Abstract:
A process for treating a zone of underground hydrocarbon contamination which is at a level above that which is desired comprising the steps of:(A) determining the approximate pH and organic carbon load of the zone;(B) providing a dry powdered mixture of:a) a peroxide of one or more of Calcium, Magnesium, or other metallic peroxides;b) pH adapters to maintain the pH of the fluid in an underground zone to approximately 7 to 9;decomposition rate modifiers; and(C) providing a quantity of water,(D) mixing the dry ingredients with the water to form a slurry;(E) immediately thereafter injecting in situ said slurry into the contaminated underground zone and allowing it to partially or wholely react with the hydrocarbon contamination; and(F) after a period of time, testing the zone to determine the level of contamination and repeating at least Steps (B), (C), (D) and (E) of the process until a level of contamination below the acceptable level is detected by testing.
