Abstract Process for the local treatment of soil in particular for examination and cleaning of contaminated soil The invention relates to a process for the local treatment of soil, in particular for examination and cleaning contaminated soil, in course of which the ample taken from the soil resp. contaminated liquid coming from the contaminated soil or contaminated soil-water are delivered to the surface; prior to delivery or thereafter some treating medium and/or any other material converting the contamination is introduced into the soil intended to be treated or into the contaminated soil. The process according to the invention is characterized in that oblique angled connecting pipes (4,5) resp. a perforated pipe-system (6a,6b) connected thereto, consisting of uniform circuits or streaming circuits, are laid, fitting to the dominant position of the contaminated layer or the layer intended to be treated, so for example occupying a horizontal position, wherein one branch (6a) of the system collects the contaminated liquid, contaminated soil water for further delivery, - 2 - while the other branch (6b) of the system delivers treating medium and/or cleaning media or clean water into the contaminated soil-layer (1). The pipe system consisting of the oblique angled pipes (4,5) and the perforated pipes (6a,6b) connected thereto, is drawn -each single pipe-section (4,6a, resp. 5,6b) in itself- in the bores, having been drilled by known drilling technologie, by pulling back the drilling machine forming said bores, thereafter the bore is starting from the surface, penetrates the contaminated mass of the contaminated soil and after having left the mass it appears on the surface, thereafter the single pipe-sections (4,6a, resp. 5,6b) are connected one by one with the drilling machine.
