Soil will be <br /> examined during excavation for subjective evidence of <br /> contamination including odor and visible discoloration, and using <br /> an Organic Vapor Analv�er (OVA) , Hydrocarbon contamination in <br /> Cie tank cavity will be excavated until no subjective. evidence of Wl,4 <br /> contamination remains if <br /> Possible. If the volrme of removed �� <br /> soil becomes excessive, soil contamination appears to extend <br /> beneath the building, or tha depth of the excavation exceeds the <br /> s� <br /> safe operating limits of the equipment, the excavation will be: <br /> terminated and further procedures for remediation will be <br /> evaluated. <br /> 6 <br /> A,opiied GeoSystems --- <br />
