12. A Schedule shall be inserted into the Groundwater Regulations (Northern Ireland) 2009 as follows:
Regulation 8
Parameter | Unit | To examine if groundwater abstraction is causing saline or other intrusions | To examine if groundwater is providing a significant contribution to the failure of the environmental objectives of associated surface water bodies | To examine if the quality of groundwater that is abstracted for potable use is deteriorating, possibly resulting in a need for increased purification | To examine the spatial extent of a groundwater body or group of bodies that are exceeding an EU Standard or threshold value |
---|---|---|---|---|---|
(1) The surface water environmental standards are set out in Schedule 1 to The Water Framework Directive (Priority Substances and Classification) Regulations (Northern Ireland) 2011(S.R. 2011 No. 10) | |||||
(2) The “dilution factor” is taken to be the fraction of the average annual river flow derived from groundwater inflows. It can be estimated from established hydrological indices such as the baseflow index, or from the ratio of catchment groundwater recharge to effective precipitation. | |||||
