Housing Age Profile
The story of Roundhill's housing stock is one of layered development — neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 1998 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards — creating a risk environment that the city-wide aggregate water data doesn't fully capture.
A significant portion of Roundhill's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Roundhill: Remediation Cost in Perspective
At current valuations, Roundhill sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Roundhill are relatively low compared to home values. The $300–$1,600 estimated range is a small fraction of median property value. Home values are 31% above the Kentucky average.
Protecting Children from Lead in Roundhill
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 45% pre-rule share in Roundhill keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
