System Overview

North Chicago (EPA ID: IL0971250) is a community water system in Illinois that serves approximately 16,813 people from surface water sources.

This system provides water to 4 ZIP codes across 4 communities.

ZIP-Area Home Safety Context: B (77/100)

This is the average Home Safety Score for 2 of 4 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

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

Status breakdown for accepted records with record years 2021-2026: 5 resolved, 0 archived, 0 addressed, and 1 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 Level Exceeds Action Level Sample Date
Below the reporting limit No 2026-06-30

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

4 of 4 ZIP records with known zones are 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.

Frequently Asked Questions

Is North Chicago water safe to drink?

The accepted 2026Q2 ECHO snapshot shows 1 current noncompliance record and zero current records classified as health-based. That classification is not a property-specific water test or safety guarantee.

How many people does North Chicago serve?

Where does North Chicago get its water?

The primary water source is surface water.

Federal UCMR5 PFAS Monitoring: No PFAS Reported Above Reporting Levels

This water system was tested under the federal EPA Unregulated Contaminant Monitoring Rule (UCMR5). No PFAS compounds were reported above UCMR5 minimum reporting levels.

Samples collected
116

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.
