Housing & Infrastructure in Walnut Hill
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Walnut Hill, the median build year of 1998 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Walnut Hill were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Walnut 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.
Older stock in Walnut Hill represents 40% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.
