Per- and Polyfluoroalkyl Substances (PFAS)

Dr. Erik Rosenfeldt is Hazen’s Drinking Water Practice Lead and a senior member of the firm’s Reuse and Applied Research groups.

Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals commonly found in the soil, water, and air. Though water treatment facilities do not manufacture PFAS, they will soon be forced into responsibility for PFAS management in drinking water, wastewater effluent, and solid by-products of the treatment process.

Successful PFAS Management

The future of PFAS management includes a lot of uncertainty, such as evolving research on health effects, regulatory changes, and an upcoming national monitoring study. Hazen stands at the forefront of PFAS management, working with clients to develop customized and optimized solutions that provide near-term PFAS water quality improvement and long-term sustainability and certainty.
