Lead Service Line Compliance in South Carolina Water Systems

South Carolina has 1,163 public water systems serving approximately 4.7 million people. Under the EPA's Lead and Copper Rule Revisions (LCRR), all utilities were required to submit lead service line (LSL) inventories by October 2024—either documenting the pipes they know about or marking unknowns so the work of identification can continue.

Current Reporting Status

As of the October 2024 deadline, South Carolina's utilities submitted their inventories to the state primacy agency (South Carolina Department of Health and Environmental Control, or DHEC). The state's collective data shows 0 known lead service lines and 0 categorized as unknown across all reporting systems.

This snapshot reflects what utilities documented at submission time. It's important to understand what these numbers mean: they represent either confirmed LSLs or pipes where the material remains to be determined. Many utilities, particularly smaller ones, are still in the process of field investigations and records review to definitively classify their service lines.

What Happens Next

The LCRR requires utilities to continue working toward full inventory completion. Even if a utility reported zero unknowns in October 2024, ongoing work—including service line replacements, customer outreach, and records searches—may reveal additional pipes that need reclassification.

South Carolina's DHEC oversees compliance and can issue enforcement actions if utilities fall short of their obligations. Check DHEC's website or contact your local water utility directly for:

• Their specific LSL inventory results
• Their timeline for completing remaining identifications
• Whether your neighborhood is scheduled for field investigation or replacement work

Lead in Your Home

If you're concerned about lead in your drinking water, the EPA and CDC recommend:

• Have your water tested — contact your utility for a free or low-cost test kit
• Use cold water for drinking and cooking — hot water is more likely to corrode pipes and leach lead
• Flush your tap — let water run 30 seconds to 2 minutes before using it for drinking or cooking, especially first thing in the morning

For questions about health effects, consult your pediatrician or the CDC's lead poisoning prevention page.

Next Steps for Residents

• Contact your water utility and ask for their October 2024 LCRR inventory report
• Request information about LSL testing or replacement programs in your area
• Have your water tested if you haven't already
• Ask whether your home was built before 1986 (when lead solder use was still common)

However, utilities are still investigating—contact your local water utility to ask about their specific findings and whether your area has an ongoing testing or replacement program." }, { "q": "What should I do if I think my house has a lead service line?", "a": "Call your water utility and ask them to check their records and, if needed, conduct a field inspection. You can also have your water tested through your utility or a certified lab. If your home was built before 1986, ask about lead solder in indoor plumbing as well." }, { "q": "Is the water safe to drink right now?", "a": "Your utility is required to treat water to minimize lead corrosion and to test for lead regularly. If lead is detected above safe levels, your utility must notify you. Contact your utility directly to ask about their most recent water quality test results." }, { "q": "Where can I get my water tested for lead?", "a": "Contact your water utility first—many offer free or discounted testing. You can also use a certified laboratory; ask your utility for a list of certified labs in your area or check DHEC's website for approved testing facilities." }
