This article presents rapid methods for the extraction and subsequent analysis of organics in soils potentially contaminated from chemical wastes. A methylene chloride extraction, on both a micro scale in a syringe and a macro scale in a shaken flask, with subsequent gravimetric analysis are described. On wet soils, anhydrous sodium sulfate is added to bind the water before adding methylene chloride and mixing with a vortex touch mixer. A baseline procedure is the direct gravimetric determination of volatile organics corrected with a Karl Fischer determination of water. Estimates of time saved by using the rapid methods, as well as precision and accuracy data, are presented.
