Bench-scale treatment data for membrane and granular activated carbon technologies are presented for the organic contaminants on the U.S. Environmental Protection Agency's Contaminant Candidate List (CCL). For granular activated carbon (GAC), isotherm results are presented and quantitative structure property relationships are used in conjunction with existing column models to calculate carbon use rates that account for the deleterious effects of natural organic matter fouling. For membrane processes, the screening-level experiments were conducted with a spiral-wound membrane that treated a spiked groundwater. The mean bulk rejections for the CCL contaminants are presented for multiple pressures and recoveries. Judging from the results, both GAC and membrane technologies are expected to be highly successful in removing many of the organic contaminants on the CCL. Additional studies will be needed to develop full-scale cost information. Includes 20 references, tables, figure.
