Mr. Himanshu H. Mehta, P.E. Geosyntec <br /> 8 May 2015 consultants <br /> Page 4 <br /> in December) and will include sampling of 28 monitoring wells (25 wells using PDBs and 3 <br /> wells with traditional sampling techniques). The semi-annual field event is budgeted to include <br /> two days for groundwater sampling activities and one day for PDB deployment for the next <br /> sampling event (total of three days). Consistent field documentation and field protocols will be <br /> utilized to develop reliable data to support the natural attenuation of the groundwater plume. The <br /> groundwater samples will be analyzed in accordance with the sampling plan summarized in the <br /> December 2014 Semi-Annual Groundwater Monitoring Report. <br /> Geosyntec will conduct a complete round of groundwater level measurements coincident with <br /> each semi-annual groundwater sampling event (budgeted for one day with two-person field team <br /> for each event). Depth to groundwater measurements will be recorded to the nearest 0.01-ft in <br /> each monitoring well, including existing monitoring wells and applicable City of Vero Beach <br /> wells(assumed up to 88 wells per event). <br /> It is anticipated that purge water (investigation-derived waste [IDWJ) will be containerized in <br /> 55-gallon polyethylene drums and temporarily staged on Site for characterization prior to <br /> removal and disposal. Costs are included herein for two 55-gallon polyethylene drums and two <br /> transport trips. <br /> Overall, budget has been included for ten field days with a two-person team (i.e., 20 man days) <br /> and associated field expenses for sampling, plus two days for 1DW management. <br /> Task 5 — Data Evaluation and Semi-Annual Reporting: Under this task, Geosyntec will <br /> perform data evaluation activities and reporting. The reporting includes preparation of one semi- <br /> annual report(simplified format)and one annual report for submittal to FDEP. <br /> The annual report will be consistent with the groundwater monitoring reports historically <br /> submitted to FDEP for this Site and the data evaluation activities will include database <br /> management, screening results against applicable regulatory criteria, GIS figure preparation, <br /> time trend analyses, and/or statistical data analyses. This report will be prepared following the <br /> June groundwater sampling event. The annual report will be supported by attachments <br /> containing Chain-of-Custody sheets, field notes and observations, water sampling logs, maps, <br /> graphs, analytical results, and any other applicable materials. <br /> The semi-annual report will be a letter report with attachments, including a monitoring well <br /> location map and tables of the field and laboratory results. Data evaluation activities for the <br /> semi-annual report will include database management, screening results against applicable <br /> regulatory criteria, and summary data table preparation. This report will be prepared following <br /> the December groundwater sampling event. <br /> XR15143\XR15021 <br /> engineers I scientists I innovators <br /> 244 <br />
