Nitrate Vulnerable Zones

Nitrate Vulnerable Zones (NVZs) are areas within Scotland that contain surface water or groundwater that is susceptible to nitrate pollution from agricultural activities. They are designated in accordance with the requirements of the European Commision's Nitrates Directive 91/676/EEC, aims to protect water quality across Europe by preventing nitrates from agricultural sources polluting ground and surface waters and by promoting the use of good farming practices. The Scottish Government is responsible for maintaining and improving the quality of the aquatic environment, and carries out a review of the NVZ areas every four years. In 2016, five areas of Scotland were designated as NVZs under the following regulations: The Designation of Nitrate Vulnerable Zones (Scotland) Regulations 2014 (SSI 2014/373). The five NVZ areas were designated as nitrate levels from agricultural sources either resulted, or would likely result, in a concentration equal or exceeding 50 milligrammes of nitrate per litre of water in either surface water or groundwater. The five areas within Scotland, currently designated as NVZs, are: Aberdeenshire, Banff, Buchan and Moray, Strathmore and Fife, Stranraer Lowlands, Edinburgh, East Lothian and Borders, and Lower Nithsdale. NVZs were most recently reviewed in 2017 and it was concluded that no changes to the data were required.
