Transitioned one of the three areas into a monitored natural attenuation program
Evaluated groundwater remedies for the third area through the use of one, two, and three-dimensional groundwater models that included:
- Natural attenuation
- Injection of reactants with a parallel evaluation of limitations due to hydraulic fracturing potential
- Groundwater flow barrier with an enhanced biowall treatment gate
- Pump and treat methodologies
Submitted a Focused Feasibility Study (FFS) for the third area and the clients are awaiting regulatory approval of the preferred remedial alternative.
