Key Contaminants Detected in Warrenton
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Warrenton's Housing Stock?
With 46% 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
Roughly balanced between older and newer construction, Warrenton shows a median build year of 1982 - a mid-range figure that places meaningful amounts of the residential inventory on both sides of the 1986 federal plumbing-solder ban.
Most homes in Warrenton were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Warrenton: Remediation Cost in Perspective
Because property values in Warrenton comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Warrenton are relatively low compared to home values. The $1,867–$3,833 estimated range is a small fraction of median property value. Home values are 92% above the Virginia average.
Protecting Children from Lead in Warrenton
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.
46% - that captures the slice of Warrenton housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.

Historical Flood-Claim Evidence for Warrenton

Among ZIP codes with claim records, 0% 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. The <strong>$2,800</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.
