UCMR 6 proposal outlines the next round of national monitoring
EPA announced a proposal to monitor 30 unregulated chemicals, including certain PFAS, pesticides, and solvents. The proposed sampling window is 2028–2030. The proposal was published in the Federal Register on July 1, 2026.
A clearer perspective.The details that matter
What this means.
- The proposed monitoring covers 30 chemicals, with sampling planned for 2028–2030.
- The July 1 proposal is separate from the June 26 announcement and from today’s UCMR 5 records.
The context. This remains a proposal in the sources reviewed. UCMR 6 would be a separate monitoring cycle from the UCMR 5 records currently shown on this site.

EPA’s final PFAS survey data: what the complete results show
UCMR 5 is a one-time monitoring survey. A result at or above a limit is a measurement, not a violation: the PFOA and PFOS limits are enforced on running annual averages from 2029, and EPA has proposed letting eligible systems request more time, to 2031.
