NVZ Policy and Monitoring


The Scottish Government Water, Air, Soils and Flooding staff are responsible for maintaining and improving the quality of the water environment, both fresh and marine waters, in Scotland. For these purposes a number of Nitrate Vulnerable Zones (NVZs) have been identified in Scotland in order to protect human health and living resources from pollution to surface waters and groundwater, caused by nitrate from agricultural sources. The Government carries out a review of the designations at least every 4 years in line with the Nitrates Directive. The following reports summarise previous two NVZ designation reviews in Scotland:


The Scottish Environment Protection Agency (SEPA) monitors nitrate concentrations in surface and groundwaters on behalf of the Scottish Government, with the aim of reducing water pollution caused by nitrates.
