Short answer: In the 2023–2026 records we hold for Warrior River, two PFAS, PFOA and PFOS, each had a sample above a 2024 EPA limit (not a violation: the limits are judged on a yearly average, due 2029), and a health-based violation is on record (EPA SDWIS). Also worth knowing: lithium sits above a screening level. 6 substances were detected and 25 were tested and not detected. The water is from Warrior River Water Authority, serving 38,700 residents.

Two PFAS, PFOA and PFOS, each had a sample above a 2024 EPA limit (not a violation: the limits are judged on a yearly average, due 2029); lithium sits above a screening level.
5.7 ng/L, sampled 2023-12-05 to 2024-09-30. EPA UCMR 5.
4.0 ng/L federal MCL (2024): a legal limit. That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation. EPA health goal (MCLG): 0.
One EPA sample measured 5.7 ng/L, above the 4 ng/L limit EPA set in 2024. That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation.

Older buildings may have lead service lines, solder or fixtures. Lead is not in Warrior River’s published record, so only a tap test tells you. Test first-draw water, then filter if needed.
5 of 29 PFAS tested were detected in Warrior River’s record (PFOS 5.7 ng/L, PFOA 4.2 ng/L and PFBS 3 ng/L, and more); 2 above their limit. If PFAS matters to you, a filter certification names each compound it covers.
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
Your utility’s annual water quality report usually lists hardness; a test strip also measures it.
Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.
Get one email when Warrior River’s record changes.
One email when a new sampling round is published, a result moves above or below its reference, or the system's score changes.PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Warrior River, PFOS 5.7 ng/L and PFOA 4.2 ng/L were measured in one EPA sample each, above the 4 ng/L limit EPA set in 2024 (not a violation: the limits are judged on a yearly average, due 2029). WARRIOR RIVER WATER AUTHORITY (PWSID AL0000763) has a Purity Score of 67/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap. What we found →

Yes. In EPA's UCMR 5 testing (2023-12-05 to 2024-09-30), PFOS was measured at 5.7 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024 and PFOA was measured at 4.2 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024. EPA's 2024 limits are judged on a yearly average, and water systems have until 2029 to meet them, so a single sample is not a violation. PFBS (3 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (4.7 ng/L, below the 400,000 ng/L state limit) were also detected. PFPeA (6 ng/L) was also detected; it has no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap. What we found →
Lead is not in Warrior River's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours. Your household →

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
EPA SDWIS, EPA UCMR 5 and utility reports, each dated and linked.
Units converted to one basis; a non-detect kept distinct from zero.
Each result tagged by reference type: MCL, action level, screening level or aesthetic.
Every value sits against its own reference, never a blended one.
Measured subjects summarised at the water-system level; an open health-based violation caps the score.
Treatment is matched to what was found; a product is called certified only when its current certification names it.
What the Purity Score means: a summary of this water system’s published record, capped while a health-based violation is open. It is not a test of any tap. WARRIOR RIVER WATER AUTHORITY · PWSID AL0000763 · Purity Score 67/100 (Fair) · Confidence: moderate · Assessed at the water-system level
