Tiffin: Lead Risk & Vulnerable Populations

10%
Homes Built Before 1986

Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

Homes built before 1986 are more likely to have lead pipes, fixtures or solder, and census figures put that share of Tiffin housing at about 10%. The lead figure used here, an average of ZIP-level 90th-percentile results, sits under 0.010 mg/L. Neither number shows what flows from a particular family's faucet; a test of that faucet is the only direct measure.
