The groundwater of Suffolk County, New York, is designated as a sole source aquifer and in recent years there have been increasing concerns about the contamination of this water by agricultural chemicals. Two parallel treatment systems were evaluated for a one-year period: granular activated carbon (GAC) plus ion exchange and reverse osmosis. GAC effectively removed the SOCs evaluated at Suffolk County, New York. Rejection of the more volatile compounds such as 1,2, dichloropropane by reverse osmosis appears more effective with thin-film composite rather than the hollow-fiber polyamide membrane.
