Water samples from the river upstream and downstream were carried out by the French Biodiversity Office and must be analyzed by an independent laboratory.
A study office mandated by SNCF network must take samples from the soil surface and a geological study by piezometer must allow a "more precise analysis of soil pollution but can only be set up once the handover operations have been completed. in condition of the completed tracks ”.
