Key Contaminants Detected in Matteson
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Matteson's Housing Stock?
With 45% 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
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1980 places Matteson in the middle zone between those thresholds — with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
Most homes in Matteson were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Matteson: Remediation Cost in Perspective
In Matteson, documented water and safety issues can be addressed without making a meaningful dent in home equity — the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Matteson are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 24% above the Illinois average.
Protecting Children from Lead in Matteson
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 45% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Matteson.

Climate-Related Water Risk for Matteson
FEMA data shows 100% of Matteson's ZIP codes mapped into designated flood zones, paired with an NFIP record of 41 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Matteson has a moderate flood history with 41 FEMA claims averaging $3,504 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>$1,600</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.
