Housing & Infrastructure in Blue Island
With 77% 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
What does a median build year of 1968 mean for water safety in Blue Island? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Blue Island 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 Blue Island Homeowners
Although the Blue Island remediation share is moderate, it remains reachable for most homeowners who plan for the expense in advance.
Remediation costs are moderate relative to home values in Blue Island. The estimated $2,000–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 10% below the Illinois average.
Lead Exposure Risk for Children in Blue Island
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 77% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Blue Island.

Flood & Climate Risk in Blue Island
FEMA data shows 100% of Blue Island's ZIP codes mapped into designated flood zones, paired with an NFIP record of 4 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Blue Island has a moderate flood history with 4 FEMA claims averaging $65 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>$3,000</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.
