About Thursday Contaminant Roundup: Each week we bring to you headlines from around the world where water contaminants pose issues for local communities. From arsenic to PFAS, contaminants can be found in various levels and forms and should be addressed with in order to maintain clean water for all. This is your weekly dose of water contaminant news.
October 16, 2019 — Michigan’s governor has proposed limits on seven types of PFAS in the state’s public drinking water system. The proposal would cover 2,700 public water supplies across the state, but would not impact those who draw water from their own well. Four other states have adopted similar PFAS regulations. The final rule could be adopted by next April.
October 14, 2019 — California state officials conducted testing of more than 600 wells across the state and found that nearly 300 drinking water wells have traces of PFAS. The state plans to expand on this first round of testing, which focused on wells located near airports, landfills and water supplies already known to have elevated levels.
October 10, 2019 — A new EPA proposal would change how communities test and communicate about lead in drinking water. Under the new proposal, water systems would also be required to keep a publicly-available inventory of lead service lines, and utilities must notify customers within 24 hours if a home water test shows dangerous lead levels. The proposal does not change the existing action level of 15 ppb, but establishes a lower 10 ppb trigger level, which would compel water systems to identify actions that would reduce lead levels.
September 23, 2019 — The Centers for Disease Control and Prevention and the Agency for Toxic Substances and Disease Registry are beginning a multi-site study to investigate health outcomes related to PFAS contamination in drinking water. Seven institutions were awarded $1 million each to look at exposures in their communities, which include cities in Colorado, Michigan, Pennsylvania, New Jersey, New York, Massachusetts and California. The study will recruit children and adults who were exposed to PFAS-contaminated drinking water.
