One boring will be advanced below the distribution <br /> box to a depth of 4 feet. One boring will be advanced below the septic tank to a total depth of <br /> 12 feet. The final boring will be advanced through arse of the seepage pits to a total depth of 27 <br /> feet. Keep in mind that EHD may require that samples be collected at each of the seepage pits, <br /> however, post o y sampling one, <br /> Soil samples will be collected at 3-foot intervals(in the deeper borinp) for soil classification <br /> and possible anwalysis. A soil sample will also be collected from the bottom of each boring. <br /> a Subzmit the samples to appropriate laboratories for the analyses required by EHD in their letter <br /> and prepare a report ging the tesults. <br /> The ost mated coat for the proposed scope of work is S 3,227.!10. Exhibit A, amohed, provides <br /> more detail on the estimated costs associated A ith the workscope. <br /> If you wish us to proceed with the wodc aid if this coat estimate is acceptable please sign in the <br />
