Environmental Justice Note: On average, 58% of census tracts in the counties mapped to this service area are designated disadvantaged by the federal Climate and Economic Justice Screening Tool (CEJST, 2022 version). Communities with higher disadvantaged populations often face disproportionate environmental and health burdens, including aging water infrastructure and limited resources for remediation.

๐Ÿ’ง Where Does Your Water Come From?

Groundwater

North Mohave Valley's water is classified in EPA records as a groundwater source. Groundwater is naturally filtered through rock and soil, but it can be vulnerable to PFAS contamination, nitrates from agriculture, and industrial chemicals that seep into the water table.

PFAS in ZIP Codes This System Serves

PFAS ("forever chemicals") have been reported in samples from water systems associated with the ZIP codes in this system's area. These results can come from other water systems serving the same ZIP codes; check the UCMR5 section for any results reported for this system. 5 detections recorded. 1 detection is above the level of a federal PFAS MCL (4 ppt for PFOA and PFOS), with compliance required from 2029.

Health concern: Exposure to certain PFAS has been associated with some cancers and with immune and developmental effects; effects differ by compound. Many PFAS break down very slowly in the environment.
Recommended filter: An activated carbon filter certified under NSF/ANSI 53 or a reverse osmosis system certified under NSF/ANSI 58 for the PFAS listed in its certification. Find the right filter โ†’

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 2026-12-31
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

1 of 1 ZIP records with known zones is in EPA Radon Zone 2.

The EPA recommends testing all homes regardless of radon zone. County radon zones cannot replace an in-home radon test.

ZIP Codes Served

Coverage: Service area ZIP codes sourced from EPA Community Water System Service Area Boundaries v3 (March 2026 release). These ZIPs reflect the actual deployment footprint recorded by AZ or modeled from parcel and building-footprint data.

Where does North Mohave Valley get its water?

The primary water source is groundwater.

Federal UCMR5 PFAS Monitoring: Sample Above an EPA MCL Value or State Standard

This water system was tested under the federal EPA Unregulated Contaminant Monitoring Rule (UCMR5). One or more PFAS measurements were above the level of the EPA MCL for that compound (April 2024 rule, which takes effect in 2029) or above an applicable state drinking-water standard; a monitoring result above that level is not by itself a violation.

EPA's April 2024 PFAS rule sets MCLs of 4 ppt for PFOA and PFOS and 10 ppt for PFHxS, PFNA and HFPO-DA (GenX); water systems must comply from 2029. Other PFAS compounds have no individual federal MCL. A state standard is shown only where this system's state has its own enforceable PFAS limit. Detection results are EPA UCMR5 samples, not a measurement at your tap.

How many people does North Mohave Valley serve? ▼
North Mohave Valley serves approximately 5,190 people with drinking water across 1 ZIP code.
What is North Mohave Valley's water source? ▼
North Mohave Valley draws water from groundwater sources. Source type affects which contaminants are most likely to be present.
Is there lead in North Mohave Valley's water? ▼
The most recent 90th-percentile lead result on record is 0.022 mg/L (sample period ending 2026-12-31). This exceeds the EPA action level of 0.015 mg/L. A lead-certified filter is recommended, especially for homes with young children.
What is the demographic profile of the ZIP codes associated with North Mohave Valley? ▼
The ZIP codes mapped to North Mohave Valley have a median household income of $53,113 (Census ZIP-code estimate).
