Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no state 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.

How does South Carolina tap water compare across cities?

PurityMap ranks 71 cities in South Carolina 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 Greenville (sc2310001)'s main water system: GREENVILLE WATER (SC2310001) · PWSID SC2310001 · Purity Score 100 (Excellent) · 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 South Carolina cities have PFAS above the federal limit?

35 cities of 71 had at least one regulated PFAS (PFOA, PFOS or PFHxS) measured above the 2024 federal limit in EPA's UCMR 5 testing, including Laurens County W S Comm (sc3020001) (HFPO-DA (GenX) 95.8 ng/L), Greenwood Cpw (HFPO-DA (GenX) 91.1 ng/L), Winnsboro (PFOS 32.8 ng/L). PFAS were detected at any level in 51.

Is there lead in South Carolina tap water?

Utilities report lead as a 90th-percentile result from home taps. 48 of 71 South Carolina 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 South Carolina water systems had drinking-water violations?

5 cities in South Carolina 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.

Limits, sources and corrections

A statewide page cannot tell you what reaches a specific address. Water quality varies by supplier, sampling period and household plumbing; open a city report for the evidence behind a local result.

Sources: EPA UCMR 5 (PFAS, 2024), SDWIS Lead and Copper Rule 90th-percentile results and health-based violations, and utility Consumer Confidence Reports where on file. Every city report links its dated source records.
