๐Ÿ’ง Where Does Your Water Come From?

Groundwater

Normal'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. 6 detections recorded.

State PFAS values in our reference data (health advisory / health-based guidance value (not a limit)); check current state rules: PFHxA: 1900 ppt, PFBA: 3800 ppt
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

Normal (EPA ID: IL1130900) is a community water system in Illinois that serves approximately 52,736 people from groundwater sources.

This system provides water to 6 ZIP codes across 4 communities.

ZIP-Area Home Safety Context: C (67/100)

This is the average Home Safety Score for 3 of 6 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

No accepted violation records in the 2021-2026 window - The accepted EPA ECHO 2026Q2 snapshot contains zero violation records for this system whose record year falls from 2021 through 2026, inclusive. This is not a tap-water safety guarantee.

Lead & Copper

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

Lead Level Exceeds Action Level Sample Date
0.0055 mg/L No 2025-12-31

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

6 of 6 ZIP records with known zones are in EPA Radon Zone 1.

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 IL or modeled from parcel and building-footprint data.

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
58

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.
