  • World Oil: Proppant-sized solid inhibitors improve flow assurance in fraced wells

    The economic value of a hydraulically fractured well is highly dependent upon flow assurance—that is, maintaining unimpeded flow of hydrocarbons from the formation to the surface. Flow assurance issues occur in hydraulically fractured wells, as a result of the deposition and buildup of naturally occurring particulates that are present in the system during hydrocarbon production. Scale is ...

  • Metagenomic approach to characterize soil microbial diversity of Phumdi at Loktak Lake

    Loktak, one of the largest freshwater lakes of India, is known for floating islands (Phumdi), being made up of a heterogeneous biomass of vegetation and soil. This ecological site represents an exclusive environmental habitat wherein the rhizospheric microbial community of Phumdi plays a key role in biogeochemical cycling of nutrients. A culture-independent whole genome shotgun sequencing ...

  • Superfund Remediation: The Key to Land Reuse Case Study

    The technology is ready and, with state and federal tax credits waiting, the economics look better than ever: New Jersey, one of the first states to be industrialized, finds itself plagued with the contaminated aftermath of pre-EPA industries: soil contamination. From superfund sites to the gas station whose underground storage tank has been oozing for the last 20 years, every ...

  • Case study - Groundwater remediation of a contaminated site using enhanced anaerobic bioremediation

    Chlorinated solvents are a common threat to drinking water sources throughout the United States. While handling and disposal practices today are more closely regulated and monitored, this has not always been the case. With dry cleaners using tetrachloroethene (PCE) and industrial manufacturing facilities commonly using a variety of solvents from trichloroethene (TCE) to methylene chloride, past ...

  • Application of horizontal-flow anaerobic immobilized biomass reactor for bioremediation of acid mine drainage

    The production of low-pH effluent with sulfate and metals is one of the biggest environmental concerns in the mining industry. The biological process for sulfate reduction has the potential to become a low-cost solution that enables the recovery of interesting compounds. The present study analyzed such a process in a horizontal-flow anaerobic immobilized biomass (HAIB) reactor, employing ...

  • Enhanced Anaerobic Bioremediation of a TCE Source at the Tarheel Army Missile Plant Using EOS

    EOS, or emulsified oil substrate, was used to stimulate anaerobic biodegradation of trichloroethene (TCE) and tetrachloroethene (PCE) at a former Army-owned manufacturing facility located in the Piedmont area of North Carolina. Previous use of chlorinated solvents at the facility resulted in soil and groundwater impacts. Ten years of active remediation utilizing soil vacuum extraction and air ...

  • Learn why All Zero-Valent Iron (ZVI) Remediation Products are not the same

    The MAJOR DIFFERENCE between Emulsified Zero-Valent Iron (eZVI) and other ZVI products is the physical structure of the eZVI product, which is a water-in-oil emulsion (see below images). This structure makes the eZVI product hydrophobic, and therefore it is fully miscible with source material in situ. The water contained in the interior of the eZVI emulsion provides the hydrogen for abiotic ...

  • Drawing the Line between Water Damage Restoration and Mold Remediation

    Background of Water and Mold Damage In recent years, many insurance policies have instituted limits or caps on the amount that will be paid for “mold or microbial damage.” Often, what constitutes microbial damage is defined poorly, if at all, in the policy. Meanwhile, the funds available for water damage restoration are generally not separately capped, and are available up to ...

  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...

  • A Word About Competition...

    Almost three weeks ago, the RPI Group running team successfully nailed our 5th consecutive Bourbon Chase 200-mile relay race in Kentucky. Needless to say, we love to compete! Competition is the engine that drives the global economy. It’s kind of cool that a few companies are trying to imitate our products and our approach to in situ remediation – that’s probably the best ...

  • Controlling Methane ar ERD and ISCR Applications

    In situ chemical reduction (ISCR) and enhanced reductive dehalogenation (ERD) have demonstrated success in the remediation of numerous recalcitrant and toxic compounds, including chlorinated ethenes and hexavalent chromium.  ISCR describes the combined effect of stimulated biological oxygen consumption (via fermentation of an organic carbon source), direct chemical reduction with ...

  • Evaluating Risks to Wildlife from Coal Fly Ash Incorporating Recent Advances in Metals Risk Assessment

    Current scientific advances in metal/metalloid risk assessment were applied to evaluate risk to aquatic and riparian wildlife species potentially impacted by residual coal fly ash after clean‐up of an unprecedented large ash release into an aquatic environment, the first assessment of its kind. Risk was evaluated using multiple lines of evidence (LOE) including (1) tissue‐based risk assessment ...

  • Comingled Plume? No Problem!

    CGRS Environmental Services and RPI Group Approved Installer, Vista Geoscience, were a bit surprised at what happened recently at a Denver hydrocarbon site they were remediating with Trap & Treat® BOS 200® injections. In late 2011, PCE contamination was also discovered (most likely coming from an upgradient dry cleaner). The client stated “The data shows that the BOS 200® ...

  • Insitu mixing of dry and slurried reagents in soil and sludge using shallow soil mixing

    Introduction Recent implementation for the Federal Hazardous Waste Land Disposal Restrictions (LDR) to RCRA and USEPA's willingness to approve on-site treatment and/or containment has allowed in situ treatment methods to become viable options in site remediation. Shallow Soil Mixing (SSM) is one of several in situ mixing techniques now commercially available for use in on-site treatment of ...

  • ST. Thomas, USVI diesel oil spill soil remediation project case study

    The Problem Staff at a major four-star resort outside St. Thomas in the US Virgin Islands spilled diesel fuel and kerosene during the transfer from a tanker truck to on-site storage tanks. Approximately 67.3 m3 of soil having an average concentration of 12,000 ppm was contaminated. Because there are no treatment facilities on the Island, the resort was facing significant costs to transport ...
