High-impact, industry-leading PFAS research. Recently, Water Environment Research has recognized two papers led by Lloyd Winchell, a Brown and Caldwell PFAS expert, among its most influential.
“Per- and Polyfluoroalkyl Substances Thermal Destruction at Water Resource Recovery Facilities: A State of the Science Review” (November 2020) and “Pyrolysis and Gasification at Water Resource Recovery Facilities: Status of the Industry” (March 2022), both published by the Water Environment Federation journal, have earned the following distinctions, respectively:
- WEF Top Cited Article 2020-2021
- Top 10 Most Downloaded Papers 2019-2020
- Top Cited Paper in 2022-2023
- Top 10% Most Downloaded 2022
This research comes at a pivotal time. The EPA has stepped up the pace for PFAS regulations, including the recently finalized Maximum Contaminant Levels (MCLs) for six PFAS in drinking water. Public water systems must monitor for these PFAS and have three years to complete initial monitoring (by mid-2027), followed by ongoing compliance monitoring. More regulatory action is expected across all sectors.
“I’m honored to advance PFAS research critical to keeping our environment safe and communities thriving. It’s important that we provide objective, scientifically-based data to our clients and partners at local, state, and federal agencies. But I could not do this alone. Thanks to our team of co-authors for their tireless effort.”
