Abstract
A system for treating soil contaminated by petroleum hydrocarbons which comprises applying a suitable bacterial culture capable of degrading petroleum hydrocarbons in a dry form to the bottom of an excavated cavity, applying gravel to a suitable depth over said dry cultures, providing a system of distribution piping capable of supplying nutrients directly to said cultures, and also an air flow through the area containing said cultures, and placing the appropriate tank in place within said cavity and covering with gravel and dirt. The system is activated by providing said cultures with a source of nutrients through said piping followed by flowing air through the piping to facilitate metabolization of the hydrocarbons contained in the soil.
