Arsenic Known carcinogen found naturally in Arizona groundwater at levels far above health guidelines. | 1.72 ppb | 0.01 ppb | 172x |
Chromium-6 Hexavalent chromium — linked to cancer at trace levels with no enforceable federal standard. | 0.58 ppb | 0.03 ppb | 19x |
Vanadium Toxic metal in groundwater linked to developmental harm. No federal drinking water limit exists. | 5.9 ppb | 0.1 ppb | 59x |
What This Means For You
Chandler's water is legally “safe” according to federal standards — but those standards were last updated decades ago. The EWG sets health guidelines based on the latest science, and Chandler exceeds them on 4 contaminants.
With a hardness level of 17.1 gpg, your water is classified as extremely hard. That means accelerated scale buildup in your pipes, water heater, and appliances. Most water heaters in Chandler lose 25–40% of their efficiency within 5 years from hard water deposits.
Recent: Chandler shares much of its water infrastructure with Mesa, resulting in similar contaminant profiles and very hard water.
