Regulations under the Resource Conservation and Recovery Act of 1976 (RCRA) include the option of evaluating solid wastes for toxicity by extracting the waste with an acid solution and analyzing the extract for certain toxic metals and pesticides. In this study the three acid extraction procedures compared were the Minnesota Pollution Control Agency (MPCA) “Land Disposal Leach Test,” the proposed American Society for Testing and Materials (ASTM) “Leaching of Waste Materials,” and the “Extraction Procedure” described in 40 CFR 250.13(d)(2) of the U.S. Environmental Protection Agency's (EPA) proposed regulations implementing Section 3001 of RCRA. Variables of interest in the three procedures included pH, liquid-to-solid ratio, particle size, duration of extraction, and mixing (shaking) method. Generally, greater amounts of metals were extracted (leached) at the lower pH levels regardless of the test procedure used. EPA and MPCA criteria were used to classify the wastes as hazardous or nonhazardous.
