UK River water quality data

The Water Quality Archive provides data on water quality measurements. Samples are taken from sampling points round the country, including: agricultural, coastal, estuary, rivers, lakes, ponds, canals, sewage discharges, trade discharges, pollution investigation points and waste sites. The archive provides data on these measurements and samples dating from 2000 to December 2015. When we update the data, we will update this home page. Currently, the data does not include groundwater data or externally supplied data. Data may be subject to change after publication. Please contact us if you require more information.
