Pmferz ed Alternatives <br /> The results of the preliminary engineering evaluation identified <br /> preferred alternatives for the remediation of both hydrocarbon- <br /> containing soils and ground water at the site. For site soils, the two <br /> preferred alternatives are on-site aeration and biotreatment. For <br /> biotreatment, the options include both landfarming and composting <br /> J.-.ch X.-19. Based on information currently available, the X-19 option <br /> is the most cost-effective alternative. <br /> For ground water, the preferred alternatives are ground water <br /> extraction and treatment (via air strippers or activated carbon), <br /> biotreatment, and chemical oxidation. The biotreatment and <br /> chemical oxidation alternatives include both in situ and ex situ <br /> options. <br /> As mentioned previously, the 1325 West Weber site has not been fully <br /> characterized. Due to limited field information, these remedial <br /> alternatives for the site will be more closely evaluated after field <br /> studies are completed at 1325 West Weber. The final remedial <br /> alternatives for both soil and ground water will then be determined. <br /> 6-9 <br />
