. Description: In the past decade, the scientific community and general public have become increasingly aware of the potential for the presence of unregulated, and generally unmonitored contaminants, found at low concentrations (sub-ug/L) in surface, ground and drinking water. EPA is moving in Analytical methods developed by EPA to identify and measure certain contaminants of emerging concern. Three specific examples will be used: per- and Polyfluoroalkyl Substances (PFAS), cyanotoxins, and perchlorate. Analytical methods developed by EPA to identify and measure certain contaminants of emerging concern. The U.S. currently has more than 80,000 chemicals in commerce. Contaminants of Emerging Concern Under the Clean Water Act Congressional Research Service 1 Introduction Over the past couple of decades, national attention to "emerging contaminants" or "contaminants of emerging concern" (CECs) in surface water and groundwater has been increasing. See EPA's About PDF page to learn more. The U.S. Environmental Protection Agency (EPA) has made a final determination not to regulate 11 contaminants on the second drinking water contaminant candidate list (CCL 2). Emerging contaminants (ECs), also known as emerging organic contaminants (Jurado et al., 2012; Lapworth et al., 2012) and contaminants of emerging concerns (CECs) (Dulio et al., 2018), are a group of natural and synthetic chemicals and their transformation products occurring in water bodies throughout the globe, which are presently not . Technical Fact Sheets about Contaminants of Concern at Federal Facilities.
