Specifying Allowable Geomembrane Leakage Rates Based on Available Technology
Engineering and regulatory specifications for allowable leakage through geomembranes should be consistent with state-of-the-art technologies for locating leaks. In many actual cases, surface impoundments are allowed to leak an order of magnitude more than what could be easily attained by locating leaks using currently available leak detection technologies. In some cases for landfills, if an allowable leakage rate is exceeded, there is no technology that can be used to locate the small leak or leaks for repair. ASTM D7007, the established standard for geomembrane leak location with water or earth materials on the geomembrane, and a mathematical equation for leakage rate versus size of the leak are used to examine what is achievable and what is unrealistic for the specification of allowable leakage rates. Specification writers and design engineers should specify low, but realistic allowable leakage rates that can be attained using geomembrane leak location surveys.
