Munox SR bioaugmentation remediated oil seepage on a Caribbean island to protect local natural resources. On-going seepage was collected in a pit to prevent further surface flow. A small amount of Munox SR was added to the pit and to the ground surface where the seepage was occurring. After 6 days the water in the pit was visibly cleaner. Laboratory analysis confirmed the decrease in oil and grease. After 12 days the floating oil layer was gone and laboratory tests showed that the Munox SR organisms reduced the total petroleum hydrocarbons and oil and grease to less than detection limits.
