Key Contaminants Detected in Centreville
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Centreville'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
Over the decades, Centreville accumulated housing from multiple construction periods. The median build year of 1999 can be read against 1986, when lead solder in plumbing became federally prohibited - a regulatory line, not a safety line, and individual homes on either side of it can have different plumbing.
Most homes in Centreville were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Centreville: Remediation Cost in Perspective
How large is the remediation estimate next to home prices in Centreville? Small in relative terms: it amounts to 1% of the median value or less, although the dollar figure below is still an estimate and actual costs vary by property and contractor.
Estimated remediation costs in Centreville can be compared with local home values. The $300–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 98% above the Virginia average.
Protecting Children from Lead in Centreville
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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical Flood-Claim Evidence for Centreville
Historical NFIP data for Centreville contains 30 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,807. 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 $500 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.

What You Can Do in Centreville
- 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. For Lead and Copper Rule, listed in the water-quality records for Centreville: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. With 34% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
