2 INTRODUCTION

2.1 Project Contractual Basis and Personnel Involved McCarthy Keville O'Sullivan Ltd. have been reporting and monitoring groundwater on behalf of The City Bin Co. at the waste transfer site for the last twelve years. McCarthy Keville O’Sullivan Ltd are contracted to do all environmental monitoring and reporting required to comply with the transfer stations EPA Waste Licence as required under Schedule D & Schedule E of the transfer station’s EPA Waste Licence (Licence No. W0148-01). All monitoring procedures abide by EPA guidelines to avoid contamination of samples and to collect a sample that best represents the condition of the groundwater at each monitoring location. Strict procedures have been set out to ensure the safe storage and preservation of the samples prior to being received at the certified laboratory for analytical testing. The sampling work completed on a quarterly basis is conducted by Owen Cahill a qualified Environmental Engineer from McCarthy Keville O’Sullivan Ltd. Owen Cahill’s CV can be viewed in Appendix 1. He is assisted by Kate Rybczynska who is a staff member of The City Bin Company.

2.2 Background information This report outlines the methodologies, results and interpretations of the groundwater monitoring carried out at The City Bin Co. Ltd. waste transfer station at Carrowmoneash, Oranmore, County Galway during the fourth quarter of 2017 (October 1st to December 31st). This monitoring and reporting are required under Schedule D and Schedule E of the transfer station’s EPA Waste Licence (Licence No. W0148-01) in order to control emissions from the facility and provide for the protection of the environment. This report was put together with reference to the EPA document ‘Guideline Template for Groundwater Monitoring Report for the Environmental Protection Agency’.

2.3 Site Location The City Bin Co. Ltd. waste transfer station is located in the townland of Carrowmoneash, Oranmore, Co. Galway, approximately 140 metres east of the N18 (Galway – Limerick) National Primary Road, 420 metres north of the N6 (Galway – Dublin) Dual Carriageway and approximately 30 metres north of the Galway – Dublin railway line. Figure 2.1 shows the location of the site in Carrowmoneash, Oranmore, Co Galway. Other facilities surrounding the waste transfer station include the Galway Metal Company, the Galway Oil Depot Site and a property previously owned by Steelforms Ltd is now occupied by Greenway who are an international construction company. The Deerpark Industrial Estate and a number of commercial premises are located west of the waste transfer station, on the opposite the side of the N18. These neighbouring premises are shown in Figure 2.2. The site was previously run as a metal storage area as part of Galway metal. When City Bin Co. acquired the site, they removed the topsoil from the area for hazardous disposal due to contaminant potential from previous operations.

2.4 Site Operations The subject site is a waste transfer station operating in the handling and storage of commercial and domestic waste. An estimate of 60,000 tonnes per year of household, commercial, construction and demolition and industrial non-hazardous waste is authorised to

be brought on site and is temporarily stored pending removal offsite. The City Bin Co. has twelve collection trucks operating out of the waste transfer station collecting commercial and domestic waste in the Galway area. There is also a fully licensed waste and recycling drop-off area for the public located within a section of the transfer station. The site operations manager is David O’ Hanlon. David and his assistant work together to complete the main daily operations that involve weighing in and recording waste truck load deliveries, operating machinery to neatly store the waste material in the waste storage shed and receiving the public into the waste recycling drop off area. In addition to this the staff ensure the general maintenance of the site, supply and management of wheelie bins for customer delivery, general weighbridge office duties and conducting regular environmental, health and safety checks. Figure 2.3 shows the transfer station site layout. Waste trucks enter the transfer station via the security gate, are weighed on the weighbridge beside the weighbridge office and then emptied in the recycling building. The City Bin Co. collection trucks are parked over night in the parking area.

2.5 Groundwater Quality

2.5.1 Groundwater Vulnerability The vulnerability of the aquifer underlying the site is classified as predominately “Extreme” by the GSI (www.gsi.ie). In accordance with the National Bedrock Aquifer Map the aquifer is categorised as regionally important. This is mainly due to the underlying bedrock which is karstified limestone which is very permeable.

2.5.2 Groundwater Body Status The EU Water Framework Directive aims to protect, enhance and restore all waters had aimed to achieve at least good status by 2015. Local Groundwater Body status reports are available for download from www.wfdireland.ie. The transfer station lies on The Clarinbridge groundwater body (GWB). This GWB extends south to Kilcolgan and Ballinderreen, west to Oranmore Bay incorporating Clarinbridge, north to Oranmore and east to Athenry. It is classified as having ‘Poor Status’ and ‘At Risk’ from groundwater contamination. Due to its condition, a newly added EU extension requires the groundwater body to achieve ‘Good Status’ by 2021. This requires that the chemical and quantitative status of the GWB underlying the transfer station needs to be restored.

2.6 Groundwater Quality Risks

2.6.1 Potential Pollutants The transfer station does not allow for the collection of hazardous waste material. In addition, the transfer station has a concrete base and waste materials are kept dry at all times under the recycling shed. The risk of contamination to groundwater caused by activities in the transfer station are low. The following is a list of potential risks and mitigation measures in place to protect the groundwater body.

Diesel and oil leakages occurring from trucks while parked. Such substances may find their way into the groundwater via surface water runoff resulting in increased BOD, suspended solids and nutrients and or also increased DRO or PRO substances and other hydrocarbon pollutants.

Solid waste material in storage – leachate from stored waste material leaching into the groundwater resulting in increased BOD, suspended solids and nutrients in the groundwater body.

Accidental liquid waste spillage from waste trucks and entering groundwater body via

wastewater resulting in increased BOD, suspended solids and nutrients and or also increased DRO or PRO substances and other hydrocarbon pollutants.

2.6.2 Mitigation of Potential Pollutants to Groundwater There are no direct emissions to groundwater. The site is fully paved with all surface water runoff directed to a silt trap and interceptor and discharged to the surface water drainage system locally. There is no significant oil or diesel storage tanks located onsite. Vehicles are refuelled offsite. The amount of oil and diesel leakage from parked vehicles onsite is minimal and is directed to the surface water drainage system which is served by an oil interceptor. All vehicles are regularly serviced to prevent leakage and any oil or diesel from vehicles is diluted by rainwater and treated in the oil and silt interceptor. Hazardous materials are not permitted to be brought on site. If the unlikely circumstance did arise where hazardous material was brought onsite unknown to staff and caused a spillage, the staff are trained to deal with the spillage in accordance to environmental safety procedures. In all cases the use of a spill kit would be employed and the leaking item would be placed in a bunded area for containment. Again, any runoff drains into the oil and silt interceptor before being discharged from the site. All waste material is kept dry in the recycling shed. This eliminates runoff being created from the waste material in storage. In addition, the recycling shed, as with all the transfer stations, has a concrete floor to prevent any leachate seeping directly into the ground/groundwater from the stored waste.

2.6.3 Groundwater Quality Risks Summary To summarise, the site yard is completely paved and the floor of the transfer station building is concrete. Both the yard and building floor are in good condition. The domestic and commercial waste that is stored at the transfer station is non-hazardous and is stored internally. There are no significant oil or diesel storage tanks at the facility. Considering the layout of the transfer station which includes a silt and oil interceptor system, the potential for any operations onsite to cause pollution is low.

2.7 Groundwater Sampling and Monitoring All monitoring procedures put in place abide by EPA guidelines to avoid contamination of the sample. Procedures aim to collect a sample that best represents the condition of the groundwater water at each monitoring location. The procedures set out also ensure the safe storage and preservation of the samples prior to being received at the certified laboratory for analytical testing. There are six groundwater monitoring boreholes at the transfer station (GW1-GW6). These boreholes are located evenly around the site. The borehole locations can be viewed on Figure 2.3. In May 2013, the frequency of sampling was increased from bi-annually to quarterly in line with a request received from the EPA. Additional hydrocarbon parameters were also added to

the license monitoring programme. The frequency of sampling was restored to biannual sample analysis and the suite of analysis was restored to the original parameters following a request and subsequent approval by the EPA in letters received in April and June 2014 respectively. These parameters are listed in Appendix 2 alongside the laboratory methodologies used and the frequency of analysis as agreed with the agency. The following methodology is used onsite when sampling groundwater.

2.7.1 Groundwater Sampling Methodology Health and safety high visibility vest must be worn during sampling. All health and safety procedures as per Transfer Station Health and Safety statement must be followed.

Samples are collected in containers obtained from Jones Laboratories. The following

bottle types are used; 2 x Litre Green Glass, 2 x Vials

Sample locations are shown on Figure 2.3.

Pumps are stored in the plant room. Separate pumps for each groundwater monitoring borehole must be used to avoid cross contamination. The pumps used are in hole pumps that must be inserted into the borehole.

The pumps are powered by a car battery on a trolley that must be brought to each borehole

Loosen the borehole manhole cover using a trowel or screwdriver and lift carefully.

Remove the borehole cap.

Place the groundwater pump into the borehole, attach the wire and clips to the

battery and pump water from the borehole removing seven five litre buckets full of groundwater – i.e. three times the well volume calculated based on average water depth in well (75cm) x diameter of well casing (7cm)2 x pi (3.14) = 11.5litres. Continue pumping until a steady flow has been reached.

Take the sample after filling each bottle with the sample it is to contain and rinsing

three times with washings.

Replace borehole cap and close manhole carefully.

Make visual notes of the smell, colour and contents of the water. Note any visible inflows and possible pollution sources near each monitoring location.

Take photographs where necessary.

Samples collected are sealed, bubble wrapped and placed in a freezer box with ice

packs for collection for same day for return to Jones.

Chain of custody forms should be completed with each freezer box by Jones Environmental and McCarthy Keville O'Sullivan Ltd.

3 GROUNDWATER QUALITY RESULTS

McCarthy Keville O’Sullivan Ltd. carried out groundwater sampling on 29th November 2017, at the six specified locations marked on Figure 2.3. Water samples were sent to Jones Laboratories for testing of a range of parameters as required by the Licence.

3.1 Groundwater Quality Results Groundwater sampling results as recorded for each monitoring location during the fourth quarterly period are shown in Table 3.1 (see Appendix 3 for laboratory reports). Table 3.1 Results of Groundwater monitoring on 29th November 2017

3.2 Interpretation Results show elevated levels of Diesel Range Organics (DRO) and Mineral oil in borehole GW3. Elevated levels of hydrocarbons have been consistently detected in the groundwater since monitoring began in 2006 and these persist although at lower levels than previous monitoring events. The elevated parameters are not considered to be the result of licensed activities onsite.

4 SUMMARY AND RECOMMENDED WAY FORWARD

4.1 Summary and Conclusion of Results Further to an EPA request, a report detailing the trend of elevations in PRO, DRO and Mineral oil in groundwater quality was sent to the EPA in September 2008. Conclusions showed that elevations above IGV values for groundwater have occurred in groundwater monitoring locations at the waste facility since monitoring began in Q3 2006 in particular at GW2 and GW3. It is considered that the presence of the hydrocarbons is not a result of activities taking place within the transfer station grounds but from activities which occur external to the site. Elevations are also shown to be lower than usual. There is no activity onsite that could give rise to such elevations and thus can only be assumed that the pollutants come from an external source.

4.2 Recommended Way Forward Results continue to have slight elevations in DRO and mineral oil in borehole GW3. There is no evidence that these are a result of transfer station operations. It is concluded that the contamination must be caused by activities taking place external to the site. With such a low risk of contamination caused by operations on the site, it is recommended that groundwater monitoring frequency be reduced. It is recommended that annual monitoring should only be required given the nature and extent of the transfer station operations.

NOTE

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

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

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

accredited.

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

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

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

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

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

listed in order of ease of fibre release.

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

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

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

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

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

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

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

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

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.

REPORTS FROM THE SOUTH AFRICA LABORATORY

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

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

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

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

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

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

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

blanks.

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

outside our scope of accreditation.

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

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

NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS

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

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

WATERS

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

included unless we are requested to remove them.

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

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

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

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

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

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

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