Most homes in Valley Park were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Valley Park
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.

Historical NFIP Claim Context in Valley Park
Historical NFIP data for Valley Park contains 2,250 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $17,332. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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 $800 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.
