PFAS Q&A: Langan’s PFAS Navigator

What is the first thing clients want to know about PFAS?

Heather Nunn: The first thing clients usually want to know is if there’s PFAS at their site and, if there are, are they above regulatory standards? But answering that question isn’t always straightforward.

PFAS are a large group of synthetic chemicals and known for being very persistent in the environment. Regulations around PFAS are changing very quickly. States are adopting their own guidance, and the federal government is adopting guidance through agencies like the EPA. This patchwork makes it difficult, especially for companies operating across multiple jurisdictions.

That’s why tools like Langan’s PFAS Navigator are so valuable. It’s an interactive map for regulations and allows the user to see current and proposed regulations. It allows us and our clients visualize where their site sits in relation to regulatory standards and helps make informed decisions about sampling, remediation, and reporting.

In a landscape where rules are changing fast, having a dynamic tool like this can be the difference between proactive management and costly surprises.
