Housing & Infrastructure in Blandinsville
With 82% 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.

Housing Age Profile
Reading the housing age data for Blandinsville — median build year 1960 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Blandinsville 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 Blandinsville Homeowners
Property values and remediation costs in Blandinsville combine to produce a high equity share — the financial burden here is significant.
At 2.9% of home value, remediation costs in Blandinsville represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,600–$3,300. Home values here are 56% below the Illinois average.
Lead Exposure Risk for Children in Blandinsville
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 82% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Blandinsville.

Flood & Climate Risk in Blandinsville
Blandinsville's NFIP record shows a low claim total — a pattern that keeps the link between flooding and water quality in the background rather than the foreground. Treatment infrastructure can be overloaded by severe flood events, but that scenario requires event frequency and magnitude that the area's claim history suggests have not materialized here.
Blandinsville has a relatively low flood history with 6 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
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>$2,400</strong> remediation cost per household.
