) 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). VC can be broken-down through a third

step to create the gas ethene.

3.4 Observations

No floating or sinking NAPL layers were detected during the dip round. However LNAPL droplets were

noted in groundwater from wells MW16 and MW20 during purging.

A hydrocarbon odour was also noted from groundwater from MW16 and MW20, both bedrock wells

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

Groundwater from most on-site monitoring wells appeared turbid/cloudy and brown in colour.

Groundwater from wells MW19 and the PPI well was clear.

Groundwater from most of the off-site monitoring wells was generally clear; however, groundwater

from well 501 was cloudy and brown in colour.

4. Laboratory Analysis

4.1 Analytical Schedule

A sample inventory is presented in Appendix B Table 1 detailing the monitoring wells sampled in 2018

and 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:

EPA Interim Guideline Values (IGVs)

Groundwater Threshold Values, Statutory Instrument 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.

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

additional 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 Appendix A Figure 11.

VOC results for 2018 are presented in Appendix B 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 at a combined concentration of

up to 207 g/L in February 2012, but have since declined, with only a trace detection of VC reported

for 2018, 0.7 g/L. Concentration trends for MW20 are illustrated in Appendix A Figure 12.

Chlorinated ethene concentrations have also declined in groundwater from MW16. TCE was not

detected above the MDL (3 g/L) since 2014, and concentrations of cDCE and VC were 5 g/L and

3.1 g/L in 2018 respectively. cDCE had been detected at 2,214 g/L in February 2012.

Concentration trends are illustrated in Appendix A Figure 13. Trace concentrations of other organics

were also detected in groundwater from MW16 in June 2018, including naphthalene, o-xylene and

sec-butylbenzene, these are considered likely to be related to the presence of fuel hydrocarbons. The

total VOC concentration in groundwater from well MW16 was 19 g/L, the lowest concentration on

record for this well.

In groundwater from MW17, chlorinated ethene concentrations have been relatively static over the

long-term; concentration trends are illustrated in Appendix A Figure 14. In June 2018, TCE was

detected at 9 g/L while cDCE was detected at 16 g/L, marking reductions from 63 g/L and 93 g/L

respectively in 2017.

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

are again dominated by chlorinated ethenes. In 2018, TCE was detected at 79 g/L, cDCE at

802 g/L (10 times the TCE concentrations in this well) and VC at 27 g/L. Over the long term, the

general trend in concentrations is downward, see Appendix A Figure 15, with the concentration of

cDCE consistently higher than that of the parent compound TCE.

The pattern of detections seen in groundwater from off-site monitoring wells 301 and 404 has been

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

TCFM was typically detected at several 1,000 g/L prior to 2016. Since 2015 it has not been possible

to sample groundwater from well 301, as the well is blocked. In groundwater from 404, chlorinated

ethene concentrations were less than 10 g/L in June 2018, while TCFM was detected at 1,209 g/L.

The trends in chlorinated ethene concentrations are illustrated in Appendix A Figure 16.

Chlorinated ethenes tend to be close to, or below, detection in groundwater from off-site well 501, as

was the case in 2018. TCFM tends to be detected at the highest concentration in groundwater from

this well, 104 g/L in 2018, with an historic peak of 631g/L (January 1999).

AECOM 8

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

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

trends for 504 are illustrated in Appendix A Figure 17 and in Appendix A Figure 18 for well 505. In

2017 the total chlorinated ethene concentration in groundwater from well 504 increased to 54 g/L,

but declined again in 2018 to 23 g/L. In groundwater from 505, the concentration of chlorinated

ethenes has dropped for the third year in a row, from 47 g/L in 2017 to 40 g/L in 2018.

TCFM is also detected in groundwater from both wells. The TCFM concentration in groundwater from

well 505 tended to be above 1,000 g/L between December 2007 and June 2015. The concentration

of TCFM in groundwater from well 505 was 359 g/L in June 2018, the lowest TCFM concentration for

this well since December 2006.

In groundwater from well 504, the concentration of TCFM also increased in 2017, up to 732 g/L,

having been below 100 g/L since 2008. Similarly to chlorinated ethane concentrations in

groundwater from this well, the TCFM concentration also declined again in 2018, down to 49 g/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 at 802 g/L, while TCE is detected at

79 g/L, an order of magnitude difference. The greater prevalence of cDCE indicates that there has

been significant in situ biodegradation of TCE through reductive dechlorination in the aquifer.

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

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

groundwater from the PPI well 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 Appendix B Table 5.

Results are generally 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 MW16 and MW20 in excess of the IGV (0.2 mg/L for iron, 0.05 mg/L for

manganese), and are indicative of more reducing conditions in groundwater from these wells. It is

considered that the presence of fuel hydrocarbons in groundwater in the vicinity of wells MW16 and

MW20 is leading to the creation of more reducing groundwater conditions there.

There is generally 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.

Chloride was generally detected at a concentration between 17 mg/L (MW17) and 28 mg/L (MW20

and 505). The only exception is MW19, where chloride was detected at a concentration of 43 mg/L.

MW19 is located up hydraulic gradient of the site.

Total alkalinity was detected at concentrations between 130 mg/L (501) and 288 (MW16).

The low TCE concentrations detected in most groundwater samples, generally <50 g/L, may be

insufficient to result in changes to the background levels of biodegradation indicators. 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 Appendix B Table 6. Aliphatic and aromatic hydrocarbons were below

the MDL in groundwater from well MW19.

In groundwater from well MW17, the only hydrocarbons detected were aliphatics in the carbon chain

length range of C5-C6, this is concluded to correspond to chlorinated hydrocarbons detected in the

VOC suite rather than fuel hydrocarbons.

AECOM 9

In groundwater from wells MW16, MW20 and the PPI Well, fuel related hydrocarbons were detected.

Both MW16 and MW20 are located close to the diesel tank and fill point and the PPI well is located

approximately 5 m down gradient of MW20, see Appendix A Figure 10.

The absence of fuel hydrocarbons in groundwater from MW17 and the relatively low TPH

concentration at the PPI well (8,144 g/L compared to 500,994 g/L at MW16 and 194,557 g/L at

MW20) indicates that this fuel impact is localised to MW16 and MW20.

5. Discussion and Updated Conceptual Site Model

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 2018, TCE exceeded the SSTL in groundwater from the PPI well, cDCE exceeded the SSTL in

groundwater from the PPI well and VC exceeded its in groundwater from the PPI well and well MW16.

Concentrations of TCE, cDCE and VC decline with distance from the PPI well, as illustrated in

Appendix A 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 in the PPI well from 2002 to

2018, the half-lives of TCE and cDCE have been estimated at 4.75 years and 6.3 years, respectively,

see Appendix A 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 2018, it is estimated that it will

take ~17 years for cDCE concentrations in groundwater from the PPI well to decline to the SSTL,

while it will take TCE less than five years to reach the relevant SSTL (see Appendix A Figure 20).

VC concentrations in groundwater from the PPI well are not following a clear trend (see Appendix A

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.

AECOM 10

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

down-gradient of the site, intended to be protective of the former Waterford City Council public supply

well, 310 m from the PPI well. Given that there is no longer an actual supply well at this distance

down-gradient of the site, and there is no known other potable groundwater user in the vicinity, the

SSTL is considered appropriately conservative.

The former PWS well at 310 m has not been used for many years and it is understood from Waterford

City Council 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 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 site 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 floating LNAPL was detected in the deeper bedrock well MW20 in

August 2014, June 2016 and again in June 2017; indicating that the fuel migrated vertically downward

through the overburden to the water table in the bedrock.

The increase in NAPL thickness between September 2016 (0 mm) and June 2017 (204 mm) is

inferred to be caused by changes in water level releasing trapped hydrocarbons from the 2014 diesel

spill and not to indicate a new source. The hydrocarbon bailed from the well in June 2017 appeared

old and weathered.

In 2018, no free phase hydrocarbon layers were detected during the dip round however, LNAPL

globules were noted during purging of 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 Appendix B Table 6.

It was possible to calculate SSTLs for individual aromatic and aliphatic carbon chain lengths,

exceedances of these SSTLs were noted at wells MW16, MW20 and PPI Well. However, in

groundwater from well MW17, which is located down-gradient within 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. 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 hydrocarbon fractions in groundwater from the down-gradient well

MW17.

6. Conclusions and Recommendations

6.1 Conclusions

A groundwater monitoring round was conducted in June 2018 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 from 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 relatively low 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 2018 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 17 years to decline to the SSTL protective of

such a water supply well, while it will take TCE less than five 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 wells 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

a distance of 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 and

have been detected intermittently in subsequent monitoring rounds.

Elevated dissolved phase fuel hydrocarbon concentrations in 2018 are limited to groundwater from

bedrock wells MW16, MW20 and PPI well. Within 22 m down-gradient of these wells dissolved phase

concentrations decline below detection limits in bedrock wells and no fuel hydrocarbon impacts have

been identified in shallow monitoring wells 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 permeability of the bedrock around MW20

and the low solubility and mobility of the fuel hydrocarbon fractions present means that they have only

limited, localised impact beneath the rear yard of the PPI facility.

6.2 Recommendations

It is recommended that groundwater monitoring continue on an annual basis but with the future scope

reduced to focus on the on-site wells only.

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).

A dip round of all accessible monitoring wells within the industrial estate can be completed but,

given the low concentrations of chlorinated ethenes in groundwater from off-site wells, it is

considered that they no longer need to be included in the monitoring round.

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

analysis of fuel hydrocarbons continue to be limited to bedrock aquifer monitoring wells located

within the rear yard.

NOTE

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.

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

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

REPORTS FROM THE SOUTH AFRICA LABORATORY

Any method number not prefixed with SA has been undertaken in our UK laboratory unless reported as subcontracted.

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

The calculation of Pyrite content assumes that all oxidisable sulphides present in the sample are pyrite. This may not be the case. The calculation

may be an overesitimate when other sulphides such as Barite (Barium Sulphate) are present.

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

blanks.

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.

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.

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.

18/9702

WATERS

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.

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.
