Using in-house resources, Sovereign handles all phases of investigation, remedial strategy selection, engineering design, permitting, system installation, operation, maintenance, optimization, and closure at the site. Sovereign conducted site-wide soil and groundwater characterization and developed Corrective Measures Implementation Plans for three areas. Sovereign conducted capture zone analysis at one area of the site and designed an intercept well system to enhance hydraulic control and prevent VOC migration.

Sovereign designed and installed a soil vapor extraction system to remove carbon tetrachloride,. Sovereign operated the system for 14 months and achieved non-detect levels for carbon tetrachloride. Three months later, ADEM granted No Further Action. By selecting the right technology, Sovereign greatly reduced life-cycle project costs.

For in-situ chemical oxidation with modified Fenton’s reagent at one AOC, Sovereign prepared permits, coordinated bench-scale testing, supervised the installation of a network of injection wells, designed the injection manifold, and conducted in-situ oxidation using quarterly batch injections.
