SURFAC® Implementation and Results

BackgroundSPH (gasoline) was historically present in five monitor wells. SPH ranged from0.01 to 0.98 feet in five monitor wells during six EFR® events conducted from May2006 to April 2009, covering an area of approximately 5,000 square feet.

Hydrogeology

Groundwater is present in saprolite, consisting of various amounts of silt, sand,and clay, at depths of approximately 30 to 35 feet below grade.

SURFAC® Treatability Study

• A SURFAC® treatability study identified and optimized the concentrationsof the most compatible surfactant/electrolyte mixture and applicationvolume.• The study also verified that EcoVac ’ s Formulated Surfactant wascompatible with the site groundwater.

SURFAC® Implementation

• A single SURFAC® application was conducted at the subject site fromJune 7 to 11, 2010 (5 field days).

Results and ConclusionsSPH was not detected at the site following SURFAC® implementation.No Further Action Required (NFA) was achieved at this site.

BackgroundSPH (diesel fuel) was historically present in seven monitor wells ranging inthicknesses from 0.01 to 2.74 feet. SPH thicknesses have been very erratic at thissite due to the possibility of “trapped” SPH being liberated during water tablefluctuations. Previous remediation efforts were unsuccessful, including excavationactivities and four mobile dual-phase extraction events conducted by anotherprovider.

HydrogeologyGroundwater is present in saprolite, consisting of various amounts of silt, sand,and clay, at depths of approximately 15 to 22 feet below grade.

SURFAC® Implementation

• EFR® and SURFAC® pilot test events were conducted on January 10,2007, October 22, 2007, November 13, 2007, and January 23, 2008.

• These events were conducted at the site to1. Achieve contaminant removal2. Reduce the aerial/vertical extent of the plumes3. Determine the surfactant injection volumes/locations/sequence4. Determine the duration of the surfactant injection/capture events.

• A single SURFAC® application was conducted at the subject site fromAugust 18 to September 19, 2008 (six field days).

Results and ConclusionsSPH was not detected at the site following SURFAC® implementation.No Further Action Required (NFA) was achieved at this site.
