Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is South Beloit's Housing Stock?
With 50% 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
Pre-1986 plumbing is not a rare legacy case in South Beloit — it's the dominant profile. The median build year of 1983 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in South Beloit were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

South Beloit: Remediation Cost in Perspective
The equity-to-remediation ratio in South Beloit is moderate — worth planning for but within reach for most property owners.
Remediation costs are moderate relative to home values in South Beloit. The estimated $2,050–$4,700 range is manageable for most homeowners but still worth budgeting for. Home values are 6% below the Illinois average.
Protecting Children from Lead in South Beloit
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 50% of South Beloit stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.

Climate-Related Water Risk for South Beloit
The NFIP claim record for South Beloit — 43 filed incidents — reflects genuine, recurring flood exposure rather than an isolated event or two. When a community accumulates flood claims at this volume and carries 100% of its ZIP codes inside FEMA-designated zones, flood history starts to factor into water quality planning in ways it doesn't for lower-exposure areas. Flooding introduces specific contamination pathways — runoff overwhelming treatment facility intake, surface water infiltrating private wells, and pressure disruptions in distribution systems allowing backflow — all of which become more relevant as flood frequency increases.
South Beloit has a moderate flood history with 43 FEMA claims averaging $3,350 per payout. 100% 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>$3,200</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.
