(GenX). PFBS, PFNA, PFHxS, and Gen X will also be regulated together as a group using a unitless hazard index. These values are grounded in the health-based MCLGs (of 0—meaning that they conclude that there is no safe level of these compounds in drinking water) but also incorporate ...
Protection Agency (EPA) hasfinalizeda national Primary Drinking Water Regulation (NPDWR),establishingenforceable Maximum Contaminant Levels (MCLs) for six (6) per and polyfluoroalkyl substances (PFAS). This announcement marks a significant step forward in ensuring safe drinking water for communities...
this project establishes a framework for the evaluation and delivery of an affordable solution to ensure people have access to safe drinking water not just in the US, but around the globe. WSP continues to explore new ways to help these communities take the critical...
" said Romano, who studies the effects of PFAS and other endocrine-disrupting chemicals in drinking water on New England communities. "We saw that as a knowledge gap in the literature, especially for a New England state where we know people love their seafood."...
are used in nonstick cookware, water-repellent clothing and firefighting foam. Their manufacture and persistence in products have contaminated drinking water nationwide. Also known as "forever chemicals," these substances do not break down in the environment and can accumulate in our bodies over time...
and that almost no level of exposure was safe. it advised that drinking water contain no more than 0.004 parts per trillion of perfluorooctanoic acid and 0.02 parts per trillion of perfluorooctanesulfonic acid, the two chemicals among the six given the highest priori...
In February 2020, the EPA issued preliminary determinations to regulate PFOA and PFOS under the Safe Drinking Water Act (SDWA) and establish the first national PFAS monitoring and treatment requirements for drinking water utilities (see EPA’sPFAS Action Plan). Numerous U.S. states, however,have...
The Upshot Massachusetts is joining a small number of states that have established an MCL for PFAS. This puts Massachusetts ahead of US EPA’s regulatory process under the federal Safe Drinking Water Act. Only time will tell if Massachusetts has moved too quickly. [View source.]Send...
The researchers found high levels of PFAS in various regions, including Australia, particularly in areas historically exposed to firefighting foams, such as military and fire training facilities. “Drinking water is largely safe, and I don’t hesitate drinking it,” O’Caroll said. “I also don...
level (“LHA”) of 70 parts per trillion (“ppt”) for drinking water in 2016. The EPA’s LHA is non-enforceable and non-regulatory, however, institutions such as the Department of Defense, among others, have taken actions to restrict or shut down water systems that contain concentrations ...
