Piru: Lead Risk & Vulnerable Populations

48%
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.

Pulling a tap sample fills the gap that utility data cannot close, particularly here where 48% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Piru.
