“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...

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...

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...

Today, there are 20 labs in California accredited for PFAS testing, OC San and the Inland Empire Utilities Agency are the only approved municipal labs. OC San operates a state-of-the-art Environmental Sciences...

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...

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...

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...

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...

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...

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...
