3. Groundwater Groundwater samples at Monitoring Points GWI (A), GW2 (B) and GW3 (C) were taken by Fitz Scientific on the Znd March 2020. Tables 1, 2 and 3 details the results of the analysis. These results represent a biannual round of monitoring for parameters as per Table D.4. I.
4. Conclusions and Interpretation of Analysis
The results from monitoring of groundwater locations were compared to the European Communities Environmental Objectives (Groundwater) Regulations.

Reference to the relevant geological information for this area, the 1 : 100,000 scale Sheet 13 - Bedrock Geological Map of Meath (GSI 1999) indicate that this is quite a varied area of bedrock geology and one of the few areas of Permo-Triassic rocks within Ireland. A sequence of red sandstones and evaporate deposits of gypsum and anhydrite unconformably overlie a sequence of older Carboniferous rocks bounded to the west by the Kingscourt Fault. The Kingscourt Sandstone Formation (KS) consists of a lower siltstone unit which grades upwards to a thickly bedded, cross laminated red sandstone. This formation conformably overlies the Kingscourt Gypsum Formation (KG). This formation is composed of a basal impersistent conglomerate, followed by a mud dominated sequence of two major gypsum and anhydrite levels.
3 monitoring boreholes were drilled within the site in March 2003 by Southern Pumps Ltd. The type of subsoil and bedrock described in the driller's logs supports the above description of geology in the area. Clay with gravel layers was reported to overlie Chalk. Based on the appearance of Chalk, it is assumed that the bedrock encountered was Gypsum, which would be typical of the geology in this region of Ireland.
Monitoring Locations NBI , B/B2 and C/B3 were in line with the European Communities Environmental Objectives (Groundwater) Regulations. From this it can be concluded that Kilmainhamwood Compost is having no negative impact on the quality of the groundwater.
