All liners perform worse than anyone suspected.
Geoservices didn't have much good to say about clay liners. However, based on actual experience in the field, Geoser vices concludes that this ideal permeability is often not achieved for a variety of reasons. It won't take very long to contaminate a large drinking water supply if you pour 90 to 900 gallons of toxics into it day after day, year after year. Thus Geoservices has shown that clay liners are an environmental disaster. However, it is important to realize that all materials used as liners are at least slightly permeable to liquids or gases and a certain amount of permeation through liners should be expected.
