Is Apple Valley tap water safe to drink?
Apple Valley's public water is regulated to meet EPA legal limits. The EPA SDWIS record shows 4 contaminants on file, led by Radium-226. Local water is very hard. But meeting legal limits isn't the same as zero-risk. Our Water Score rates it 74/100. See the breakdown below, or pull a free water report to learn what's actually coming out of your tap.
What's really in Apple Valley's water
Radium-226
Violation on record
12 EPA records on file (most recent 2025). Radium-226 is a naturally radioactive isotope that seeps from rock into groundwater. Over years of exposure it concentrates in bone and raises the risk of bone and other cancers. It is regulated together with radium-228 under the combined radium standard.
Water hardness
very hard
Apple Valley'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.
Radium (combined -226 & -228)
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 6 EPA records on file (most recent 2022).
Gross Beta / Photon Emitters
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 5 EPA records on file (most recent 2022).
Uranium
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 2 EPA records on file (most recent 2023).
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.
