Key Contaminants Detected in Gretna
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Gretna's Housing Stock?
With 76% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Pre-1986 homes make up a large part of Gretna's housing; median build year 1970.
Over half of homes in Gretna were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.
Source: U.S. Census Bureau ACS B25034.
Gretna: Remediation Cost in Perspective
The remediation-to-value ratio for Gretna sits at the bottom of the scale.
Estimated remediation costs in Gretna can be compared with local home values. The $525–$1,850 estimated range can be set against the median property value; actual costs vary by home. Home values are 32% above the Louisiana average.
Protecting Children from Lead in Gretna
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 Gretna
Historical NFIP data for Gretna contains 14,430 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $14,711. Among ZIP codes with claim records, 33% 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 $950 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.
