1. INTRODUCTION Land adjoining the eastern boundary of the Galway Metal Company (GMC) facility at Oranmore has been impacted by oily water run-off. The source of this run-off appears to be primarily from the GMC site but other off-site sources may have contributed to the impacts. Galway County Council (the Council) instructed GMC to undertake an investigation to establish the extent of contamination. GMC commissioned O’Callaghan Moran & Associates (OCM) to carry out the investigation in 2011 the objective of which was to quantify the volume of the impacted soils and assess the impact on groundwater quality. The findings of the investigation are outlined in the OCM Report “Delineation of Off-Site Contamination” dated June 2011. In the report OCM concluded that the hydrocarbon contamination had extended across the impacted area by a combination of overland flow and migration on the top of the water table. The nature of the subsoils beneath the site have prevented the direct discharge of hydrocarbons to the underlying aquifer, however this has occurred outside the eastern boundary, where the subsoils are thinner. OCM estimated that approximately 396 tonnes of subsoil required removal. Low levels of hydrocarbon contamination were identified in the groundwater in two of three off site monitoring wells downgradient of the area to the east of the site. This is probably due to the presence of the subsoil impeding the rate of contamination migration to the aquifer. OCM recommended a series of remediation measures to firstly stop the release of the oily water onto the lands by a combination of an interceptor trench, groundwater pump sumps and chemical treatment. A groundwater monitoring programme was to be implemented to monitor the effectiveness of the remediation works. The proposed remediation programme included;

• Installation of Cut-Off Trench along the eastern boundary of the GMC site, • Installation of Groundwater Sumps with the GMC site,

• Potential in situ treatment of the residual contamination within the GMC site,

• Potential in-situ treatment of the contamination on the lands to the east of the GMC site,

• Potential in-situ groundwater treatment,

• Monitoring to confirm the effectiveness of the programme.

2. REMEDIATION WORKS GMC has completed the remedial works programme. Since 2011 the following series of remedial tasks has been completed; Surface Pavement Repair Programme This included the opening up of cracked portions of the concrete paving, removing contaminated subsoils and sub-base materials, imported clean fill and re-sealing of the concrete paving. Eastern Boundary Cut-Off trench A cut off trench was installed along the south-eastern site boundary where oily water was observed to be discharging into the field in this area. The trench was constructed in accordance with a specification prepared by OCM and which was approved in advance by Galway County Council. Details of this programme have been included in a separate correspondences issued by GMC to Galway County Council in an initial proposal on July 27th , 2011 and in a subsequent notification of completion of the works on February 2nd 2012. Upgrade of the Surface Water Drainage System The existing surface water drainage system was inspected for leaks and where identified repairs were carried out. A new Full Retention Interceptor was installed to ensure that the final discharge complies with the facility emission limits for treated effluent. The system of inspection of and de-sludging of silt traps and oil interceptors has been modified to ensure more frequent removal of sludge and assessment of system operation. This includes for emptying of silt traps and skimming oil from interceptors on a monthly basis. Every six months all interceptors are emptied and the klargestor coalescent filters are replaced.

Western Sump During the excavation works to install the new interceptor in the southern end of the site GMC encountered minor quantities of hydrocarbon contamination in the open excavation. A concrete sump was installed in the area to remove the hydrocarbon

contamination. The sump is routinely pumped out in the event that hydrocarbons are detected on the water table. This sump which is identified as the western sump is so called because it is located to the west of the southern boundary trench described below. There is a connection between the sump and the southern trench via granular fill and a pipeline. Southern Boundary Trench Galway County Council requested that a trench be installed close to the southern site boundary. The trench was installed in May 2012 the details of its construction were included in a report submitted to the Council on July 19th 2012. The purpose of the trench was to establish if there was hydrocarbon contamination in the subsoil or groundwater migrating to the south away from the site. The trench was installed so that any hydrocarbon contamination in the trench can be intercepted and pumped out to the on site oil interceptor system. OCM understand that during the excavation of the trench no hydrocarbon contamination was encountered in the subsoil or groundwater. Eastern Sump A concrete sump was also installed at the eastern end of the southern trench to establish if hydrocarbon contamination was present in the groundwater east of the southern trench. Removal of Contaminated Soil and Subsoil and Restoration of Lands to East of GMC Facility The final element of the remediation works incorporating the removal of contaminated soil, in-situ treatment of the excavation area, reinstatement of the excavation with clean subsoil and top soil and grass seeding was completed in May 2013 and are documented in the OCM Report Remediation Works dated August 2013.

3. WATER QUALITY MONITORING PROGRAMME Following a site inspection on October 9th 2012 OCM recommended that a water quality monitoring programme should be undertaken at a number of locations to assess the effectiveness of the remediation programme to date. The monitoring locations are illustrated on Figure 1 and are described below. Monitoring was initially completed in October 2012 and subsequently in August 2013. The current report summarises the groundwater monitoring programme undertaken between August 2013 and September 2014 and a surface water monitoring programme undertaken on October 21, 2014. 3.1 Groundwater Quality Monitoring In 2012 OCM recommended that groundwater quality be monitored in up hydraulic gradient monitoring well BH-2, down hydraulic gradient monitoring well BH-3 and in the lands to the east at locations BH-4, 5 and 6. In addition OCM recommended that samples of the groundwater in the eastern cut-off drain, the western sump, the southern boundary trench and the eastern sump be collected for analysis. In 2014, the groundwater samples were collected by GMC and sent to Jones Environmental Forensics Ltd, a UKAS accredited laboratory for analyses. The analysis included Extractable Petroleum Hydrocarbons (EPH), Benzene, Toluene, Ethylbenzene and Xylene, (BTEX), MTBE, poly aromatic hydrocarbons, (PAH) dissolved heavy metals (Aluminium, Antimony, Barium, cadmium, chromium, copper, iron, lead, mercury, nickel, potassium, selenium, sodium and zinc) and a range of standard anions and cations. This range of analysis was selected to assess the potential for contamination associated with site activities and the hydrochemical composition of the groundwater.

3.2 Results The most recent set of Laboratory Results are included in full in Appendix 1 and are summarised below.

3.2.1 Groundwater

The results are presented on Tables 3.1 – 3.5. The tables include the Environmental Protection Agency Interim Guideline Values (IGVs) and the Groundwater Threshold Values (GTV) from the 2010 Groundwater Regulations (SI No. 9 of 2010). The IGVs are included as they provide a broader range of parameters for which comparative guideline values have been compiled by the Environmental Protection Agency than the groundwater regulations.

3.2.1.1 Heavy Metals Mercury was detected marginally above the GTV in the East and West Sump and in up hydraulic gradient monitoring well BH-2. The level in the East and West sump was equal to but did not exceed the IGV. Zinc marginally exceeded the IGV of 100 µg/l in the Eastern Cut-off Trench at 104 µg/l. All other parameters did not exceed their respective GTV’s or IGV’s. Table 3.1 Heavy Metals 18th September 2014 Sample ID Units BH2 BH3 BH4 BH5 BH6 GTV IGV

3.3 Assessment of Groundwater Flow Direction Groundwater levels were measured in all wells, sumps and cut off trenches on the 10th October 2014. The data is plotted as a hydraulic contour map on Figure 3.2. It should be noted that such plots are influenced by the number of available data points to generate accurate maps and as such primarily illustrate trends in flow. Only groundwater levels taken from within the boreholes are used to create the GW flow maps as these will be consistent across the site. The predominant flow is from the northwest to the south east toward both the Irish Rail Drain and the Carrowmonesh stream. This general trend of flow from northwest to southeast is as would be expected and supports the assumption that the shallow groundwater discharges to the stream.

3.4 Surface Water Sampling Programme The samples were collected on October 21, 2014 by Galway Metal Company at the following points;

• Upstream on the Carrowmonesh Stream near the N-17 Public Road

• Downstream of the confluence of the Irish Rail Field drain with the Carrowmonesh Stream which is down stream of the facility. The sample locations are indicated on Figure 3.3.

The samples were placed in laboratory prepared containers and stored in coolers to maintain sample temperature at approximately 4°C. Chain of custody (COC) documentation was completed and accompanied the samples to the Jones Environmental Forensics Ltd, a UKAS accredited laboratory. The laboratory method detection limits were below the comparative standards used for the assessment of the sediments and water samples. The samples were analysed for included Extractable Petroleum Hydrocarbons (EPH), Benzene, Toluene, Ethylbenzene and Xylene, (BTEX), MTBE, Volatile Organic Compounds and a range of standard anions and cations including Nitrate, Sulphate, Chloride and also Chemical Oxygen Demand, Total Dissolved Solids, Electrical Conductivity and pH. The full results are included in Appendix 2 and are summarised on Table 3.6. The results presented on Table 3.6, includes for comparative purposes the limits in the Surface Water Environmental Objectives (Surface Water) Regulations 2009 (SI 272 of 2009).

* - AA-EQS means that for each representative monitoring point within the water body, the arithmetic mean of the concentrations measured over a twelve month monitoring period does not exceed the standard ** - MAC-EQS means that for each representative monitoring point within the water body no measured concentration exceeds the standard. There is no evidence of an impact on the surface water quality downstream from the activities occurring at the facility. The ammonia levels are elevated up and downstream. The higher downstream levels may be as a result of wastewater treatment discharges. The site discharges to the Council foul sewer and is not therefore a source of such discharges.

4. DISCUSSION 4.1 Groundwater Quality As was the case in 2013 the majority of heavy metals are not elevated in the groundwater either beneath, or down hydraulic gradient of the facility. Mercury was detected above the GTV and IGv in BH-2. BH-2 is located up hydraulic gradient of all site activities and indicates an offsite up hydraulic gradient source for this parameter. Mercury was detected marginally above the GTV but not above the IGV in the Eastern and Western Sumps. Zinc was detected just above the IGV (100 µg/l) in the Eastern Cut-off Trench (104 µg/l). There is no GTV for Zinc. All other concentrations were either close to or below the LoD of 3 µg/l. The primary contaminants of concern are hydrocarbons.

PAH concentrations remain undetected in BH-2 and compared to 2013 PAH concentrations are no longer detected in the western sump or the southern cut off trench. Total PAHs are detected in BH-3 (21.27 µg/l), BH-4 (4.39 µg/l), BH-5 (8.96 µg/l) and BH-6 (3.3 µg/l). These exceed the GTV of 0.075 µg/l and have increased in concentration since August 2013. However, only one of the individual PAHs for which there are IGV’s or GTVs is exceeded in one monitoring location. The Fluoranthene concentration in BH-3 of 4.89 µg/l exceeds the IGV of 1 µg/l. BTEX or MTBE concentrations did not exceed the GTV or IGV limits in any monitoring location. Mineral oil and GRO were not detected in any of the monitoring locations. EPH was detected in BH-6. The C10-C40 concentration of 540 µg/l exceeded the IGV of 10 µg/l. There is no GTV for Mineral Oil, GRO or EPH. Ammonia and Potassium exceeded the IGV in BH-3, 4, 5 and 6 and in the Eastern Sump and Eastern Cut-Off Trench. Chloride was below the GTV in all locations but marginally above the IGV in BH2, 4 and in the Eastern Cut-Off Trench.

The elevated levels of Chloride, Ammoniacal Nitrogen (as N) and Potassium may be indicative of localised impact on water quality from sources such as wastewater treatment discharges. It is also possible that the agricultural use of the lands to the east of the facility contribute to the levels of these parameters found in BH-4, BH-5 and BH-6 due to agricultural use of the lands to the east of the facility. 4.2 Data Trends Comparison between 2009 -2014 Monitoring Results OCM completed a Hydrogeological Site Assessment in 2009. The report dated August 17th, 2009 was submitted to the Council at that time. As part of that assessment three groundwater wells were installed in the lands to the east of the site (BH-4, 5 and 6) and all the existing and new wells were sampled to assess the impacts on groundwater quality. The assessment identified that hydrocarbon contamination was present in BH-3 and BH-8 and to a lesser extent in BH-4, 5 and 6. The sources were considered in part to be associated with GMC and in part from the Galway Oil facility. Tables 4.1-4.4 present the data from the monitoring conducted in 2009 compared to the results from sampling events completed in 2012, 2013 and 2014. As indicated in Section 3, the heavy metals with the exception of aluminium and mercury in 2009, are all below the IGV and GTV. These concentrations have fallen to non-detectable levels between 2009 and 2014 with the exception of 1 minor detection of mercury in BH-2 (2 µg/l) in September 2014 where the IGV of 1 µg/l was exceeded. BH-2 is an up hydraulic gradient monitoring well.

No PAHs were detected in BH-2. Total PAH concentrations had declined between 2009 and 2013 but they have been detected again, at low levels, in 2014 in BH-3, 4, 5 and 6. In 2009 very elevated levels of DRO were detected in BH-3, BH-5 and BH-6 with a lesser concentration in BH-4. Since then significant remedial works have been completed at the site and with the exception of EPH in BH-6 there have been no hydrocarbon related exceedances of the IGVs. Potassium and ammonia levels have remained elevated since 2009. However, the highest levels are typically off-site in the agricultural lands to the east of the site (BH-4, BH-5 and BH-6) and may be associated with the agricultural use of these lands. 4.3 Data Trends 2009 – 2011 -2014 (GMC Monitoring Programme) GMC conducts groundwater monitoring at BH2 up hydraulic gradient and BH-3 and BH-5 down hydraulic gradient of the site for hydrocarbons, copper, lead and zinc, at quarterly intervals. The results from February 2011 to date are presented in Figures 4.1 – 4.5. The results highlight the effectiveness of the remedial measures in reducing impacts on groundwater quality beneath and down hydraulic gradient of the facility. Figures 4.1 and 4.2 show the Mineral Oil and Total Petroleum Hydrocarbons trends. Figures 4.2-4.5 show the Lead, Zinc and Copper trends respectively.

Figure 4.5 Copper

Mineral Oils had been undetected in the groundwater since August 2011. There was a significant reduction in (TPH) hydrocarbon concentrations in the down hydraulic gradient wells, BH-3 and BH-5 between June and August 2011. The reduction coincides with the implementation of the remedial works described in Section 2. There has been a slight increase in TPH in BH-3 in January 2014 but concentrations were reduced in March 2014 and were undetected again in September 2014. Figures 4.3 - 4.5 show the trends for lead, zinc and copper. The decline in concentrations of these parameters has been more gradual, but commenced earlier in 2011. Since then the concentrations of Lead and Copper have been consistently below the IGV and GTVs for these parameters and are frequently below laboratory detection limits also. Zinc is more frequently encountered but the concentrations are well below the IGV and GTVs. 4.4 Groundwater Flow Direction The general trend of flow is from northwest to southeast. The Carrowmonesh Stream flows to the east less than 30m from the southern site boundary. The shallow groundwater flow would be expected to follow this trend.

4.5 Surface Water As the groundwater beneath the site discharges to the Carrowmoneash Stream down hydraulic gradient of the facility to the southeast GMC collected samples of the surface water in October 2014 to establish if the hydrocarbons detected in the groundwater in 2014 were impacting on the surface water receptor downstream of the site. The results indicate that hydrocarbons are not detectable and consequently there are no impacts on surface water quality downstream of the facility.

5. CONCLUSIONS AND RECOMENDATIONS 5.1 Conclusions The remedial works programme has resulted in a significant improvement in the quality of the groundwater beneath and down hydraulic gradient of the facility. The general trend of groundwater flow is from northwest to southeast and the shallow groundwater discharges to the stream. While some hydrocarbons are still present in the groundwater primarily beneath the site the down hydraulic gradient of the site, groundwater quality has improved substantially since the remediation works were completed. PAHs have increased in BH-3, 4, 5 and 6 since 2013. At the same time PAH’s were not detected in sumps and trenches which were installed along eastern and southern boundaries of the Galway Metal Company site to intercept potential migration of contamination beneath the site. The shallow groundwater beneath the site discharges to the Carrwonmeash Stream downstream of the facility. Surface water quality monitoring downstream of the facility confirms that the hydrocarbons detected in the groundwater down gradient of the site are not impacting on this surface water receptor further downstream of the facility. The monitoring well network to the southeast of the facility is effective in terms of establishing the potential impact on groundwater quality emanating from the facility and in terms of ongoing monitoring of the effectiveness of the remedial works programme. 5.2 Recommendations OCM recommend that the programme of maintenance of the surface water drainage system and removal of water from the interception trenches be continued to ensure that the improvement in groundwater quality is maintained.

SOILS

DEVIATING SAMPLES

SURROGATES

DILUTIONS

NOTE

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. If we are instructed to keep samples, a

storage charge of £1 (1.5 Euros) per sample per month will be applied until we are asked to dispose of them.

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 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.

14/10752

WATERS

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.

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

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.

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.

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

% 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 Drinking Water Inspectorate (DWI) Approved Laboratory . It is important that detection limits are carefully considered

when requesting water analysis.

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.

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.
