Dear Hivers
Pumping and treatment
For depollution to be complete, pumping is essential. Here, it will not be a question of using a truck or a cistern, but small equipment to pump the water tables. The expert will use a submersible pump or a vacuum pump for the contaminated parts. For treatment, it is done gradually especially when it comes to water.
Depollution by biological processes.
Professionals do not use it much because it has a slow healing even if certain plants have been proven to have assets that can help depollution.
Depollution by physico-chemical processes
It is rather in this direction that the professionals of remediation are heading, because these are chemical processes having been the subject of a physical test and having more values in their eyes. In a nutshell, this method will consist of injecting gas or liquid into the contaminated soil. Thereafter, an extraction is made by aspiration.
Other types of depollution.
Depending on the site assessment that has been carried out by the professional, there may be gentler and easier ways to clean up hydrocarbons. But in the event that the situation proves to be more difficult or more sensitive, other processes, apart from those we have mentioned, can help. Biostimulation, in situ oxidation… There are many techniques, but the most frequent is that of the use of physico-chemical products.
Why hire a professional for depollution?
The learning that we had at school concerning the soil and its surroundings is not enough to master depollution. Indeed, even just at the site assessment level, it is necessary to have extensive knowledge to draw up the plan of attack that will suit the situation. A professional will have the skills and qualities that will be required to carry out the work without fault and without the contamination spreading elsewhere.
