Wilmington: Lead Risk & Vulnerable Populations
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.
Available area-level lead records for Wilmington do not determine the lead level at an individual tap. Testing is the only way to confirm your water's lead content.

Wilmington: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Wilmington contains 3,643 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $22,442. Among ZIP codes with claim records, 89% 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 $667 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.
