Highland Park: 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.
How much lead reaches a given Highland Park faucet depends on that building's service line and plumbing, and area data cannot settle it. What the data do show is an average of 90th-percentile lead results above 0.015 mg/L across the city's ZIP codes and a housing stock that is 75% pre-1986. The utility's lead service line inventory and a certified laboratory tap test are direct checks for a household.
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.

Highland Park: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Highland Park contains 141 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $6,642. 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 $4,500 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.
