mg/L Avg Lead (Limit: 0.015)

Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

Older stock in Dayton represents 78% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.

Dayton: NFIP Claim Records and Water-Quality Context

Avg Reported Sum With Payment Data

A/V Share of Claim-Record ZIPs

Historical NFIP data for Dayton contains 1 flood insurance claim. Among claims with payment data, the average reported building, contents, and ICC component sum is $755. 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 <strong>$2,400</strong> 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.
