Navigating the next generation of environmental risk

As new materials, chemistries and industrial processes are coming to life, so are unprecedented environmental risks. Per- and polyfluoroalkyl substances (PFAS) and other persistent compounds move through complex pathways across water, soil, air and products.

In order to continue advancing sciences and meet evolving regulations, organizations must understand where these substances occur, what risks they create and how to manage them responsibly.

Our integrated solutions deliver clear, defensible environmental action.
Why it matters

Persistent chemicals are driving higher standards of environmental performance

Standards for PFAS and other persistent chemicals are tightening across drinking water, industrial discharges, biosolids and consumer products. New monitoring requirements, reporting obligations and regulatory scrutiny are expanding quickly, placing environmental performance under greater pressure.

The implications extend well beyond compliance. Organizations must navigate treatment investments, operational adjustments, permitting challenges, and growing exposure to enforcement actions and litigation. Communities, regulators and investors are paying closer attention to how these risks are managed. Responding effectively requires integrated scientific insight, regulatory expertise, and defensible solutions that support confident environmental performance.
