Water quality data archive

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 November 2016. Currently, the data does not include all groundwater data nor externally supplied data. Data may be subject to change after publication. We are looking at improvements to the service, including more frequent updates.
