Key Contaminants Detected in Lewisville
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Lewisville'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
Prohibited from residential plumbing since 1986, lead solder divides Lewisville's housing stock along a timeline that the median build year of 1996 straddles. A meaningful share of homes predates the ban - a configuration that places moderate aggregate pressure on plumbing-related lead risk, distributed unevenly across neighborhoods.
Most homes in Lewisville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lewisville: Remediation Cost in Perspective

Remediation costs in Lewisville are relatively low compared to home values. The $1,075–$2,725 estimated range is a small fraction of median property value. Home values are 41% above the Texas average.
Protecting Children from Lead in Lewisville
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.
34% of Lewisville housing dates to the pre-rule era, alongside aggregate readings hovering at the federal action mark - household-level confirmation through a draw-test kit fits the local picture.

Historical Flood-Claim Evidence for Lewisville
Historical NFIP data for Lewisville contains 117 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $26,516. Among ZIP codes with claim records, 67% 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>$1,725</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.
