Pre-1970 (Lead Pipes Risk)
Pre-1970 (32%) 1970–1986 (11%) Post-1986 (57%)

A significant portion of Foster's housing stock predates 1970, so some homes may have older plumbing materials. Residents in older homes should consider water testing.

Protecting Children from Lead in Foster

43%
Homes Built Before 1986

Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
