Mr. Himanshu H. Mehta, P.E. 8 May 2015 Page 4 I F1Jl eURY E F!CATIONON«STPAGE SMITH. CLERK Geosyntec t> consultants in December) and will include sampling of 28 monitoring wells (25 wells using PDBs and 3 wells with traditional sampling techniques). The semi-annual field event is budgeted to include two days for groundwater sampling activities and one day for PDB deployment for the next sampling event (total of three days). Consistent field documentation and field protocols will be utilized to develop reliable data to support the natural attenuation of the groundwater plume. The groundwater samples will be analyzed in accordance with the sampling plan summarized in the December 2014 Semi -Annual Groundwater Monitoring Report. Geosyntec will conduct a complete round of groundwater level measurements coincident with each semi-annual groundwater sampling event (budgeted for one day with two -person field team for each event). Depth to groundwater measurements will be recorded to the nearest 0.01 -ft in each monitoring well, including existing monitoring wells and applicable City of Vero Beach wells (assumed up to 88 wells per event). It is anticipated that purge water (investigation -derived waste [IDW]) will be containerized in 55 -gallon polyethylene drums and temporarily staged on Site for characterization prior to removal and disposal. Costs are included herein for two 55 -gallon polyethylene drums and two transport trips. Overall, budget has been included for ten field days with a two -person team (i.e., 20 man days) and associated field expenses for sampling, plus two days for IDW management. Task 5 — Data Evaluation and Semi -Annual Reporting: Under this task, Geosyntec will perform data evaluation activities and reporting. The reporting includes preparation of one semi- annual report (simplified format) and one annual report for submittal to FDEP. The annual report will be consistent with the groundwater monitoring reports historically submitted to FDEP for this Site and the data evaluation activities will include database management, screening results against applicable regulatory criteria, GIS figure preparation, time trend analyses, and/or statistical data analyses. This report will be prepared following the June groundwater sampling event. The annual report will be supported by attachments containing Chain -of -Custody sheets, field notes and observations, water sampling logs, maps, graphs, analytical results, and any other applicable materials. The semi-annual report will be a letter report with attachments, including a monitoring well location map and tables of the field and laboratory results. Data evaluation activities for the semi-annual report will include database management, screening results against applicable regulatory criteria, and summary data table preparation. This report will be prepared following the December groundwater sampling event. XR15143\XR15021 engineers 1 scientists 1 innovators
