But nobody knows how much of that fertilizer is contaminated with PFAS, which can be absorbed by crops, consumed by livestock, and then enter the food supply. There are no requirements to test biosolids for PFAS, or to warn farmers and ranchers that they could be using contaminated fertilizer made with biosolids on their land.
“Some people are saying, [PFAS contamination] are isolated incidents. No, they’re not. I guarantee that this is a problem in every single state that uses biosolids,” said Kyla Bennett, a former U.S. Environmental Protection Agency employee who is now a science policy director for the nonprofit group Public Employees for Environmental Responsibility.
“The reason we’re not hearing about it all over the country, in all 50 states, is because nobody’s looking for this problem,” Bennett added.
