If you are relocating to South Carolina, reconsidering the water after years on the same tap, or you came looking for the old environmental department and found a renamed one, the agency behind the figures below is the South Carolina Department of Environmental Services and its Bureau of Water. It tracks PFAS in the state's public systems, and the numbers below come from federal monitoring rather than any single utility. None of it is a verdict on a particular home. It is the public record, set out so you can read it calmly and decide what is worth reviewing when evaluating an address.
EPA's UCMR 5 program (2021–2024) tested 48 public water systems in South Carolina for 29 PFAS compounds; 24 reported at least one detection and none exceeded the 2024 federal limit of 4 ppt for PFOA/PFOS (a 50% detection rate). Detections vary by water system — check the utility serving a specific South Carolina address.
PFAS oversight in South Carolina now sits with the South Carolina Department of Environmental Services (SCDES), the agency that took on environmental duties after the state reorganized its longtime combined health-and-environment department. Its drinking-water work runs through the Bureau of Water. South Carolina tends to follow the federal framework rather than enforce a stricter standard of its own, so for most residents the operative rule is the April 2024 federal limit SCDES administers: 4 parts per trillion for PFOA and PFOS, and 10 for PFHxS, PFNA, and GenX. If the agency name looks new, that is because it is; the comfort is that the office responsible is clearly named and accountable.
Numbers below come straight from EPA UCMR 5 monitoring (2021–2024). Every public water system in South Carolinaserving more than 3,300 people had to test for 29 different PFAS — here's what they reported.

Red triangles are military installations the Department of Defense has flagged for PFAS from firefighting foam. Orange dots are industrial facilities that reported PFAS to the EPA Toxics Release Inventory. If your future home sits near a cluster, that's a conversation worth having with the seller or landlord.
These are the South Carolinautilities where EPA testing found PFAS the most often or at the highest levels. Being on this list doesn't automatically mean today's tap water is unsafe — some systems have added treatment since these samples were taken — but it means a conversation with the utility is worth having before you move in.

PFAS isn't one chemical — it's a family of thousands. Here are the specific compounds EPA picked up most often across South Carolina water systems. PFOA and PFOS are the two with the strictest federal limits (4 parts per trillion).
For decades the military trained with AFFF firefighting foam loaded with PFAS. It soaked into soil and groundwater and, in many places, traveled miles. If you're house-hunting near any of these South Carolina installations, the address report will tell you exactly how close.

Looking at a specific South Carolinacity? Each page below pulls the same federal data narrowed to that water system — useful whether you're relocating, buying, organizing your neighborhood around getting cleaner water, or just trying to find out what's in the tap and what's around you.
Here is how to read the numbers above without letting them harden into more than they are. The federal monitoring round behind them looked at 29 PFAS compounds at public systems serving more than about 3,300 people, sampled between 2021 and 2024. The gaps matter: private wells were never required to test, smaller rural systems fall below the threshold, and a 2022 detection is a snapshot rather than a promise about today's tap. For a private well, guidance from South Carolina's environmental agency is a better first stop than any statewide system figure. The state recently retired its old combined-department acronym for a fresh one (SCDES), which is its own quiet reminder that agency alphabets rarely stay still.
Military and aviation sites carry their own weight, and South Carolina has a deep, long-standing military presence. For decades, a firefighting foam called AFFF was used in training at such sites, and it contained the PFAS compounds now under scrutiny. These compounds resist breaking down and can travel through groundwater well past a fence line, which is why nearby installations matter to a water conversation. If you or your family served, the installations listed above are offered as context for where groundwater attention has concentrated, never as a verdict on anyone's home or health.
Yes. EPA UCMR 5 monitoring (2021–2024) tested 48 public water systems in South Carolina; 24 had at least one PFAS detection. Detections vary by water system — check your specific serving utility.
South Carolina tends to follow the federal framework rather than enforce a separate state limit. For residents on public systems, the standard that applies is the April 2024 federal rule the South Carolina Department of Environmental Services (SCDES) administers: 4 parts per trillion for PFOA and PFOS, and 10 for PFHxS, PFNA, and GenX.
The South Carolina Department of Environmental Services, through its Bureau of Water, oversees public water systems and carries out the monitoring required under federal rules, reporting detections to the public. It largely administers the federal PFAS limits rather than setting a stricter state ceiling.
The South Carolina Department of Environmental Services (SCDES) is the state environmental agency that took on environmental duties after South Carolina reorganized its former combined health-and-environment department. It oversees water quality, including PFAS monitoring in public drinking-water systems.
Use VetMyAddress to see the PFAS detections reported for the public water system serving any South Carolina address, alongside nearby military bases and industrial PFAS sources. The data comes from EPA UCMR 5, EPA TRI, and the DoD PFAS installation report.
In April 2024 the EPA set the first enforceable federal limits for PFAS in drinking water: 4 parts per trillion for PFOA and PFOS, and 10 ppt each for PFHxS, PFNA, and HFPO-DA (GenX), plus a Hazard Index for certain mixtures. Public water systems must complete initial monitoring by 2027 and come into compliance after that.
No. The federal limits apply to public water systems. Private well owners are responsible for their own testing and treatment, which is especially worth doing near a known PFAS source like a military base or industrial site.
State numbers tell you the pattern. An address report tells you what's actually in the water at yourkitchen sink — the matched utility, the PFAS detections on file, and every military or industrial source nearby. Whether it's for your family, your neighbors, or peace of mind.
