<P>PROBLEM TO BE SOLVED: To efficiently purify soil or ground water contaminated with organic compounds such as oil by adding a nitrogen-containing nutrient and a phosphorus-containing nutrient to the soil or the ground water. Ž<P>SOLUTION: In a method for purifying the soil or the ground water contaminated with the organic compounds by adding the nitrogen-containing nutrient having an ammonium group and the phosphorus-containing nutrient to the soil or the ground water, part of the soil or the ground water is sampled. The nitrogen-containing nutrient in an amount of 1/60-1/15 (nitrogen-converted weight) of an oxygen consumption or the amount of generated carbon dioxide when the organic compounds are oxidatively decomposed by microorganisms contained in the sample is added into the soil or the ground water.
