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.

During oil and natural ,gas production,, so-called “produced water” comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic fracturing (HF) fluids into the formation. Both produced water and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public health and the environment.
