leaching test

Refers to laboratory procedures that use water, acids, bases, organic solvents, salt solutions, or other liquids to estimate the types and concentrations of contaminants that will dissolve out of a solid waste or another solid sample.

of a solid material could potentially release problematic levels of contaminants into groundwater, surface waters, or other natural environments.
