PFAS
Per- and polyfluoroalkyl substances (PFAS), a very large and resilient family of chemicals with unique properties, poses one of the greatest challenges in water treatment and environmental remediation in decades. We're ready for the fight.
With experience on more than 170 PFAS investigations and treatment projects across the globe, our team of environmental engineers and scientists has an unparalleled understanding of these pervasive chemicals. We work closely with our clients, our R&D partners and our laboratory team to meet regulatory guidelines and spark scientific breakthroughs in site characterization, fate and transport and treatment.
Partner with us to deploy the brightest minds in engineering and we will keep you operating ahead of the curve.


The future of PFAS is about options: optimizing upstream treatment technology, reducing downstream waste generation, and destroying PFAS.
