The EPA could soon face a lawsuit for not protecting farmers from “forever chemicals.”
Biosolids are a type of treated sewage byproduct that make a nutrient-rich fertilizer, but PFAS are slipping through the cracks of wastewater treatment and could be contaminating millions of acres of farmland.
Few states have regulations on what level of PFAS are safe in biosolids. A group of farmers in the northeast are now demanding the EPA implement federal standards.
Sarah Alexander leads the Maine Organic Farmers and Gardeners Association, which filed the notice against the EPA. She said the federal government needs to step up and ensure biosolids are safe.
“We do believe the EPA has a responsibility here, and we need federal action,” Alexander said. “State-by-state action on this isn’t enough to address the full scope of this issue.”
PFAS are a group of more than 15,000 chemicals that are associated with various cancers, decreased immune response, liver disease and reproductive or developmental issues, among other adverse health outcomes.
But these chemicals don’t break down, and most wastewater plants can’t treat them. Routine testing for PFAS at plants is also still sparse across the Midwest.
Michigan is one of few states in the country that requires wastewater plant testing and has standards for what levels are acceptable in biosolids.
If wastewater plants detect two compounds, PFOA and PFOS, above 100 parts per billion (ppb) in biosolids, they are considered “industrially impacted” and can no longer be applied to land. If they’re under 20 pbb, they’re in the clear.
So far, the state has only shut down one farmer.
Jason Grostic, a beef farmer in southeast Michigan, was ordered to stop selling his products after using contaminated biosolids on his land. He previously told Harvest Public Media he felt like the rug had been pulled out from under him when he was forced to close.
“I took a fertilizer source that was recommended and was EPA-approved, and the government dropped the ball by not testing it and assuring it was a clean product,” Grostic said.
Grostic is now on the brink of bankruptcy while still caring for more than a hundred cows, and engaged in a lawsuit against the auto parts supplier, which released PFAS into the wastewater system.
He said he was never warned of the risks of PFAS in biosolids and supports more protections like financial safety nets for farmers.
“As a farmer that can’t farm nothing, what am I supposed to do?” Grostic said.
