Lead Exposure Risk for Children in Chinook

51%
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.

Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 51% of Chinook stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.
