Former industrial sites often involve pollution transfer through groundwater. In these cases, removal or control of the sources is insufficient and action on groundwater flow is required. Sol environment designs and implements tailor-made solutions in this area, based on its signature techniques and 20 years of project experience in France and worldwide.
