Well water testing in Bamberg County, South Carolina

What to test for in Bamberg County

Private wells are not regulated like public water: EPA advises owners to test their well every year for total coliform bacteria, nitrates, total dissolved solids and pH. Your state's own schedule:

• Clemson Extension says comprehensive testing should be done after a well is installed and whenever recent results are not available. That covers arsenic, chloride, copper, fluoride, hardness, iron, lead, manganese, nitrate, pH, radium, sodium, sulfate, total coliform bacteria, total dissolved solids (TDS) and uranium. It recommends annual testing for priority parameters, including bacteria, nitrates, TDS and pH, and a monthly visual check for changes in turbidity, color, odor or taste. source
• Clemson Extension suggests a minerals and metals analysis if you notice unusual taste, odor, or staining of laundry or plumbing fixtures, or if you are thinking about installing a water treatment system. source

Arsenic. USGS estimates that about 153 people using private wells in Bamberg County had arsenic above 10 µg/L, EPA's limit for public water (2010 base year; 95% range 108 to 218). USGS describes this kind of estimate as useful "for broad screening of the population at risk", so it says nothing certain about any one well. Arsenic has no taste or smell: test for it by name.

Radon. EPA puts Bamberg County in Zone 3: low potential (average indoor radon may be less than 2 pCi/L). That map is about radon in indoor air, and EPA says it should not be used to decide whether an individual home needs testing. If radon is found in your air and you have a well, EPA suggests testing the water too: see radon in well water.

For anything specific to your home (farms nearby, old plumbing, a new baby, a smell or stain), use the which-tests checklist. When the results arrive, check your numbers against EPA's limits.

PFAS in public water near Bamberg County (public supply, not your well)

Under EPA’s fifth Unregulated Contaminant Monitoring Rule (UCMR 5), public water systems sampled their water for 29 PFAS between Jan 3, 2023 and Jun 17, 2026. 2 public systems that serve ZIP codes mainly in Bamberg County reported results. 0 of them had at least one sample with PFOA or PFOS at or above 4.0 ng/L, and 0 had at least one of the 29 PFAS measured at or above its reporting level.

4.0 ng/L (parts per trillion) is both EPA’s UCMR 5 reporting level for PFOA and PFOS and the number in EPA’s 2024 limit for public water. That limit is judged on a running annual average, so one sample at that level is not a violation. EPA proposed changes to its PFAS rules in May 2026: see PFAS in well water for the current status and who should test a well. To test your own well, find a lab certified for PFAS.

Method: a system counts for this county when it reports serving a ZIP code whose largest land part is in this county, so a system serving several counties counts in each. Source: U.S. EPA, UCMR 5 occurrence data (by state), file dated Oct 15, 2026; downloaded Nov 1, 2026.

Testing programs and help in South Carolina

• SCDES says well owners over age 65, or on public assistance (such as food stamps, WIC or Medicaid), can get one coliform bacteria test and one metals and minerals analysis from its lab each year, free of charge. You need to provide a copy of a driver's license or proof of assistance. source
• SCDES has an application for private well owners who want their well assessed for PFAS. SCDES staff or contractors sample, test and give remediation recommendations. Where PFAS are found, owners may be eligible for a filtration system or for funding to connect to public water. source
• Clemson Extension's Be Well Informed program has a free, self-paced online course for well owners with modules on South Carolina water resources, well maintenance and water quality, plus a three-part fact sheet series on well components, water quality and treatment options. source
• For help understanding your results, SCDES points well owners to the Be Well Informed webpage, which gives feedback on health concerns and treatment choices. source
