Nature-based solutions are succeeding against PFAS contamination at the town of Alpena in the US state of Michigan – where site-specific constraints meant that traditional methods such as pump-and-treat of contaminated water were impractical.

Protecting public health through innovative groundwater treatment.

An $850 million settlement was reached in the first-ever Natural Resource Damage Claim for PFAS in the United States.

Characterizing and remediating the PFAS impacts associated with the historical and current firefighting training facilities.

California regulatory agency, the State Water Resources Control Board (SWRCB), wanted to get a better understanding of PFAS contamination in the state.

PFAS air emissions have led to investigations of soil, groundwater, stormwater, surface water sediment, and fish tissue at an active manufacturing facility in North America.

Desktop screening and ranking of approx.100 airports to prioritize future PFAS investigations related to impacts from Firefighting Training Areas.

This case study details the environmental studies conducted following the spill of a highly concentrated foaming liquid containing Per- and Polyfluoroalkyl Substances (PFAS) that was accidentally released into an ephemeral creek after entering a stormwater drain. 

Quantitative Human Health and Ecological Risk Assessment (Site Specific Risk Assessment or SSRA) to assess the potential risk of PFAS in the environment.

This project illustrates several success factors in PFAS analysis and mitigation, particularly the value of having a three-dimensional conceptual site model to determine the pathways and receptors, and to provide information for choosing mitigation methods.
