Statistical data set

ENV-16 Harmonised Monitoring Scheme datasets

Additional annual datasets on river water quality.

Additional data sets on river water quality in Great Britain collected by the Environment Agency under the Harmonised Monitoring Scheme. This provides information about nutrient and heavy metal loads entering the marine environment and contributes to our commitment to report figures to the OSPAR Convention for the Protection of the North Atlantic. Full details available at: OSPAR - Riverine Inputs and Direct Discharges

The full dataset will be available from the Environment Agency datashare site. From November 2013

Release statement - Following a review by Defra and the Environment Agency on reducing the monitoring programme where it is not required under the present regulatory regime, it has been decided that the monitoring under the Harmonised Monitoring Scheme will be discontinued.
