Executive Summary
1. Murphy Environmental (a division of Murphy Concrete Manufacturing Ltd.)
operates a restoration and recovery facility for inert waste at its site (a sand and gravel pit) at Gormanston, Sarsfieldstown, Co. Meath, under EPA Licence W0151-01. Restoring the site will serve to return it in line with pre-quarrying conditions and integrate it into the surrounding landscape.
2. Quarterly monitoring of groundwater was carried out by Patel Tonra Ltd on the 28th November 2019 (Quarter 4, 2019) as required under Waste Licence W0151-01.
3. There were exceedances of the Groundwater Regulations threshold values as follows:
Ammonical Nitrogen exceeded the Groundwater Regulations in MW-1, MW-3,
MW-4, and TW-2.
4. There were exceedances of the EPA Trigger Levels in groundwater measured as follows:
Chloride exceeded the EPA trigger level in MW-14.
Sulphate exceeded the EPA trigger level in MW-19.
Conductivity exceeded the EPA trigger level in MW-20 and MW-21.
5. As these exceedances are caused by natural sources either due to agricultural activity or the geological conditions of the site and not due to site activities, they are not deemed to be incidents reportable to the Agency.

1.0 Introduction
1.1 Background 1.1.1 Murphy Environmental (a division of Murphy Concrete Manufacturing Ltd.)
operates a restoration and recovery facility for inert waste at its site (a sand and gravel pit) at Gormanston, Sarsfieldstown, Co. Meath, under EPA Licence W0151-01. Restoring the site will serve to return it in line with pre-quarrying conditions and integrate it into the surrounding landscape.
1.1.2 The facility is licensed by the Environmental Protection Agency (EPA) and operates
under Waste Licence W0151-01. The licensee (Murphy Environmental) must manage and operate the facility to ensure that the activities do not cause environmental pollution.
1.1.3 Murphy Environmental is required to carry out monitoring of surface water,
groundwater and leachate in accordance with Schedule D of Waste Licence W0151-01 (and subsequent agreements with the Agency in terms of the monitoring schedule). Quarterly sampling and analysis of groundwater for the parameters listed in Table D.6.1 of the licence were required during this sampling round, Quarter 3 of 2019.

1.3 Sampling Personnel 1.3.1 Sampling was carried out by Kerstie Flanagan (BSc (Hons), MSc, MCIWM) and
Luke Martin (BA(Hons), MSc) of Patel Tonra Ltd. on the 28th November 2019 under the instruction of Murphy Environmental.
1.4 Sampling Methodology 1.4.1 During sampling it was borne in mind that stagnant groundwater in the well casing
and in close proximity to the borehole is not representative of the general groundwater at any given location. To ensure that the groundwater samples extracted from the monitoring boreholes were representative of the water held in the underlying subterranean strata and not stagnant water held in the borehole casing, the evacuation of the borehole was undertaken before sampling was carried out.
1.4.2 Hand balers were used to obtain water samples from each borehole. The balers
were flushed after each borehole was sampled, to eliminate the possibility of cross-contamination.
1.4.3 Conductivity, pH, DO and temperature were measured in situ. Please find attached
field monitoring results in Appendix 1. The meter was calibrated before use; please see the calibration records in Appendix 4.
1.4.4 All groundwater and leachate samples were returned to the laboratory and
appropriately stored at 4oC according to standard sampling techniques. 1.5 Laboratory Details 1.5.1 Analysis of water samples was conducted by Element Materials Technology.
Element Materials Technology are UKAS accredited. Chain of Custody documentation is included in Appendix 2. Laboratory results are included in Appendix 3.
1.6 Interpretation of Results 1.6.1 Interpretative reports have been prepared and reviewed in accordance with Patel
Tonra Ltd. quality control procedures. 1.6.2 Groundwater analytical results were compared against European Communities
Environmental Objectives (Groundwater)(Amendment) Regulations, 2016 (S.I. No. 366 of 2016)1, (referred to as the ‘Groundwater Regulations 2016’).
1.6.3 EPA Parameters of Water Quality – Interpretation and Standards (2001) was
referenced throughout the interpretation (however it was noted that additional/amended legislation may now be in force).
1.6.4 Where results exceeded limits prescribed in legislation or trigger levels, this is
highlighted in the report and possible causes described. Where results exceed the EPA trigger level for Waste Licence W0151-01 they are highlighted in yellow, where they exceed the legislative limit values, they are highlighted in red.
1.6.5 A groundwater flow map has been prepared based on Q3, 2013 data. Please find
attached as Figure 2.

1.7 Site Activities 1.7.1 To aid in interpretation of monitoring reports, the type and level of activity
operating2 during the period is detailed below. 1.7.2 The W0151-01 licensed tonnes per annum is 750,000; this equates to a licensed
tonnes per month of 62,500. The level of activity on site has been banded as follows: Normal level of activity: Waste acceptance of 45,000 - 65,000 tonnes per
month
High level of activity: Waste acceptance of >65,000 tonnes per month
Low level of activity: Waste acceptance <45,000 tonnes per month
1.7.3 On this basis, the level of activity at the site for the monitoring period can be
categorised as follows:
September 2019: Low level of activity
October 2019: Low level of activity
November 2019: Site Closed
1.7.4 Gravel processing activities commenced at the site in May 2017.

3.0 Discussion
3.1 Trigger Levels 3.1.1 The results of the groundwater monitoring programme at Gormanston for Quarter 3, 2019
were compared against European Communities Environmental Objectives (Groundwater)(Amendment) Regulations, 2016 (S.I. No. 366 of 2016)22, (referred to as the ‘Groundwater Regulations 2016’) and trigger levels as specified by the EPA for this site.
3.1.2 There were exceedances of the Groundwater Regulations threshold values as follows:
Ammonical Nitrogen exceeded the Groundwater Regulations in MW-1, MW-3, MW-4, and TW-2.
3.1.3 There were exceedances of the EPA Trigger Levels in groundwater measured as follows:
Chloride exceeded the EPA trigger level in MW-14.
Sulphate exceeded the EPA trigger level in MW-19.
Conductivity exceeded the EPA trigger level in MW-20 and MW-21.
3.2 Groundwater Boreholes
Ammoniacal Nitrogen 3.2.1 Ammoniacal Nitrogen is generally present in natural waters, though in very small
amounts, as a result of microbiological activity, which causes the reduction of nitrogen-containing compounds. When present in levels above 0.1 mg/l N, sewage or industrial contamination may be indicated.
3.2.2 There were exceedances of the Groundwater Regulations threshold values for Ammoniacal
Nitrogen (0.18 mg/l N) in MW-1, MW-3, MW-4, and TW-2. 3.2.3 The Ammoniacal Nitrogen for MW-1 for Q4, 2019 (6.31mg/l) was greater than the
average result (0.41 mg/l) shown in the historical monitoring record for this location
3.2.4 The Ammoniacal Nitrogen for MW-3 for Q4, 2019 (2.32 mg/l) was greater than the average result (0.42 mg/l) shown in the historical monitoring record for this location.
3.2.5 The Ammoniacal Nitrogen for MW-4 for Q4, 2019 (0.54 mg/l) was greater than the
average result (0.74 mg/l) shown in the historical monitoring record for this location. 3.2.6 The Ammoniacal Nitrogen for TW-2 for Q4, 2019 (13.25 mg/l) was higher than the
average historical monitoring record for this location (3.02mg/l). The monitoring record shows a gradual increase in Ammoniacal Nitrogen levels at this location.
3.2.7 Ammoniacal Nitrogen has been consistently found in previous sampling rounds at various
positions on or close to the site; both upstream and downstream (see Table 3.1). This is likely to be associated with agricultural and sewage pollution sources in the area.

Chloride
3.2.7 Chloride exists in all natural waters and has no direct health or sanitary significance. 3.2.8 Chloride exceeded the EPA trigger level (70 mg/l) in MW-14 (189.6 mg/l). This is above
the historic average (56.0 mg/l) at this location. Sulphate
3.2.9 Sulphates exist in nearly all natural waters, the concentrations varying according to the nature of the terrain through which they flow. They are often derived from the sulphides of heavy metals (iron, nickel, copper and lead).
3.2.10 Sulphate exceeded the EPA trigger level (140 mg/l) in MW-19 (151.3mg/l). This is above the historic average (137.2 mg/l) at this location. Conductivity
3.2.11 Conductivity reflects the mineral salt content of water. It has no direct health/sanitary significance.
3.2.12 Conductivity exceeded the EPA trigger level (1.0mS/cm) in MW-20 (1.04mS/cm). This is
above the historic average (0.94mS/cm) at this location. 3.2.13 Conductivity exceeded the EPA trigger level (1.0mS/cm) in MW-21 (1.06mS/cm). This is
above the historic average (0.62mS/cm) at this location.

4.0 Conclusion
4.0.1 There were exceedances of Groundwater Regulations threshold values in
groundwater measured as follows:
Ammonical Nitrogen exceeded the Groundwater Regulations in MW-1, MW-3, MW-4, and TW-2.
4.0.2 There were exceedances of the EPA Trigger Levels in groundwater measured as
follows:
Chloride exceeded the EPA trigger level in MW-14, MW-21 and MW-22.
Sulphate exceeded the EPA trigger level in MW-19.
Conductivity exceeded the EPA trigger level in MW-20 and MW-21.
4.0.3 As these exceedances are caused by natural sources either due to agricultural activity or the geological conditions of the site and not due to site activities, they are not deemed to be incidents reportable to the Agency.
4.0.4 Routine ongoing monitoring will be completed in line with requirements of EPA Waste Licence W0151-01.

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.
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.
All samples should be submitted to the laboratory in suitable containers with sufficient ice packs to sustain an appropriate temperature for the
requested analysis. The temperature of sample receipt is recorded on the confirmation schedules in order that the client can make an informed
decision as to whether testing should still be undertaken.
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.
Where analytes have been found in the blank, the sample will be treated in accordance with our laboratory procedure for dealing with contaminated
blanks.
Sufficient amount of sample must be received to carry out the testing specified. Where an insufficient amount of sample has been received the
testing may not meet the requirements of our accredited methods, as such accreditation may be removed.
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.
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.
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.
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. Limits of detection for analyses carried out on as received samples are not
moisture content corrected. 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

19/19717
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.
