Abstract:

Prediction of waste or fill leachate quality is often an important consideration, as it can be used in determining material placement, drainage designs, leachate containment (clay liner), or surrounding material interaction evaluations and identifying potential impacts to hydrologic regimes, ecological systems, or treatment requirements. In additon, leachate characteristics are often used to classify materials (e.g., hazardous wastes or acid-producing overburden or fill). There are several leachate evaluation test methods, which range from predicting the potential presence of selected characteristics within possible leachates to actual leachate quality determinations of representative materials by using representative leachate fluids. Because cost and time requirements vary with each leachate prediction test, the test method chosen to evaluate a material's potential leachate quality should be based on information requirements of the investigation. Several nonleaching, batch, and column leaching tests were examined as to information that can be obtained from these leachate prediction techniques. Several of these leachate quality prediction techniques, which included reaction pH, total sulfur, acid-base accounting, American Society of Testing and Materials 1:4 shake extraction of solid waste with water, U.S. Environmental Protection Agency extraction procedure toxicity test, and periodic column leaching tests, were than applied to several waste materials. The resulting test data were then compared. The application and usefulness of the various testing procedures in predicting leachate quality of inorganic parameters are discussed. (Author)
