Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Lawrenceville
With 80% 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
While newer cities carry lower aggregate plumbing risk from lead-era construction, Lawrenceville sits firmly in the older category. The median build year of 1952 indicates that more than half the housing stock was built before 1986, when lead solder was still legally used in residential copper plumbing — and a substantial portion likely predates 1970, when lead pipes were still commonly installed for service lines. These two thresholds together define the elevated plumbing risk environment that older housing cities carry, independent of what the municipal water supply delivers to the meter.
Over half of homes in Lawrenceville 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 Lawrenceville Homeowners
Elevated equity share — Lawrenceville sits in the high tier when estimated remediation is measured against property values.
At 6.8% of home value, remediation costs in Lawrenceville represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $4,150–$9,600. Home values here are 47% below the Illinois average.
Lead Exposure Risk for Children in Lawrenceville
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.
Locally for Lawrenceville, the pre-rule housing share runs at 80%, and citywide utility monitoring has moved past the federal action mark. The high pre-1986 share combined with system samples crossing threshold places lead among the higher-priority household water concerns. Families with kids or pregnant residents can find a draw-test kit and certified filter via retailer-verified channels, with periodic retesting capturing changes after plumbing work or extended stagnation.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

Flood & Climate Risk in Lawrenceville
Lawrenceville's flood exposure sits in the moderate range: 15 NFIP claims on record and 100% of ZIP codes within FEMA-designated flood zones. Residents with private wells or older infrastructure have reasonable grounds to factor flood timing into their water quality awareness.
Lawrenceville has a moderate flood history with 15 FEMA claims averaging $9,247 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>$6,700</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.
