Which parameter is NOT typically included in groundwater quality assessments?

In groundwater quality assessments, various parameters are measured to evaluate the health and safety of the water supply. Temperature, while an important physical characteristic of water, does not typically form a part of routine assessments focused on contamination and chemical quality. Instead, assessments generally concentrate on identifying pollutants and threats to human and ecological health.

Parameters like nitrogen and phosphorus levels are critical in assessing eutrophication risks, particularly in the context of agricultural runoff. Heavy metals represent significant contaminants that can pose toxic risks to human health and the environment, making their measurement crucial. pH levels are also fundamental since they affect the solubility and mobility of various contaminants and nutrients in groundwater.

While temperature can influence biological activity and chemical reactions in groundwater, it is less often a direct indicator of quality compared to the other items listed. Therefore, it is not considered a standard parameter in routine groundwater quality assessments.
