General framework for drilling and sampling operations
Diagnosis of polluted sites - Drilling and extraction

In general, drilling and sampling operations are entrusted to engineering firms specializing in environmental soil diagnostics. These companies carry out the historical studies (see [2] , Techniques de l'Ingénieur), define the investigation and analysis program, and organize the drilling and sampling work. They generally subcontract drilling work to specialized companies. In addition to defining the investigation program, the design office's responsibilities include the following:

• ensure that drillers comply with the procedures required for environmental investigations;

• adapt investigations and make decisions based on site...
