HARNETT REGIONAL WATER | LILLINGTON, NC water quality

Current water quality

Concern: current measurement or unresolved violation crosses a regulatory limit

PFOA measured at 7.7 ng/L via UCMR 5 sampling (concern).

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

Harnett Regional Water reports no lead service lines have been identified in its distribution system to date. An inventory spreadsheet was published on October 15, 2024.

0 confirmed lead service lines

Note: Inventory file is a 6.2 MB PDF of per-address line items; tabular category counts are not extractable from the page text.

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.

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.

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; 7 of those substances were detected in at least one sample. Most-recent detection per contaminant shown below.

Most recent UCMR 5 detection per contaminant . Sorted by risk: concern first, then caution, then unrated, then safe.
Contaminant	Most recent detection	Date	Risk
PFOA	7.7 ng/L	September 9, 2025	Concern April 2024 final rule. MCLG=0. Caution at typical lab reporting limit (0.5 ng/L); concern at EPA MCL (4 ppt), the most conservative federal/state value. Learn more about PFOA. Source.
PFOS	12.3 ng/L	September 9, 2025	Concern April 2024 final rule. MCLG=0. Caution at typical lab reporting limit (0.5 ng/L); concern at EPA MCL (4 ppt). Learn more about PFOS. Source.
PFHxS	3.1 ng/L	September 9, 2025	Caution April 2024 final rule. EPA 10 ng/L MCL is contested 2025 to 2026 (pending rescission as of May 2025); value retained pending spring 2026 rulemaking. Learn more about PFHxS. Source.
PFBS	3.4 ng/L	September 9, 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.
PFHpA	3.3 ng/L	September 9, 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 PFHpA.
PFHxA	6.3 ng/L	September 9, 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.
PFPeA	6.9 ng/L	September 9, 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 (23 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.

Clean record

No violations on file for this system in the last 5 years.

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 HARNETT REGIONAL WATER's CCR:

Search "HARNETT REGIONAL WATER consumer confidence report" in your browser. The PDF is usually on the utility's own website.
Or check EPA's CCR finder for NC0343045 (some utilities upload theirs to EPA, some do not).
Or call the utility directly. Their phone number is in the contact section below.
