PFAS INFORMATION

On behalf of our members, CASA has been exceptionally active on all facets of per- and polyfluoroalkyl substances (PFAS). Activities include sponsoring state legislation, supporting federal legislation, commenting on developing state and federal regulatory policies, tracking litigation, hosting deep-dive webinars, preparing communication materials and fact sheets based on sound science, and many others. The intent of this overview is to provide a summary of CASA’s actions over the last few years, as well as share links to the many resources and materials available to our members for reference and use….Read More

The goal of this study was to fully evaluate the potential impact of land application on groundwater contamination by PFAS. Known as “forever chemicals” because most are resistant to microbial degradation, once PFAS are introduced into the environment they persist. They are ubiquitous and found in most soils, sediments, and water. All people in the U.S. are thought to have PFAS in their blood, with longer chain compounds like PFOA and PFOS remain in the body….Read More

The intent of this document is to share what has been learned about PFAS in biosolids since implementation of the updated Interim Strategy, and to provide updates to the Interim Strategy based on this new information for biosolids land-applied in Michigan. As implementation of the Interim Strategy is ongoing, EGLE’s goal remains for wastewater treatment plants to continue reducing PFAS concentrations in biosolids to the maximum extent practicable, while achieving or maintaining…Read More

An increasingly urbanized and populous nation requires effective and efficient systems for managing municipal waste streams – systems that safeguard human health and the environment and advance sustainability. The wastewater treatment cycle is essential to protecting public health, advancing water quality, and bolstering vibrant communities, and is a true benefit of…Read More

This field study investigated the impact of long-term land application of biosolids on PFAS presence in soils that received annual repetitive land application of Class B biosolids from 1984 to 2019. Soil samples were collected from three depths of 30.5, 91 and 183 cm below land surface. Biosolid and groundwater samples used for irrigation were also collected. Concentrations measured for 18 PFAS compounds were evaluated to assess…Read More

Per- and polyfluoroalkyl substances (PFAS) are a family of more than 9,000 synthetic organic chemicals. PFAS can withstand high temperatures and survive highly corrosive environments. A Chemical Action Plan (CAP) identifies, characterizes, and evaluates uses and releases of a specific Persistent Bioaccumulative Toxin (PBT), a group of PBTs, or metals of concern….Read More

Human exposure to per- and polyfluoroalkyl substances (PFASs) continues to be a concern. Little is known about their toxicokinetics, particularly with regard to fecal excretion of PFASs. Because pets are sentinels of human exposure to environmental contaminants, analysis of PFASs in pet feces can provide information about rates of excretion of these chemicals. In this study, 15 PFASs were measured in cat and dog feces collected from the Albany area of New York State…Read More
