Project scope and field context
Spellman Superfund Site, City of Orlando, FL The Ambient Technologies Drilling Team completed Direct Push Technology (DPT) Drilling, Soil & Water Sampling, Installation and Abandonment of Monitoring Wells, and Injection Points for Remediation, at a Superfund Site in the City of Orlando, Florida. The Former Spellman Engineering property is located northeast of Lake Highland, Orlando, Orange County, Florida. The site includes light industrial, commercial, and residential properties. Spellman Engineering was a parts cleaning business that operated from approximately 1963 to 1969. The purpose of the investigation was to identify and delineate the nature and extent of industrial solvents in the soil and groundwater at the site. The Scope of Work included 20 Soil Borings (direct push continuous macrocores sampling) to a depth of 60 ft, 19 Injection Points at 3 depth zones with approximate depths at 40 ft, 50 ft and 70 ft, and GW sample points up to 70-ft below land surface. The remediation mixtures were made on site and nearly 600 gallons were injected at each interval. This second phase also included the installation of 5 monitoring wells (vertical and angled) were installed at depths of 40 ft, 50ft and 70 ft. for continuous monitoring of the following phases of the project. Soil Borings were grouted and patched once completed. Monitoring Wells required development of up to 30 minutes. The key contaminant at this site is Trichloroethene (TCE). Using a Geoprobe 7822DT, and a Geoprobe 7730DT Ambient Technologies was able to accomplish the required Scope of Work within the time and budget allocated to this secondary phase of the Spellman Site Project. GeoView, Inc., a wholly owned subsidiary of Ambient Technologies, provided private utility clearance for all soil borings, monitoring wells and injection wells. Project Services: 20 Soil Borings (direct push continuous macrocores sampling) and GW sample points up to 60-ft below land surface. DPT installation of 19 Injection Points to depths of 40 ft, 50 ft, and 70 ft. The remediation mixtures were made on site and nearly 600 gallons were injected at each interval. DPT installatiion of 5 Monitoring Wells to 30 ft, 50 ft and 70 ft. Wells are 1.5" with 10 ft of prepack screen (0.010 slot and 20/30 filter sand) with quicksleeve bentonite seal and foam bridge. Hand clear to 5 ft and macrocore to TD (if needed) Complete all wells with 2'x2'x4" concrete pad and 8" bolt down cover. Decon pad construction. Abandonment of 3 Monitoring Wells, 2 inch down to 30 ft. Pad/cover removal and resurface. GPR borehole clearance performed by GeoView on each location
