LeachXS is a database/expert decision support system for characterization and environmental impact assessment based on estimated contaminant release as derived from leaching tests. Applicable materials for assessment include: Soils and Contaminated Soil, Sludge, Compost, Sediments, Municipal Wastes, Industrial and Hazardous Wastes, Mining Wastes, Preserved Wood, Treated Wastes, Stabilized Waste, Construction Materials, Cement Mortars and Concrete.
The materials leaching database contains results of laboratory leaching tests, various lysimeter test results and field data from more than 600 materials and wastes. In a few cases, interrelated laboratory, lysimeter and field scale data are available.
Leaching tests are interpreted in an expert system to provide estimates of the short and long term release of constituents of interest. This makes the database/expert system a unique tool to study the release behavior of different materials when used, recycled or landfilled.
