Description:
Hazardous wastes disposed of in landfills may continue to drain for several years after site closure. The report presents suitable analytical methods for predicting the flow of leachate to underdrains from closed hazardous waste landfills. Leachate sources include waste fluids as well as precipitation trapped in the landfill during construction and operation. Waste fluid may be released by means of barrel degradation, and interstitial fluid may be released during subsidence and/or compression of waste materials. Rates and amounts of leachate production can be estimated if the hydraulic parameters and/or specific yield information are available. Four simple landfill situations were analyzed with the unit-gradient and specific-yield models.
