0.002

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.

Lead risk in Dover appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

50%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Dover contains 100 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $15,478.

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>$780</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.
