Process for the local treatment of soil in particular for examination and cleaning of contaminated soil
First Claim
1. A process for treating contaminated soil in-situ without demolishing the contaminated soil or structures situated above the contaminated soil comprising:
- a. using a pipe system comprising at least two branches;
a first branch comprising a first oblique angled connecting pipe connected to a first perforated pipe positioned in a first oriented drilled boring in a direction in compliance with dominant position of a layer of contaminated soil;
the boring in which said first connecting pipe and first perforated pipe are situated is drilled without any breaking-point from a first location on the earth'"'"'s surface to a second location on the earth'"'"'s surface;
a second branch comprising a second oblique angled connecting pipe connected to a second perforated pipe positioned in a second oriented drilled boring in a direction in compliance with dominant position of the layer of contaminated soil;
the second boring in which the second connecting pipe and the second perforated pipe situated is drilled without any breaking-point from a third location on the earth'"'"'s surface to a fourth location on the earth'"'"'s surface;
b. introducing into said first branch a medium for treating the contaminated soil layer, said medium reaching the contaminated soil layer through the perforated pipe connected to the oblique angled connecting pipe; and
c. bringing to the earth'"'"' surface through the second branch contaminated liquid or contaminated soft-water drained off from the second perforated pipe through the oblique angled connecting pipe.

Abstract
A process for the treatment of soil in situ involving examination and cleaning of contaminated soil. Treating medium and/or any other material for treating the contamination is introduced into the soil intended to be treated. The process involves the use of oblique angled connecting pipes which are connected to a perforated pipe-system fitting to the dominant position of the contaminated layer or the layer intended to be treated. One branch of the pipe system collects the contaminated liquid and/or contaminated soil water and brings it to the earth'"'"'s surface. The other branch of the system delivers treating medium to the contaminated soil. Optionally, the contaminated liquid or contaminated soil-water can be cleaned and reintroduced into the same branch of the pipe system into which the treating medium is introduced.
