What's really in Wickenburg's water
Nitrate
Violation on record
3 EPA records on file (most recent 2023). Nitrate enters water mainly from fertilizer runoff, septic systems, and animal waste. High levels can interfere with the blood's ability to carry oxygen, a special danger for infants. Long-term low-level exposure has also been linked to elevated cancer risk in some studies.
Water hardness
very hard
Wickenburg'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. 1 EPA record on file (most recent 2023).
Total Trihalomethanes (TTHM)
Monitoring / reporting note
Monitoring / reporting compliance note — not a measured exceedance. 1 EPA record 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.
