Emerging contaminants are known to cause endocrine disrupting activity and other toxic mechanisms, some are recognized as known carcinogens by the United … Home » EPA’s PFOA and PFOS “Hazardous Substance” Designation Process ... For the past several years, much attention has been focused on the United States Environmental Protection Agency’s (EPA) … These methods are not approved under 40 CFR Part 136, but may be of interest to regulated entities, permitting authorities, and the public. An “emerging contaminant” is defined by the U.S. Environmental Protection Agency (EPA) as a chemical or material that is characterized by a perceived, potential, or real threat to human health or the environment or by a lack of published health standards. An “emerging contaminant” is a chemical or material that is characterized by a perceived, potential, or real threat to human health or the environment or a lack of published health standards. Classified as “emerging contaminants” or “contaminants of emerging concern” by the EPA, these chemicals are not well researched but have been found to cause cancer or affect the liver, immune system, cholesterol levels, and thyroid. Contaminants of emerging concern (CECs), can be introduced into drinking water prior to, during, or after treatment. EPA Publication Number: EPA 505-F-17-001. This fact sheet provides a summary of two contaminants of emerging concern, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), including physical and chemical properties; environmental and health impacts; existing federal and state guidelines; detection and treatment methods; PFAS and Emerging Contaminants. The Biden Administration has also signaled it will address emerging contaminants. General information on emerging contaminants, as well as perchlorate, nanomaterials, and … Analytical methods developed by EPA to identify and measure certain contaminants of emerging concern. As noted by Steve Siros in Wednesday's Corporate Environmental Lawyer Blog , EPA is likely to designate per- and polyfluoroalkyl substances (“PFAS”) as “hazardous substances” under CERCLA and may set a maximum contaminant level (“MCL”) for these compounds under the Safe Drinking Water Act (“SDWA”). This is especially true for most CECs in coastal ecosystems such as Narragansett Bay. EPA. PFAS: Contaminants of Emerging Concern PFAS, or per- and polyfluoroalkyl substances, are persistent synthetic compounds used in a variety of industrial and consumer product applications including non-stick cookware and firefighting foams.
