Concerns rise over tainted sewage sludge spread on croplands
News
12 Sep 2019 | Associated Press
Several states are examining sewage sludge for PFAS contamination and assessing potential dangers. Maine has enacted a nonbinding advisory level for PFAS in sludge and New Hampshire is working with the U.S. Geological Survey on a soil study whose results will help them set a standard. Maine also found most biosolids from more than 30 wastewater treatment plants were above the state's advisory level while neighboring New Hampshire detected PFAS in tests of sludge from two dozen permit holders. Neither state found traceable levels of PFAS in the milk tested. Based on sludge tests at 41 plants, Michigan ordered several to stop distributing it to farms.
