t <br /> n <br />..rr <br /> (C) 1939 BIO NATIONAL CORPORATION <br /> n.. <br /> 7 TREATMENT OF CONTAMINATED CUTTINGS <br /> t z These may be open aerated per local regulations, and the soil disposed of as <br /> landfill on site. However, we will place the material in plastic lined steel <br /> dumpsters. <br /> tr <br /> The sail will be treated with a 20-3096 Esturation level o; watery inoculum of <br /> our BIO/100 microbes. A perforated venting pipe will be placed in the middle <br /> of each dumpster, and slaved into the V/E unit for enhancing the aeration <br /> f process. We expect that procedure to last no more than 21 days. <br /> By:using this approach, we are containing vapors that might escape into the <br /> �.x atmosphere, however well within acceptable limits, and enhancing the <br /> { i bioremediation process of the cuttings at the same time. <br /> r 6 The soil will be suitable for on site landfill or disposal at a Claes IYI dump. <br /> 8 S7ST13M CONTROL <br /> The Bio National In Situ Bioremediation System has numerous built in control <br /> i:•. <br /> factors that assure safety and simplicity of operation. Thess will be listed as <br /> follows, but the primo element is the natural microbial process itself. <br /> 8.1 NATURE'S CONTROL OF ITS OWN SYSTEM <br /> 8.1.1 Naturally occurring microbes that will improve the quality of any <br /> contaminated groundwater or sewage treatment system are further <br /> t . enhanced by a reasonable and simple control system. <br /> 8.1.2 The microbes and nutrients applied to the contamination can only <br /> iw thrive with a carbon er.d nutrient source, in a range of temperature and <br /> PH that assures controllability. <br /> 8.1.3 Microbes will attack the HLOiter endP of any contaminant molecules <br /> first, thereby minimizing the possibility of air polhAtion. <br /> 8.1.4 Once the microbes find their food sources exhausted, they either <br /> die or are overcome bylocal soil °lora. <br /> 8.1.5 Ozone, is used in vapor control and extracted groundwater phases <br /> of this process, and for well flushing when needed, will destroy bacteria <br /> immediately and strip any residual volatiles left in the system. <br /> 8.2 MECM4NICAL AND IiYI)ItAULIC CONTROLS - INOCULUM INSERTION <br /> 8.2.1 This system is designed to assure optimum growing conditions in <br /> the zone of contamination without expanding the plume and treating <br /> volatiles before release to the atmosphere. <br /> The key is the kinetics of the vapor extraction Pystem, coupled with <br /> introduced organisms moving by force of capillary action and negative <br /> -- pressure drawing from each venting biowell. <br /> 11 HOLT805 <br />
