Ex Situ Soil Remediation

Ex situ treatment of soil involves excavating the impacted area and then treating the excavated materials on site. Treatment can include a wide range of methods including biopiles, stabilization, ex situ oxidation, and soil washing. The process can include permitting, excavation and backfill, construction and decommissioning of lined treatment cells, mixing and aerating, as well as other forms of treatment.

The treated materials can either be reused on site, if applicable, or removed off-site to an appropriate licensed site. The advantages of ex situ treatment are that it can eliminate or reduce the off-site transportation and disposal of impacted materials, or reduce the end cost of off-site disposal by effective pre-treatment.
