This webinar will discuss a case study involving damage to a 40 mil linear low density polyethylene (LLDPE) geomembrane (GM) installed in a below ground impoundment at a natural gas well site. Numerous defects were found in the LLDPE GM, including holes, scratches, indentations, and linear tears or slits, after the impoundment was drained (see photo above). The GM defects allowed leakage from the impoundment, which eventually was detected in nearby groundwater monitoring wells. An investigation of the GM, subgrade conditions, and pond operations was conducted to determine the cause and timing of the GM defects. This webinar will present the results of the investigation and the most likely cause(s) of the GM damage. 1.0 PDH
Cost: $500 per person
The $500 registration fee includes the four online course sessions and one sitting for the online certification exam. A University of Illinois - FGI CQA Certificate will be issued to those who successfully pass the online certification exam. For those who do not pass the exam on the first attempt, there is a $100 fee each time you register to re-take the online exam. Links to Parts 2, 3, and 4 will be sent automatically after registration for Part 1 is completed.
The FGI, in conjunction with The Ohio State University, Owens Corning Science and Technology, Ohio Environmental Protection Agency, Ohio Department of Natural Resources, and the Ohio Department of Transportation, is offering a Short Course on Geosynthetics in Civil Engineering Applications: water resources, containment, dams and conveyance, roadways, landfills, coal combustion residuals, MSE walls, and more.
