5. Pilot-scale experimentation
Laboratory tests are used to determine the scientific basis of the technique (which oxidant, what proportions), while the on-site pilot is carried out under real conditions, over a small area. Pilot tests are designed to settle a number of dimensional and more technical aspects. Pilot testing is an essential complement to laboratory testing. Depending on the type of environment and the type of oxidant used, the duration of a pilot test (oxidant input and follow-up) is one to three months.
5.1 Pilot for slick decontamination
For an on-site pilot, the first objective is to determine the radius of influence. It is indeed important to determine the mesh size of the injection wells. The second question is that of monitoring the reaction: which parameters will reflect...

Regulations
There are no specific regulations governing soil and aquifer treatment techniques. The decree of 17/07/09 on measures to prevent or limit the introduction of pollutants into groundwater specifies that the introduction of certain substances into the environment is prohibited. These substances are listed in appendices 1 and 2. However, a paragraph specifies that :
