The GAC filter is both an adsorber, and a high surface area for <br /> completion of the ADVOX procedure. <br /> N/A = No test sample drawn <br /> 6 The GAC phase of treatment is believed to combine the large carbon surface <br /> area to finish the ADVOX cycle, augmenting its standard adsorption role. <br /> Ozonated fluids will prevent micro-organisms from fouling the GAC to give it <br /> longer usable life. <br /> 7 Worst case Petroleum Hydrocarbons from Table 1 of Soil borings reports, <br /> Dames and Moore Report of November, 1989. (B-05 at 20.0 feet) <br /> No Significant Chlorinated hydrocarbons detected in soils per above report. <br /> Methylene Chloride (350 ppb) was found at 16' on 4/27/88. <br /> HOLT103 <br /> 6 <br />
