UK Water Quality Sampling Harmonised Monitoring Scheme Detailed Data

The Historic UK Water Quality Sampling Harmonised Monitoring Scheme (HMS) dataset contains individual determinand results for all sites in the UK Harmonised Monitoring Scheme network from 1974 until 2013. The Harmonised Monitoring Scheme (HMS) was established to provide an archive of water quality data for the UK. It is used to provide information for international obligations, including the long-term trends of some determinands and the estimation of riverborne input of selected determinands to the sea.
