In 2016, five areas of Scotland were designated as NVZs. The five NVZ areas were designated as nitrate levels from agricultural sources either resulted, or would likely result, in a concentration equal or exceeding 50mg/l of nitrates 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.
