Key Contaminants Detected in Williamsburg
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Williamsburg's Housing Stock?
With 52% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Williamsburg's median build year of 1985 places it squarely in that category.
Over half of homes in Williamsburg were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Williamsburg: Remediation Cost in Perspective
Within the Williamsburg property market, documented remediation claims a moderate slice of typical equity - real but budgetable.
Remediation costs are moderate relative to home values in Williamsburg. The estimated $2,350–$6,200 range is manageable for most homeowners but still worth budgeting for. Home values are 7% above the Ohio average.
Protecting Children from Lead in Williamsburg
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 52% pre-rule share in Williamsburg keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Historical Flood-Claim Evidence for Williamsburg
Historical NFIP data for Williamsburg contains 7 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $99,641. Among ZIP codes with claim records, 100% 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>$3,800</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.
