What's really in Kingman's water
Radium-226
Violation on record
43 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.
Uranium
Violation on record
31 EPA records on file (most recent 2025). Uranium occurs naturally in rock and dissolves into groundwater, with extra contributions from mining in some regions. It is both a radioactive and a toxic metal; long-term exposure mainly damages the kidneys and increases cancer risk. It is widespread in Western groundwater.
Arsenic
Detected
Detected below the federal limit. 47 EPA records on file (most recent 2025).
Gross Beta / Photon Emitters
Detected
Detected below the federal limit. 28 EPA records on file (most recent 2017).
Water hardness
very hard
Kingman'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.
Haloacetic Acids (HAA5)
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 5 EPA records on file (most recent 2025).
Total Trihalomethanes (TTHM)
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 5 EPA records on file (most recent 2025).
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.
