How Old Is Oak Hill's Housing Stock?
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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Oak Hill, the median build year of 1997 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
A significant portion of Oak Hill's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Protecting Children from Lead in Oak Hill
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 41% pre-rule share in Oak Hill keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
