The subject site is a former dry cleaning facility in Northern Europe, where a large tetrachloroethylene (PCE) plume was impacting groundwater on and off-site. In 2017, CAT 100 and BOS 100® were applied as part of a large-scale remediation program. Currently, a 95% average reduction in PCE plume concentrations has been observed in the monitoring wells located in the areas targeted by the remediation.
Abstract: Trap and Treat® BOS 200® was applied at an active gas station in Europe with elevated dissolved phase contamination and NAPL impacts to protect the primary aquifer and cut off the dissolved phase plume from migrating off-site. Over the course of 4.5 years of monitoring, 92.4-99.9% reductions in Benzene were achieved in the treatment area (replaced) monitoring wells. Validation soil s
Trap & Treat BOS 200 was applied at a former retail gasoline site in NYC in 2015 after In Situ Chemical Oxidation (ISCO) was attempted at the site multiple times. A No Further Action(NFA) was issued in 2018 and the property has since been converted from a vacant lot to six story mixed commercial/residential building.
Marshall Iron & Metal in the City of Marshall, Michigan, operated as a railroad maintenance yard from 1899 to 1931 and a foundry from 1938 to 1960. Most recently, it served as an auto salvage/metal scrapyard from 1961 to 1996. Excavation and disposal of soil and debris were completed in the fall of 2015. During these activities, light non-aqueous phase liquid (LNAPL) was observed in an offsite monitoring well. A
Trap & Treat BOS 100 was used to successfully reduce contaminant mass in a localized Trichloroethylene hot spot as part of a pilot test at a former missile site in Nebraska. Over 99% reduction has been achieved in the pilot test well over three and a half years.
The subject property formerly operated as the Retail and Commercial Farm facility. The facility formerly stored and sold feed, farm equipment, and various farming chemicals (fertilizers, herbicides, and pesticides, etc.). In 2015, prior to the potential sale of the property, a Phase I Environmental Site Assessment (ESA) and subsequent Phase II ESA were undertaken. The Phase II ESA identified elevated concentrations of
ABSTRACT
BOS 200® successfully remediates petroleum groundwater impacts in fractured bedrock at a former truck stop. Based on the post-injection groundwater results from the pilot test and full-scale injection, a No Further Action letter was issued in February 2015.
CHALLENGES
Over a period of 20 years, site investigation activities revealed a 320 foot (ft) long dissolved hydrocarbon plume within the fractured bedrock. Light non-aq
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 used in dry-cleaning operations. Approximately one-half mile downgradient of the source PCE (100-300 μg/L PCE) was discharging int
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 apparent pattern. Annual fluctuations in groundwater elevation were significant with changes of up to 14 feet
ABSTRACT
BOS 200® successfully remediated petroleum hydrocarbon impacts at an active retail petroleum facility in Europe, achieving the remediation goal of eliminating vertical migration of impacted groundwater to competent limestone aquifer underlain the site.
CHALLENGES
Site characterization activities following the release identified residual petroleum contaminant mass from 23 to 45 feet (ft) below ground surface (bgs) over 13,0
