NOV 1 3 1990 <br /> Director of Environment and Engineering EtMRONMENT <br /> City of San Marcos <br /> 630 E. Hopkins a ENGINEERING <br /> San Marcos, Texas 78666 <br /> RE: Work Plan and Cost Estimate for Ground-Water Sampling and Analysis, City of San <br /> Marcos Landtlll, Gary Job Corps Center, Caldwell County, Texas <br /> Dear Mr. Jenkins: <br /> McCulley, Frick and Gilman, Inc. is pleased to provide this Work Plan and Cost Estimate to <br /> continue ground-water monitoring activities for the City of San Marcos landfill at the Gary Job <br /> Corps Center under the terms and conditions of the contract dated 2/27/90. The scope of <br /> work and estimated costs to conduct quarterly ground-water sampling and analysis for the six <br /> existing monitoring wells are provided. OUf estimate assumes that samples will be collected <br /> from only four of the six wells each quarter, based on historical evidence that wells MW-I01 <br /> and MW-1O6 are dry. Please note that in their October 22, 1990 letter, the TDH has also <br /> requested semi-volatile organics, which increases the analytical costs from $ 619.92 to $ 997.92 <br /> per ground-water sample. <br /> In addition to sampling, analytical and reporting charges for the four quarterly monitoring <br /> events, other costs are listed, including the costs of two more laboratory analyses (a total of <br /> eight analyses instead of the the six proposed for the April and August 1990 sampling events), <br /> measuring monitoring well water levels on November 9, 1990 and again the following week, <br /> and some time for coordination/communication with the City and mH. <br /> We appreciate the opportunity to work with the City of San Marcos. Please feel free to call <br /> me if you have any questions regarding the Work Plan or Cost Estimate. <br /> Sincerely, <br /> McCULLEY, FRICK & GILMAN, INC. <br /> ~~ /.r~ <br /> Douglas R.
