Abstract
A method and a device for decontaminating soil on the spot from harmful substances. In the soil one or several horizontally drilled holes (10) are arranged debouching into the ground surface. In the hole a chord (16) is inserted in form of a hose or a number of interconnected sockets, in which reactive sorbents are stored. The chord (16) remains in the ground during a sufficiently long period for achieving a desired decontamination of the soil.
