ABSTRACT Trap & Treat® BOS 200+® was applied using direct push technology (DPT) methods at a former retail gasoline site in Knoxville, TN. Since installation, there has been a 57-99% reduction in total BTEX, a 42-99% reduction in naphthalene, and an average increase of almost 200%...
ABSTRACT Trap & Treat® BOS 100® was injected in shale fractured bedrock at a corporate site in New Jersey in 2018. The Classification Exception Area /Well Restriction Area (CEA/WRA) was removed 25 months post-injection after achieving New Jersey Ground Water Quality Standards (GWQS). CHALLENGES The site...
ABSTRACT BOS 100® was successfully implemented as part of a combined remedies strategy to treat elevated levels of chlorinated solvent DNAPL (Trichloroethylene) in a shallow fine grained aquifer at a former large industrial facility. BACKGROUND Historical industrial property that utilized chlorinated solvents for equipment maintenance from the 1950s...
ABSTRACT Trap and Treat® BOS 200® was applied at a site in a Permeable Reactive Barrier (PRB) configuration to manage offsite petroleum hydrocarbon contaminant flux and replace a non-performing existing PRB. Project objectives were realized within 6 months of installation. PROJECT SNAPSHOT • PRB Dimensions = 80 ft...
ABSTRACT Trap & Treat® BOS 200® was used to remediate petroleum hydrocarbon impacted groundwater in shallow overburdened soil at a former retail gasoline site in southern California. After a thorough remedial design characterization was completed, BOS 200® was surgically injected to successfully achieve the site cleanup...
ABSTRACT High density sampling program was key to remediation of soil and groundwater impacted by TCE DNAPL at a former industrial site underlain by river deposits and sedimentary bedrock. CHALLENGES Impacted alluvium consisted of poorly sorted, fine to coarse grained sand. The source area was underlain by an...
ABSTRACT Carbon Tetrachloride source in bedrock and collateral contamination in overburden were successfully remediated at a decommissioned U.S. Air Force base. CHALLENGES The combination of bedrock and overburden Carbon Tetrachloride (CT) contamination posed a unique set of challenges including the selection of an adequate drilling program, gathering critical...
ABSTRACT BOS 100 was successfully implemented as part of a combined remedies strategy to treat elevated levels of Trichloroethylene in a shallow fine-grained aquifer at a former large industrial facility. CHALLENGES A large industrial facility used vapor degreasing in the 1970s and 1980s, which resulted in the contamination...
ABSTRACT BOS 200® was injected at a refined petroleum product terminal to remediate LNAPL in groundwater. Within one year after treatment, the site received a No Further Action status. CHALLENGES The remedial goal was to eliminate the reoccurrence of light non-aqueous phase liquid (LNAPL) which persisted with no...
ABSTRACT BOS 100® was injected adjacent to and beneath a stream using a direct push angle drilling technique to successfully create a PRB and limit PCE flux from the upgradient source area into the stream. CHALLENGES The Superfund site is a former textiles facility where tetrachloroethylene (PCE) was...
