Cub Run Infrastructure Age
With 41% 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
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Cub Run, the median build year of 1997 indicates that plumbing age is a material factor in local lead risk — with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in Cub Run were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Cub Run
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Cub Run is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Cub Run are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 4% above the Kentucky average.
Cub Run: 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.
Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet — and where 41% of Cub Run 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.
