Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Travis Afb's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
When a home in Travis Afb was built matters for lead because federal rules adopted in 1986 limited how much lead new plumbing could contain; the local median build year is 1995. A median sits in the middle of a range, so some homes are older and some newer, and past repairs may have changed the pipes in either group. A plumber can identify the materials inside a home, and a lab test measures what reaches the tap.
Most homes in Travis Afb were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Protecting Children from Lead in Travis Afb
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.
No safe blood lead level in children has been identified, according to CDC, so an area average under 0.010 mg/L does not rule out exposure at home. In Travis Afb, 30% of homes were built before 1986.

Historical Flood-Claim Evidence for Travis Afb
Historical NFIP data for Travis Afb contains 1 flood insurance claim.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The $300 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
