Completion of a Tier 2 Hydrogeological Assessment in relation to discharge of treated wastewater to ground as part of Planning Permission for a commercial development on the banks of the River Shannon, County Clare.
The works involved an assessment of the site geological and hydrogeological properties by use of trial pitting and groundwater monitoring well installations.
A Tier 2 assessment comprises an assessment of past monitoring data, past hydrogeological assessments and publicly available data (e.g. EPA, GSI databases), in addition to further monitoring and a comparison of monitoring results with Generic Assessment Criteria (e.g. Groundwater limits stipulated as per the Groundwater Regulations, 2010).
