Applied conducted tests on both the process water and the <br /> groundwater The objective in both applications was to reduce the MTBE to less than 5 ppb, <br /> Process Water <br /> When starting on this project, it was assumed based on previous analysis that the process <br /> water MTBE and BTEX Concentration would be approximately 250,000 ppb. Actual process <br /> water concentrations were significantly greater than the expected <br /> On 1118199 and 1119/99, the HiPQx Pilot system was operated as duplicates of each other. <br /> However, because of the significantly greater than expected concentration of contaminates <br /> insufficient ozone was added to achieve complete destruction. On 1/28199, the HiPOx pilot <br /> system was operated with sufficient ozone to achieve complete destruction of the MTBE <br /> The remediation test results are summarized in Figure 6. <br /> Influent Effluent Influent Effluent Influent Effluent <br /> 340,000 2,900 510,000 34,000 230,000 069 <br /> 10,200 <50 11,500 <130 <5000 <0.5 <br /> <25,000 42,000 <50,000 41,000 <100,000 <10 <br /> <25,000 45,000 <50,000 60,000 <100,000 650 <br /> Figure 6, Summary Results from Process <br /> Ground Water. <br /> The Ground Water MTBE concentration at the Fuel Terminal as expected was found to be <br /> approximately 10,000 ppb plus approximately 5,000 ppb BTEX.
