International evaluation of in-situ biorestoration of contaminated soil and groundwater (September 1990)
The philosophy of in-situ biorestoration is to stimulate the indigenous soil microorganisms to degrade contaminants by improving the environmental conditions in the soil using a water recirculation system. The objective of the project is to show the possibilities for application of the technique in relation with contaminants, soil conditions and other site-specific circumstances by means of integration and evaluation of results of in-situ biorestoration projects. The project is limited to the Netherlands, West Germany and the USA. Experience has especially been gained with in-situ biorestoration at hydrocarbon-contaminated petrol stations and industrial sites. The system generally consists of a water recirculation system, aboveground water treatment and conditioning of the infiltrating water with nutrients and an oxygen source. However, there is no one-and-only application method for in-situ biorestoration. The remediation, which can last from approximately six months to several years, can reach residual concentrations below the B-value of the Netherlands examination framework.
