Description:
An electrical resistivity survey technique has been developed and tested for assessing the integrity of geomembrane liner systems installed in fluid impoundments. Development of the technique has included two-dimensional computer modeling and three-dimensional physical model testing. A one-acre geomembrane lined surface impoundment was used for full-scale testing of the technique. Tests were conducted to detect and locate single and multiple leaks of different sizes. Results indicate the technique can be used to detect and locate single and multiple leaks as small as one inch in diameter with an accuracy of five feet or less.
