On April 10, 2024, EPA announced the final National Primary Drinking Water Regulation (NPDWR) for six PFAS. To inform the final rule, EPA evaluated over 120,000 comments submitted by the public on the rule proposal, as well as considered input received during multiple consultations and stakeholder engagement activities held both prior to and following the proposed rule. EPA expects that over many years the final rule will prevent PFAS exposure in drinking water for approximately 100 million people, prevent thousands of deaths, and reduce tens of thousands of serious PFAS-attributable illnesses.

WASHINGTON (AP) — The Environmental Protection Agency on Friday designated two forever chemicals that have been used in cookware, carpets and firefighting foams as hazardous substances, an action intended to ensure quicker cleanup of the toxic compounds and require industries and others responsible for contamination to pay for its removal.

The U.S. Environmental Protection Agency finalized the rules Wednesday. The state established a program targeting the hazardous chemicals in drinking water in 2021.
Washington regulators will adopt a drinking water standard the federal government issued Wednesday that’s meant to limit people’s exposure to a class of harmful chemicals used for decades in firefighting foam and manufacturing.

On March 3, 2021 (86 FR 12272; USEPA, 2021a), the United States Environmental Protection Agency (EPA) announced its decision to regulate perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) under the Safe Drinking Water Act (SDWA).

Section 1412(a)(3) of the Safe Drinking Water Act (SDWA) requires the Administrator of the U.S. Environmental Protection Agency (EPA) to finalize a Maximum Contaminant Level Goal (MCLG) simultaneously with the publication of a National Primary Drinking Water Regulation (NPDWR). The MCLG is set, as defined in Section 1412(b)(4)(A), at “the level at which no known or anticipated adverse effects on the health of persons occur and which allows an adequate margin of safety.” Consistent with SDWA 1412(b)(3)(C)(i)(V), in developing the MCLG, the EPA considers “the effects of the contaminant on the general population and on groups within the general population such as infants, children, pregnant women, the elderly, individuals with a history of serious illness, or other subpopulations that are identified as likely to be at greater risk of adverse health effects due to exposure to contaminants in drinking water than the general population.” Other factors considered in determining MCLGs for drinking water contaminants include health effects data, toxicity values, cancer classifications, and potential sources of exposure other than drinking water. MCLGs are not regulatory levels and are not enforceable.

The methods used to conduct the systematic review for PFOA are consistent with the methods described in the draft and final EPA ORD Staff Handbook for Developing IRIS Assessments (U.S. EPA, 2022b, 2020a) (hereafter referred to as the Integrated Risk Information System (IRIS) Handbook) and a companion publication (Thayer et al., 2022).

This letter report summarizes the procedures and results of supplemental sampling of stormwater for analyses of per- and polyfluoroalkyl substances (PFAS) at tge Edmonds School District No. 15 (ESD) Madrona K-8 School Replacement Project (Project). The purpose of this voluntary sampling event was to objectively evaluate for the presence of PFAS in stormwater following stormwater sampling conducted by Olympic View Water abd Sewer District (OVWSD) on October 22, 2022. Because the procedures used to collect stormwater samples by OVWSD were not provided, the usability and validity of their data are unknown. A map of the project location is provided as Figure 1. This letter is revised from the final version dated February 8, 2024, to correct the pagination.
