Envirologic work together with HydroG (www.hydro-g.com) to compile EIAR Chapters (i) Land, Soils & Geology, and (ii) Water, for quarries in Ireland.  The EIAR is submitted as part of planning applications to local authorities when a quarry intends to access additional bedrock either by deepening or expanding the footprint.   

The aim of this work is to quantify the amount of groundwater likely to enter the quarry void as it gets bigger.  This involves well drilling and pumping tests which helps to understand the local groundwater flow regime and assess the likely impacts on the aquifer. This groundwater is then removed by pumping to provide a dry working floor.  The team provide specifications for settlement ponds to clean the pumped water and a comprehensive assessment of local streams is carried out to check whether the water can leave the site without having a detrimental impact on local habitats or causing flooding.  These final aspects are regulated by way of a discharge license.
