In-situ method for cleaning soil polluted with halogenated products

摘要

Described is a method for in-situ cleaning of a soil fraction contaminated with halogenated products, in particular with chlorinated products. This method comprises at least the step of introducing an electron donor under substantially anaerobic conditions into the relevant soil fraction. The electron donor herein comprises compost and/or derivatives thereof. In preference the electron donor originates substantially from the first filtrate fraction of compost. This first filtrate fraction comprises liquid released during the first 96 hours after composting.
