Recent tests are below federal safety limits
Every recently tested contaminant with a clinically reviewed limit is below the level we'd flag for caution.
Risk classification follows EPA's published values for safe drinking water, with caution and concern bands reviewed by a clinician. Past resolved violations do not influence this card. See methodology.
Lead service line inventory
No inventory data on file
We do not yet have this utility's published Lead Service Line Inventory on file. The EPA Lead and Copper Rule Improvements (LCRI) required every community water system to publish one by October 16, 2024 and to identify and replace any lead lines within 10 years. How lead enters drinking water.
Phase 1 coverage focuses on the largest NC utilities. Smaller systems will be added; in the meantime, ask your utility for their inventory or check their Consumer Confidence Report.
Lead and copper test results
The most recent measurement per contaminant from EPA's Lead and Copper Rule sampling.
Why only lead and copper, and not arsenic, nitrate, or others?
EPA's bulk SDWIS download is the only nationwide per-system sample data they publish, and it only includes the Lead and Copper Rule table. Values for other regulated contaminants (TTHMs, nitrate, arsenic, etc.) appear on this page only when they trigger a violation. For the full per-system contaminant suite, see the utility's annual Consumer Confidence Report (link further down the page).
| Contaminant | Most recent | Date | Risk |
|---|---|---|---|
| PB90 | 0 mg/L | December 31, 2025 | Below regulatory thresholds |
Data from EPA SDWIS (Lead and Copper Rule sample table) , last refreshed May 24, 2026.
Fluoride
We don't yet have this utility's specific fluoridation status from CDC's My Water's Fluoride listing. The figures below describe the broader area, not ROARING FORK MHP itself.
Area context
Illinois statewide (2020 data)
- Population on fluoridated water
- 11,457,094 of 11,640,823 (98.4%)
- Community water systems adding fluoride
- 1,639 of 1,815

Compliance history
EPA-recorded violations against this system over the last 5 years.
How to read this section
Health-based violations are when a measured limit was exceeded; the measured concentration is shown alongside the EPA federal limit where SDWIS published it. Monitoring and reporting items are paperwork issues (missed sample dates, late filings) that do not themselves indicate unsafe water.
No health-based violations
No health-based violations on file in the last 5 years. EPA recorded 315 monitoring or reporting items (paperwork) during the same period.

Data from EPA SDWIS (violation records) , last refreshed May 24, 2026.
Where to see every contaminant this utility tested for
EPA's bulk SDWIS dataset gives MyTapWater.us per-system measured values for lead and copper, plus violation records for everything else. To see every regulated contaminant this utility tested for in the past year (TTHMs, HAA5, nitrate, arsenic, fluoride, chromium, etc.) with measured values, read the utility's Consumer Confidence Report (CCR).
Every community water system is required by EPA to publish a CCR annually, by July 1, listing every contaminant they sampled, the measured value, the federal limit, and any health-based exceedances. Most utilities post the report online; some mail it with your bill.
How to find ROARING FORK MHP's CCR:
- Search the web for "ROARING FORK MHP consumer confidence report" . The PDF is usually on the utility's own website.
- Or call the utility directly. Their phone number is in the contact section below.
