Cities ranked by the records

Showing 3 of 3 cities · scores are system-level, not tap tests

Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no county score. The score is computed only from contaminants measured in the published EPA record, so this ranks the record, not which city's water is safest. How the score works.

Questions

Frequently asked

How does Harnett County tap water compare across cities?

PurityMap ranks 3 cities in Harnett County by the Purity Score of each city's main water system, computed only from contaminants measured in the published EPA record. Scores belong to water systems, not to cities. The highest published score is Fuquay-Varina's main water system: FUQUAY-VARINA, TOWN OF · PWSID NC0392055 · Purity Score 56 (Fair) · Confidence: moderate · Assessed at the water-system level. The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.

How many Harnett County cities had a PFAS sample above a 2024 EPA limit?

3 of 3 Harnett County city reports had a PFAS sample above a 2024 EPA limit in EPA's UCMR 5 testing, including Spring Lake (PFOS 15.6 ng/L), Angier (PFOS 13.5 ng/L), Fuquay-Varina (PFOA 11 ng/L). That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation. PFAS were detected at any level in 3.

Is there lead in Harnett County tap water?

Utilities report lead as a 90th-percentile result from home taps. 0 of 3 Harnett County cities reported a value above zero, and none was above the 15 µg/L federal action level. Lead usually comes from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

Have Harnett County water systems had drinking-water violations?

2 cities in Harnett County have a health-based violation in the federal SDWIS record within about the last ten years. Each city report lists the contaminant, year and whether it was resolved.
