Protecting Children from Lead in Rehoboth Bch
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.
Two pieces of area data frame lead for Rehoboth Bch families. First, the average of ZIP-level 90th-percentile lead results is 0.010 mg/L or higher. Second, census figures put homes built before 1986, which are more likely to contain lead pipes, fixtures or solder, at about 38% of the housing stock. Neither figure measures a particular home, so a certified lab test of the tap water is the step that shows the lead level there.
1 ZIP code (100% of the city's ZIP records) is served by a water system whose 90th-percentile lead result exceeds the EPA action level of 0.015 mg/L.

Historical Flood-Claim Evidence for Rehoboth Bch
Historical NFIP data for Rehoboth Bch contains 880 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,076. 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 $600 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.
