Current water quality
Caution: a recent measurement is approaching a regulatory limit
Lead measured at 0.003 mg/L in the most recent sample (caution).
Past 5 years: 4 health-based violations on file, all marked Resolved or Archived. See compliance history below.
Risk classification follows EPA published MCL / MCLG / HAL values with caution and concern bands reviewed by a clinician. Past resolved violations do not influence this badge. 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 Rule sample data
The most recent measurement per contaminant from EPA's Lead and Copper Rule (LCR) sample table. This is the only per-system sample data EPA publishes in the bulk SDWIS download; values for other regulated contaminants (TTHMs, nitrate, arsenic, etc.) are tracked on this page only when they trigger a violation.
| Contaminant | Most recent | Date | Risk |
|---|---|---|---|
| PB90 | 0.003 mg/L | December 31, 2025 | Caution Lead has no safe level (MCLG=0). LCR action level is 0.015 mg/L for the 90th-percentile sample; the LCRI (Oct 2024) lowers the action level to 0.010 mg/L effective Nov 2027. Caution at any detection above LOD; concern anchored to the future LCRI value (0.010 mg/L) for forward consistency. Learn more about Lead. Source. |
Recorded contaminant measurements (from violations)
When this system exceeded a regulatory limit and EPA recorded the measured value, that value is shown here. These are not routine sample results: they are the values the violation was triggered on.
| Period | Contaminant | Measured | Federal MCL | Status |
|---|---|---|---|---|
| October 1, 2025 | Combined Uranium | 55PCI/L | — | Health-based |
| October 1, 2025 | Gross Alpha, Excl. Radon and U | 356PCI/L | — | Health-based |
Compliance history
EPA-recorded violations against this system over the last 5 years. Health-based violations are when a measured limit was exceeded; monitoring and reporting items are paperwork issues (missed sample dates, late filings) that do not themselves indicate unsafe water.
4 resolved health-based violations in the last 5 years
All 4 health-based violations in the last 5 years are marked Resolved or Archived. Past violations do not represent current water quality.

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 ROCKBRIDGE S/D's CCR:
-
Search
"ROCKBRIDGE S/D consumer confidence report"in your browser. The PDF is usually on the utility's own website. - Or check EPA's CCR finder for NC4092073 (some utilities upload theirs to EPA, some do not).
- Or call the utility directly. Their phone number is in the contact section below.
