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.
September 6, 2019 — Research from Oregon State University published in Environmental Science and Technology shows that toughening the federal standard for arsenic has led to fewer violations by public water systems. Researchers analyzed 12 years of data from the EPA’s Safe Drinking Water Information System database. They found that toughening the standard has resulted in 1 million fewer people drinking water that was out of compliance for arsenic.
September 12, 2019 — Testing of the groundwater in metro Denver has found PFAS levels well above the federal health advisory limit. As part of a new action plan, Colorado will establish maximum contaminant levels and increase the capacity for testing. Fire departments will no longer be allowed to use PFAS during training, and must limit the use of firefighting foam at airports.
September 13, 2019 — Millions of people across the U.S. get their drinking water from lead pipes, and water crises in places like Flint, Michigan and Newark, New Jersey have officials rethinking the best way to keep the drinking supply safe. Some experts argue that the lead service lines should be replaced rather than treated, but this is a difficult and expensive task. Few states require maps of their locations, meaning that dozens of states are unaware of how much lead plumbing they have.
