A Risk Mitigation Methodology for Solid Waste Landfills.
Abstract
Several recent models have attempted to simulate or assess the probability and consequences of the leakage of aqueous contaminant leakage from solid waste landfills. These models incorporate common factors, including climatological and geological characteristics. Each model, however, employs a unique approach to the problem, assigns different relative weights to factors, and relies upon extrapolated small-scale experimental data and/or subjective judgment in predicting the full-scale landfill failure mechanisms leading to contaminant migration. As a result, no two models are likely to equally assess a given landfill, and no one model has been validated as a predictor of long-term performance. The United States Air Force maintains a database for characterization of potential hazardous waste sites. Kecords include more than 500 landfills, providing such information as waste, soil, aquifer, and monitoring location data, and the results of sample testing. Through analysis of this information, nearly 300 landfills were assessed to have sufficiently, partially, or inadequately contained hazardous constituents of the wastes placed within them.
