Geo-Cleanse Sponsored and Presented for 2015 Remediation Workshops!
Presentation: Overcoming Site-Specific Challenges with Innovative In-Situ Remediation
Will Moody, Dr. Dan Bryant, and Stephanie Turkot from Geo-Cleanse International, Inc. (Geo-Cleanse) presented at several locations across the United States this past year for the Remediation Workshops. The Remediation Workshops are a series of half-day technical presentations, which provide information regarding the latest soil and groundwater technologies. The presentations provide an overview of the recent advances in environmental remediation, investigation and laboratory analysis for contaminated sites. Not only do these workshops provide technical information, but they are free to attend, and provide networking opportunities and continuing educational credits.
Geo-Cleanse presented on the technology of in-situ chemical remediation, focusing on the following reagents: permanganate, persulfate, hydrogen peroxide and zero valent iron. The presentation provided an overview of each reagent diving into the chemistry, the strengths and weaknesses, and potential applications. Two case studies were provided to demonstrate the effectiveness of this technology and how combining remedies can be more effective for site cleanup.
The first case study discussed a former Brownfield property in Hartford, CT, which was impacted with volatile organic compounds, semi-volatile organic compounds, and extractable total petroleum hydrocarbons, including a light non-aqueous phase liquid (LNAPL). The treatment program for this site consisted of in-situ chemical oxidation (ISCO) utilizing catalyzed hydrogen peroxide and enhanced product recovery to address the vadose and saturated zone impacts. The second case study outlined a former manufacturing facility located in Greenville, SC, which was impacted with high trichloroethene (TCE) concentrations. The site posed significant remediation challenges, including site access (source area on top of a steep hill, plume extending into a wooded area), deep depths (up to 84 ft below grade), hydrology (low permeability saprolite overlying fractured and highly transmissive bedrock), contaminant concentrations (source area TCE concentration as high as 576 mg/L), and a large plume area (over 16 acres). The plan developed to address the site included slurry emplacement of potassium permanganate for ISCO remediation of the source area, coupled with ZVI for in-situ chemical reduction in the plume area.
