  • In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

    A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...

  • Remediation of polluted river water by biological contact oxidation process using two types of carriers

    Biological contact oxidation technology was used to remediate the polluted river water in Hanyang, China. The purification effect of the polluted river water in three simulated rivers was investigated using two different carriers, i.e., AquaMats made in USA and semi flexible supports made in China. The results showed that when the hydraulic loading rate increased, purification effect in terms of ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • Oxidation v. reduction: how to decide?

    Is in-situ chemical oxidation (ISCO) or in-situ chemical reduction (ISCR) the best option for your site? What factors should be considered to make such a decision? Many chlorinated hydrocarbon compounds (CHCs) can be degraded via oxidative or reductive processes. Accordingly, various ISCO technologies using oxidizing agents such as hydrogen peroxide (Fenton’s chemistry), permanganate, ozone or ...


  • Enhancing in-situ chemical oxidation performance

    In this edition of Peroxygen Talk, guest authors Matt Burns and Bob Pirkle discuss the benefits of compound specific isotope analysis (CSIA) to optimize delivery and monitor performance of ISCO applications. Mr. Burns is a Senior Project Director at WSP Environment & Energy, a leading environmental, energy and sustainability consultancy with over 1,000 people in 65 global locations. He has more ...

  • Soil Reclamation Through Chemical Oxidation

    Supplying ozone (chemical) oxidation equipment to clean soil and groundwater is Kerfoot Technologies' specialty. In the past, contaminated soil was dug and removed to a disposal location. Present-day engineering relies increasingly on smart in-situ technologies with minimal site disturbance. Chemical oxidation is at the forefront of those technologies. ...

  • Case study - Petroleum remediation systems

    Overview A major oil company was looking for a way to stay ahead of EPA regulations for soil vapor extraction of BTEX and the subsequent treatment of these gases. They were looking for one company that could offer competitive pricing, local support service, and the application expertise to provide 50 remediation units throughout the ...

  • Trailer Mounted Afterburner for Soil Remediation

    The Problem A major Vapor & Odor Control company needed a portable solution to clean the soil leftover at old fuel stations. The Process Soil Remediation Afterburners & Oxidizers are manufactured to treat soil containing contaminates such as petroleum hydrocarbons, with diesel oil, gasoline, aromatic hydrocarbons, solvents and many other ...

  • Case study - Mobile remediation system

    OVERVIEW A large consulting and contracting firm owns and operates several ex-situ Thermal Desorption Units (TDUs). Each single-load Thermal Desorption Unit has the capacity of desorbing 15 tons of soil per hour at a temperature of 400°F - 900°F. These Thermal Desorber Units have been designed to operate on both chlorinated and non-chlorinated RCRA, CERCLA, and private industry ...

  • Phytocapping: an alternative technique for landfill remediation

    An alternative technique of landfill remediation known as 'Phytocapping' was trialled at Rockhampton, Australia. Twenty one tree species were established on two types of phytocaps (thick cap; 1400 mm soil and thin cap; 700 mm). The trial was monitored for plant growth, transpiration loss, canopy rainfall interception and methane oxidation. The results show that the tree species can intercept ca. ...

  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix. The Adventus In Situ Bioremediation/Groundwater ...


  • Technology Overview Report: Ultraviolet/Oxidation Treatment

    ABSTRACT This technology report is an overview of information collected by GWRTAC on ultraviolet/oxidation as applied to ex-situ groundwater remediation. Information provided includes an introduction to the principles and techniques associated with this technology, a general discussion of its applicability to remediation, limited cost data relating to results of its use, and advantages and ...

  • Case study - Pemaco superfund site remediation

    OVERVIEW Pemaco was formerly a chemical facility located in a light industrial and residential area of Maywood, CA, adjacent to the Los Angeles River. No one knows how long hazardous substances had been leaking into the ground but the operations date back to the 1940's.  Up until closure of the facility in 1991, chlorinated solvents, aromatic solvents, and flammable liquids had ...

  • 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 ...

  • The effectiveness of arsenic remediation from groundwater in a private home

    Abstract Private wells are the source of drinking water for approximately 15% of households in the United States, but these wells are not regulated or monitored by government agencies. The well waters can contain arsenic, a known carcinogen that occurs in groundwater throughout the nation at concentrations that can exceed the Maximum Contaminant Level defined by the U.S. 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.
