Housing & Infrastructure in Bolingbrook
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Homes on the same street in Bolingbrook can differ: one may keep original pre-1986 plumbing while another has been replumbed, so the 1990 median is only a starting point.
Most homes in Bolingbrook were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Bolingbrook
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.
Households with young children in Bolingbrook have two area numbers to weigh. One is the mean of 90th-percentile lead values reported for local ZIP codes, which is at or above 0.010 mg/L; the other is the 36% share of housing that dates from before 1986. Neither describes one home, and sending a tap sample to an accredited laboratory is how a family measures its own lead level.
1 ZIP code (50% 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.

Historical NFIP Claim Context in Bolingbrook
Historical NFIP data for Bolingbrook contains 101 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $22,442. 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 $4,640 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.
