Keynote: Remediation of Petroleum Hydrocarbon Impacted Site - Technology Trends Past Present and Future
Trevor Carlson, Principal, Geosyntec Consultants, Saskatchewan, Canada
Over the past 30 years, environmental professionals have experienced and ever evolving toolbox of technologies to manage petroleum hydrocarbon impacted sites. Management trends have progressed from excavation and landfill to mechanical extractive technologies, chemical oxidation, thermal techniques and bioremediation approaches. Each of these approaches have their place. There is no single option that is best. This presentation will discuss that the key to success begins with defining success, knowing when to use each approach and when to transition from one approach to another and knowing when you have reached your defined endpoint.

Source Zone Surfactant Flushing and Dissolved Phase Bioremediation
David Alden, P.E., Manager, Technical Services, Tersus Environmental, Worcester, MA, USA
Join David for a short overview on how to determine viability for a surfactant flood and how this technique is combined with ISCO and biostimulation for the remediation of petroleum hydrocarbons. We will go through basic design considerations and how to come up with ballpark costs during feasibility studies. Surfactants, solvents and polymers can physically remove petroleum hydrocarbons sorbed to the soil matrix. With adequate hydraulic control, this method is very efficient at contaminant mass removal which in turn allows polishing techniques such as ISCO, BIO and MNA to be more effective. Selection of a potential polishing technique should be considered early on in the project with help of geochemical parameters. The presentation will review surfactant flood and bioremediation design methods and highlight results and lessons learned from various projects.

Horizontal Directional Drilling and Well Installation for Substrate Injection
David S. Bardsley, P.G., SeniorGeologist, Directed Technologies, Scottsdale, AZ, USA
Horizontal wells can be an effective tool for emplacement of substrates for remediation activities. However, the most frequent concern among injection experts is “won’t all the injectate come out in the beginning of the well?” By reviewing conservation of mass, friction loss, including losses across individual slots, the well open area (slot pattern) can be designed to insure equal flow rates. In other words, each horizontal injection well has a project specific screen design. This presentation will detail proper drilling and well installation techniques along with a screen design case study.

Sandra Dworatzek, M.Sc.
Principal Scientist, SiREM
Ms. Dworatzek is an environmental microbiologist with advanced technical experience in laboratory treatability studies. Over the past 25 years she has conducted and overseen numerous bench-scale studies examining enhanced in situ bioremediation in groundwater. She has specific technical experience in the design of laboratory treatability studies, the scale up of growth of aerobic and anaerobic microbial cultures for bioaugmentation laboratory and field pilot tests, and evaluation of aerobic and anaerobic bioremediation, zero valent iron and chemical oxidation technologies in the laboratory. Ms. Dworatzek is a Principal Scientist at SiREM and has been with the company for over seventeen years. SiREM maintains state-of-the-art treatability, molecular testing and microbial culture production facilities. She currently oversees maintenance and culturing of KB-1® and KB-1® Plus dehalorespiring microbial cultures that have been widely used in field demonstrations to improve the rate and extent of bioremediation of chlorinated solvents in groundwater (e.g., tetrachloroethene (PCE) and trichloroethene (TCE) dechlorination to ethene), as well as the development of new bioaugmentation cultures including 1,4-dioxane, 1,2,3-trichloropropane, benzene, toluene and xylene. She provides technical oversight for treatability studies for a wide range of environmental contaminants, including halogenated organics (e.g., solvents, pesticides, etc.), both alone and in complex mixtures.
