In this study, a series of extraction recovery experiments were performed using the Corning design to determine the: Effect of the various extraction variables (temperature, etc.) and the necessity for design modifications and/or changes to extraction protocols required to improve target compound recoveries and ruggedness of the procedure; Recovery of semivolatile organics, pesticides and PCBs listed as target compounds under the Superfund Contract Laboratory Program, EPA methods 608 (Pesticides and PCBS) and 625 (NPDES) and 508 (SDWA); Ease and practicality of use; Consistency with the Agency's mandatory analytical procedures. Effectiveness of the extractor in recovering solvent and in performing the K-D concentration; and Comparison with the performance of the 'mini' continuous extractor.
