2013-27 0 TETRA TECH May 3, 2013 Mr. James Kinzler, CPM, EA Director of Environmental Services City of Clermont 3335 Hancock Road Clermont, FL 34711 Subject: Proposal for Professional Services City of Clermont—Eastside WWTF Installation and Sampling of Two FDEP Monitoring Wells Tt# 2O0BP Clermont/FDEP Monitoring Wells Dear Mr. Kinzler: This letter outlines a scope of services for tasks related to compliance with the Florida Department of Environmental Protection (FDEP) Ground Water Requirements,of Domestic Wastewater'Facility Permit No. FLA010515-010, dated December 28, 2012. Tasks proposed herein include: • review of site conditions and nearby monitor wells for preliminary design, • discussion and confirmation of preliminary well design by the FDEP Central District, • preparation of documents to procure bids from three licensed well drilling contractors, • review of bids and recommendation of award, • installation of one (1) background and one (1) compliance monitoring well, • sampling of the wells for the analytes required by the FDEP, • surveying the top-of-casing elevation and location of each new monitoring well, and • completion of documentation well construction and sampling results. In preparing this proposal, we reviewed the terms of the Domestic Wastewater Facility Permit and the approved locations of the background and compliance wells provided by the City, and relied on other relevant information concerning the Eastside reclaimed water system and local topographic and geologic data. We understand that time is of the essence and will provide you with a project schedule, including estimates on the dates of drilling, sampling, and receipt of laboratory results as quickly as possible after receipt of approval to begin work. We estimate that monitoring well installation, development, testing, and sampling will require approximately two to three weeks Tetra Tech, Inc. 201 E Pine Street,Suite 1000,Orlando, FL 32801 Tel 407 839 3955 Fax 407 839 3790 www tetratech corn ElTETRA TECH Mr. James Kinzler May 3,2013 Page 2 following approval of the proposed scope of work. Laboratory analyses of groundwater samples from the new wells will require approximately one to two weeks. We will submit a well installation and sampling report to the City within two weeks of receipt of laboratory water quality results. The proposed scope of services for this project is outlined below, and we propose to provide a recommended drilling contractor within one week from NTP, and to complete "all" tasks within 45 days from the notice to proceed. The proposed compensation for the Scope of Services described herein will be billed on a time and material basis with an initial upset limit of$4,903,based on the attached compensation summary. SCOPE OF SERVICES Task 1 —Preliminary Well Design/Bidding Services Tetra Tech will complete tasks necessary to prepare documents to solicit bids from three (3) licensed well,drilling contractors. Specific tasks include review of topographic maps, soils, and water levels at the proposed site and review of monitor well designs from nearby sites for comparison. We will prepare preliminary monitoring well designs suitable for the new proposed well locations, such that line item quotes can be provided by Florida licensed well drilling contractors. Following receipt of the three bids for the proposed monitor well installation, we will review each bid and make a recommendation of award to the City. Task 2—Monitoring Well Installation, and Sampling Task 2 includes field oversight of installation of new monitoring wells and sampling of the two new monitoring wells. Tetra Tech assumes the City will contract directly with the recommended drilling contractor. The the,driller will collect lithologic samples using either standard penetration test (SPT) or direct-push technology (DPT) borings. From these samples, a Tetra Tech professional geologist will review lithologic samples at each well site to determine the most suitable well designs. Each monitoring well will be installed in accordance with FDEP requirements and will be documented on FDEP well completion report forms. The driller will provide a well completion report on Water Management District forms. The driller will engage the services of a Florida licensed surveyor to survey the location, top-of-casing elevation, and land surface elevation. Those data will be included on the FEP well completion report forms. Each new well will be developed until free from sand and silt and until turbidity is less than 20 NTU. Following a wait of at least 48 hours, each well will be purged and sampled for the analytes required by Section III.B.5 of FDEP DWF permit No. FLA010515- 010. L Ezi TETRA TECH Mr. James Kinzler May 3, 2013 Page 2 Task 3 —MW Installation Documentation The results of well installation, testing, and groundwater sampling, will be documented on FDEP monitoring well installation report forms and Water Management District well completion report forms that are required for submittal by the FDEP No. FLA010515-010. The well completion report will also include the results of groundwater sampling obtained from the City's laboratory contractor. ESTIMATED COSTS: Task Fee Task 1 Prelimin. Design $1,400.00 Task 2 Well installation, sampling, analyses, surveying $2,803.00 Task 3 Summary resort $700.00 TOTAL (Task 1 - 3) $4,903.00 The estimated cost and man-hours are provided in the attached price summary table for your review. Our quote assumes that lab fees will be directly invoiced to the City and that the City will engage the driller and surveyor. We appreciate the opportunity to continue to provide our services to Toho, and look forward to working with you on this project.
