How do facilities transition from AFFFs?

How do facilities transition from AFFFs?

Subscribe to the Breaking Down PFAS newsletter to receive breaking news and dispatches from the latest developments in the field: www.cdmsmith.com/PFAS The Department of Defense (DOD) has initiated measures to phase out the use of aqueous film-forming foams (AFFF). It's known to contain per- and polyfluoroalkyl substances (PFAS), and it's ubiquitous in fire suppression systems. How can facilities transition out of using this foam for safer, more biodegradable alternatives that battle blazes? Jill Greene is an environmental expert dedicated to safeguarding our natural resources in the battle against PFAS. With two decades of experience focusing her work on hydrogeologic, stormwater and hazardous waste investigations, Jill reveals key insights on the challenge to transition from AFFF use and the team you'll need to do it.

How do you determine the right level of treatment for PFAS?

How do you determine the right level of treatment for PFAS?

PFAS research is constantly evolving. Subscribe to the Breaking Down PFAS newsletter to receive breaking news and dispatches from the front lines of R&D projects and the latest developments in the field: https://www.cdmsmith.com/en/Client-Solutions/Focus-Areas/PFAS What's the right level of treatment for PFAS? Too little and you risk PFAS getting through. Too much and you could blow up your budget. Dr. Charles Schaefer and his all-star team are diligently designing PFAS treatability studies to address this problem head on. Charles is an environmental scientist and the director of CDM Smith's Bellevue, Washington research and testing lab with a wide array of experience in fate and transport of organic contaminants in soil and bedrock. He's a leading researcher in the treatment of per- and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). The ability to work on innovative and industry-changing research is a key motivator for the research that Charles does.

How should WWTPs manage PFAS in biosolids?

How should WWTPs manage PFAS in biosolids?

Per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals," pose a complex challenge to wastewater treatment facilities. These facilities don't generate PFAS, but they bear the burden of receiving them. New regulations are posing a universal question for WWTPs: how should they manage the biosolids they generate? The more we learn about forever chemicals, the more experts must strategize about treatment, the future of biosolids use, and management costs. Environmental engineer Eric Spargimino explains what this challenge means for wastewater treatment plants. Eric has 15 years of experience in his field, and recently partnered with the Water Environment Foundation (WEF), National Association of Clean Water Agencies (NACWA) and the North East Biosolids and Residual Association (NEBRA) to conduct an in-depth survey of PFAS affected facilities.
