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).

Most recent measurements per contaminant (Lead and Copper Rule) . Sorted by risk: concern first, then caution, then unrated, then safe.
Contaminant	Most recent	Date	Risk
Lead 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.

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.
