Data similar to column test.

a Leachant composition depends on disposal location: pH 4.2 or pH 5 for east and west of Mississippi River, respectively.
b To be superceded by EN 12457-3.
c Suite of four tests - number of extractions depends on the characteristics (solids content) of the waste material.
