ASTM D7002 : 03

Standard Practice for Leak Location on Exposed Geomembranes Using the Water Puddle System

Standard Details

1.1 This standard is a performance-based practice for electrical methods for detecting leaks in exposed geomembranes. For clarity, this document uses the term "leak" to mean holes, punctures, tears, knife cuts, seam defects, cracks and similar breaches in an installed geomembrane (as defined in 3.1.5).

1.2 This standard can be used for geomembranes installed in basins, ponds, tanks, ore and waste pads, landfill cells, landfill caps, canals and other containment facilities. It is applicable for geomembranes made of materials such as polyethylene, polypropylene, polyvinyl chloride, chlorosulfonated polyethylene, bituminous geomembrane, and any other electrically-insulating materials.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
