Protecting Children from Lead in Boise

0.0043
mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

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 Boise do not determine the lead level at an individual tap. Testing is the only way to confirm your water's lead content.

Historical Flood-Claim Evidence for Boise

73
Total FEMA Flood Claims
$6,080
Avg Reported Sum With Payment Data
50%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Boise contains 73 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $6,080. Among ZIP codes with claim records, 50% 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 $750 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.

Source: historical FEMA National Flood Insurance Program (NFIP) claim records. No current FEMA property-map designation is asserted.
