Housing Age Profile

Lead can reach tap water from service lines, solder and brass fittings inside a building, which is why housing age draws attention in Belleville, where the median build year is 1970.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (50%) 1970–1986 (18%) Post-1986 (32%)

Over half of homes in Belleville were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lead Exposure Risk for Children in Belleville

68%

Homes Built Before 1986

0.003

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.

If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Total FEMA Flood Claims

Avg Reported Sum With Payment Data

50%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Belleville contains 150 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $11,799. 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 $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.
