Intervention measures are actions that seek to eliminate the risk to the safe use of a contaminated area . These actions depend on the type of contamination , its location and intended use of the property , and of course the technical and financial viability for its realization .
The main actions to eliminate the risks and suitability of the areas are divided into the following groups :
Remediation measures : comprises applying one or more technique of removing contaminants in impacted means in stages dissolved , adsorbed or steam so as to achieve concentrations safe for use in an area levels , as determined by evaluation ? risk.
The application technique depends on the characteristics of the contaminated medium (depth , permeability , etc.) and the characteristics of the contaminants (volatility , density , solubility, degradability among others).
When these techniques are applied directly on the site , if called for in situ remediation . The remediation will be called when the ex situ treatment of soil contaminated water or if it goes into the surface or externally to the site , the example is the removal of the contaminated material to be treated in landfills or be incinerated soil.
Once you have studied and understood the place declared as contaminated , are analyzed remediation techniques viable for the area , taking into account factors such as cost -effectiveness , limitations , applicability , efficiency / effectiveness , advantages and disadvantages relations.
Among the methods used , they cite the following :
