Slideshow of Whales - Geomembranes
By Ian D. Peggs, Ph.D., P.E., P.Eng  – There continue to be failures of HDPE geomembrane lining systems in waste water treatment plant (WWTP) lagoons and farm manure ponds. These geomembrane whales, which are bubbles that develop under the geomembrane, are generally caused by leakage through the liner, the inability to remove leakage, the generation of methane, and the...
