The City of Fort Worth, Water Department conducted an evaluation of the Atlantic™ solid phase extraction (SPE) C18 disks using EPA Method 608. This application note describes the procedure to determine low ppb levels of organochlorine pesticides and PCBs in wastewater. This procedure used methylene chloride as the primary extraction solvent, followed by a hexane solvent exchange. Extracts were then analyzed by GC/ECD using a pressure pulse injection technique.
