Marathon Oil Corporation (Marathon) retained EIC to perform recovery
potential tests to evaluate the feasibility of recovering non-aqueous
phase liquid (NAPL) at a former terminal and warehousing facility in
the Chicago metro area. Although Marathon had implemented
various remedial measures, including pumping systems and excavation of
NAPL-saturated soil, NAPL continues to persist at this site. EIC will
utilize its unique non-aqueous extraction technique (NETTM)
- based system to perform recovery recharge tests to determine the
NAPL recovery potential from selected wells. In particular, the
tests will determine if NAPL recovery is sustainable or limited.
If found sustainable, the NETTM systems can be utilized to
match recovery to recharge thus optimizing NAPL recovery until an end
point is reached. The remedial progress and end points can be
verified utilizing EIC's patented Groundwater Factoring Technique (GFT).
If NAPL recovery is limited, alternative remedial measures will be
considered. This approach will help Marathon eliminate
perpetual NAPL liabilities in a cost-effective manner and within a
reasonable time frame. Marathon authorized this task for EIC
under a subcontract agreement with Arcadis.
