Challenge:
- Solve the contamination (Cis-DCE and VOCs in groundwater) and make them compatible with the construction works according to the client's needs.
Solutions:
- Groundwater treatment.
- Treatment: In collaboration with the SARPI Remediation France team, the project was designed in 2 phases:
- 1st Phase: ISCO, through 2 injection campaigns at 88 points.
- 2nd Phase: Pump & Treat with the installation of a treatment plant (Air stripping + active carbon filters) with a capacity of 20 m3/h and reinjection of the treated water into the aquifer to keep the water table stable during the excavation work and construction.
- Total Area: 21.500 m².
- Pump & Treat: 61.800 m³.
