Herriman Water Quality
Is Herriman tap water safe to drink?
Herriman's public water is regulated to meet EPA legal limits. The EPA SDWIS record shows 3 contaminants on file, led by Radium (combined -226 & -228), plus PFAS detected. Local water is very hard. But meeting legal limits isn't the same as zero-risk. Our Water Score rates it 61/100. See the breakdown below, or pull a free water report to learn what's actually coming out of your tap.
What's really in Herriman's water
Radium (combined -226 & -228)
Violation on record
4 EPA records on file (most recent 2023). Radium is a naturally radioactive element that leaches from rock into groundwater. Long-term exposure increases the risk of bone cancer and other cancers because it concentrates in bone. The federal limit covers the combined activity of radium-226 and radium-228.
PFAS (forever chemicals)
Detected
Detected in the supply below the federal limit. PFAS are "forever chemicals" that don't break down and accumulate over time. Compounds found: PFHxA, PFPeA.
Water hardness
very hard
Herriman'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.
Gross Beta / Photon Emitters
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 2 EPA records on file (most recent 2022).
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.
