After several months of initial monitoring for PFAS under the National Primary Drinking Water Regulations (NPDWR), water systems across the country continue to ask questions about how to interpret these rules, especially the Hazard Index calculation. Late last month, I did a national webinar in which I drilled down into some of the more confusing aspects of the PFAS MCLs and the initial monitoring period. This webinar is now available on-demand:
In the last couple of years, the U.S. EPA and state agencies have stepped up efforts to address lead in the nation’s drinking water. The latest revisions to the EPA’s Lead and Copper Rule (LCR) are set to go into effect on October 16, 2024. Yet, even before those revisions can be implemented, they may be superseded by the Lead and Copper Rule Improvements (LCRI) proposed by the EPA on November 30, 2023. In this article, we examine the LCR, the LCRI, as well as state efforts to control lead in the nation’s drinking water supply.
Issuing federally enforceable limits for PFAS in drinking water was a key action outlined in the U.S. EPA’s 2021-2024 PFAS Strategic Roadmap. In 2023, the agency released its initial proposal. Then, after considering more than 120,000 public comments and a review of the final rule by the Office of Management and Budget (OMB), the final rule was released on April 10, 2024. In this post, we review the different aspects of this rule and its implications for our customers.
Once the U.S. EPA’s final NPDWR (National Primary Drinking Water Regulations) for PFAS are published, state limits will need to be equal to or below those set by the EPA. As we wait for the EPA to publish its final rule, we thought it might be interesting to do a level-set on where drinking water limits stand at the state level.
Feb. 2, 2024 - Happy New Year! As we step into 2024, it’s tempting to look back at 2023 and call it the “Year of PFAS.” After all, a lot happened in the last twelve months. Here are just a few of the actions worth noting:
