TCLP is designed to determine the mobility of both organic and inorganic analytes present in liquid, solid, and multiphasic wastes. This procedure describes the leaching technique which is then followed by analytical methods to determine metals, pesticides, herbicides, semi-volatiles, and volatiles. The regulatory limits for the TCLP compounds are listed in the "Typical Detection Limit" column below.

| Hold Times, Preservatives, Preps, Collection, Analytical & Documentation | |
|---|---|
| Holding Time: | From collection to TCLP: Volatiles & Semi-volatiles 14 days, Mercury 28 days, Metals 180 days; From TCLP to extraction: Semi-volatiles 7 days; From extraction to analysis: Volatiles 14 days, Semi-volatiles 40 days, Mercury 28 days, Metals 180 days |
| Preservatives: | None prior to extraction; may be refrigerated unless it results in irreversible change to the waste; volatile samples at 4 °C |
| Required Preps: | Samples to be analyzed for volatiles require teflon lined septum capped vials |
| Collection Method: | Grab sampling |
| Analytical Methodology: | Metals by ICP or GFAA by EPA 200 methods; GC/ECD by SW-846 8081A for pesticides; GC/ECD by SW-846 8151A for herbicides; GC/MS by SW-846 8270C for semivolatiles; GC/MS by SW-846 8260B for volatiles |

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
