MICROBE-LIFT® Technology Helps Remediate TPH Contaminated Soils in Georgia and Tennessee - WASTEWATER TREATMENT
PCS Nitrogen, a business unit of Potash Corporation of Saskatchewan, is one of the largest producers of nitrogen worldwide. It produces nitrogen fertilizers and feed ingredients from three manufacturing facilities in the US and one in Trinidad. When they experienced heavy contamination of soils with hydrocarbon and TPH compounds at two of their facilities, they utilized Ecological Laboratories’ MICROBE-LIFT® technology to remediate these sites.
During 2005, 2006, and 2007, Ecological Laboratories supplied PCS MICROBE-LIFT®, MICROBE-LIFT® /IND, and MICROBE-LIFT®/SA to be used with nutrient management to enhance and speed the remediation process targeting the removal of the petroleum compounds. The bioremediation at two sites, in Georgia and Tennessee, included land farming with monthly bioaugmentation application, followed up by wet lay up over colder winter months with the application of microbial treatment.
These bioremediation programs resulted in site recoveries with dramatic reductions in priority pollutants and TPH. At one site the wet lay up period for three months over the colder period resulted in the reduction of 17 inches of contaminated soil and a corresponding reduction in pollutants, a surprising efficacy considering the low temperature of treatment. It is postulated that the photosynthetic strains in MICROBE-LIFT® provide a substantial advantage in soil remediations.
