Lead Exposure Risk for Children in Hallett
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 67% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Hallett.
