B. Description of Equipment. I. Physical Appearance. (a) drilling equipment consists of a well screen placement rig capable of drilling 5 inch diameter borings. Free standing borings are preferred. Monitor wells are 4 inch diameter pipes made of polyvinyl chloride (PVC) with screen slits cut into the length of the pipe. Lances are galvanized pipes fitted with hose attachments. (b) Initialization, propagation and application equipment consists of a plastic mixing tank (500 or 1,000 gallon capacity), gasoline driven pumps, hoses, and applicator nozzles. 2. Unit Size and Transportability. The drilling equipment is fully portable. The initialization, propagation and application equipment, likewise, are fully portable and are easily carried in a small truck. 3. Treatment Capacity (throughput range). The average volume of subsurface contaminate plume treated is 100 cubic yards/mon/day. Therefore, a three man crew can treat 300 cubic yards of subsurface soil per day. The crew continues application until the total contaminate plume is treated. 4. Availability. Equipment is commercially available and is field ready nov. One day of preparation is required before transporting equipment to the site. C. Waste Streams Treated. 1. Contaminants. A aide range of hydrocarbon contaminates are treated by the Bio-Rena Proprietary Bacterial Cultures and Process. Typical contacinates include gasoline, diesel, waste oil, hydraulic fluids, and VOCs (volatile organic compounds), as well as phthalate esters, TCE (trichloroethylene) and DCE (dichloroethylene). Over two hundred hydrocarbon compounds have been identified as being amenable to treatment by Bio-Rem Products and Processes. 2. Problem bastes. Heavy, tight clay-type soils and extremely fine sand slow the bioremediation process and required additional application methods. Ph of soil/water must be in the range of 5.0 to 9.0. Chlorine, Bromine and Fluorine slow the process. Heavy metals dissolved in water, e.g. Chromium, nickel and copper, can halt the bioremediation process. Temperature range for effective use is 38 degrees Fahrenheit to 120 degrees Fahrenheit. If the area of a contaminate plume that is located in the frost area should freeze, it will necessitate reapplication of culture when the affected zone rises in temperature to the useful. range. Areas below the frost level are not affected. 3. Concentrations of Feed and Product Streams. No feed stream is required. The Bio-Rem Process occurs underground and does not require the removal of any contaminated soil. The amount of Bio-Rem Product placed is determined by a proprietary formula and normally is placed only once. Very dry, desert-like conditions may necessitate the gradual addition of water to the contaminate plume and the placement of a vapor-barrier over the site to reduce evaporation.
