Natural Resources Wales's monitoring networks for groundwater level and quality: the story so far

Natural Resources Wales, which was formed in April 2013, has taken over the functions of the Countryside Council for Wales, Environment Agency Wales and Forestry Commission Wales, as well as some functions of Welsh Government. Its purpose is to ensure that the natural resources of Wales are sustainably maintained, enhanced and used, now and in the future. This includes ensuring that the quality of groundwater, surface water and coastal waters continues to improve. In Wales, groundwater only contributes around 3% of the total public water supply (Environment Agency, 2008a). However, it is still an important resource in rural areas where records held by local authorities identify at least 21,000 private water supplies, typically comprising shallow wells, boreholes and spring sources. Groundwater also provides baseflow to rivers and groundwater dependent wetlands. Therefore it is important that sufficient data is available to understand, manage, protect, forecast and report on the quality and availability of groundwater.
