Water hardness

very hard

Tonopah'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.

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.
