Bristow Infrastructure Age
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
Whether your home in Bristow was built before or after 1986 matters more than the citywide median of 2006, because the 1986 federal lead restrictions cover plumbing installed after that point.
Most homes in Bristow were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

How Remediation Costs Compare in Bristow
Because the median home value in Bristow is large relative to the estimated cost of remediation, the ratio between them stays at or below 1%; that is a statement about two area-level numbers, not a quote for a particular house or a judgment about what an owner can pay.
Estimated remediation costs in Bristow 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 87% above the Virginia average.
Bristow: Lead Risk & Vulnerable Populations
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.
4% of the Bristow housing stock dates from before 1986, the year Congress limited lead in pipes, solder and flux. Water systems report lead as the 90th percentile of their tap samples, and the average of those results across the city's ZIP codes is below 0.010 mg/L. Because lead in drinking water usually comes from corrosion of a building's own service line and plumbing, that average cannot stand in for a single address.

Bristow: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Bristow contains 9 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $1,737. 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.
