Logan: Lead Risk & Vulnerable Populations
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 Logan do not determine the lead level at an individual tap. Testing is the only way to confirm your water's lead content.

Logan: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Logan contains 27 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $5,521. 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.
