Lead service lines in Columbia, SC

Columbia's water systems serve about 357,600 people across 162 different water utilities. The largest system, Columbia City of, serves roughly 319,500 residents.

What we know about lead service lines in Columbia

Currently, there are no confirmed lead service lines reported in Columbia's water systems inventory data. However, this doesn't mean lead pipes don't exist in the area — it means the utilities haven't yet completed their lead service line inventories or haven't reported the data publicly.

Federal law requires all water utilities to identify and catalog lead service lines by 2026. Many utilities are still in the early stages of this work. If your water system hasn't finished its inventory, they may discover lead lines when they inspect pipes in your neighborhood.

Galvanized pipes are another concern

Galvanized steel pipes (older pipes coated with zinc) can also leach lead, especially if the water is corrosive. No galvanized pipes have been reported in Columbia's current data, but again, this reflects reporting status, not necessarily the actual pipes underground.

Where lead lines are most common

Lead service lines are most likely in homes built before 1986. If your house was constructed before the mid-1980s, your service line is more likely to contain lead or galvanized steel. Even if you don't have a lead service line, lead can still enter your water from older fixtures inside your home (faucets, solder, or brass components).

What to do about your specific address

Your water utility can tell you whether your property has a lead service line. Contact Columbia City of or your local water system directly — they're required to provide this information. If you can't find your utility, check your water bill or call your city or county water department.

If you're concerned about lead in your drinking water, a simple water test can identify it. Some utilities offer free or low-cost testing; otherwise, certified labs in South Carolina can test for you.

Next steps for residents

  • Find your water utility. Check your water bill or call the City of Columbia's Public Services Department.
  • Ask about lead service lines. Request your service line status and any available water quality reports.
  • Test your water if you're concerned. A lead test costs $20–50 at most labs and gives you a clear answer.
  • For health questions, contact your pediatrician or the CDC. They can advise based on your household's specific situation.
