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.

Water systems' 90th-percentile values for lead, averaged over Milton ZIP codes, reach 10 micrograms per liter or above; 26% of homes are older than 1986.

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.

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 $500 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.
