Union Ice Company ... August 6, 1993 <br /> Soil Remediation Work Plan at 1320 Weber Street page 2 <br /> areas where a ND amount of kerosene is reflected. All of the overburden material <br /> is included with the stockpiled soils. Considering these procedures and a <br /> maximum level of detection of 1,100 ppm, an average level of contaminant is <br /> assumed to be less than 300 ppm. <br /> The graded soils will be moistened to accept the application of a bacteria culture. <br /> The bacteria culture is bred with the specific purpose of using the hydrocarbons as <br /> a "food of choice". The culture will be applied at a rate of about one pound per <br /> one-hundred (100) cubic yards of soil. <br /> This soil/culture mix will be stirred at the total depth approximately every other <br /> day for a period of twelve (12) weeks. Water will be applied to enhance the <br /> degradation process and to minimize the dust nuisance to the surrounding <br /> properties. A sprinkling system will be installed, possibly with timers, to ensure <br /> that the bacteria process will continue. <br /> Table 1 Soil Results <br /> Kerosene- (mg/kg) <br /> Location Depth Date Results <br /> -- Bottom 37' 4/23/93 1,100 <br /> South Wall 20' 4/27/93 158 <br /> West Wall 15' 4/27/93 138 <br /> East Wall 20' 4/27/93 96 <br /> North Wall 19' 4/27/93 116 <br /> -� 2.2 Soil Sampling Methodology <br /> The entire area of treatment will be divided into a gridwork containing <br /> approximately fifty (50) cubic yards (Figure 3). Twenty-four (24) discrete <br /> samples, one from each fifty (50) cubic yard area, will be taken at the end of the <br /> twelve week treatment cycle. <br />
