PLEASE NOTE: This dataset has been retired, as it has been superseded by the dataset for Nitrate Vulnerable Zones (NVZ) 2021 Designations. See: https://environment.data.gov.uk/dataset/60be356d-6475-4d51-9572-9f8c09f1a764

This dataset sets out the Nitrate Vulnerable Zone designations following the 4 yearly review for implementation in 2017. These were the designations prior to appeals.

This dataset supersedes the previous dataset ‘Nitrate Vulnerable Zones (NVZ) 2013 - Combined (Final Designations)’. This dataset is superseded by the current data 'Nitrate Vulnerable Zone (NVZ) 2017 - Combined (Final Designations)'.

Nitrate Vulnerable Zones (NVZs) are areas designated as being at risk from agricultural nitrate pollution. The designations are made in accordance with the Nitrate Pollution Prevention Regulations 2015.

Waters are defined within the Nitrates Directive as polluted if they contain or could contain, if preventative action is not taken, nitrate concentrations greater than 50mg/l.
