in dilute acetic acid for 16 to 20 h, filtered, and the filtrate is analyzed for the required metals and
organic compounds. Where the waste contains less than 0.5% filterable solids, the waste itself is con-
sidered to be the extract. Details of the method are provided in TCLP, Method 1311 (U.S. EPA, 1986).
If the extract from a representative waste sample contains any of the contaminants listed in
Table 11.3 at a concentration greater than or equal to the regulatory level, the waste exhibits the
