Pollution Engineering - March 2009 - (Page 25) Getting Rid of FOREIGN OIL How to select in-situ injection technologies for remediation of hydrocarbons. By STEVE KAHN, LT Environmental Inc. T he environmental site assessment and remediation industry is relatively new and dynamic, and like any new field, innovations are rapidly altering processes and techniques utilized to achieve site cleanup and closure. Recently, new methods and innovative technologies, designed to treat contaminants in-situ via injection of slurry mixtures, are gaining recognition in the environmental remediation field. The system uses discrete chemical and/or biologically based injections, as opposed to a permanent infrastructure. Remediation is accomplished with a direct-push drill rig, injectate, mixing tanks and pumps. Cleanup can be accomplished in a matter of weeks or months, as they do not require the same semi-permanent piping infrastructures, equipment compounds, onsite technicians, utility connections and permits. One of the most critical factors in successfully installing an injectate is overcoming delivery challenges, i.e. getting the treatment reagent to the subsurface impacted area such that adequate contact is made (between injectate and solute/ contaminant) to achieve targeted concentration reductions. The science behind these technologies is sound, but successful full-scale implementation beyond the laboratory necessitates a proper three-dimensional distribution of injectate in the subsurface. In order to achieve a successful design, a thorough site conceptual model is required relative to other remediation technologies. Identification of geologic heterogeneities and a quantitative understanding of the contamination profile are crucial. A haphazard approach of injecting a variety of injectates without developing the site conceptual model ultimately will lead to either project failure by under dosing a site, or cost Direct push exploration and injection systems can be faster than traditional drilling methods. Also, they can be used in restricted areas such as shown above where the overhead wires would be a problem. MARCH2009 www.pollutionengineering.com 25 http://www.pollutionengineering.com
