New draft guidance from the U.S. Environmental Protection Agency (USEPA) aims to help wastewater utilities, landowners, and the public reduce risk from perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) in biosolids. PFOA and PFOS are two types of per- and polyfluoroalkyl substances (PFAS) and considered to be the most prolific PFAS compounds in the Read More

Insight into Draft Risk Assessment About PFAS in Biosolids
The U.S. Environmental Protection Agency (USEPA) released a draft risk assessment in January of the potential human health risks associated with the presence of toxic per- and polyfluoroalkyl substances (PFAS) chemicals in biosolids. Specifically, the scientific evaluation of PFAS in sewage sludge (biosolids) assessed the risk of two PFAS compounds, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), Read More
