Services Provided: Soil pollutant analysis; microbial isolation screening and selection; inoculum design, testing and bioaugmentation; Ecopile design, consultancy during construction, inoculation and monitoring (moisture, nitrite, sulphate, ammonium, organic matter, BOD/COD, surface); phytocap selection, implementation and monitoring (biomass, root and shoot analysis, total viable counts), TPH and PAH reduction, GC-FID analysis and monitoring.

Result: TPH was removed to safe levels and all monitoring parameters measured returned to their optimal pre-contamination levels including soil pH and normal microbial populations. As the selected inoculum consisted of natural isolates and as TPH degraders reduced in consistence with as pollutant reduction this was the ideal treatment process in an environmentally sensitive area.
