Nitrate Sensitive Areas

NSAs are carefully selected areas covering groundwater sources used to supply drinking water. In these areas incentives were offered to farmers to undertake significant changes in agricultural practices to reduce nitrate leaching, thereby helping stabalise or reduce nitrate levels. There are 32 NSAs in England. Note this scheme is now closed to new applicants Attribution statement: © Natural England copyright.
