  • Pilot-test evaluation for enhanced anaerobic biodegradation of chlorinated ethanes

    In March 2004, an organic substrate mixture was injected through four permanent injection wells at an industrial site to enhance the anaerobic biodegradation of chlorinated ethanes in groundwater. Chemicals of concern (COCs) at the site are the solvent 1,1,1-trichloroethane (1,1,1-TCA), and degradation products 1,1-dichloroethane (1,1-DCA), 1,1-dichloroethene (1,1-DCE), and chloroethane (CA), all ...

  • Green labels: The walk behind the talk - `Biodegradable`

    The word “biodegradable” is probably one of the easiest green labels to understand, so one may assume it is also the least likely to be subject to false claims. However, the term is still interpreted very loosely and frequently used on products that are toxic, that break down into harmful environmental contaminants, or that can take many decades, even centuries, to decompose. On top ...

  • Bioremediation of an Oil Spill

    Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly ...


  • Protocol for Enhanced In Situ Bioremediation Using Emulsified Edible Oil

    An in-depth discussion of the EOS® patented technology and its usefulness for site remediation is presented. Details of how the technology works, design considerations as well as strengths and limitations of the technology are presented. 1.1 INTRODUCTION Management of groundwater contaminated with chlorinated solvents, perchlorate, and explosives is one of the Department of Defense’s (DoD’s) ...

  • 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 ...

  • Break It Down, Build It Up - Sustainable Science Has Roots in ASTM Standards Development

    It was back in the 1980s,” Richard Wool, Ph.D., recalls. “A lot of waste management sites were running out of space. Barges full of garbage were plowing up and down the East Coast with no place to dock. The idea of having biodegradable plastics would address a number of issues like getting rid of the trash and cleaning up marine waste, which was becoming a huge issue at the ...

  • Generation using gas-fuelled engines in South Africa – an overview

    Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, ...
