Nitrate Vulnerable Zones (NVZ)

Understanding the Nitrate Vulnerable Zones map and data

Go to the Nitrate Vulnerable Zones (NVZ) map

 

The European Commission (EC) nitrates directive requires areas of land that drain into waters polluted by nitrates to be designated as Nitrate Vulnerable Zones (NVZs).

Farmers with land in NVZs have to follow mandatory rules to tackle nitrate loss from agriculture. 

 

Key to understanding the Nitrate Vulnerable Zones map:

Proposed (2017 - 2020) Nitrate Vulnerable Zones

The 2017 Nitrate Vulnerable Zones are the NVZ boundaries which are proposed to apply in 2017.

  Surface Waters - areas of land that drain into a freshwater water body which has or could have is action is not taken, a nitrate concentration greater than 50mg/l

  Groundwater - water held underground in the soil or in pores and crevices in rock, which has or could have if action is not taken, a nitrate concentration greater than 50mg/l

  Eutropic Waters - bodies of water, mainly lakes and estuaries, that are or may become enriched by nitrogen compounds which cause a growth of algae and other plant life that unbalances the quality of the water and to organisms present in the water .

Proposed (2013 - 2016) Nitrate Vulnerable Zones

The 2013 Nitrate Vulnerable Zones are the NVZ boundaries which apply from 1 January 2013.

  Surface Waters - areas of land that drain into a freshwater water body which has or could have is action is not taken, a nitrate concentration greater than 50mg/l

  Groundwater - water held underground in the soil or in pores and crevices in rock, which has or could have if action is not taken, a nitrate concentration greater than 50mg/l
