The Environmental Protection Agency (EPA) initiated a multiphase study to determine a suitable replacement solvent for Freon-113, a class I CFC used in several EPA wastewater and solid waste methods for the determination of oil and grease and petroleum hydrocarbons. Conclusions from the Phase I study were used to narrow the list of alternative solvents to be considered in Phase II to n-hexane and cyclohexane. These solvents were evaluated for separatory funnel extraction and gravimetric determination of both oil and grease and total petroleum hydrocarbons (TPH) in aqueous samples. Triplicate analyses were performed for each of the solvents tested (i.e Freon-113, n-hexane, and cyclohexane) on each of 34 samples from a combination of inprocess and effluent waste streams collected from 25 facilities encompassing 16 different industrial categories. The objectives of Phase II were to find the alternative solvent that produced results closest to the results produced by Freon-113 and to develop an analytical method that incorporated this extraction solvent. In addition to studies of alternative solvents, solid phase disk extraction, solid phase cartridge extraction (also known as solid phase column extraction), non-dispersive infra-red spectroscopy, and immunoassay were voluntarily evaluated by vendors of the products using splits of each sample collected as part of the Phase II study.
