Thornton: Lead Risk & Vulnerable Populations

52%
Homes Built Before 1986

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 Thornton - 52% 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.
