Current water quality
Current measurements are below regulatory thresholds
Lead measured at 0 mg/L in the most recent sample (below regulatory thresholds).
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
Service line inventory still in progress
WSFC Utilities has nearly 160,000 private service lines. About 3,800 customers (less than 3 percent) received notification letters for service lines classified as Lead, Galvanized Requiring Replacement, or Unknown. The remaining roughly 97 percent are classified non-lead; fewer than 2 percent remain Unknown post-inventory.
- 160,000 total service lines in the system
Note: Utility reports the combined Lead+GRR+Unknown subset (~3,800) but does not itemize the three categories publicly. We mark inventory_status as incomplete pending category breakdown.
What to do if your service line might be lead
- Ask your utility to check the service-line classification for your specific address. Many utilities provide a public address-lookup tool linked from the inventory page.
- Get on the replacement queue. Under the LCRI, utilities must replace all lead and galvanized-requiring- replacement lines within 10 years (clock generally starts November 2027). Some prioritize requests.
- Until the line is replaced: flush the tap 30 seconds after long stagnation, use cold water for drinking and cooking, and consider an NSF/ANSI 53 lead-rated tap filter.
- Talk to your clinician about a blood lead test for anyone in the home, especially a pregnant person or a child under 6. Lead in drinking water guide.

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 mg/L | December 31, 2025 | Below regulatory thresholds 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. |
PFAS and emerging contaminants (UCMR 5)
EPA's fifth Unregulated Contaminant Monitoring Rule cycle (2023; 2025) tested every public water system serving over 3,300 people for 29 per- and polyfluoroalkyl substances (PFAS) and lithium. This system was tested 360 times across UCMR 5; 0 of those substances were detected in at least one sample. Most-recent detection per contaminant shown below.
No detections
All UCMR 5 samples for this system were below the EPA-defined minimum reporting level (MRL) for every tested contaminant. Substances that were tested but not detected are listed below.
Tested but not detected (30 contaminants)
EPA tested for these substances and every sample was below the minimum reporting level. Absence of detection does not mean true zero; it means below the laboratory's quantitation threshold.
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.
No health-based violations
No health-based violations on file in the last 5 years. EPA recorded 5 monitoring or reporting items (paperwork) during the same period.

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 WINSTON-SALEM, CITY OF's CCR:
