Housing Age Profile
Development in Wann unfolded across multiple decades, and the median build year of 1999 reflects a housing inventory where eras of construction are genuinely mixed - including portions that predate the federal prohibition on lead solder in plumbing.
Most homes in Wann were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Wann: 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.
Although utility-side compliance with federal Lead and Copper requirements remains the system reference, that compliance does not extend down into interior plumbing. With 47% of Wann stock built before the solder ban and aggregate readings at or beyond the action mark, a household-level sample becomes the practical way to close that information gap.
