Lead Service Lines in South Dakota

South Dakota has 715 water systems serving roughly 917,000 people. Right now, the state has not reported any confirmed lead service lines in its inventory data.

What does this mean for you?

A lead service line is the pipe that connects your home to the public water main. If yours contains lead, water can pick up the metal as it travels to your tap. The EPA requires all water systems to test for lead and report what they find.

South Dakota's current inventory shows zero known lead lines across the state. However, this doesn't necessarily mean lead lines don't exist—it may mean they haven't been fully identified yet. Many water systems nationwide are still in the early stages of mapping their pipes.

How to find out about your water system

Your water utility is required by federal law to publish an annual water quality report (called a "Consumer Confidence Report"). This report includes information about lead testing and service line materials.

To check your system:

  • Search for your water provider on this directory to see what they've reported.
  • Contact your water utility directly and ask: "Do you have any lead service lines?" and "When is your inventory complete?"
  • Request a copy of their most recent Consumer Confidence Report.

The utilities listed above are among those serving South Dakota residents. If your area is served by one of these systems, you can reach out to them for specifics about your neighborhood or address.

What you can do right now

Even without confirmed lead lines in your area, reducing lead exposure is straightforward. Let cold water run from your tap for 30 seconds before drinking or cooking if your water has been sitting overnight. Use only cold water for cooking and drinking. If you're concerned about lead in your home's pipes or plumbing, a water test can tell you if it's present.

Next steps for residents

  • Contact your local water utility and ask about their lead service line inventory status.
  • Request a copy of their latest water quality report.
  • If you want your home's water tested for lead, ask your utility for a list of certified labs.
  • For health concerns, speak with your pediatrician or contact your local health department.
