Combining Traditional and Advanced In Situ Remedial Methods to Address Source Petroleum Hydrocarbon Mass
William Moody, Director of Business Development, Provectus Environmental Products, Inc.
An in situ remedial plan was developed to address source contamination at a former automotive service station. Historical site operations, specifically the use of underground storage tanks had impacted the aquifer with petroleum hydrocarbon contamination. The USTs were removed along with soil impacts; however, excavation was limited due to the depth of contamination, buildings and a road. Free-phase hydrocarbon was present in several wells with enhanced fluid recovery implemented to remove the free product to the extent practical. The site is currently an active auto body shop that is connected to other businesses. An aggressive (i.e., ISCO) and sustained (anaerobic bioremediation) remedial method was desired to address the residual petroleum hydrocarbon mass. Based on the site conditions, a total of 8,500 lbs of ferric iron activated persulfate was applied via direct push slurry injection. Information on the reagents mode of action, dosing requirements, and lessons learned during the field implementation will be presented along with results from performance monitoring.
Mr. Will Moody is an environmental scientist with 15 years of professional experience focusing primarily on in situ remediation technologies to address soil and groundwater contamination. Mr. Moody received a Bachelor of Science Degree in Environmental Science from Virginia Polytechnic Institute and State University (Virginia Tech). He began his professional career as an environmental consultant, which was followed by over 10 years of in situ remedial design and field implementation at an international remediation firm. Mr. Moody’s laboratory and field project experience includes the application of a wide range of in situ solutions including chemical oxidants, chemical reductants, and surfactants to address common (e.g., BTEX, chlorinated VOCs, etc.) and emerging contaminants (e.g., 1,4-dioxane and Freon). His experience includes the utilization of zero valent iron, hydrogen peroxide, sodium/potassium persulfate, sodium/potassium permanganate and other site-specific reagents in overburden and bedrock systems. In August 2017, Mr. Moody accepted the position of Director of Business Development with Provectus Environmental Products, Inc. to continue to work within the in situ remediation field with several advanced and novel technologies.
