Please choose a part of England to view maps of the NVZs.

The Nitrates Directive requires all known areas of land which drain into polluted waters to be designated as NVZs. Polluted waters are defined as follows.

(a) Surface freshwaters which contain or could contain, if preventative action is not taken, nitrate concentrations greater than 50 milligrammes per litre (mg/l).

(b) Groundwaters which contain or could contain, if preventative action is not taken, nitrate concentrations greater than 50mg/l.

(c) Natural freshwater lakes, or other freshwater bodies, estuaries, coastal waters and marine waters which are eutrophic or may become so in the near future if preventative action is not taken.

For a full explanation of the steps taken to identify the new NVZs in England please refer to the Defra NVZ web pages.
