However, the environmental fate of emerging contaminants and their behavior is largely unknown. Sometimes chemicals that had not previously been detected (or were previously found in far lesser concentrations) are discovered in the water supply. As the water that contains chemicals moves … This information, as well as emerging data from future studies, should be considered in the development of health-protective and scientifically sound guidelines for PFAAs in drinking water. Contaminants of emerging concern (CECs) is a term used by water quality professionals to describe pollutants that have been detected in water bodies, that may cause ecological or human health impacts, and typically are not regulated under current environmental laws. Some compounds are being studied to better assess how standards for those contaminants can be developed. This will include an introduction to the principles of assessing chemical and pathogen risks, which will then be applied to a range of emerging contaminant risk contexts including: novel sanitation … Unregulated synthetic or naturally-occurring chemicals that are not commonly monitored by water utilities are termed "contaminants of emerging concern" (CECs). Below, you’ll find a list of common primary, secondary, and emerging drinking water contaminants.
