Remedial Investigation and Restoration
AbstractDoxaco, LLC retained GeoTech to conduct remedial investigation and restoration of their facility, Transmission King, located in Broward County, Florida. GeoTech was called in response to a discharge of an unknown quantity of transmission fluid and motor oil on the site. GeoTech mobilized to the site to contain, abate and remove the accidental discharge. Discussion and ConclusionGeoTech conducted a visual site inspection, followed by soil and groundwater assessment to determine the horizontal and vertical extent of contamination caused by the discharge. High concentrations of petroleum hydrocarbon contaminants were detected in both the soil and groundwater. Because higher concentrations of petroleum contaminants were found in the soil, GeoTech decided to the remediate the site, via removal of contaminated soils. GeoTech determined the extent of contamination to have affected four individual onsite areas each averaging approximately 24-feet long by 10-feet wide by 7-feet deep. A leak was also identified in an onsite oil/water separator. The source removal activities consisted of: excavation, removal, and off-site thermal treatment of approximately 82.15 tons of petroleum contaminated soils; decontamination, decommision, and removal of a 1,000 gallon onsite used oil tank; decontamination, decommission, and removal of an onsite oil/water separator; and skimming the petroleum free floating product within the excavated area. Based on the results of sampling events following source removal, GeoTech concluded that the scope of the source removal activities had successfully eliminated the contaminant source at the site. Results from sampling events following the source removal indicated that groundwater contamination from petroleum hydrocarbon products were still present in the water table, specifically at the shallow aquifer. However, because the groundwater was believed to be directly impacted by the contamination in the soil and not the oil discharge itself, GeoTech hypothesized that after the soil was removed the wells would naturally attenuate. Following source removal, GeoTech continued quarterly sampling events of the onsite monitoring wells to observe their natural attenuation, until the site was successfully remediated and a No Further Action ruling was granted.

Clean Harbors Environmental Services retained GeoTech to assess the extent of contamination in an area of soil on the side of a road in Broward County, Florida where a truck transporting diesel fuel had caught fire and spilled the fuel into the roadway.
GeoTech mobilized to the site to conduct soil assessments and collect samples in order to determine the lateral, as well as vertical extent of the contamination. The contamination area was identified by GeoTech to be 50 feet long by 17 feet wide by 4 feet deep. GeoTech then collected this approximately 85.83 tons of contaminated soil, about 18 cubic yards for offsite removal. The excavation area was then filled with clean compactable sand, and re-sodded. The contaminated soil was transported to a hazardous waste management facility to be treated with incineration. Final soil screening confirmed that the site had, indeed been successfully remediated. All sampling and disposal of hazardous material was done in accordance with local, county, state, and federal laws.
"GeoTech proved to be a reliable company, as they showed immediate response mobilizing to the site without delay, treating us with the utmost priority...."
