Heber, AZ — Water Quality Report
Heber's drinking water received a grade of F (38.2 out of 100), indicating failing water quality. The city's 6 water systems serve approximately 17,473 residents using groundwater.
Lead levels were measured at 11.0 ppb (90th percentile), which is within EPA limits but above recommended levels. PFAS testing under UCMR 5 found no detectable forever chemicals.
The system has 418 violations on record, including 11 health-based violations. 89 remain unresolved.
What to know about Heber's water
Heber ranks #283 out of 292 cities in Arizona for water quality, placing it among the lowest-rated in the state.
Heber relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.
Hexavalent chromium (chromium-6) was detected at 1.30 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.
While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.
The system has seen 55 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

What Heber residents can do
Recommended: NSF-certified water filter. This addresses the specific contaminants found in Heber's water.
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.
Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.
Heber's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.
