4 EXECUTIVE SUMMARY SNC Environment (SNC) was retained by Clare County Council to complete groundwater monitoring and sampling at the Central Waste Management Facility (CWMF) located at Ballyduffbeg, Inagh, Co. Clare. The site is a closed landfill site with an operational bring centre. Groundwater monitoring and sampling was completed at on-site and background sample locations, external to the site, to assess monthly and quarterly groundwater quality. This report covers the results of the groundwater monitoring and sampling completed in the third quarter (Q4) of 2015 (i.e., between October and December, 2015) at the CWMF. Monitoring and sampling at the CWMF took place on October 20 th, November 26 th and December 8 th, The results of the sampling programmes indicated the following: Southern Area Wells Monthly sampling completed at well BH11D, located immediately at the southwest corner of the closed landfill body, indicated that concentrations of ammoniacal nitrogen (NH4-N) were all less than the groundwater standard of mg/l ranging between the MDL of < 0.03 mg/l (October and December) and 0.05 mg/l (November). Groundwater monitoring wells BH3 and BH13 both contained NH 4-N concentrations greater than the groundwater standard of mg/l in all monitoring events between October and December. The concentrations ranged between 0.3 mg/l (BH13 October) and 0.61 mg/l (BH3 December). Two out of three monitoring events at monitoring well BH2 contained NH4 4-N concentrations slightly greater than the Groundwater Regulations in November (0.22 mg/l) and December (0.2 mg/l). Quarterly sampling at southern area monitoring well locations indicated that all wells contained TOC, TON and phenols concentrations less than the method detection limit (MDL) of 2 mg/l, 0.2mg/l and 0.1 mg/l respectively. Additionally, quarterly monitoring of inorganics and major anions indicated that all parameters (chloride, iron, potassium and sodium) were less than the 2010 Groundwater Regulations and EPA guidelines. Quarterly sampling for coliforms indicated that all southern area well locations contained total coliform concentrations greater than the EPA guideline value of 0 MPN/100ml with concentrations ranging between 16.6 MPN/100 ml (BH13) and > MPN/100ml (BH2 & BH3). One monitoring well (BH13) contained an ecoli concentration less than the EPA guideline value of 0 counts per 100ml. Monitoring wells BH2 and BH11D contained faecal coliform concentrations of 1 MPN/100ml, marginally greater than the guideline value and BH3 contained an elevated concentration of CFU/100ml for ecoli. It is considered that if the elevated NH 4-N concentrations in BH3 and BH13 were due to the migration of landfill leachate, concentrations in BH11D would be significantly higher than the concentrations found in wells located further down gradient from the waste body. The elevated concentrations are not considered to be due to leachate migration and that other potential sources of impact may exist within, or in the environs of, the site. i 3156 / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

5 Southwest Area Wells Monthly sampling indicated that monitoring wells BH4 and BH12S contained NH 4-N concentrations less than the 2010 groundwater regulation value of mg/l for all three sampling events, ranging between <0.03 mg/l (BH12S, December) and 0.12 mg/l (BH4, October). The other two southwest monitoring wells contained NH 4-N concentrations marginally greater than the 2010 Groundwater Regulation limit and ranged between 0.19 mg/l (BH12D December) and 0.36 mg/l (BH1a December). Quarterly sampling completed at these wells in November, 2015 indicated concentrations of phenols and TON less than the laboratory method detection limit (MDL). One out of four southwestern monitoring wells (BH4) contained a measurable concentration of TOC. Monitoring well BH4 contained a TOC concentration of 3 mg/l. Quarterly sampling of inorganics indicated that concentrations of chloride, iron, potassium and sodium were all below the groundwater regulations and EPA guideline values. Quarterly sampling for coliforms was completed in November, Two monitoring wells BH1a and BH4 contained total coliform concentrations above the 2010 groundwater regulations of 0 MPN/100ml with BH4 measuring saturation of > MPN/100ml. Additionally monitoring well BH4 contained e.coli concentrations slightly above the limit of 0 MPN/100ml with concentrations of 1 MPN/100ml. the other monitoring wells contained concentrations < 1 MPN/100ml. Southeast Area Wells Concentrations of NH 4-N in BH8D were greater than the 2010 groundwater standard for all sampling events with concentrations of 0.26 mg/l for October, November and December. These results are generally consistent with previous results for this monitoring well. Concentrations of NH 4-N in BH5 were lower than the 2010 groundwater standard of mg/l for all sampling events with concentrations ranging between 0.05 mg/l in December and 0.12 mg/l in October. These results were also in agreement with previous sampling events. Quarterly sampling completed in November 2015 indicated that concentrations of TOC, TON and phenols were all below the method detection limit (MDL) of the laboratory. Concentrations of inorganics were all less than the applicable groundwater standards and EPA guidelines. Quarterly sampling for coliforms was carried out in November The results indicated that monitoring well BH5 contained total coliform concentration (61.3 MPN/100ml) above the groundwater regulation value of 0 MPN/100ml. Both monitoring well locations contained E.coli concentrations below the groundwater regulation value of 0 MPN/100ml. Northwest Area Wells Sampling at monitoring wells BH14, BH15, BH6aD and BH6aS located to the northwest of the main landfill area indicated that BHs 15 and 6aS contained NH 4-N concentrations less than the 2010 Groundwater Regulations for all sample events between October and December, Monitoring well BH14 contained NH 4-N concentrations less than the 2010 Groundwater Regulation in December ( mg/l) and concentrations in October and November were greater than the 2010 Groundwater Regulation (i.e., 0.22 mg/l and 3 mg/l respectively). Samples collected from BH6aD contained NH 4-N concentrations greater than the 2010 Groundwater ii 3156 / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

6 Regulations in all three monitoring events ranging between 0.34 mg/l (October) and 0.36 mg/l (November). Quarterly and annual sampling completed at these wells in July, 2015 indicated concentrations of phenols less than the laboratory MDL in all four (4) wells, concentrations of inorganics less than the applicable groundwater standards and EPA guidelines. Quarterly monitoring of total coliforms and E.coli. Were completed in November, One (1) out of four (4) wells contained total coliform concentrations higher than the 2010 groundwater standard of 0 MPN/100ml. Monitoring well BH6as contained a total coliform concentration of 5 MPN/100ml. all four northwest monitoring wells contained e.coli concentration below the 2010 groundwater standard of 0 MPN/100ml, a slight improvement on the previous quarter. It is considered that if a persistent impact from leachate migration from the landfill existed it would be evident in all wells in this area. Therefore, the elevated NH 4-N concentrations in BH6as may be due to external factors (e.g., migration of residual fertilisers into the groundwater table). Background Wells Sampling at on-site background monitoring well BH9c indicated concentrations of NH 4-N were below the 2010 groundwater standard in October (0.16 mg/l) and December (0.17 mg/l). The concentration was higher in October (0.18 mg/l). Quarterly and sampling completed at BH9c in November, 2015 indicated concentrations of phenols and TON less than the laboratory MDL. BH9c contained a TOC concentration of 2mg/l. concentrations of inorganics less than the applicable groundwater standards and EPA guidelines. Sampling for total coliforms and faecal coliforms was completed in November, Both concentrations were lower than the 2010 groundwater regulations of 0 MPN/100ml. Monthly sampling was carried out at the four (4) off-site shallow wells (O Loughlin, Marrinan1, Marrinan 2 and McInerney). Sampling results indicated that NH 4-N concentrations in Marrinan 1 well were greater than the 2010 groundwater standard in October (1.37 mg/l).marrinan 2 well contained NH 4-N concentrations less than the 2010 Groundwater Standard in November(0.06 mg/l) and December (<0.03mg/l). Marrinan 2 exceeded the groundwater standard in October (0.24mg/l). O Loughlins and McInnerneys well contained NH 4-N concentrations less than the 2010 Groundwater Standard from October to December. Quarterly sampling at the off-site shallow wells indicated concentrations of phenols less than the laboratory MDL. All off site background wells contained concentrations of organics and inorganics below the 2010 groundwater regulations and EPA guidelines. However all four of the wells contained total coliform concentrations above the groundwater standards. One well (Marrinan 1) contained e.coli concentration above the standard of 0 MPN/100ml measuring 34.5 MPN/100ml. Quarterly sampling for total and faecal coliforms was completed in November, One well (Marrinan1) contained total coliform and e. coli less than the 2010 Groundwater Regulations of 0 MPN/100ml. The remaining wells all contained total coliform concentrations >100 MPN/100ml and e. coli concentrations ranged between 2 MPN/100ml (Marrinan2) to >100 MPN/100ml (McInerney). iii 3156 / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

INTRODUCTION SNC Environment (SNC) was retained by Clare County Council to complete groundwater monitoring and sampling at the Central Waste Management Facility (CWMF) located at Ballyduffbeg, Inagh, Co. Clare. The site is a closed landfill site with an operational bring centre. Monitoring and sampling was completed at on-site and background sample locations external to the site to assess monthly and quarterly groundwater quality. Sample locations are provided on Drawing , attached. The groundwater sampling completed in October and December, 2015 were monthly monitoring and sampling events. The sampling completed in November, 2015 was a monthly and quarterly monitoring sampling event. This report provides the results of the Fourth Quarter (Q4) sampling programme for 2015 (i.e., October to December, 2015). All sampling was completed under the appropriate health and safety regulations, including; Safety, Health and Welfare at Work Act, 2005 and the Safety, Health and Welfare at Work (General Application) Regulations, 2007 and associated Regulations. All sampling was completed with reference to Schedule E of Environmental Protection Agency (EPA) Waste Licence Ref. W (Waste Licence). Sampling frequency was completed with reference to Table E.5.5 of the Waste Licence / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

Scope of Work The following tasks were completed as part of the scope of work for the ground water sampling assessment in Q4 of 2015: Measure depth to water in each monitoring well to determine potentiometric elevation and determine purge volumes; Purge a minimum of three well volumes from each monitoring well prior to sample collection; / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

9 Monitor and record field parameters (i.e., ph, electrical conductivity and temperature) during and following purging for monthly sampling events and dissolved oxygen for quarterly sampling events. Submit monthly groundwater samples to Jones Environmental Ltd. (JEL), a UKAS accredited laboratory, in laboratory supplied sample bottles for selective analysis of ammoniacal nitrogen; Submit quarterly and annual groundwater samples to JEL in laboratory supplied sample bottles for selective analysis of the following potential contaminants of concern (PCOCs): ammoniacal nitrogen, chloride, dissolved oxygen, iron, potassium, sodium, total oxidised nitrogen, total organic carbon, phenols, total coliforms and e. coli. Prepare a quarterly report of groundwater results for Clare Co. Co Methodology SNC personnel completed three (3) groundwater sampling events at CWMF between October and December, All groundwater samples were collected in appropriate laboratory supplied sample containers and transported under chain-of custody to the JEL laboratory. SNC field personnel completed all field work with reference to section 5.6 of the EPA monitoring manual, including the following: The water level within each monitoring well was measured using a Waterline water level dip meter to determine the static water level and calculate the volume of water within each monitoring well. At least three borehole volumes of groundwater were purged from each monitoring well using dedicated waterra tubing and inertial footvalves to ensure that the samples were representative of true groundwater conditions. During purging, conductivity, ph and temperature were monitored (using a calibrated ph and conductivity meter) to determine when stabilisation had occurred. Purged water was disposed of away from the monitoring well to prevent recirculation. The observed condition of the sample and any odours from the borehole were noted as part of the field sample sheet. Dedicated sampling equipment (i.e., waterra tubing) was used for each monitoring well to avoid the risk of cross contamination. All reusable equipment (e.g., water level meters) were thoroughly cleaned after use using a non-phosphate laboratory detergent and then fully rinsed with water. Samples for chemical analysis were transferred to appropriately labelled sample containers (and preserved where required). Samples were transferred by SNC to a chilled cooler box immediately following sample collection. All samples were labelled with a unique sample identification number and transported to the contract laboratory under appropriate chain of custody documentation. All samples were stored below 4 o C prior to and during shipment / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

10 2.3. Regulatory Framework The regulatory standards used to assess groundwater water quality reflect relevant standards that are presently in place in Ireland and the European Union (EU) and are contained in the following Regulations: European Communities Environmental Objectives (Groundwater) Regulations, 2010 S.I. No. 9 of 2010; Where regulatory standards did not exist for a particular chemical parameter the analysis results were compared to EPA guidelines to assess the sample quality. The guidelines used for comparison when regulatory standards could not be applied included: Towards Setting Guideline Values for the Protection of Groundwater in Ireland - Interim Report, Environmental Protection Agency, Proposed Trigger levels Based on historic groundwater sampling results for the CWMF site Clare County Council have set proposed trigger levels for ph, conductivity, ammoniacal nitrogen and chloride in all wells included in the CWMF sampling programme. The trigger levels have been proposed as concentrations whereby a significant impact to groundwater quality has occurred and where corrective action may be required. The proposed trigger levels that have yet to be agreed with the EPA are provided in Table B.

11 3. RESULTS The analysis results tables for the groundwater samples collected at CWMF as part of the Waste Licence compliance sampling programme are provided in Appendix I and the associated laboratory reports are provided in Appendix II Field Parameters Monitoring and sampling of all groundwater wells was completed on October 20 th, November 26 th and December 8 th, The results of the site monitoring program indicated the following: The depth to groundwater (below ground surface [bgs]) at the CWMF site in October, 2015 ranged between 1.83 m (BH6aS) and m (BH11D) bgs. In November, 2015 groundwater elevation ranged between 1.90 m (BH6aS) and m (BH11D) bgs and in December, 2015 groundwater elevation ranged between 2.12 m (BH6aS) and m (BH11D) bgs; During the three (3) monitoring events completed between October and December, 2015 groundwater ph ranged between 7.1 (O Loughlin November & McInnerney October) and 8.5 (BH13 - October). Electrical conductivity levels were below the proposed trigger level of 1,500 µs/cm for all sampling events between October and December, Conductivity levels ranged between 79 µs/cm (McInnerney-December) and 1,040 µs/cm (BH15-October). Dissolved oxygen concentrations in groundwater samples collected in November, 2015 ranged between 25% saturation (BH3 & 6aS) and 73% saturation (Marrinan 1 & 2). All ph, electrical conductivity and dissolved oxygen concentrations measured during all groundwater monitoring and sampling events were within the applicable regulatory standards, EPA guidelines and proposed trigger levels included in section 2.3 of this report Ammoniacal Nitrogen Groundwater samples were collected on a monthly basis to assess concentrations of ammoniacal nitrogen (NH 4-N) in both on-site and off-site monitoring wells. The results of the analyses were compared to the European Communities Environmental Objectives (Groundwater) Regulations, 2010 S.I. No. 9 of 2010 (Groundwater Standards) and are outlined below Southern Area Wells Monitoring well BH11D is located immediately at the southwest corner of the closed landfill body with monitoring wells BH2, BH3 and BH13 located down gradient to the southwest. The analytical results for samples collected from these wells indicated the following; The NH 4-N concentrations in BH11D were less than the 2010 groundwater standard (i.e mg/l) for all monitoring events, ranging between <0.03 mg/l (October and December) and 0.05 mg/l (November) / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

12 Samples collected from on-site monitoring wells located further to the south of the main landfill body and close to the site road (i.e., BH2, BH3 and BH13) contained NH 4-N concentrations greater than the 2010 groundwater standard except in October (0.16 mg/l- BH2). BH3 indicated the highest NH 4-N concentrations between October and December, 2015 with concentrations ranging between 0.36 mg/l and 0.61 mg/l. All sample results for wells in the southern area of the site were significantly less than the proposed trigger level for NH 4-N (1.5mg/l). This is consistent with previous results. The NH 4-N concentrations found in BH11D, BH3, BH2 and BH13 are consistent with historic results for these monitoring wells. Each of the three wells BH2, BH3 and BH13 are located below ground surface and have a manhole cover to protect the well standpipes. Volumes of infiltrated surface water runoff exist in the base of each manhole that has the potential to percolate into the underlying aquifer and may affect groundwater sample quality. It is considered that if the elevated NH 4-N concentrations in BH3 and BH13 were due to the migration of landfill leachate then the concentrations in BH11D (i.e., at immediate boundary of the waste body) would be significantly higher than those in wells located further from the waste body. The elevated concentrations in down gradient wells BH3 and BH13 may be due to run off from the site roads or from fertilisers used historically in the surrounding forestry. All analytical results for NH 4-N were significantly less than the proposed trigger level of 1.5mg/l. Further sampling programmes will provide continued trends of NH 4-N concentrations at all monitoring wells to assess if the elevated NH 4-N concentrations in wells seasonally fluctuate and if the potential impacts at some wells may be due to other sources other than leachate migration (e.g., fertilisers used in forestry surrounding that site) West / Southwest Area Wells Monitoring wells BH12S, BH12D and BH4 are located to the southwest and BH1a is located west of the main landfill area; the analysis results for all wells indicated the following: The concentrations of NH 4-N in BH4 and BH12s were less than the 2010 groundwater standard for all sample events between October and December, The highest concentrations measured in these two wells was 0.12 mg/l in October (BH4). The concentrations of NH 4-N in BH1a were similar to BH12D (i.e., all monitoring events indicated concentrations greater than the 2010 Groundwater Regulations). The concentrations in BH1a and BH12D ranged between 0.19 mg/l in BH12D (December, 2015) and 0.36 mg/l in BH1a (October and December, 2015). All analysis results for NH 4-N were consistent with historic results and were significantly less than the proposed trigger level of 1.5 mg/l Southeast Area Wells Monitoring well BH8D is located immediately at the southeast corner of the closed landfill body and BH5 is located further down gradient, south from BH8D. The analysis results for both wells indicated the following: / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

13 The concentrations of NH 4-N in BH8D were marginally greater than the 2010 groundwater standard for all sampling events with concentrations measuring 0.26 mg/l for all events October to December. These results are generally consistent with previous results for this monitoring well; and The concentrations of NH 4-N in BH5 were significantly less than the 2010 Groundwater Standard for all three (3) sampling events ranging between 0.05 mg/l (December, 2015) and 0.07 mg/l (November, 2015), indicating good quality groundwater in that area. NH 4-N concentrations in BH5 and BH8D are consistent with previous analytical results. All analytical results for NH 4-N were significantly less than the proposed trigger level of 1.5 mg/l Northwest Area Wells Monitoring wells BH6aS, BH6aD, BH14 and BH15 are located to the northwest of the main landfill area. The analytical results for these wells indicated the following: Monitoring well BH15 contained NH 4-N concentrations below the MDL for all sampling events between October and December, Monitoring well BH6as also contained NH 4-N concentrations below the 2010 Groundwater Regulations, ranging between 0.03 mg/l (October) and 0.06 mg/l (November) BH14 and BH6aD contained NH 4-N concentrations greater than the 2010 groundwater for all sampling events except for December when BH14 contained a concentration of 0.03 mg/l. BH6aD contained the highest concentrations for all sampling events with concentrations ranging between 0.34 mg/l (October, 2015) and 0.36 mg/l (November, 2015). It is considered that if a persistent impact from leachate migration from the landfill existed it would be evident in all wells in this area. Therefore, the marginally elevated NH 4-N concentrations may be due to other factors. The area around the wells is heavily forested. It is a common forestry management practice to significantly fertilise newly planted areas, there may be residual migration of these fertilisers into the groundwater table in the wells indicating elevated concentrations (i.e., BH6aD). Observations of purged water from wells in the area (particularly BH14) have indicated turbid groundwater even after well redevelopment and purging has been completed. All analytical results for NH 4-N were significantly less than the proposed trigger level of 1.5 mg/l Background Wells One (1) on-site background monitoring well (BH9c) and four (4) off site wells (O Loughlin, Marinan 1 and 2 and McInerney) were sampled during the three (3) sampling events between October and December, It should be noted that the four (4) off-site wells are historical shallow groundwater wells that are open to surface infiltration and may not be fully representative of true groundwater conditions. The analytical results for these wells indicated the following; Background well BH9c indicated that concentrations of NH 4-N were below the 2010 groundwater standard in October (0.16 mg/l) and December (0.17 mg/l) and was marginally greater than the 2010 groundwater standard in November (0.18 mg/l), 2015; / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

14 Monthly sampling at the Marrinan 1 monitoring well indicated one sampling event (1.37 mg/l, October, 2015) where the NH 4-N concentration was greater than the 2010 Groundwater Regulations. The samples collected in November and December 2015 both contained concentrations of 0.05 mg/l and were significantly less than the 2010 Groundwater Regulation limit of mg/l. Monthly sampling at the Marrinan 2 monitoring well indicated one sampling event (mg/l, October, 2015) where the NH 4-N concentration was greater than the 2010 Groundwater Regulations. The samples collected in November (0.06 mg/l) and December (<0.03 mg/l) 2015 both contained concentrations significantly less than the 2010 Groundwater Regulation limit of mg/l. The monitoring well at O Loughlins contained NH 4-N concentrations less than the 2010 Groundwater Standard in all sampling events between October and December, with concentrations of 0.05 mg/l for all sample events. The monitoring well at McInnerneys contained NH 4-N concentrations less than the 2010 Groundwater Regulations for all sampling events between October and December, with concentrations ranging between 0.03 mg/l (October) and 0.07 mg/l (December). Historically water samples collected from the off-site shallow wells indicated that the concentrations of NH 4-N fluctuate in each well. Each of the four wells is located on agricultural land Organics Quarterly groundwater samples were collected from all nineteen (19) monitoring wells on November 26 th, 2015 to assess concentrations of total oxidised nitrogen and total organic carbon. The results indicated the following; One (1) out of 15 (15) on site monitoring well locations contained a detectable concentration of total oxidised nitrogen (TOC) of 0.2 mg/l. well BH4 contained a TOC concentration of 2 mg/l. The offsite monitoring wells contained TOC concentrations ranging between 2 mg/l (McInnerney,O Loughlin) and 9 mg/l (Marrinan 2). None of nineteen (19) monitoring well locations contained detectable total organic carbon (TOC) concentrations and were all less than the laboratory method detection limit (MDL) of 0.2 mg/l Inorganics Quarterly groundwater samples were collected from all 19 monitoring wells on November 26 th, 2015 and submitted for dissolved metals and major anions analysis. The results for the quarterly programme completed in November, 2015 were compared to the EPA Guideline Values for the Protection of Groundwater in Ireland Interim Report, 2003 (EPA Surface Water Guideline Values) and European communities environmental objectives (groundwater) regulations, 2010 The analysis results indicated the following: / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

15 Chloride concentrations ranged between 0.22 mg/l (BH2) and 73.1 mg/l (BH4) Iron concentrations for all off site and on site wells were below the laboratory MDL concentration of 20 µg/l. All onsite wells contained potassium concentrations below the 2010 groundwater objective regulations. All offsite wells contained elevated concentrations but only one was above the regulation value of 5 mg/l (8.2 mg/l Marrinan 1). Sodium concentrations ranged between 11.5 mg/l (Marrinan 2) and 61.5 mg/l (BH8D) and were less than the 2010 Groundwater Regulation limit of 150 mg/l. None of the on-site monitoring wells are used for drinking water abstraction and the shallow wells off-site are not used for direct abstraction for drinking water Phenols No standards are included in the 2010 Groundwater Regulations for phenols. Therefore, the results for the quarterly sampling programme completed in July, 2015 were compared to the EPA Guideline Values for the Protection of Groundwater in Ireland Interim Report, 2003 and the 2009 Surface Water Regulations as a conservative comparison. All submitted groundwater samples contained concentrations of phenols less than the laboratory method detection limit (MDL) of 0.1 mg/l and less than the EPA groundwater guideline value Microbiology Quarterly groundwater samples were collected on November 26 th, 2015 and submitted for e-coli and total coliform analysis with the results compared to the applicable groundwater quality standard. The analysis results indicated the following: Five (5) monitoring wells contained detectable e-coli concentrations that exceeded the 2010, groundwater standard of 0 MPN/100ml. these ranged between 1 MPN/100ml (BH2,BH3,BH4,BH11D) which were only marginal exceedences and 34.5 MPN/100ml (Marrinan 1). Twelve (12) of the 19 submitted samples contained concentrations of total coliforms greater than the groundwater regulations value of 0 MPN/100ml, ranging from 5 MPN/100ml (BH6aS) to > 100 MPN/100ml (BH2,BH3,BH11D,BH13,BH1a,BH4, Marrinan1 & Marrinan 2, O loughlin and McInnerney). The detectable microbial concentrations may be due to bacterial growth in the well pipes or sample tubing and is not considered to be an indication of potential impacts on ground water quality in the underlying aquifer. The microbial concentration in the background shallow wells are considered to be a result of surface water infiltration from surrounding agricultural land / January 18 th, 2016 Printed on Recycled Paper EPA Export :00:48:10

If no samples are listed it is because none were deviating. Only analyses which are accredited are recorded as deviating if set criteria are not met. QF-PM v3 Please include all sections of this report if it is reproduced 4 of 7

54 NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS JE Job No.: 15/15099 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 (UKAS) accreditation applies to surface water and groundwater and one other matrix which is analysis specific, any other liquids are outside our scope of accreditation. As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples. Where 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. 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.
