Current water quality
Current measurements are below regulatory thresholds
Lead measured at 0 mg/L in the most recent sample (below regulatory thresholds).
Past 5 years: 8 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
Utility reports no confirmed lead service lines
The Town of Cary concludes with 95 percent statistical confidence that there are no lead service lines in the system. Cary operates approximately 75,000 water service connections; most were installed after the late-1980s federal lead ban.
- 0 confirmed lead service lines
- 75,000 total service lines in the system
Note: Cary used desktop analysis plus field verification (BlueConduit predictive modeling, Esri LSLI tooling) on ~6,800 initially-unknown connections.
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 120 times across UCMR 5; 4 of those substances were detected in at least one sample. Most-recent detection per contaminant shown below.
| Contaminant | Most recent detection | Date | Risk |
|---|---|---|---|
| 5.8 ng/L | November 4, 2025 | No federal limit EPA has not set a federal drinking-water limit for this contaminant. It is among the substances EPA is studying under the Unregulated Contaminant Monitoring Rule (UCMR). See the guide for what the science currently says. Learn more about PFBA. | |
| 3 ng/L | November 4, 2025 | No federal limit EPA has not set a federal drinking-water limit for this contaminant. It is among the substances EPA is studying under the Unregulated Contaminant Monitoring Rule (UCMR). See the guide for what the science currently says. Learn more about PFBS. | |
| 5.4 ng/L | November 4, 2025 | No federal limit EPA has not set a federal drinking-water limit for this contaminant. It is among the substances EPA is studying under the Unregulated Contaminant Monitoring Rule (UCMR). See the guide for what the science currently says. Learn more about PFHxA. | |
| 5.7 ng/L | November 4, 2025 | No federal limit EPA has not set a federal drinking-water limit for this contaminant. It is among the substances EPA is studying under the Unregulated Contaminant Monitoring Rule (UCMR). See the guide for what the science currently says. Learn more about PFPeA. |
Tested but not detected (26 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.
8 resolved health-based violations in the last 5 years
All 8 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 CARY, TOWN OF's CCR:
