Per- and Poly-Fluoroalkyl Substances (PFAS) are a large family of organic compounds, including more than 3,000 manufactured fluorinated organic chemicals used since the 1940s.
PFAS have unique surfactant properties that make them repel water and oil. They have been used extensively in aqueous film‑forming foams (AFFF) to extinguish class B (flammable liquid) fires; surface coatings and protective formulations for paper and cardboard packaging products; stain, wrinkle - and water-resistant and repellent fabrics; mist-suppressant foam blankets for chromium plating; nonstick products, polishes, waxes, paints and cleaning products; as well as industrial surfactants, emulsifiers, wetting agents, additives and coatings.
Due to their widespread use and persistence in the environment, most people in the U.S. and in countries around the world have been exposed to PFAS. Studies indicate that exposure to some PFAS may lead to adverse health effects.
Jacobs’ solutions for PFAS contamination are truly interdisciplinary, encompassing our environmental, water, wastewater, solid waste, aviation, and private industry expertise. We challenge today and reinvent tomorrow by combining deep knowledge of our clients’ operations and processes with a thorough understanding of PFAS chemical behavior and proven treatment approaches.
Workshop on the State of PFAS in Colorado
This workshop looks at per-and polyfluoroalkyl substances (PFAS) from a national and state level point of view, serving as a platform for experts from various organizations to share their knowledge and insights on PFAS progress and regulatory considerations, Colorado Department of Public Health and Environment (CDPHE) PFAS Narrative Policy, PFAS in drinking water, and pilot project highlights from the Orange County Water District (OCWD).
Todd Williams: BioCycle
To better understand how composting wastewater impacts PFAS concentrations within biosolids composts, Todd Williams, a senior principal technologist at Jacobs shares findings from sampling a small group of biosolids composting operations. He shares what was learned and calls for next steps in this article in BioCycle.
