What is the most common groundwater contaminant?
Nitrate
Nitrate. Nitrate is the most common chemical contaminant in the world’s groundwater and aquifers. In some low-income countries, nitrate levels in groundwater are extremely high, causing significant health problems. It is also stable (it does not degrade) under high oxygen conditions.
