This report lists addresses of sanitary landfills and chemical and hazardous waste disposal sites and holding ponds with some form of impermeable lining. Liners included are polyethylene, polyvinyl chloride, Hypalon R, ethylene propylene diene monomer, butyl rubber, conventional paving asphalt, hot sprayed asphalt, asphalt-sealed fabrics, and concrete. Sites lined with treated soils including compacted clay, are also included in the list. Most of the sanitary landfills identified with impermeable liners are of recent construction, a few are 5 years old or more. A brief examination is also made of three possible methods for excavating a solid waste landfill to remove a small piece of liner for laboratory study. These methods are the use of the dragline, the backhoe, or the caisson. The methods are briefly described and compared as to suitability, and a preliminary cost comparison is given.
