Deterioration may occur due to aging or lack of imperviousness to certain chemicals or a combination of both. A Texas scientist studied newly developed landfill liners. In his study, eleven out of 12 liners leaked after just six months. In a test of four New Jersey landfills, each equipped with two separate liners, leakage began within a year. Wetlands are land areas that are naturally covered by shallow water at certain times and more or less drained at others.
Wetlands play an important part in the purifying and recharging of ground water.
Floridians located most of their landfills in wetlands and rely on groundwater for 92 percent of their fresh water. As a consequence Florida has more than 200 municipal landfill sites either on or waiting to be added to the Superfund list. It will cost between 10 and 100 million dollars to clean up each site. So much for cheap waste disposal. We do not need your scorn.
