Munox SR bioaugmentation remediated petroleum seepage on a Caribbean Island by NRG Save of Toronto. For several years on-going surface seepage from a crude petroleum leak was collected in a pit to prevent further surface flow. Recently, Munox SR was added to the pit and to the ground surface. After 6 days the water in the pit was visibly cleaner. After 12 days laboratory tests of the water in the pit showed the total petroleum hydrocarbons and oil and grease were below detection limits.
