A method of purifying hydrocarbon polluted soil. The polluted soil, mixed with water and air, is sucked into a conduit. Meanwhile, water under high pressure is ejected from a jet pipe as a substantially conical water curtain. The sucked-in soil is then passed through the water curtain, which removes the pollutants, and the thereby-purified soil-water mixture is ejected.
