Date Jul. 11, 1996In a method of cleaning up heavy metal-laden waters and soils, conditions are established in the soils and waters to be treated so that the microorganism present there will form hydrogen sulfide, and optionally apathogenic facultative anaerobes that are tolerant of heavy metals are added to produce hydrogen sulfide, and the hydrogen sulfide formed by microbiological action is allowed to react with the heavy metals to form metal sulfides.
