Abstract: The present invention relates to a method for determining trace amounts of crude oil in water, including the steps of collecting a sample of an oil-containing fluid, adding a toluene extraction volume to the sample, perturbing the sample, dissolving substantially all of the amount of oil in the toluene extraction volume to create a mixed sample, extracting the mixed sample to create an oil-in-toluene layer and an aqueous fluid layer, removing a portion of the oil-in-toluene layer into a dilution container, diluting the portion of the oil-in-toluene layer with a toluene dilution volume to create a dilute sample, measuring an absorption value of the dilute sample using a spectrophotometer, and comparing the absorption value to a calibration curve to quantify the amount of oil in the oil-containing fluid.
