Project GOOD (Bare-Puddle)
A bare-geomembrane water puddle survey was performed according to ASTM D7002-16 on the secondary geomembrane in a double-lined system. Prior to installing the primary geomembrane, Client required an electrical leak location survey be performed to verify the integrity of the secondary containment system. The geoelectric survey area was approximately 4.8 acres and consisted of a newly installed 60-mil Microdrain geomembrane.
Leaks found using the bare-geomembrane water puddle survey method
Three penetrations were found, repaired, and rechecked.
