System Overview

North Mohave Valley (EPA ID: AZ0408068) is a community water system in Arizona that serves approximately 5,190 people from groundwater sources.

This system serves ZIP code 86429 in Bullhead City.

ZIP-Area Home Safety Context: D (50/100)

This is the average Home Safety Score for 1 of 1 service-area ZIP codes with all required score domains observed. It is not a grade for the water utility.

Model 4.0.0 uses SDWIS identity plus accepted ECHO SDWA lifecycle-based water compliance, the UCMR 5 PFAS MCL screen, EPA radon zone, and annual EPA AirData AQI across three equally weighted domains. Missing required evidence suppresses the score.

Violation History

2 current noncompliance records in the accepted 2026Q2 snapshot; none are classified as health-based in this evidence.

Status breakdown for accepted records with record years 2021-2026: 35 resolved, 0 archived, 0 addressed, and 2 unaddressed. Under this source contract, current noncompliance is the sum of addressed and unaddressed records. Archived and resolved records are excluded from current noncompliance.

Lead & Copper

EPA Lead and Copper Rule evidence attributed directly to this water system:

Lead Level Exceeds Action Level Sample Date
0.022 mg/L Yes N/A
Lead exceeds EPA action level in at least one sampling location. Consider using a certified NSF/ANSI 53 or NSF/ANSI 58 filter rated for lead removal.

No copper action-level exceedance record appears for this PWSID in the accepted LCR snapshot. This does not establish a clean copper measurement.

Radon Risk in Service Area

Dominant radon zone for ZIP codes served by this system: Zone 2 (Moderate Risk)

The EPA recommends testing homes in Zone 1 and Zone 2 areas for radon.
