A PFAS detection is not a violation. Federal limits (4 ppt for PFOA and PFOS) apply to running annual averages, with compliance required by 2029. In May 2026 EPA proposed extending the PFOA/PFOS deadline to 2031 and removing other PFAS limits; not final as of 2026-10-21.
These are public records for whole systems. Your home's pipes, fixtures and any private well can change what you drink. A certified lab test or a hardness test strip gives you your own numbers. Then use our PFAS and lead filter selector to see which certifications to look for.
None of the 6 largest systems here have a health-based violation in EPA records since October 2021. Metropolitan Utilities District's most recent lead 90th percentile was 12.3 ppb (2023), below the 15 ppb action level. Public records can't guarantee what comes out of your tap, especially with older plumbing, so a home test is the surest check.
Metropolitan Utilities District reports about 9.0 grains per gallon (154 mg/L), which is hard. For a 3-person home at 9 gpg, our softener calculator suggests a 24,000 grain unit as a starting point.
None of the 1 sampled system listed here detected PFAS above EPA's reporting levels in UCMR 5 testing.
Most homes are served by Metropolitan Utilities District or one of the other systems listed on this page, but service areas don't follow county lines. Your water bill names your provider, and its annual Consumer Confidence Report has the full test results.
