TCLP results from the preliminary survey were used to select 4 products to test the repeatability of the leaching experiments and compare the results of two hazardous waste leaching tests. Two products leaching elevated (x > 1 mg/L) amounts of lead and two products leaching undetectable (x < 0.004 mg/L) amounts of lead were selected for replicate analysis by TCLP and WET. For all products leached by TCLP, extraction solution #1 was used in the experiment. Samples were rotated for 18 ± 2 h in high-density polyethylene extraction vessels (Fisher), then vacuum filtered with acid-washed glass fiber filters (Whatman). Control blanks were also digested. Final extract pH ranged from 4.79 to 6.16. Extracts were digested and acidified below pH 2.0 with nitric acid for sample preservation. Samples were stored at 4 C until analysis. Samples were analyzed by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES, iCAP 6000 Thermo Scientific).
