Plant, Facility #9600729 Vero Beach, FL 32962 Dear Mr. Southard, 6770 South Washington Avenue, Suite 3 Titusville, Florida 32780 PH 321.269.5880 FAX 321.269.5813 w% W.geosyntec.com 31 March 2008 Geosyntec Consultants (Geosyntec) is pleased to submit this fee proposal to Indian River County (IRC) for professional services required to respond to Florida Department of Environmental Protection's (FDEP's) correspondence dated 19 February 2008. The FDEP comments were generated based upon a review of Geosyntec's 21 December 2007 letter report, Initial Assessment of Suspected Caustic Release, North RO Plant, Facility 49600729. Based upon FDEP's review of the letter report, the following additional tasks have been requested: • A determination of the site groundwater flow direction; • installation of piezeometers in the eastern area of pH impacted groundwater to provide complete lateral delineation; • installation of a monitoring well to provide vertical delineation of groundwater pH impacts; • collection and laboratory analyses of groundwater samples for sodium; and • the provision of a map to the FDEP with a proposed location for a site background monitoring well (to be installed upon FDEP approval at a later date). FRI329,CCR08028.D0C engineers I scientists I innovators Mr. Terry Southard 31 March 2008 Page 2 The proposed scope of work summarized below is intended to respond to the FDEP comments in a cost effective manner. PROPOSED SCOPE OF WORK • Mobilize to the site (professional and site/field manager) and east of the existing monitoring well (MW01) install up to five, '/-inch diameter piezometers to a depth of 8 to 10 ft below land surface (BLS - depth to groundwater estimated at approximately 5 ft BLS) using hand auger equipment to supplement the previously installed piezometers and provide lateral delineation of the pH impacted groundwater. Geosyntee assumes that IRC site personnel will provide support in regards to the identification of potential underground utilities and clearing proposed piezometer locations (the area the FDEP has requested additional piezometers is in the close vicinity of site structures). • Provide oversight of the installation of one permanent deep -screened monitoring well (approximate depth of 30 -ft BLS), to provide vertical delineation of pH impacted groundwater in the vicinity of the area of highest observed pH impacts using direct push technology (DPT) drilling techniques. Note: Geosyntec will collect a groundwater sample from the interval from 25 -ft to 30 -ft BLS via DPT and field screen to verify pH is below 8.5 prior to well installation. If the pH at a depth of 25 to 30 ft BLS exceeds 8.5, the monitoring well will be installed to a maximum depth of 40 ft BLS. • Collect a complete set of groundwater level measurements and performing groundwater sampling activities in accordance with FDEP Standard Operating Procedures. Groundwater samples from up to 13 piezometers and two monitoring wells will be collected and laboratory analyzed for sodium by EPA Method 6010 and field screened for pH. • Perform an elevation survey of the monitoring wells and all piezometer top -of -casing elevations. The top -of -casing elevations will be referenced to a common datum or a benchmark elevation at the plant provided by IRC. The survey information will be used in conjunction with the groundwater level measurements to compute the groundwater elevation and site groundwater flow direction. • Evaluate the collected data and prepare figures which illustrate the piezometer locations, individual analytical results, and groundwater potentiometric surface. Prepare a draft letter report for IRC review which summarizes the results (tables and figures) and FR 1329./CCR08028.DOC engineers I scientists I innovators Mr. Terry Southard 31 March 2008 Page 3 includes recommendations for the site. As requested by the FDEP, the letter report will include a MSDS for sodium hydroxide and a proposed background well location with construction details (for FDEP's approval). The final letter report (up to five copies) will be signed/sealed by the Florida licensed Professional Engineer in responsible charge of the project. ASSUMPTIONS During the preparation of this proposal, Geosyntec has made the following assumptions: • Access to sampling locations is not restricted to Geosyntec. • All sampling can be performed in Level D personal protective equipment. • The field activities will be completed in two days. Please be advised that the installation of additional piezometers and/or a permanent monitoring well network may be required to fully delineate the pH impacts (laterally and vertically). • The letter report is intended to specifically comply with FDEP's 19 February 2008 letter and is not intended to meet the intent of a Chapter 62-780, Florida Administrative Code Site Assessment. • Geosyntec will be able to work unimpeded between Monday and Friday from 7 am - 7 pm. ESTIMATED BUDGET A summary of estimated project costs is included in Exhibit 2 attached. CLOSURE Geosyntec appreciates the opportunity to submit this proposal to provide environmental consulting services to the IRC Utilities Department. Upon execution of the Work Order, Geosyntec will immediately schedule the field activities. We anticipate that the field activities will be completed within three weeks of Work Order execution. The letter report summarizing the field activities will be completed within approximately two weeks of receipt of the laboratory analytical results. FR1329/CCR08028.
