Key Contaminants Detected in Manchaca
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Manchaca'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
Over the decades, Manchaca accumulated housing from multiple construction periods. The median build year of 1994 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited - leaving a sizable share of homes on each side of that safety line.
Most homes in Manchaca were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Manchaca: Remediation Cost in Perspective
Low proportionality - that's the Manchaca picture when remediation costs are placed against typical home equity.
Remediation costs in Manchaca are relatively low compared to home values. The $2,350–$5,400 estimated range is a small fraction of median property value. Home values are 111% above the Texas average.
Protecting Children from Lead in Manchaca
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 37% of the Manchaca inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.

Historical Flood-Claim Evidence for Manchaca
Historical NFIP data for Manchaca contains 70 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $89,765. 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>$3,400</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.
