Key Contaminants Detected in Stewartsville
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Stewartsville's Housing Stock?
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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Stewartsville, the median build year of 1996 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Stewartsville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Stewartsville: Remediation Cost in Perspective
Across Stewartsville, the equity share taken up by estimated remediation is small - a favorable ratio for most property owners.
Remediation costs in Stewartsville are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 12% below the New Jersey average.
Protecting Children from Lead in Stewartsville
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 33% of the Stewartsville inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

Historical Flood-Claim Evidence for Stewartsville

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. The <strong>$2,400</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
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.
