increase the upper limit of this Amendment by the remaining amount exceeding the <br />estimated costs as provided herein. <br /> <br />Subtask 2.3 - Geotechnical Laboratotw Testing <br /> <br />During drilling operations, undistributed (Shelby Tubes) soil samples will be collected at <br />each well location for laboratory testing of soil porosity for the formation materials within <br />the surficial aquifer at the screen interval as required by Section .1632 (d) of the SWS <br />rules. A total of seven soil samples will be submitted for laboratory analysis. Soil <br />samples will not be collected from the gas monitoring well borings. <br /> <br />Subtask 2.4 - Well Completion Records and Boring Logs <br /> <br />CDM will complete well completion records and boring logs for each groundwater <br />monitoring well and gas well. A copy of the well completion records and boring logs will <br />be included in the final report referenced in Task 6. <br /> <br />Subtask 2.5 - Hydraulic Conductivity (Slug) Tests <br /> <br />Rule .1632 (d) requires that the rate and direction of groundwater flow be determined. <br />CDM will conduct a rising or failing head hydraulic conductivity test at each of the new <br />groundwater monitoring wells to determine groundwater flow velocities and <br />characteristics. <br /> <br />TASK 3 - MONITOR WELL LOCATION/ELEVATION SURVEYING & <br />BENCHkL,~RKS <br /> <br />The North Carolina SWS requires that all monitoring wells be surveyed. CDM will retain <br />a North Carolina Registered Land Surveyor to provide horizontal and vertical control for <br />each well as required. Survey data will be tied to the required on-site benchmarks. <br />Horizontal control is required to the nearest 0.1 foot while vertical control to the nearest <br />0.01 foot and in NCSP coordinates. <br /> <br />TASK 4 - MONITOR WELL AND SURFACE WATER SAMPLING AND <br />ANALYSIS <br /> <br />.As part of the transition plan, the SWS required the collection of four independent <br />samples from each of the monitoring wells located around the existing landfill prior to <br />October 9, 1994. The SWS recently revised its policy and now requires that one sample <br />be collected before October 9, 1994 and the remaining three samples be collected before <br />April 9, 1995. These samples will be collected in lieu of the normal semi-annual <br />sampling. Under this task, CDM will collect the four independent samples from each of <br />the seven new monitor wells and the two existing monitor wells (incorporated as per the <br />letter from the SWS). In addition, during two of the sampling events, samples will be <br /> <br /> <br />
