PFAS STORIES
EPA Announces Partnership to Prevent and Manage PFAS in Biosolids
“One of the most effective near- and long-term solutions to reducing PFAS in biosolids is to prevent PFAS from entering wastewater treatment facilities in the first place.” The latest science is clear: long-term exposure to PFAS is linked to significant health risks, and PFAS can enter our water and land through several different paths. That’s…
PFAS and Biosolids: What Wastewater Pros Need to Know
Coverage of PFAS is supported by Carollo. The toxicity and widespread detectability of certain per- and polyfluoroalkyl substances (PFAS) have raised concern about their potential health impacts or changes to water and wastewater practices in response. PFAS are commonly present in water, human blood, environmental samples, household products, and biosolids (Ducatman et al., 2022; Hu…
Column: Initial Thoughts on EPA’s Proposed PFAS Standards
As regular readers of my blog are likely aware, this week EPA announced proposed Maximum Contaminant Limits (MCLs) of 4 ppt for PFAS in U.S. drinking water utilities. I’m a social scientist, not a toxicologist or engineer. I can’t speak to health risks or the benefits of regulating PFAS. I can’t address the feasibility of…

Every four years, EPA selects national initiatives to focus resources on serious and widespread…
Breaking Down the Facts about PFAS in Biosolids
Coverage of PFAS is supported by Carollo. In 2018, the media seized on a story about a small dairy farm in Maine that was forced to no longer produce milk due to sludge and biosolids spread on the farm as fertilizer under a state-sponsored program from 1983 to 2004. Wastewater utilities were quickly blamed for…
CASA Releases Fact Sheet on PFAS
View CWEA’s PFAS resources page, support by Carollo.

OC San operates a state-of-the-art Environmental Sciences…
A Critical Need: Supercritical Water Treatment for PFAS Elimination
The practice of treating wastewater has existed since the 19th century, beginning with centralized designs to keep sewage discharge out of clean water sources. Around this time, efforts to separate storm runoff from wastewater was also introduced in many communities. Fast forward to today, decades of focus on the environmental impact of waste treatment and…
OC San Helping to Pinpoint the Sources of PFAS
Mark Kawamoto and his team at Orange County Sanitation District, also known as OC San, are trying to solve a riddle: “How does PFAS make its way into water resource recovery facilities?” PFAS are in wastewater that is treated at water resource recovery facilities (WRRFs), including at OC San’s two facilities, but the source of…
Synthetic “Forever Chemical” Linked to Liver Cancer
View CWEA’s PFAS resources page, support by Carollo.

These chemicals, which…
EPA Announces Plans for Wastewater Regulations and Studies
View CWEA’s PFAS resources page, support by Carollo. The U.S. Environmental Protection Agency (EPA) released Effluent Guidelines Program Plan 15 (Plan 15), which lays out how the Agency will work to protect the nation’s waterways by following the science and the Clean Water Act to develop technology-based pollution limits and studies on wastewater discharges from…
The Ill-Foreverness of PFAS
View CWEA’s PFAS resources page, support by Carollo. It is a fact that chemistry has changed our world for the better. It has played an important role in the production of commercial products, thus making a great variety of raw materials accessible to manufacturers across all industrial sectors and leading to the production of many…
PFAS Legislation We Have Seen in 2022
The California Legislature has taken action to limit the use of PFAS in recent years, enacting bills to phase them out of food packaging, banning their use in nearly all firefighting foam, and requiring notification on cookware containing PFAS. Three bills relating to PFAS were passed in the 2022 Legislative Session. The bills included two…
Seven Habits of Highly Effective PFAS Source-Trackers
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous, including detectable amounts typically in the parts per trillion (ppt) range in wastewater effluent and parts per billion (ppb) range in solids. The US EPA plans to publish ambient water quality human-health-based criteria for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) by Fall 2024. The EPA also…
PFAS Legislative & Regulatory Developments in California
Per and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals, often called “forever chemicals” because they are extremely resistant to breaking down and they persist in the environment and the human body, leading to continued exposure and health risks into the future. Despite these problems, PFAS are widely used by industry and are in…
Removing PFAS Starts at The Source
Stories about PFAS have multiplied as we discover more about these “forever chemicals.” They’ve been in our lives since the 1940s – used in clothing, carpets, couches, cookware, cosmetics, and more – but we had no idea until this century that prolonged exposure could be harmful to our health. At least 80 percent of PFAS…
