https://www.tapwaterlookup.com/news/Dated U.S. drinking-water announcements explained with original official sources. This is not an emergency alert service.en-usSun, 27 Sep 2026 12:00:00 GMThttps://www.tapwaterlookup.com/news/final-ucmr5-pfas-results/https://www.tapwaterlookup.com/news/final-ucmr5-pfas-results/Sun, 27 Sep 2026 12:00:00 GMTEPA announcement: 2026-08-28. EPA has published the final dataset from its fifth Unregulated Contaminant Monitoring Rule (UCMR 5), the national survey of 29 PFAS and lithium in public drinking water. The final file holds 1,992,002 results from 10,313 water systems, with samples collected from January 2023 to June 2026. 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.PFAShttps://www.tapwaterlookup.com/news/broader-drinking-water-study/https://www.tapwaterlookup.com/news/broader-drinking-water-study/Tue, 15 Sep 2026 12:00:00 GMTEPA announcement: 2026-09-09. A new EPA study will use non-targeted analysis to look for potential pollutants beyond the chemicals covered by routine tests. The research will screen for pharmaceuticals, PFAS, and other substances to help identify future research priorities. This is a study announcement. It does not report a finding about your local water supply or establish a new drinking-water limit.Monitoringhttps://www.tapwaterlookup.com/news/lead-service-line-guidance/https://www.tapwaterlookup.com/news/lead-service-line-guidance/Tue, 15 Sep 2026 12:00:00 GMTEPA announcement: 2026-08-21. EPA published two practical resources for water systems: one about accessing properties for service-line work, and another about maintaining service-line inventories. The documents support implementation of the Lead and Copper Rule Improvements. These are guidance documents explaining existing requirements. The announcement does not mean that a particular home has a lead service line.Leadhttps://www.tapwaterlookup.com/news/small-system-technical-assistance/https://www.tapwaterlookup.com/news/small-system-technical-assistance/Tue, 15 Sep 2026 12:00:00 GMTEPA announcement: 2026-07-24. EPA announced grant funding for organizations that help small and rural water systems manage operations, finances, and infrastructure. The planned assistance also includes support for private wells and wastewater systems. The announcement says awards depend on legal and administrative requirements. It is funding for assistance providers, rather than a household rebate application.Fundinghttps://www.tapwaterlookup.com/news/ucmr6-monitoring-proposal/https://www.tapwaterlookup.com/news/ucmr6-monitoring-proposal/Tue, 15 Sep 2026 12:00:00 GMTEPA announcement: 2026-06-26. 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. 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.Monitoringhttps://www.tapwaterlookup.com/news/pfas-drinking-water-proposals/https://www.tapwaterlookup.com/news/pfas-drinking-water-proposals/Tue, 15 Sep 2026 12:00:00 GMTEPA announcement: 2026-05-18. One proposal would let eligible systems request additional time, through 2031, to meet PFOA and PFOS limits. A separate proposal would rescind the regulations for PFHxS, PFNA, HFPO-DA, and specified PFAS mixtures. Both are identified as proposals in the EPA pages reviewed. An extension would require a request and approval; it is not an automatic deadline change for every utility. Their public comment periods closed July 20, 2026.PFAS
