Our exposure to per- and poly-fluoroalkyl substances (PFAS) is a major health concern due to their widespread occurrence and adverse health effects. Mounting evidence indicates that PFAS pollution, even at low levels, affects human development and reproductive functioning.
Elevated nitrate concentration is a multifaceted problem. In surface water and groundwater, it can cause eutrophication. When present in drinking water, nitrate can threaten human health – for example, it can cause methemoglobinemia in infants. Thus, finding a way to remove nitrates from water is important for human and environmental health.
In the past, the assessment and management of groundwater contamination has been driven by contaminant concentrations. However, concentration data alone are sometimes not sufficient to fully understand the behaviour or effect of a plume over time.
