This dataset comprises of polygons relating to each site identified under the Bathing Water Directive (76/160/EEC); however these polygons have no formal status under the Bathing Water Directive. Where a site corresponds to a Sensitive Area under the Urban Waste Water Treatment Directive (UWWTD) in England & Wales, the polygon for that Sensitive Area is provided. For all other sites the

Natural Resources Wales monitors bathing water sites identified under EC Bathing Waters Directive 2006/7/EC in Wales. Samples are taken throughout the bathing season from May to the end of September and analysed for two parameters: Escherichia coli and intestinal enterococci. A classification of bathing water quality, generally based on 4 years of sample results, is produced for each bathing

The General Quality Assessment (GQA) Headline Indicator scheme or GQAHI (previously known as GQA) was the national indicator for water quality in rivers and canals. It was designed to provide an accurate and consistent assessment of the state of water quality and how it changes over time. These assessments were made for Biological, Chemical and Nutrients and undertaken for discrete river
