How Old Is Kirkman's Housing Stock?
With 97% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Kirkman - it's the dominant profile. The median build year of 1959 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Kirkman were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Kirkman: Remediation Cost in Perspective
In Kirkman, property wealth outpaces what documented remediation typically demands - the equity burden lands well within the low tier.
Remediation costs in Kirkman are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 48% above the Iowa average.
Protecting Children from Lead in Kirkman
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 97% of Kirkman 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.
