ESTIMATING OIL AND GREASE CONTENT OF PETROLEUM-CONTAMINATED SOIL

The determination is reported of the suitability of methylene chloride as a substitute for freon in the gravimetric estimation of the oil and grease content of petroleum-contaminated soils by Soxhlet extraction. Precision and accuracy were the criteria used in the study to assess suitability. The results of the study show that acidification followed by Soxhlet extraction with freon or methylene chloride using the modification of APHA (Americal Public Health Administration) 503D and EPA (Environmental Protection Agency) 9071 developed by Martin and Loehr (1985) is precise, and results in reasosnable recoveries when used to measure the oil anmd grease content of petroleum-contaminated soils. There appears to be no need to continue using freon since methylene chloride will provide comparable results.
