Description
Indicator refers to concentrations of nitrate (NO3) in groundwater, measured as milligrams per litre (mg NO3/L). Data are taken from well samples and aggregated to annual average values. Nitrate can persist in groundwater for a long time and accumulate at a high level through inputs from anthropogenic sources (mainly agriculture). The EU drinking water standard is limited to 50 mg NO3/L to avoid threats to human health.
