O . Plant , Facility #9600729 Vero Beach, FL 32962 Dear Mr. Southard, Geosyntec Consultants (Geosyntec) is pleased to submit this fee proposal to Indian River County (IRC) for professional services required to provide reporting documentation to respond to Florida Department of Environmental Protection' s (FDEP ' s) correspondence dated 23 May 2011 . The FDEP correspondence was generated based upon a review of Geosyntec ' s 28 October 2010 report, October 2010 Natural Attenuation Monitoring Report, North RO Plant, Facility #9600729. Based upon FDEP ' s correspondence, two additional sampling events are warranted in order to confirm plume stability. The following conditions apply to the FDEP request : • The wells and piezometers to be sampled are MW03 , MW05, MW06, MW07, PZI S, PZ17, PZ21 , PZ22, PZ23, PZ24 and PZ26. • Two groundwater sampling events will be completed. The parameters of analysis shall be total dissolved solids, chloride, sodium and sulfate for groundwater samples . The field measurements during purging shall be temperature, pH, specific conductance, turbidity and dissolved oxygen . Purging and sampling methods in the Department 's Standard Operating Procedures shall be followed. • Reports for each groundwater monitoring event shall include a cumulative summary table of all groundwater monitoring results including from assessment phases. The parameters reported in the table shall be pH, turbidity, total dissolved solids, chloride, sulfate and sodium. Reports shall contain a map depicting the direction of groundwater XR 1 1179/CCR 1 1065 , 130C engineers I scientists I innovators Mr. Terry Southard Geosyntec ® 29 July 2011 consultants Page 2 flow and maps depicting plumes. Reports shall contain copies of field sampling logs and laboratory reports • An additional report will be provided to respond to the FDEP comments from the 23 May 2011 correspondence. The proposed scope of work summarized below is intended to only provide reporting documentation regarding the implementation of the semi - annual groundwater sampling events for a duration of one year at the Site and respond to FDEP comments in a cost effective manner . Please note that IRC has indicated that they will subcontract the sampling activities and provide Geosyntec with documentation from the sampling efforts that will be compliant with all applicable FDEP guidance and standard operating procedures ( SOPS) . PROPOSED SCOPE OF WORK Task 1 — Response to FDEP Comments Geosyntec will provide a Letter Report responding to the comments and options recommended by . the FDEP in the 23 May 2011 correspondence for possible site closure requirements . Task 2 and Task 3 — Groundwater Sampling Report Preparation (2 Submittals) For each event, upon receipt from IRC of the final data package of the field activities and the laboratory results of the groundwater sampling effort , Geosyntec will evaluate the data and incorporate these findings into a report for submission to FDEP within approximately 60 days from the date of sample collection . If we find during completion of this task that additional sampling and/or reporting work is necessary, we will discuss our recommendations with you and seek approval prior to proceeding. For each of the two proposed groundwater sampling events , Geosyntec ' s findings obtained through the evaluation of the sampling documentation provided by IRC will be presented in a report for submission to FDEP . Please note that Geosyntec has included budget in this tusk for the review and evaluation of data packages by [RC 's subcontractor of the field activities and the laboratory results of the groundwater sampling effort. These two reports will provide details of the work performed by IRC ' s sampling subcontractor including sample locations , sampling methodology, analytical results and groundwater elevations . A draft report will be provided to you for review 'and comment before the final version is submitted to FDEP . Geosyntec will XR I 1179/CC R 1 1065 . DOC engineers I scientists I innovators Mr. Terry Southard Geosyntec "' 29 July 2011 consultants Page 3 submit one hard copy and one electronic copy of each final groundwater sampling report to the FDEP and one hard copy and a PDF on CD will be provided to you. ASSUMPTIONS In addition to the above, the following assumptions were made in developing this scope and cost estimate : • IRC and/or IRC ' s sampling subcontractor will notify FDEP of the date of each of the proposed semi - annual sampling events at least 3 days in advance of sampling. • In advance of purging/sampling of any wells during a sampling event, IRC will have their subcontractor conduct the required depth to groundwater measurements from the monitoring wells required by the FDEP - approved NAM plan. Water-level measurements will be used by Geosyntec in conjunction with the existing surveyed well elevations for continued evaluation of groundwater flow directions . • Issues identified by Geosyntec associated with the data package provided by IRC of the field activities and the laboratory results of the groundwater sampling effort will be addressed by IRC at no cost or effort to Geosyntec . • Budget has not been included for any additional delineation sampling or monitoring well installations . ESTIMATED BUDGET The proposed scope of work will be completed on a time and materials basis . The cost for performing the preparation of a response to comments letter report and two semi - annual groundwater sampling reports is $7, 179 . Any requested tasks which are outside the defined scope of work will be completed in accordance with the hourly rate schedule negotiated with Indian River County ( SWDD Contract) . A summary of estimated project costs is included in Attachment A . CLOSURE Geosyntec appreciates the opportunity to submit this proposal to provide environmental consulting services to the IRC Utilities Department . Upon receipt of the Purchase Order from XR I 1179/CCR 11065 . DOC engineers I scientists I innovators Mr. Terry Southard GeosynteC ® 29 July 2011 consultants Page 4 IRC , Geosyntec will immediately begin preparation of a response to FDEP ' s correspondence dated 23 May 2011 .
