Utrecht Finds PFAS in Rainwater at All 14 Monitoring Sites

Early results point to PFAS falling with rain, prompting more tests to judge if the problem persists.

Overview

  • The province published initial lab results from KWR confirming PFAS in captured rainwater at every one of its 14 monitoring locations.
  • KWR screened for 45 common compounds and found eight, with PFBA and TFA at nearly all sites and legacy PFOS variants L_PFOS and V_PFOS also detected.
  • The monitoring points sit mostly in nature areas with light contamination and no clear local source to test whether rainfall is delivering PFAS to soil.
  • Further sampling rounds are underway, and officials expect a fuller report with conclusions and possible recommendations by the end of 2026.
  • Utrecht says it backs national and water-sector efforts to reduce PFAS use and supports calls for a total ban on the chemical group.
