Grade C — based on EPA compliance records, lead testing and PFAS monitoring
CITY OF AUSTIN WATER & WASTEWATER has a mixed record — read the reasons below; the deductions come from real EPA violations, lead results or PFAS detections, not from a template.
Austin, TX tap water is legal to drink but grades C on EPA's records, mainly because of 1 health-based EPA violation in the last five years and PFOA or PFOS measured at or above the 4 ppt federal limit in 2023–2025 EPA sampling. A certified filter matched to those findings is a reasonable precaution.

CITY OF AUSTIN WATER & WASTEWATER's most recent Lead and Copper Rule result (2022-01-01 to 2024-12-31) was 0 ppb at the 90th percentile, below EPA's 15 ppb action level. Because lead usually comes from service lines and household plumbing, homes built before 1986 should still test at the tap.
Yes. EPA's UCMR5 sampling (2023-10-02 to 2024-07-30) detected PFBA, PFBS, PFHxA, PFHxS, PFOS, PFPeA, with PFOA or PFOS at or above the 4 ppt federal MCL. Reverse osmosis and certified activated-carbon filters reduce PFAS.
CITY OF AUSTIN WATER & WASTEWATER has 5 violations on file since 2016: 1 health-based in the last five years and 0 monitoring or reporting violations in that window. Monitoring violations are paperwork lapses, not measured contamination.
CITY OF AUSTIN WATER & WASTEWATER reports surface water as its primary source and serves about 1,115,323 people (EPA PWSID TX2270001).
We recommend one. Reverse osmosis or a PFAS-certified carbon filter addresses the PFAS result.
