6 1 INTRODUCTION 1.1 GENERAL INTRODUCTION Geosyntec Consultants Ltd. (Geosyntec) was retained by Swords Laboratories to undertake the groundwater monitoring programme for their site in Watery Lane, Swords ( the site ) during 2016 and to produce this groundwater monitoring report. This report presents the results and findings of the quarterly monitoring round completed in November 2016 (Q4) and places the results in the context of the Conceptual Site Model (CSM). This report also reviews trends in groundwater quality at the site over the past 12 months. The work was completed in accordance with Geosyntec s proposal reference dated 12 January As a result of site assessment work completed during 2011 and 2012, an improved understanding of the Conceptual Site Model (CSM) for the site was developed. This work also resulted in a substantial expansion of the groundwater monitoring well network. Following on from this work, the design of the site groundwater monitoring programme mandated under the facility s Industrial Emissions (IE) licence (register number P ) was altered with the Environmental Protection Agency s (EPA s) approval in March A network comprising 24 groundwater monitoring wells was agreed. Changes to the analytical schedule were also agreed (see below). In addition, Swords Laboratories is monitoring water quality on a quarterly basis at three groundwater collection sumps located along the northern portion of the eastern site boundary. The results from analysis of these samples are included in this report. The 2016 monitoring programme was directed by Graham Webb, who has approximately 25 years experience in contaminated land and groundwater assessment and remediation. The monitoring programme was managed by Trevor Montague, an environmental scientist based in Geosyntec s Dublin office. The groundwater samples were analysed by Jones Environmental Laboratory in Deeside, UK, a UKAS accredited laboratory. 1.2 BACKGROUND INFORMATION Site Setting The site is located in a semi-urban setting approximately 300 metres north of Swords town centre. The facility is mainly occupied by production plant and associated buildings and infrastructure. Ground surfaces are generally covered by concrete or asphalt. There are a number of small landscaped areas adjacent to the administrative buildings in the northern part of the site and in some other peripheral areas of the facility. The site layout is illustrated in Figure 1. Land uses close to the site include residential, commercial and recreational use. The site is bounded by the Ward River to the east, with an area of public parkland beyond. To the north and northwest the site it is bounded by Watery Lane with commercial GCU IE GW report Q (final)

7 properties beyond. To the west and southwest, land use is generally residential. Immediately adjacent to the site to the south there is a neighbouring industrial facility, which until recently was operated by Arch Chemicals, B.V. (Lonza). The Lonza facility closed in May 2013 and decommissioning of the facility is understood to have taken place during the second half of Ground elevations across the Swords Laboratories site range from approximately 17.7 m (south-western perimeter) to 11.6 m (north-eastern corner) above Ordnance Datum (AOD Malin Head Datum) with a moderate east and northeast topographic gradient towards the Ward River Site History The Swords Laboratories facility commenced operations in An Integrated Pollution Control (IPC) licence was first granted to Swords Laboratories by the EPA in December The current IE licence was granted by the EPA in September Geology The site is underlain by Lower Carboniferous bedrock, specifically the Malahide Limestone Formation, which in the Swords area is fine-grained, thinly to coarselybedded and cherty. Observations from bedrock cores recovered during past investigations and of outcrops of this formation within the bed of the Ward River show this unit to be thinly to medium-bedded (~ mm) with jointing, fracturing and faults. Borehole records generated from intrusive investigations at the site indicate a weathered zone of limestone at the interface with the overlying Quaternary deposits at some borehole locations. This has been observed as angular gravel and cobbles grading to thinly-bedded more competent bedrock. There was also evidence of some clay matrix within the gravel/cobble band and clayey infilling of wider bedding plane features from the unconsolidated soil and rock cores recovered during investigation of the site. The competent bedrock has closely-to-widely spaced fractures, occasional thin marly bands and locally, fault zones with breccia in a clayey and silty matrix. Rock cores and exposures in the Ward River bed indicate a shallow 10-20º bedrock dip in a northerly direction. Depth to bedrock across the site has been observed to vary between approximately 1.9 m and 5.5 m, with a typical depth to bedrock of 3 4 m. Glacial till has been observed overlying the limestone bedrock across the majority of the site. This has been described as ranging from silty clay to sandy gravel. Whilst the silty clay descriptions predominate for the majority of the site area, sandy and gravelly zones have been observed and appear to be particularly prevalent in the area to the north of the P2/P5 production building. GCU IE GW report Q (final)

8 The glacial till is typically overlain by a variable thickness of Made Ground, which is frequently composed of reworked glacial till. In the vicinity of the P2 tank farm and Solvent Recovery Unit tank farm, Made Ground has been encountered in the majority of boreholes. It typically comprises concrete or asphalt pavement underlain by layers of clayey and gravelly fill material. In the vicinity of the P2 tank farm, where the fill material extends below 2m depth, the Made Ground was observed to be predominantly granular. The base of this coarse granular fill was observed to extend to depths of up to 4.8m and locally to directly overlie bedrock Hydrogeology Groundwater is encountered in both in the shallow Made Ground/overburden and in the underlying bedrock at depths typically ranging from about 0.2m to 2m below ground level (bgl). The inferred lateral groundwater flow directions based on measured groundwater elevations are generally north-easterly, tending more easterly close to the Ward River (eastern site boundary). This general flow pattern is observed both for the overburden and the underlying limestone bedrock. The bedrock aquifer beneath the site is classified by the Geological Survey of Ireland (GSI) as Locally Important - moderately productive only in local zones. On a regional scale, groundwater is assumed to flow generally in an east-north-easterly direction towards the Broad Meadow Estuary. The weathered limestone is thought to be a significant horizon for groundwater flow where this is developed. As would be expected the granular fill and granular glacial till strata appear to be reasonably conductive for groundwater flow whereas the cohesive fill and cohesive drift deposits are indicated to have permeability one or two orders of magnitude less than the granular drift and weathered limestone respectively. Hydraulic conductivity values for the un-weathered bedrock indicate that below the weathered horizon the bedrock groundwater flux is likely to be relatively modest. The low to moderate permeability and thickness of the glacial till is likely to retard lateral contaminant migration within the shallow soils, and also retard downward movement to the limestone bedrock. However, preferential pathways may exist locally via natural gravel lenses and man-made gravel backfill material which locally extend close to, or possibly directly overlie the bedrock. There are also in-ground structures such as tank farm vaults and shallow groundwater containment barriers, which affect shallow groundwater flow in some sections of the site. The weathered bedrock horizon is considered to act as a sink for shallow groundwater discharge from the site Hydrology The Ward River lies approximately 5-10 m from the eastern site boundary and flows towards the north. The elevation of the river bed varies from 11.0 m AOD near the southern end of the site to 8.1 m AOD at the northern end. As such, the river bed is GCU IE GW report Q (final)

9 approximately three metres below the elevation of the site at its eastern boundary. Shallow groundwater has been observed seeping into the Ward River from the upper bedrock surface at around four locations adjacent to the site. As described above, there is also expected to be an element of groundwater base flow from the bedrock to the river. The Ward River has a relatively low flow and is not tidal in the vicinity of the site. Previous reports estimated an average flow rate of approximately 40,000 m 3 /day (0.5 m 3 /s) in the vicinity of the site. The confluence of the Ward River with the Broad Meadow River is approximately 1.5 km to the north/northeast of the site (at Balheary). From there, the combined river flows east into Broad Meadow Estuary and the Irish Sea Potential Pollutant Linkages Past investigations and monitoring events have identified impacts to groundwater quality by a number of organic compounds at the site, including tetrahydrofuran (THF), methyl-tert-butyl ether (MTBE), dichloromethane (DCM), BTEX compounds (benzene, toluene, ethyl benzene and xylenes) and a suite of alcohols and ketones. Prior to 2011, the primary area of potential concern in relation to the observed groundwater impact was in the vicinity of the P2 tank farm. Investigations completed by Geosyntec (at the time as Ford Consulting Group) during and found additional Potential Source Areas (PSAs) of groundwater impact in the vicinity of the P2/P5 production building (referred to as PSA4) and the former location of solvent recovery operations (referred to as PSA6). Both PSA4 and PSA6 were linked to historical operations at the site. Remedial action was found to be necessary in both PSA4 and PSA6. The primary Compounds of Potential Concern (COPCs) in these areas were DCM, MTBE (PSA4 only) and tert butyl alcohol (TBA a natural breakdown product of MTBE). The primary receptor potentially at risk of impact from COPCs in these two areas is considered to be the Ward River. The remedial criteria developed for the site have also considered impacts to deep groundwater quality in the wider area. Remedial action commenced in both PSA4 and PSA6 during March Until recently there was a multi-phase extraction (MPE) system operating in each of these two areas. Operation of the MPE remedial system at PSA6 ceased in December 2014 and at PSA4 in December 2015, both with the EPA s approval. The two systems have since been decommissioned and removed from site. A monitoring-based strategy has been in place for the P2 tank farm area since Ford Consulting Group, March 2011; Subsurface Assessment - Installation and Sampling of Additional Monitoring Wells, Swords Laboratories, Watery Lane, Swords, Co. Dublin 2 Ford Consulting Group, August 2012; Delineation Investigations and Revised Risk Assessment, Swords Laboratories, Watery Lane, Swords, Co. Dublin GCU IE GW report Q (final)

10 A further Potential Source Area identified at the site during 2011/2012 relates to previous losses from an effluent sump adjacent to the P4 production building (PSA3). The primary COPCs in PSA3 are THF and TBA. A hydraulic containment system has operated in this area since July Chloropyridine (2PCl) is also present in groundwater in some areas of the site. 2PCl has never been used or stored at the site and is thought to be migrating onto the facility from the adjacent Lonza property (located directly up-gradient of Swords Laboratories). As such, 2PCl is not considered to be a Swords Laboratories COPC. Groundwater samples and water levels are being collected from a number of agreed wells on the Swords Laboratories site on a quarterly basis. These samples and water levels are being passed to Lonza s consultants for subsequent analysis/assessment. It is understood that Lonza is reporting these results directly to the EPA. 1.3 PROJECT OBJECTIVES & SCOPE OF WORKS The objectives of the 2016 groundwater monitoring programme were to satisfy the requirements of the site s IE licence with regard to groundwater monitoring and to prepare an annual groundwater monitoring report for submission to the EPA. As indicated above the groundwater monitoring network was amended (with EPA approval) in A network comprising 24 groundwater monitoring wells was agreed with the EPA. Changes to the analytical schedule were also agreed. Groundwater quality is also monitored at three groundwater sumps located along the northern section of the eastern site boundary and the results from these monitoring points are included in this report. These three monitoring points do not form part of the IE groundwater monitoring network agreed with the EPA. The locations of the 27 monitoring points are illustrated by Figure 1. The groundwater monitoring network include shallow ( S series) wells installed into the overburden/weathered bedrock, as well as intermediate ( I series) wells and deep ( D series) wells, which are installed within the underlying bedrock. The shallow wells are generally installed to depths of up to 6m, the intermediate wells to depths of up to 12m and the deep wells to depths of up to 25m. The table below lists the monitoring well network and purpose of each well in the context of the IE groundwater monitoring network for the site. Borehole and well construction logs for these wells are included in Appendix C. GCU IE GW report Q (final)

This monitoring work seeks to assess if key COPCs in the overburden continue to be attenuated and also to assist in demonstrating improvements in groundwater quality in the bedrock related to the corrective action programme. Selected shallow, intermediate depth and deep wells are included in the monitoring well network to meet this objective. GCU IE GW report Q (final)

12 Monitoring groundwater quality down-gradient of other potential source areas (e.g. production buildings, tank farms, storage areas). Wells in these areas have been selected primarily to confirm that substances used in site processes are not impacting groundwater quality. Only shallow overburden wells have been selected for monitoring in these areas, as it is in this depth zone (specifically within granular Made Ground/glacial drift and the relatively permeable weathered layer at the top of bedrock) that any losses of substances to ground are likely to be first observed in the event of a future release. Based on the results of a risk assessment completed for the site during 2012, the primary COPCs present in groundwater at that time were dichloromethane (DCM), methyl tertbutyl ether (MTBE) and tert-butyl alcohol (TBA). There were a number of other organic compounds present in groundwater (e.g. BTEX compounds) at that time; however, these were found in the 2012 risk assessment not to pose a significant risk to sensitive receptors. The scope of works undertaken to fulfil the project objectives can be summarised as follows: The inspection, purging and sampling (using low flow sampling techniques) of the 24 wells included in the IE licence groundwater monitoring network (refer Table 1). Prior to purging, water level measurements were taken in all wells. During purging, wellhead parameters including ph, redox potential, dissolved oxygen and electrical conductivity were measured. The wells were purged, wellhead parameters recorded and samples collected using sampling tubing dedicated to each well, a battery-powered peristaltic pump, a flow-through cell and a calibrated YSI multi-meter; The collected samples were labelled and packed in cool boxes and were sent by overnight courier to the subcontracted laboratory accompanied by chain-ofcustody documentation. In all cases, the samples were received at the laboratory within the recommended holding times; Analysis of groundwater samples by the Jones Environmental Laboratory in Deeside, UK for a volatile organic compound (VOC) suite and a semi-volatile organic compound (SVOC) suite (in both cases including analysis for specific organic compounds used in site processes), an alcohols/acetates suite, nitrate, ammoniacal nitrogen, chloride, fluoride and chemical oxygen demand (COD). Preparation of this report on the main findings of the 2016 groundwater monitoring round 3. 3 Interim reports were submitted to the EPA following completion of the Q1, Q2 and Q3 IE groundwater monitoring rounds. GCU IE GW report Q (final)

13 Samples for the IE licence groundwater monitoring programme were collected on the following dates during 2016: Q1: 29 th February 2 nd March Q2: 5 th 7 th June Q3: 30 th August 5 th September Q4: 21 st 24 th November. In a small number of cases, groundwater samples could not be collected as there was an insufficient depth of water in the well. This was the case for AGW35-S in Q3, and for AGW22-S in Q1, Q2, Q3 and Q4. Shallow well AGW23-S was monitored in place of AGW22-S during RESULTS & TRENDS Results from the Q groundwater monitoring event are presented in Tables 1 4 and are discussed in the following sections of this report. Results from the Q1, Q2 and Q monitoring rounds are presented in three interim reports that were submitted to the EPA following completion of each of these monitoring events. Reference is made to data contained in these interim reports where relevant. Laboratory data for organic compounds detected in site groundwater from 2014 to 2016 inclusive is tabulated in Appendix A. Time series data for key COPCs at the site over recent years is also presented graphically in Appendix A for monitoring wells in the vicinity of PSA3, PSA4 and PSA6. It should be noted that there are varying start dates indicated on these graphs for different well/compound combinations. This is because some wells in the monitoring network have been monitored over a longer period than others, and also some compounds (including TBA) have not been monitored for as long as others. 2.1 FIELD-MEASURED PARAMETERS Measured groundwater elevations in the monitoring wells during 2016 were generally consistent with past monitoring events, with the inferred lateral groundwater flow direction being generally north-easterly, tending more easterly close to the Ward River (eastern site boundary). A piezometric contour map indicating the intermediate zone groundwater flow regime is shown in Figure 2. Note this piezometric contour map is a reproduction from the Q monitoring report (The IE licence conditions require two piezometric contour maps annually; these were prepared for the Q1 and Q monitoring rounds). GCU IE GW report Q (final)

14 Measurements of wellhead parameters from the Q4 monitoring round are presented in Table 2. Well head parameter observations for the four quarterly monitoring rounds completed during 2016 can be summarised as follows: ph readings were mostly in the range and were generally consistent over the four monitoring events. ph readings in monitoring well AGW08-S and AGW08-I were typically the lowest measured however there was an increase in ph in both these wells in Q (ph readings of and respectively). The alkaline ph observed at this location during the Q monitoring event may be attributable to the reconstruction of concrete pavement around these wells during the preceding weeks. Electrical conductivity (EC) readings were higher than the Groundwater Threshold Value (GTV 4 ) of 1,875 μs/cm in a number of wells during 2016, with the highest reading of 6,739 μs/cm recorded in well AGW22-I in Q3. EC readings in AGW22-I were in the range 5,868 µs/cm 6,739 µs/cm over the four monitoring events of EC readings exceeded the GTV in 7 wells in Q1, 12 wells in Q2, 8 wells in Q3 and 5 wells in Q4; the EC readings from each specific well typically varied between monitoring events, and the wells where the exceedances of the GTV were recorded changed from quarter to quarter. However, EC readings in wells AGW14-S, AGW22-I, AGW24-D and AGW29-S were consistently at the higher end of the range of EC readings recorded each quarter; Consistent with previous years, redox potential and dissolved oxygen readings were generally low, indicating that reduced groundwater conditions are prevalent across much of the site. Redox potential readings were generally negative, with readings as low as -386 mv recorded during Monitoring well AGW01-S is located close to the up-gradient site boundary and shallow groundwater conditions in this area are indicated to be generally oxidising with redox potential readings of up to 172 mv recorded during 2016; Dissolved oxygen (DO) readings across the site were generally in the range mg/l during Most DO readings were below 1 mg/l indicating relatively anaerobic conditions in groundwater at the site. This is consistent with the degradation of organic compounds taking place in groundwater in certain areas of the site targeted by the monitoring well network. 2.2 LABORATORY RESULTS The laboratory analytical results for the Q groundwater monitoring round are summarised in Table 3 (inorganic parameters) and Table 4 (organic compounds). The Q4 laboratory analysis certificates are included in Appendix B. 4 SI No. 9, 2010; European Communities Environmental Objectives (Groundwater) Regulations. GCU IE GW report Q (final)

15 As outlined earlier, time-series data indicating temporal trends in key COPCs in groundwater at the site are presented graphically in Appendix A Major Ions including Nitrogen Species & COD The groundwater samples were analysed for chloride, fluoride, nitrate, ammoniacal nitrogen and COD. Consistent with the results from past monitoring events, chloride concentrations were elevated in a number of wells across the site, which remained relatively stable throughout the year with some fluctuation noted in individual wells. Elevated chloride concentrations (above the GTV of mg/l) were recorded in the deep wells located close to the eastern site boundary (AGW24-D, AGW25-D and AGW35-D) with AGW24-D generally recording the highest chloride concentrations during 2016 (up to 969 mg/l). The presence of elevated chloride concentrations in groundwater in the shallow and intermediate monitoring wells at the site tends to correlate with areas where DCM has been detected historically. Previous investigations have demonstrated substantial microbial degradation of DCM in the site groundwater and this is thought to be the source of elevated chloride in groundwater at the site. By comparison, chloride concentrations in up-gradient well AGW01-S were in the range 25.3 mg/l to 48.5 mg/l during Fluoride concentrations in all of the groundwater samples analysed as part of the 2016 IE monitoring programme were below the IGV of 1 mg/l. The presence of ammoniacal nitrogen in groundwater at the site is consistent with the processes of microbially-mediated organic compound degradation described earlier where nitrate is progressively reduced to nitrite and ammoniacal nitrogen. Ammoniacal nitrogen was detected in most monitoring wells across the site during 2016, the exceptions being up-gradient wells AGW01-S (below the method detection limit in all rounds) and AGW10-S (below the GTV in all rounds). In the past, higher concentrations of ammoniacal nitrogen were typically observed in areas of the site where evidence of microbial degradation of COPCs was observed; e.g. PSA4 monitoring wells AGW08-S and AGW08-I. The highest concentration of ammoniacal nitrogen detected during 2016 was in the Q1 sample from AGW08-S at 16.9 mg/l. Relatively elevated concentrations of ammoniacal nitrogen were also reported in samples from AGW08-I, AGW14-S and AGW25-S during Nitrate concentrations were consistently highest during 2016 in up-gradient well AGW01-S (up to 10.4 mg/l in Q4 2016), and were typically below or close to the detection limit of 0.2 mg/l elsewhere across the site (in both overburden and bedrock wells). Chemical Oxygen Demand (COD) in most monitoring wells was in the range mg/l during COD in up-gradient well AGW01-S was below the limit of detection (LOD) of 7 mg/l for all four monitoring events. GCU IE GW report Q (final)

16 An increase in COD was noted in the Q sample from shallow well AGW16-S (2,260 mg/l), which is located at the northern end of the Solvent Recovery tank farm. Increases in concentrations of a number of organic compounds were also observed in this well in Q (refer to next section). The cause of the recent increases in this well is currently not clear; however, it is being investigated by site management Volatile Organic Compounds & Alcohols In previous years (pre-2013), elevated concentrations of a number of organic compounds were reported in a number of groundwater monitoring wells at the site. The number of well locations where this was the case reduced significantly during 2013, which is thought to be linked to commencement of groundwater remediation at PSA4 and PSA6, and to an extensive programme of testing and repairing process drains at the site during 2012 and The concentrations of organic compounds observed in monitoring wells during 2016 were generally consistent with the results recorded during 2014 and The results are discussed below by PSA. Graphs showing concentrations of key COPCs over time for each of the key PSAs are provided in Appendix A. PSA4 - P5 Building Area COPC concentrations in groundwater in PSA4 decreased significantly between Q1 and Q and have remained low or below detection since then, most notably with regard to DCM. DCM has not been detected in seven of the last eight quarterly monitoring rounds in key well AGW08-I (and it was below the MDL in six of the past eight monitoring rounds in AGW08-S). The marked decrease in COPC concentrations in AGW08-S and AGW08-I after the Q sampling round is considered to be linked to operation of the MPE groundwater remediation system in PSA4 from late March 2013 through to the end of Following commissioning of this system, the lateral extent of the dissolved-phase plume of COPCs extending down-gradient of the source area reduced significantly, and COPC concentrations in wells located close to the source area also declined. An elevated concentration of a number of organic compounds were detected in the Q sample collected from AGW08-S. These detections were short-lived, with the key compounds detected in the Q1 sample being below detection in the Q2, Q3 and Q samples from this well. Monitoring wells AGW25-S, I and D, and AGW35-S, I and D are located generally down gradient of PSA4 and close to the eastern site boundary. DCM was not detected in any of the samples collected from these wells during MTBE was the primary COPC detected in this area of the site during Investigation into the source of MTBE in groundwater in this area of the site is currently in progress. Concentrations of MTBE decreased in AGW25-S in 2015 however this was reversed with an increasing trend in MTBE concentration noted in this well during The MTBE concentration reported for well AGW25-S in Q (782 µg/l) was the highest for this GCU IE GW report Q (final)

17 well since monitoring began. A similar trend was also seen in well AGW25-I with increasing MTBE concentrations during the second half of 2016 (up to 230 µg/l in Q4 2016). MTBE remained at trace concentrations (< 1 µg/l) in the deep well at this location (AGW25-D) throughout At well AGW35-S, MTBE concentrations rose slightly during the year with a maximum concentration of 95.2 µg/l reported in Q MTBE concentrations in intermediate well AGW35-I were markedly higher than in the shallow well, up to 952 µg/l in Q In deep well AGW35-D, MTBE was either not detected, or it was detected at trace concentration (up to 3.5 µg/l) during TBA was intermittently detected at low-to-trace levels during 2016 in the abovementioned wells down-gradient of PSA4. The highest TBA result recorded in this area during 2016 was 47 µg/l in AGW35-I (Q3). P2 Tank Farm Area Wells monitored in the P2 tank farm area are AGW14-S, AGW16-S and AGW19-S. DCM was not detected in any of these wells in MTBE concentrations remained at a relatively low level in AGW14-S and AGW16-S throughout the year (up to 168 µg/l) and they remained at trace concentrations (<1.5 µg/l) in AGW19-S. TBA was generally detected at low-to-trace levels in the P2 tank farm area wells during In AGW14-S, TBA concentrations were relatively stable during the year (in the range µg/l). In AGW16-S, TBA concentrations were stable over the first three quarters (in the range µg/l). The TBA concentration (together with a number of other compounds) increased markedly in well AGW16-S in Q to 1,290 µg/l. TBA concentrations in AGW19-S remained below 10 µg/l during In the past (pre-2013), BTEX compounds were detected at elevated concentrations in P2 tank farm wells, notably at AGW16-S where BTEX concentrations in the mg/l range were typically observed. Concentrations of these compounds decreased significantly in 2013 and continued to decrease during In Q3 and Q total BTEX concentrations in all three wells monitored in the P2 tank farm area were less than 10 µg/l. During 2015 and up to Q3 2016, BTEX concentrations remained low in these wells fluctuating slightly in AGW16-S. In the Q4 sample from well AGW16-S, a number of organic compounds were detected including p/m xylene (2.03 mg/l), acetone (23.5 mg/l) and isopropyl alcohol (20.3 mg/l). As outlined earlier (with regard to TBA), the cause of these increases is currently not clear; however, it is being investigated by site management. PSA6 Former Solvent Recovery Operations Area Monitoring wells included in the IE licence monitoring network that are located downgradient of PSA6 are AGW22-S, I & D, and AGW24-D. There was insufficient water in AGW22-S during all four 2016 monitoring events to collect a representative sample (the GCU IE GW report Q (final)

18 groundwater elevation at this location is typically very close to the base of the well). Rather than leaving a data-gap for shallow groundwater quality in this area, a water sample was collected from nearby shallow well AGW23-S during each quarterly monitoring round in 2016 (this well is located immediately north of the solvent recovery control room). DCM was not detected in any of the quarterly groundwater samples collected from PSA6 area wells in MTBE was not detected in any of the quarterly samples collected from AGW22-D or AGW24-D, except for a trace detection of 0.3 µg/l in AGW24-D in Q MTBE was only detected at trace concentrations (< 5 µg/l) in samples from wells AGW23-S and AGW22-I during TBA was detected in the range µg/l in AGW22-I during TBA was also detected at low-to-trace concentrations in AGW22-D (up to 2 µg/l), AGW24-D (up to 13 µg/l) and AGW23-S (up to 10 µg/l) during PSA3 P4 Building/Process Drainage Sump Monitoring wells AGW21-S and AGW21-I are located down-gradient of PSA3. COPCs present in groundwater in this area have been linked to historic losses of effluent from a process drainage sump close to the P4 production building. The key COPCs observed in groundwater in the past in this area are MTBE, TBA and THF. A hydraulic containment system has been in operation in this area since July Consistent with the results, MTBE was detected at trace levels (<6 µg/l) in the groundwater samples collected from both AGW21-S and AGW21-I during TBA was detected in shallow well AGW21-S at low concentrations in the range 5 25 µg/l during 2016, well below the RBTV of 200 µg/l. In intermediate well AGW21-I, the TBA concentration reported in Q was below the RBTV however TBA concentrations increased in this well in Q2, Q3 and Q4 samples from this well (up to 367 µg/l in Q4), exceeding the RBTV of 200 µg/l. THF was not detected in AGW21-I during 2016, and it was only detected in the Q sample from AGW21-S (17 µg/l). North-eastern Area of the Site Monitoring well AGW28-S is located along the northern section of the eastern (downgradient) site boundary. Three former groundwater containment sumps (INSC, GCN and GCS) are also located along this boundary (Figure 1). The three sumps are located along the up-gradient side of a shallow groundwater containment wall/grout curtain, the extent of which is also indicated in Figure 1. DCM was not detected in any of the former containment sumps during quarterly monitoring throughout the period DCM was also not detected in well AGW28-S during GCU IE GW report Q (final)

19 Consistent with past monitoring results, MTBE was detected at low-to-trace concentrations in AGW28-S and the three former containment sumps during MTBE concentrations in well AGW28-S were in the range µg/l. A declining trend in MTBE concentration was observed in all three sump locations during 2016: In the southern-most containment sump GCS, MTBE concentrations declined from µg/l; In sump GCN, MTBE concentrations declined from 42.4 to 1.3 µg/l; In sump INSC, MTBE concentrations declined from 73.3 to 21.3 µg/l. TBA was detected at trace levels in most samples collected from well AGW28-S and the former containment sumps during 2016, the highest result being 36 µg/l in GCS in Q Diethyl ether is occasionally detected in the former containment sumps at trace concentrations. It was detected in sump samples collected in Q at concentrations in the range 2 3 µg/l. It was also detected in the Q4 sample from well AGW28-S at 17 µg/l. Other Areas Monitoring wells AGW04-S and AGW29-S are located down gradient of the P8 tank farm and the raw materials drum store, respectively, in the central/southern area of the site. DCM was not detected in either well during Trace levels of MTBE were detected in well AGW29-S during 2016, in the range µg/l. TBA was detected in the samples from this well in the range 2 48 µg/l. In well AGW04-S, trace concentrations of MTBE were detected during 2016, in the range 1 2 µg/l. TBA was also detected in this well, in the range 6-14 µg/l. Monitoring wells AGW03-S and AGW05-S are located in the central/western area of the site, down-gradient of the P3, P8 and P9 process buildings. DCM was not detected in either well during As was the case in previous years, MTBE was detected at trace levels in this area (up to 0.7 µg/l in AGW03-S, and up to 12 µg/l in AGW05-S). Although there was some fluctuation in TBA concentrations in AGW05-S during 2016, the declining trend observed over the past three years appeared to continue, the Q4 result of 67 µg/l being the lowest TBA result for this well since monitoring for this compound began in TBA was only detected in the Q2 sample from AGW03-S during 2016 at trace concentration (4 µg/l) Semi-Volatile Organic Compounds SVOC analysis was completed on samples collected from all monitoring wells in Q with wells in the vicinity of the P2 tank farm (AGW14-S, AGW16-S AGW19-S and AGW23-S) monitored for SVOCs on a quarterly basis. GCU IE GW report Q (final)

20 In Q4 2016, standard suite SVOCs were not detected in any of the samples analysed except in the sample from AGW16-S. 4-methylphenol was detected at a low concentration in this sample (73 µg/l). The Q samples were also analysed for SVOCs as tentatively identified compounds (TICs). SVOC TICs were not detected in any of the samples collected from AGW19-S or AGW23-S during The following compounds were reported as SVOC TICs in the Q4 sample collected from well AGW16-S: Hexylene glycol (528 µg/l) (R)-(-)-2-methyl-2,4-pentanediol (2,400 µg/l) 2-(2-methoxypropoxy)-1-propanol (317 µg/l) 3-(trifluoromethyl)-benzenamine (111 µg/l). This compound was also detected in the Q2 sample from this well at 103 µg/l. Octanoic acid (404 µg/l) 1-[2-(2-methoxy-1methylethoxy)-1-methylethoxy]-2-propanol (309 µg/l) 1-(2-methoxy-1-methylethoxy)-2-propanol (229 µg/l). Nonanoic acid, methyl ester (176 µg/l) n-decanoic acid (10,000 µg/l) 2-ethyl-heptanoic acid (145 µg/l) Dodecanoic acid (173 µg/l) With the exception of 3-(trifluoromethyl)-benzenamine, the above compounds were not detected as TICs in the Q1, Q2 or Q3 samples from AGW16-S. Further, these compounds were not detected in any of the shallow or intermediate depth wells located down-gradient of this area in Q As such, the detections of SVOCs in the Q4 sample from AGW16-S appear to be localised. 2-Chloropyridine was detected as an SVOC TIC in the Q sample from monitoring well AGW14-S at a concentration of 147 µg/l. 2-Chloropyridine has been detected in well AGW14-S in past monitoring rounds at similar concentrations. The source of 2-chloropyridine in this well is thought to be located within the adjacent Lonza site (generally south of the Swords Laboratories site). 3 SUMMARY, CONCLUSIONS AND RECOMMENDATIONS A marked decline in COPC concentrations was noted in two key areas of the site during 2013, namely the P2 tank farm area, where elevated xylenes and ethyl benzene in the mg/l range were present in the past ( ), and the PSA4 source area (AGW08-S and AGW08-I) where DCM in the g/l range was observed during GCU IE GW report Q (final)

21 With regard to the P2 tank farm area, the improvement in groundwater quality observed in Q (which has been sustained throughout the period ) is thought to be the result of repairs and upgrades made to the process drainage system in this area of the site at the time. Removal during 2012 of contaminated soil from the footprint of the new Cryogenic Unit, which is located immediately up-gradient of AGW16-S, may also have been a contributory factor. There was an increase in concentrations of a number of organic compounds in well AGW16-S in Q4 2016; these compounds were generally not observed in wells down-gradient of this location. The source of the recent detections in well AGW16-S is currently not clear; however, it is being investigated by site management. With regard to the PSA4 source area, the marked decrease in COPC concentrations in AGW08-S and AGW08-I after the Q sampling round (by several orders of magnitude) is thought to be linked to commissioning of the MPE groundwater remediation system in late March Following commissioning of this system, the lateral extent of the dissolved-phase plume of COPCs extending down-gradient of the source area reduced significantly, and COPC concentrations in wells close to the source area also reduced markedly. MTBE concentrations remained relatively stable in most of the wells monitored downgradient of PSAs in 2016 and it is now detected at low-to-trace levels in these wells (typically <100 µg/l). However, an increasing trend in MTBE concentration was noted in wells AGW25-S and AGW25-I during 2016 and concentrations in AGW35-I remained elevated. Investigation into the source of MTBE in groundwater in this area of the site is currently in progress. TBA is a breakdown product of MTBE and is present in groundwater in some areas of the site, mostly at relatively low concentrations (<0.1 mg/l). Groundwater is in a reduced state across much of the site, with low redox potential and low DO concentrations. In PSA3, PSA4 and PSA6 there is evidence that in-situ biodegradation of COPCs is occurring, with relatively elevated concentrations of ammonia and little or no nitrate present in groundwater. Chloride concentrations were generally stable in key wells during A key source of chloride ions in groundwater at the site is the natural attenuation of chlorinated solvents (primarily DCM) in groundwater. The revised groundwater monitoring programme adopted in Q is considered to be achieving the primary aims of the programme, and it is recommended that the programme continue across the same well network and with the same analytical schedule during oooooo GCU IE GW report Q (final)

71 NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS JE Job No.: 16/17700 SOILS 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 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. 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 samples will be discarded one month after the date of reporting, unless we are instructed to the contrary. If you have not already done so, please send us a purchase order if this is required by your company. Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately. 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. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. 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. % 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. 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 Any negative NP values are corrected to 0. WATERS Please note we are not a UK Drinking Water Inspectorate (DWI) Approved Laboratory. 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 Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. DEVIATING SAMPLES 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. SURROGATES 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 % and for VOCs are %. 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. DILUTIONS A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required. BLANKS Where analytes have been found in the blank, the sample will be treated in accordance with our laboratory procedure for dealing with contaminated blanks. NOTE 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.
