Housing Age Profile
The median home in Yankton was built in 1973 - a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.
Over half of homes in Yankton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Yankton: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 62% of Yankton stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.
