Why chromium-6 Matters
Chromium-6 (hexavalent chromium) is classified as a known human carcinogen when inhaled and a likely carcinogen in drinking water. California set a public health goal of 0.02 ppb, though the federal EPA has no standard.
This is especially important for families with young children, pregnant women, or anyone with a compromised immune system. Children absorb contaminants at higher rates than adults, and their developing bodies are more vulnerable to the effects.
Check Your Specific Address
Water quality can vary within Phoenix depending on which part of the distribution system serves your home, the age of your pipes, and whether you have lead service lines. I recommend two steps:
- Use our free Water Quality Lookup tool - Enter your ZIP code here to check EPA violation records for your specific area.
- Test your tap water - A home water test kit like Tap Score ($150-200) will tell you exactly what's in the water coming out of your faucet, which can be different from what the utility reports.
