YANKTON Water System Lead Service Lines
Yankton serves about 15,400 people in South Dakota. Like all US water systems, Yankton is required to maintain an inventory of lead service lines—the pipes that connect the public water main to individual homes.
What we know about Yankton's lead pipes
Yankton has not yet completed or published a lead service line inventory. This does not mean there are no lead pipes in the system; it means the utility is still in the process of identifying them.
Lead service lines are a real concern because lead can leach into drinking water, especially from older pipes or in homes with corrosive water conditions. However, the presence of a lead service line does not automatically mean your water is unsafe—water quality depends on the pipe material, water chemistry, and other factors.
How inventories work
Water utilities are required by federal law to map out which homes have lead service lines, galvanized pipes (which can contain lead), and non-lead pipes. This process takes time, especially for larger systems. Utilities use records, field inspections, and sometimes water testing to build accurate inventories.
Once Yankton completes its inventory, the utility must make that information publicly available. You'll be able to find out whether your home is served by a lead service line.
Your options right now
Even without a completed inventory, you have steps you can take:
- Contact Yankton directly to ask about your specific address. The utility may have partial records or historical information about your home's service line.
- Get your water tested through a certified lab (not the utility's free test, which has limits). A lead test costs $20–30 and tells you whether lead is actually present in your tap water.
- Use temporary measures if you're concerned: let cold water run for 30 seconds before drinking or cooking, use a filter certified to remove lead (NSF Standard 53), and avoid hot tap water for drinking.
If you have young children or are pregnant, talk to your pediatrician or OB/GYN about lead exposure; the CDC has guidance for families too.

Frequently asked
Does Yankton have lead service lines?
Yankton has not yet published a complete inventory, so the exact number of lead service lines is unknown. The best way to find out if your home has one is to contact the utility directly with your address, or have your tap water tested by a certified lab.
Is it safe to drink tap water in Yankton?
Yankton treats and tests its water supply regularly. However, lead can come from pipes inside or leading to your home, not just the main system. If you're worried, get a lead test done; it's affordable and definitive.
How do I know if my house has a lead service line?
Call Yankton Water Utilities with your address. They may have records of your service line material. If they're unsure, a water test will tell you if lead is actually in your tap water.
Can lead service lines be replaced?
Yes. Replacement can be expensive, but some federal and state funding is available. Talk to your utility about options and whether your home qualifies for assistance programs.
