EA Historic UK Water Quality Sampling Harmonised Monitoring Scheme Detailed Data
Download/Access
The Historic UK Water Quality Sampling Harmonised Monitoring Scheme (HMS) detail dataset contains individual determinand results for all sites in the UK Harmonised Monitoring Scheme network from 1974 onwards. The sampling network includes 230 sites which are mainly located at the tidal limits of major rivers or at the points of confluence of significant tributaries. The information held within the HMS includes data on: oxygen and ammonia, nutrients, list II metals and pesticides.
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.
