sediment, or be nitrified if oxygen is present. Nitrate is the form of N taken up by plants, so emergent plants use it during the growing season. Excess nitrate in an anaerobic system is reduced to N2 and N2O gases as a result of denitrification, the main mechanism of nitrate removal. Some wastewaters contain phosphates from cleaning products.

Groundwater pollution - Wikipedia
Groundwater pollution - Wikipedia

Groundwater pollution, (also called groundwater contamination) occurs when pollutants are released to the ground and make their way down into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
