While working for a joint venture between Stillwater Technologies, E Sciences, Mr. Cook managed a staff engineers and geologist who designed and supervised the installation of the longest horizontal biosparge system known to have ever been installed in Florida. The 1000-foot-long sparging system, which using the injection of air through a series of underground pipes to remove hazardous contaminants from soil and groundwater, was installed at the site of a former underground fuel storage tank at O.C. Fire Station 20, located in Apopka, Florida. The system pumps over 400 cubic feet of air per second through the contaminated soil and groundwater. The remediation process remained in operational until the contaminants in the soil and groundwater are reduced to levels that are safely below state-mandated thresholds. At that time, a natural attenuation monitoring plan was conducted for one year to ensure contaminants remained below cleanup levels.
