  • Direct Hydrogen Addition for the In-situ Biodegradation of Chlorinated Solvents

    As a result of their widespread use as solvents, degreasers, and dry cleaning agents, chlorinated aliphatic hydrocarbons (PCE, TCE, DCE, etc.) represent one of the most common and most persistent groups of contaminants found in groundwater. Characteristically, these compounds exist in the form of DNAPLs in the subsurface making efforts at remediation particularly difficult. In-situ bioremediation ...

  • Extensive remediation of superfund site - case study

    The 80 acre site, formerly a minerals processing facility, was operated primarily to recover lithium and other rare-earth minerals from ores. Raw ores were imported to the site for processing. During one phase of its operations, the facility also processed uranium ores for the government. The site was listed as by the U.S. Environmental Protection Agency (EPA) as a Comprehensive Environmental ...

  • Significant Benefits of Augmenting an Extractive Remedial System with RegenOx™

    Recently, in the United Kingdom, a combined strategy was implemented to synergistically increase the treatment rate and efficiency of subsurface remediation while also reaching an inflexible remedial deadline cost-effectively. Central to this was the novel exploitation of a feature of RegenOx that was initially designed for an alternative purpose. The remedial strategy is now being widely used on ...

  • Explosives remediation at Pueblo Chemical Depot changes course

    Treatment of soil and groundwater contaminated by energetic compounds has been underway since 1997 at area of interest (AOI) 3B of the Pueblo Chemical Depot (PCD) in Colorado. AOI 3B is part of the source of an explosives-contaminated groundwater plume. Initial work involved excavation and onsite composting of soil to address the contaminant source. In 2001, a pump and treat system using granular ...

  • Remediation of BTEX in Groundwater with LNAPL Using Oxygen Releasing Materials (ORM).

    Abstract: A field scale study was conducted at a former gasoline service station to evaluate the remediation of groundwater contaminated with dissolved benzene, toluene, ethylbenzene, and xylenes (BTEX) using oxygen-releasing materials (ORM). The injection of oxygen through ORM slurry was the remedial alternative chosen to enhance the in-situ microbial degradation of the BTEX in groundwater. ...

  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • 8 Years is enough! RPI Group & BOS 100 Tackle PCE problem in Bedrock—Something Finally Worked!

    The Problem: In 2005, a phase I/phase II investigation revealed considerable (as much as 86 ppm in groundwater) PCE contamination at a retail dry cleaning operation. That news was bad enough, but the site sits on karst (clay over limestone bedrock), which meant that drilling, sampling, and installation of any kind of mechanical system or injecting remedial amendments would be a nightmare. ...

  • Pilot tests lead to full-scale ISCO using sodium permanganate in fractured bedrock

    Two-phase pilot testing of in-situ chemical oxidation (ISCO) using sodium permanganate (NaMnO4) was conducted in 2000-2001 at the Tenneco Automotive site in Hartwell, GA, to evaluate feasibility of using ISCO to remediate a dissolved-phase trichloroethene (TCE) plume in a fractured bedrock aquifer [see May 2004 TNT]. The ISCO pilot was initiated to develop an alternate remedy for the off-facility ...
