An environmental advocacy group lists Bloomington among more than 600 locations across the United States whose water may be contaminated with a highly toxic compound, while city officials maintain the city’s water is safe.
The Environmental Working Group recently released a report which indicated Bloomington tested positive for trace levels of PFAS (Perfluoroalkyl and polyfluoroalkyl substances). The group claims as of March, the compound has been detected in 43 states, potentially contaminating the drinking water systems of more than 19 million people.
A test in 2013 detected PFAS at 47 parts-per-trillion in Bloomington’s groundwater, which falls below the Environmental Protection Agency’s advisory threshold for 70 parts-per-trillion which would trigger mitigation.
“It’s not as great a concern as what we have seen in some other contaminated systems, but certainly it’s a level that if it were I my water, I wouldn’t be drinking it without a filter,” said Bill Walker, editor in chief of EWG.org.
