Housing Age Profile

Over the decades, Foster accumulated housing from multiple construction periods. The median build year of 1993 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited - leaving a sizable share of homes on each side of that safety line.

Protecting Children from Lead in Foster

43%
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 43% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Foster.
