One set of split samples was retained by DNREC's laboratory xand the other set of splits was shipped to Triangle Laboratory in Research Triangle Park, North Carolina. The DNREC labwas given instructions to analyze the split samples for Aroclors using conventional gas chromatography/electron capture detection.
