Top Contaminants in Belleville Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Belleville
With 68% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Because the majority of Belleville's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1970 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Belleville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Belleville Homeowners
The equity impact of remediation in Belleville sits at a moderate level — real enough to plan for, within reach for most.
Remediation costs are moderate relative to home values in Belleville. The estimated $1,090–$3,640 range is manageable for most homeowners but still worth budgeting for. Home values are 12% below the Illinois average.
Lead Exposure Risk for Children in Belleville
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Older stock in Belleville represents 68% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Flood & Climate Risk in Belleville
Over the multi-decade window covered by the National Flood Insurance Program, Belleville has accumulated 150 claims — a total that suggests more than isolated flood exposure. With 80% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
Belleville has a moderate flood history with 150 FEMA claims averaging $8,646 per payout. 80% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$2,160</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
