Welcome to CDM Smith.

Per- and Polyfluoroalkyl Substances (PFAS)

CDM Smith scientists and engineers are taking on one of the biggest cont­a­m­i­na­tion crises of our time—and delivering results.

First applied to consumer goods nearly a century ago, per- and poly­flu­o­roalkyl substances (PFAS) are pervasive, man-made chemicals linked to adverse human health effects. While these compounds have become indis­pens­able building blocks of some of the most common household products, they are extremely versatile, difficult to destroy and bioac­cu­mu­late for long periods of time. As we learn more about potential impacts to human health, it’s important to understand how to treat and remove them from our environment and water sources.

CDM Smith has been on the front lines of researching and treating PFAS since 2007, when we began supporting European clients with groundwater projects. Since then, we’ve matured our practice and have completed hundreds of PFAS projects around the globe. We provide the full spectrum of services related to PFAS work, including sampling and analysis, exposure pathway assessments, risk commu­ni­ca­tions and education, bench/pilot scale testing, full scale design and construc­tion. 

We have 19 active PFAS treata­bil­ity and research projects underway, and we are working with utilities, the federal government and private industry to understand fate and transport, site char­ac­ter­i­za­tions and optimal treatment solutions. At the same time, we are breaking new ground in the evaluation and application of PFAS destruction.

CDM Smith is committed to staying in front of PFAS regulations and is proactively working with clients to develop effective and efficient ways to make their sites and water sources safe.

We are working on optimizing the upstream treatment technology, reducing the downstream waste generation, and then destroying the PFAS.
