The Water Quality Archive provides data on water quality measurements carried out by the Environment Agency. Samples are taken from sampling points round the country and then analysed by laboratories to measure aspects of the water quality or the environment at the sampling point. The archive provides data on these measurements and samples dating from 2000 to present day. It contains 58 million measurements on nearly 4 million samples from 58 thousand sampling points.
The archive provides an API to allow selective access to the data, together with the ability to download the data split into either pre-defined or customizable subsets. The data is made available in CSV, JSON and RDF formats.
