Key Contaminants Detected in Canyon Lake
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Canyon Lake'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
Plumbing materials follow installation dates, not medians. Canyon Lake records a median build year of 1994, and a meaningful share of its homes date from before the 1986 federal lead restrictions.
Most homes in Canyon Lake were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Canyon Lake: Remediation Cost in Perspective
Here the gap between local home values and the estimated repair bill is wide, so the percentage shown below for Canyon Lake stays at or under the 1% mark.
Estimated remediation costs in Canyon Lake can be compared with local home values. The $700–$2,300 estimated range can be set against the median property value; actual costs vary by home. Home values are 31% above the Texas average.
Protecting Children from Lead in Canyon Lake
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 Canyon Lake
Historical NFIP data for Canyon Lake contains 108 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $51,436. 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 $1,200 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.
