EPA commence consultation on determining groundwater pollution
09 February 2017
The EPA has commenced consultation on Determining Groundwater Pollution: A proposed approach for the development and application of guideline values for groundwater. The closing date for comments is 5pm, February 28, 2017 and input is welcomed from all stakeholders
A clear understanding of what is ‘pollution’ is required for a number of reasons:
to provide a common framework across all regulatory regimes for determining pollution of groundwater and to determine the extent of ground contamination at licensed sites;
to determine concentrations in groundwater below which the danger of deterioration in the quality of the receiving groundwater is avoided;
to assess compliance with the Environmental Objective (Groundwater) Regulations;
to determine if the ‘prevent or limit’ objective is being met; and
to demonstrate that significant upward trends in concentration have been reversed and/or that any associated contaminant plumes are not expanding.
In order to assess compliance with the EU Water Framework Directive (WFD), there is firstly a need to determine if the inputs of hazardous / non-hazardous pollutants have been prevented / limited. If they have not then the next step is to determine if the pollution has occurred as a result of the associated activities. It is important to note that for pollution to occur there needs to be some actual or likely impact on drinking water sources, surface water or wetlands, or an impact that would impair future use of groundwater e.g. as a source of potable water. Secondly, the extent and significance of the pollution (plume) needs to be determined as it influences the intervention that is required.
