PFAS in South Carolina tap water

In EPA's 2024 UCMR 5 testing, 35 cities of 73 had a regulated PFAS (PFOA, PFOS or PFHxS) above the new federal limit, and PFAS were detected at any level in 36.

Lead in South Carolina tap water

Utilities report lead as the 90th-percentile result from sampled home taps. 50 of 73 South Carolina cities reported a value above zero, and 0 cities were above the 15 µg/L federal action level. Lead usually enters water from a building's own pipes, so a test at your tap is the only way to know what you drink.

Frequently asked questions

How does South Carolina tap water compare across cities?

PurityMap ranks 73 cities in South Carolina by their Purity Score, computed only from contaminants measured in the published EPA record. Greenville (sc2310001) has the highest published score (100/100). 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 73 had at least one regulated PFAS (PFOA, PFOS or PFHxS) measured above the 2024 federal limit in EPA's UCMR 5 testing, including Winnsboro (PFOS 32.8 ng/L), Gaffney Bpw (sc1110001) (PFOA 18 ng/L), Gsw Sa (sc2620004) (PFOS 11.5 ng/L). PFAS were detected at any level in 36.

Is there lead in South Carolina tap water?

Utilities report lead as a 90th-percentile result from home taps. 50 of 73 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.
