Key Contaminants Detected in Kemah
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Kemah'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
Since 1986, federal law has prohibited lead solder in new residential plumbing. With a median build year of 1994, much of Kemah's housing falls on the safer side of that line - though homes built before 1986 still warrant testing regardless of the city-wide profile.
Most homes in Kemah were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Kemah: Remediation Cost in Perspective
Property equity in Kemah runs well ahead of estimated remediation costs - a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.
Remediation costs in Kemah are relatively low compared to home values. The $1,500–$3,300 estimated range is a small fraction of median property value. Home values are 65% above the Texas average.
Protecting Children from Lead in Kemah
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.
Through the multi-year window of EPA Lead and Copper Rule monitoring, Kemah has stayed under the action mark. Paired with a 29% pre-rule housing share, the result places lead in a lower-priority spot on the local picture - without erasing the structural gap between citywide averages and what arrives at one specific tap.

Historical Flood-Claim Evidence for Kemah
Historical NFIP data for Kemah contains 3,106 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $33,152. 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>$2,300</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.
