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.

Port Aransas: NFIP Claim Records and Water-Quality Context

100%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Port Aransas contains 3,486 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $61,681.

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 $1,100 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.
