This additional sampling and analysis <br /> is not part of this proposal and is not included in our cost of ser- <br /> vices. <br /> TASK 6 - Surveying and Preparation of Aerial Topographic Map <br /> Ground surface elevations will be surveyed for all exploratory borings <br /> and wells, and top of casing elevations will be surveyed for the three <br /> monitoring wells and two permeameters. This elevation data will be used <br /> to locate the borings and to calculate hydraulic gradient of the water <br /> table below the site. The cost of this service is based on the assump- <br /> tion that an appropriate bench mark is located in the vicinity. <br /> After the site has been properly surveyed for control, it will be flown <br /> and photographed. Using photogrametric methods, a topographic map of <br /> the site will be prepared from the aerial photographs at a mapping scale <br /> of 1 inch = 100 feet with 2 foot contour interval. <br /> TASK 7 - Geologic Description , <br /> The geology of the proposed landfill site and adjacent property will be <br /> described based on the exploration program proposed here and the review <br /> PRA 8610-22E 11-6 <br /> Emcon Associates . <br />
