| Leak Detection for Landfill Liners: Overview of Tools for Vadose Zone Monitoring. This report was prepared under grant for EPA by Karen Hix, a National Network of Environmental Management Studies (NNEMS) fellow. It is intended to provide a basic summary and current status on several innovative types of leak detection tools that can be installed, in addition to monitoring wells, for identifying leaks in landfill liners. The document is not intended to be an inclusive report; it merely provides an overview of the existing work on leak detection technologies. The information was gathered by the author from a range of available sources, including project documents, reports, periodicals, Internet searches, and personal communication with involved parties. |
