  • UXO discrimination using time domain electromagnetic induction

    Introduction An explosive ordnance is a munition that is either launched or fired with the intent of detonation at a specified target. An unexploded ordnance (UXO) is an explosive ordnance that, due to some malfunction, remains undetonated. As a result, the ordnance can be found at the ground surface, partially buried, or buried at a depth of up to 8 m beneath the surface. Practical and ...

  • Combined Remedies Treat Large Industrial Site - Case Study

    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 that resulted in chlorinated volatile organic compound (CVOC) ...

  • Fractured Bedrock Remediation - Case Study

    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 ...

  • PRB Installation at Superfund Site Using Angled Drilling - Case Study

    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 ...

  • Areas Most Prone to Winter Storm Water Can Benefit from Temporary Erosion Control

    Winter can be a beautiful time of year. Generally, there are nice, brief storms and maybe some snow, and everything is fine. But occasionally, we get hit hard with storms that just won’t let up, such as when it rains for days or feet of snow come down—we are left to deal with the consequences. All too often, those consequences involve too much water, despite the work put into ...

  • GoForth, NC Case Study

    ABSTRACT Trap & Treat® BOS 200® was used to remediate petroleum hydrocarbon impacted groundwater within fractured bedrock and overburden soil at a former retail gasoline site in North Carolina. After a thorough remedial design characterization was completed, BOS 200® was surgically injected over two field events to successfully achieve the ...

  • Experimental study on the effect of temperature and flux conditions on moisture distribution in vadose zone soil

    Moisture distribution in vadose zone soil is the most important parameter for land productivity and vegetation status of ecological systems, and is sensitive to temperature variation. In this study, laboratory scale tests were conducted to determine the effect of temperature on variation in moisture distribution in covered and uncovered conditions. The results indicated that soil moisture from ...
