Key Contaminants Detected in Mission
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Mission'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
Federal restrictions on lead pipe, solder and flux in new drinking water plumbing date from the 1986 Safe Drinking Water Act amendments; the median build year of 1997 for Mission is one reference point against that date.
Most homes in Mission were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Mission: Remediation Cost in Perspective
This section sets two area figures side by side for Mission: the median home value and an estimated remediation cost. Here the estimate equals no more than 1% of that value, which places the city in the low tier; it is an area estimate, and the cost for any one property can be higher or lower.
Estimated remediation costs in Mission can be compared with local home values. The $550–$2,000 estimated range can be set against the median property value; actual costs vary by home. Home values are 47% below the Texas average.
Protecting Children from Lead in Mission
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.
Homes built before 1986 are more likely to have lead pipes, fixtures or solder, and census figures put that share of Mission housing at about 21%. The lead figure used here, an average of ZIP-level 90th-percentile results, sits under 0.010 mg/L. Neither number shows what flows from a particular family's faucet; a test of that faucet is the only direct measure.

Historical Flood-Claim Evidence for Mission
Historical NFIP data for Mission contains 628 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $28,837. 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 $1,000 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.
Source: historical FEMA National Flood Insurance Program (NFIP) claim records. No current FEMA property-map designation is asserted.
What You Can Do in Mission
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Public Notice Rule, listed in the water-quality records for Mission: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
