Fast, Low-Cost Petroleum Spill Treatment

After removal of USTs, ground water was treated over a one-half acre plume in Houston, Texas.  Petrox bioaugmentation was implemented by injection of 110 gallons of high concentration microbial solution in April 2006.  Post-treatment sampling shows the bioaugmentation significantly reduced the source area contaminant levels  at a cost of less than $2,000 for the Petrox®.
