What's really in Hildale's water
PFAS (forever chemicals)
Violation on record
Detected above the EPA's 4 ppt limit for PFOA/PFOS — the "forever chemicals" linked to cancer and immune effects. Compounds found: PFBS, PFHxA, PFHxS, PFOS, PFPeA, PFPeS.
Gross Beta / Photon Emitters
Detected
Detected below the federal limit. 1 EPA record on file (most recent 2019).
Water hardness
very hard
Hildale's water is very hard. Hardness isn't a health risk, but it drives scale on fixtures and water heaters, shortens appliance life, and leaves skin and hair dry.
Monitoring & reporting notes
EPA records below are administrative or monitoring/reporting compliance items — not measured exceedances of the legal limit. They do not, on their own, mean the water is unsafe.
Total Trihalomethanes (TTHM)
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 1 EPA record on file (most recent 2024).
Haloacetic Acids (HAA5)
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 1 EPA record on file (most recent 2024).
EPA violations may be administrative or monitoring/reporting issues rather than measured exceedances of a health limit. A utility appearing on this list does not by itself mean the water is unsafe to drink. Health-based goals (EPA MCLG / WHO) are health targets and are often stricter than the legal limit (the federal MCL). The only way to know what is in your specific home is to test your own water.
