Tonopah Water Quality
What's in Tonopah's water
Arsenic
Violation on record
11 EPA violations on record (most recent 2017). Arsenic is a naturally occurring element that dissolves into groundwater from rock and is also released by mining and industry. Long-term exposure is associated with several cancers and with skin, cardiovascular, and developmental harm. It is common in parts of the Southwest.
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.
