Drinking water systems, on the page as scale and not as buyers
This is the loudest lane in the PFAS market and, on our read, the furthest from you. There are 49,378 active community water systems in the country, 9,619 of them serving more than 3,300 people, and 8,108 of those are owned by a unit of local government. That is genuine scale and it is where the regulatory noise is. But these systems buy engineered treatment for water at a point of entry, and the installed answer is carbon, ion exchange and membranes. It is a different physical problem from breaking down contamination in soil and organic matter. We put the number here so the page is honest about what it is choosing to walk past, not to suggest a route in.
Why the direction of travel matters: the federal drinking water limits finalized in April 2024 covered six PFAS. In May 2026 two proposals went out for public comment, one keeping the limits for the two best known compounds while offering systems an option to take two more years to comply, and one proposing to withdraw the limits for four others. Both are proposals, not settled law. Either way the pull in this lane is toward treating water on a longer clock, not toward new soil chemistry.
