Housing Age Profile
The median home in Sheldahl was built in 1978 - 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 Sheldahl were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Sheldahl Homeowners
Because property values in Sheldahl comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Sheldahl are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 6% above the Iowa average.
Lead Exposure Risk for Children in Sheldahl
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.
Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet - and where 70% of Sheldahl homes come from before the solder rule or where utility samples sit at or above the action mark, the gap between system data and faucet reality matters more than it does in lower-exposure communities. An in-home draw closes that gap, with certified filtration through retailer networks available where confirmed faucet results warrant additional measures.
