Soilutions have gained specialist expertise in bioremediation remediating contaminated soils through a bioremediation process.

Bioremediation is the treatment of contaminated material involving the natural degradation of contaminants by bacteria in an exsitu process. It is one of the most economic remedial techniques presently available for treating organic, fuel based contaminants such as coal tars and liquors, petroleum and other carcinogenic hydrocarbons such as benzene and naphthalene.

The contaminated material is excavated and moved to a treatment area that has been prepared to prevent cross contamination. The material is then aerated and placed into windrows or bio-piles with a substrate being added in the process. The rate of decomposition is greatly increased through the addition of the substrate, which contains nutrients and enzymes, and by controlling moisture, temperature, oxygen and pH levels.

A bioremediation treatment process can typically take from between three weeks to three months. The controlling factors are the type and concentration of contaminates present and the available space for treatment. Generally contamination from heavy fuel oils will take longer to degrade than any lighter petroleum fuel contamination.
