1.0 INTRODUCTION

Bord na Mona Plc Kilberry Compost facility undertook groundwater sampling

and analysis of five boreholes within their facility at Kilberry, County Kildare

as per requirements of waste licence W0198-01.

This report details the methodology and results of the annual groundwater

sampling event undertaken at the compost facility on the 16th of November

2016.

2.1.

2.2 Representative Groundwater Sampling

2.2.1 Borehole Sampling

Groundwater in the well casing and in close proximity to the well is not

considered representative of the general groundwater at a given location. In

order to ensure groundwater samples extracted from the monitoring wells were

representative of the groundwater held in the subsurface strata and not water held

stagnant in the casing, it was necessary to evacuate the monitoring wells prior to

sampling.

A common procedure is to pump the well until between 2 and 5 bore volumes

have been removed (Marsh and Lloyd 1980 and Boating 1987). The purged

volumes were calculated on-site from the measured static water levels (measured

using an electronic well dipper) and the total depth of the well.

Samples were taken in 1 litre polypropylene containers (inorganics), PTFE

conditiond capped glass bottles (organic) and sterile bottles (Bacteriological) and

returned to the laboratory for immediate analysis. Sampling was in strict

accordance with recognised standard procedures.

2.3 Analysis of Groundwater Samples

All samples returned to the laboratory were stored at 5°C. Subsequent

analysis of all samples was carried out in strict accordance with recognised

standard methods. Table 2.2 below outlines the methods used.

3.0 ACCREDITED QUALITY SYSTEM

3.1 INAB Accreditation

Bord na Móna Technical Services Analytical Laboratories were awarded

INAB accreditation by the National Accreditation Board (NAB) in 1997. It

has always been the policy of the laboratories to achieve and maintain a high

standard of quality consistent with client's requirements in all aspects of the

work carried out within the laboratory.

NAB as a member of the International Laboratory Accreditation Cooperation

(ILAC) and the European Co-operation for accreditation (EA) have adopted

ISO 17025 as the new standard for its laboratory accreditation programme

since January 2002.

This new standard contains all of the requirements that testing laboratories

have to meet if they wish to demonstrate that they operate a quality system, are

technically competent, and are able to generate technically valid results. ISO

17025 incorporates all those requirements of ISO 9000 that are relevant to the

scope of testing services that are covered by the laboratory's quality system.

Thus a laboratory that complies with ISO 17025 will therefore also operate in

accordance with ISO 9000.

Bord na Móna Technical Services Analytical Laboratory successfully

transferred to ISO 17025 on 16th of November 2001.

3.2 Interlaboratory Proficiency Schemes

To ensure the accuracy of the analytical testing Bord na Móna participate in

several external proficiency schemes. The ongoing competence of the

laboratory and its staff is assessed by participation in various inter-laboratory

proficiency testing schemes, such as Aquacheck and the EPA scheme

organised for environmental laboratories throughout Ireland.

3.3 EPA Quality Control Register

Bord na Móna Technical Services Analytical Laboratories performance in the

EPA intercalibration scheme has insured its listing on the EPA’s register of

Quality Controlled Laboratories. Both accredited and non-accredited test

methods are assessed by these schemes.

3.4 Quality Control Audits

Bord na Móna Environmental Ltd. consistently strives to improve the quality

of the analytical work out in its laboratories. The laboratory has a full time

Quality Control Manager who assists in the organisation and execution of the

extensive programme of internal Quality Audits. These quality audits examine

all aspects of the laboratory’s Quality System, with particular focus on

auditing of test methods, and enable potential problems to be highlighted and

immediate corrective action to be taken.

3.5 Control Chain of Custody

As part of the Quality System in place in Bord na Móna, Environmental Ltd.,

measures are taken to ensure controlled chain of custody. An outline of the chain

of custody is given below.

5.0 COMMENTS

Bord na Mona Plc Kilberry Compost facility undertook groundwater sampling

of four boreholes within their facility at Kilberry, County Kildare as per

requirements of waste licence W0198-01 on the 16th of November 2016 to

conduct the monitoring event. Five groundwater borehole well samples were

obtained. Samples were returned to the laboratory for subsequent analysis. The

results for the analysis are presented in Table 4.1.

5.1 Groundwater Samples

Borehole (MW 1)

Ammonia @ 1.7 mg/l is considered to be elevated, however this result shows a

similar trend to previous results. The remaining results show similar trends to

previous annual monitoring results. The SVOC and Pesticide suite results are all

below the limit of detection. No E.coli and Total coliforms were detected.

Borehole (MW 2)

Ammonia @ 7.8 mg/l is consistent with the results obtained for previous years

however it exceeds the trigger level of 7.66 mg/l for this well. Trends will be

assessed following the next round of sampling in Q1 2016. The Arsenic result

of 7.99 ug/l is in excess of the threshold value of 7.5 ug/l as detailed in SI 9 of

2010 however it is below the IGV value of 10 ug/l and similar to previous

years. The remaining results show similar trends to previous annual

monitoring results. The SVOC and Pesticide suite results are all below the limit

of detection. Low levels of Total coliforms were detected which again exceeded

the trigger level of 42 cfu/100mls, additional analysis will be carried out in Q1

2017 to assess this trend. No E.coli was detected.

Borehole (MW 3)

Ammonia @ 5.4 mg/l is consistent with the results obtained throughout 2016

and for previous years. The remaining results show similar trends to previous

annual monitoring results. The SVOC and Pesticide suite results are all below

the limit of detection. No E.coli and Total coliforms were detected.

January 2017

Borehole (MW 4)

Ammonia @ 20 mg/l is the same result as recorded in Q3 2016. The remaining

results show similar trends to previous annual monitoring results. The

aluminium concentration of 191 ug/l exceeds the threshold value of 150 ug/l in

SI 9 of 2010 but is below the IGV value of 200 ug/l. The Arsenic result of 14.3

ug/l is in excess of the threshold value of 7.5 ug/l as detailed in SI 9 of 2010

however this result is similar to previous years. The calcium concentration of

267 mg/l exceeds the IGV value of 200mg/l. This level is similar to previous

years. SVOC and Pesticide suite results are all below the limit of detection. No

E.coli and Total coliforms were detected.

Borehole (MW 5)

Ammonia @ 9 mg/l shows a slight increase when compared to the Q3 2016

result of 8.7 mg/l. The remaining results show similar trends to previous

annual monitoring results. The SVOC and Pesticide suite results are all below

the limit of detection. Low levels of Total coliforms were detected at 8

cfu/100mls, this result is well below the trigger level of 1929 cfu/100mls. No

E.Coli was detected.
