Housing & Infrastructure in Lawrenceville
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Housing age is a rough starting point, not an answer. Lawrenceville has a median build year of 1995, but any single home may be older or newer than that figure, may have had plumbing replaced, or may still have original fixtures. Lead can also come from a service line or older brass fittings, so a water test or a check of the utility's service line inventory says more about one address than the citywide build year does.
Most homes in Lawrenceville were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Lawrenceville
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Averaged across Lawrenceville ZIP codes, the 90th-percentile lead results reported by water systems come to less than 10 parts per billion. That is an area summary rather than a reading from any home, and EPA's health goal for lead in drinking water is zero; about 26% of local housing predates 1986.

Historical NFIP Claim Context in Lawrenceville
Historical NFIP data for Lawrenceville contains 163 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $32,595. Among ZIP codes with claim records, 25% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.

What You Can Do in Lawrenceville
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. Choose a pitcher or under-sink filter certified to reduce the specific contaminants of concern.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
