How Old Is Lillie's Housing Stock?
With 47% 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
Tap water lead levels are shaped by two factors: what the utility delivers, and what the household plumbing adds to it. Older homes contribute disproportionately to that second variable because lead solder was standard in copper plumbing before 1986, and lead pipes were common before 1970. In Lillie, where the median build year is 1983, a substantial share of the housing stock falls into these older categories. The bar chart above breaks out the pre-1970, 1970-to-1986, and post-1986 segments — the key ages for understanding where plumbing-era risk concentrates across the city.
Most homes in Lillie were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Lillie
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.
Practically, the structural drivers in Lillie — 47% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark — make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.
