Homes Built Before 1986
0.011
mg/L Avg Lead (Limit: 0.015)

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 60% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Edgerton.
