    EXECUTIVE SUMMARY

    Bord na Mna Waste Management are required to conduct biological monitoring on an annual basis at

    the Drehid facility in accordance with Waste Licence Register No.W0201-03. BNM Environmental was

    commissioned to perform the sampling and analysis. The site was subsequently visited by a BNM

    Environmental Scientist on the 4th of September 2016 to undertake the assessment.

    Sampling was undertaken on the Cushaling River, downstream of the Drehid facility. The biological

    quality of the stream was deemed a Q3-4 indicating slightly polluted waters.

    As the Cushaling River rises on-site, no upstream location is available from which to obtain a sample

    and assign a Q-value.

    No deterioration in biological quality was noted since the previous monitoring in September 2015.

    This report is certified as accurate and representative of the sampling and associated analysis carried

    out.

    1. INTRODUCTION

    Bord na Mna Waste Management are required to conduct biological monitoring on an annual basis

    at the Drehid facility in accordance with Waste Licence Register No.W0201-03. BNM Environmental

    was commissioned to perform the sampling and analysis.

    An Environmental Scientist from BNM Environmental visited the site on the 4th of September 2016 to

    undertake a macroinvertebrate survey to determine the Q Index of the stream.

    This report details the methodologies involved in the study and an interpretation of these findings.

    2. SAMPLING LOCATION

    The most ideal point to obtain a biological sample was deemed to be located 3km west of the

    Drehid Facility on the Cushaling River. As the river rises on the Drehid site there is no sampling

    point upstream of the facility for analysis. The river is not part of the EPAs National Biological

    Monitoring Programme.

    Figure 1 below shows the sampling point (SW1) and the Landfill Infrastructure.

    3. METHODOLOGY

    3.1 BIOLOGICAL SAMPLING

    The macroinvertebrate sample was taken in accordance with I.S. EN ISO 5667-3:2004: Water

    Quality Sampling Part 3: Guidance on the Preservation and Handling of Water Samples and

    ISO 7828: Water Quality Methods of biological sampling Guidance on Handnet sampling of

    aquatic benthic macro-invertebrates. A two minute kick sample was taken with stone washing and

    the sample was preserved in 70% ethanol. The sample was subsequently analysed following the

    EPAs Q-Value methodology (Toner et al., 2005).

    All samples are held in the laboratory for 6 months after the issue of the report.

    Habitat, as structured by in-stream and surrounding topographical features, is a major determinant

    of aquatic community quality. Both the quality and quantity of available habitat affect the structure

    and composition of resident biological communities. As such, on site habitat characteristics were

    recorded and referenced to results obtained from the sample.

    3.2 BIOLOGICAL QUALITY RATING (Q-RATING)

    This is a Pollution Rating Index, which has been developed to measure the response of certain

    key macroinvertebrate species or groups to pollution. The Q-Rating system has been

    implemented by the Environmental Protection Agency in Ireland as the standard means to

    assess the quality of any part of a stream based principally on the composition of

    macroinvertebrate communities/faunal groups present and their general sensitivity to organic

    pollution. The Biological Quality Rating forms part of S.I No. 258 of 1998, an amendment to

    the Local Government (Water Pollution) Act, 1977. The rating system recognises five

    macroinvertebrate groups ranging from A to E (i.e. most sensitive to most tolerant) and relates

    their relative abundance, from a standard 2 minute sample, to a quality rating known as a Q

    Index. The part of the stream or river surveyed may subsequently be assigned a Q rating from

    5 to 1 (i.e. pristine, unpolluted to grossly polluted). Table 3.1 presents Part I of the First

    Schedule of S.I No. 258 of 1998 which groups the macroinvertebrate indicator groups. Table

    3.2 presents Part II of the First Schedule of S.I No. 258 of 1998, which relates the Biological Q

    Rating and the five faunal groups. Table 3.3 quantifies the various abundance categories.
