Frey Manager Director, Solid Waste Disposal District, Indian River County 1325 74th Avenue Southwest Vero Beach, Florida 32968 Subject: Proposal to Install and Monitor Upgradient Plume Monitoring Wells at the South Gifford Road Landfill and Prepare Biennial Reports for Four Closed Landfills in Indian River County Dear Mr. Frey: GeoSyntec Consultants (GeoSyntec) has prepared this proposal to address two separate work scopes required by Indian River County by the Florida Department of Environmental Protection (FDEP) . These scopes are : (i) expand the plume monitoring network upgradient of the landfill to monitor the movement and degradation of the plume north of South Gifford Road Landfill ; and (ii) prepare biennial reports for the Wabasso , Oslo , South Winter Beach, and Roseland Landfills . GeoSyntec submitted a work plan to FDEP on 6 February 2003 in response to the FDEP ' s 6 January 2003 letter that requested confirmation of the direct push investigation results to address the area of contaminated groundwater north of the South Gifford Road Landfill . We have developed a task-based approach to accomplish this work in an organized and cost-effective manner. The remainder of this letter provides a description of the proposed scope of work, a discussion of the schedule, and a budget estimate to accomplish the work described herein. PROPOSED SCOPE OF WORK Overview of Off-Site Assessment GeoSyntec conducted an off-site assessment in August- September 2001 to supplement the information obtained during the source assessment performed at the site in 2000 . The results were presented in the Technical Memorandum Presenting the Off-Site Assessment Results submitted to FDEP in January 2002 . The objectives of the off-site assessment field activities at the site were to delineate the horizontal and vertical extent of the dissolved volatile organic compound (VOC) plume upgradient and downgradient of the VOC source area at the South Gifford Road Landfill . Following delineation of the plume downgradient of the landfill, the existing monitoring well system was modified to monitor movement and XR03035/R030082 .DOC `� RECYCLED AND RECYCLABLE GEOSYNTEC CONSULTANTS Mr. Michael L. Frey 9 April 2003 Page 2 degradation of the plume ; however, no wells have been constructed upgradient of the VOC source area to monitor movement and degradation of the plume in this area. The off.-site assessment results indicated that the VOC plume is present upgradient of the source area for at least 500 ft. The presence of the VOCs upgradient of the source area may be attributed to several factors , including : (i) the influence of surface-water bodies that may affect local groundwater flow in the Surficial Aquifer, (ii) private wells located upgradient of the site (which may or may not be operating currently) , and (iii) diffusion. In response to the results of the off-site assessment conducted north of the South Gifford Road Landfill, FDEP has requested expansion of the plume monitoring network to address the areas of elevated dissolved VOC concentrations upgradient of the site. Installation and Monitoring of Upgradient Plume Monitoring Wells GeoSyntec has prepared a budget estimate in accordance with the Professional Services Agreement between GeoSyntec and Indian River County SWDD , Contract Number 9902 , to : (i) install and develop fifteen upgradient wells (five well clusters, each comprised of three monitoring wells) required for monitoring of the off-site plume; (ii) sample new groundwater monitoring wells ; (iii) collect soil samples of the silty, organic- rich layer that has been identified at the site; and (iv) prepare a report for submittal to FDEP documenting the fieldwork and sampling results . The scope of work has been divided into tasks to facilitate project management and efficient completion of the work. The tasks are summarized below. Task 1. Upgradient Off=Site Plume MonitoriaQ Task 1.1. Project Management Under Task 1 . 1 , GeoSyntec will perform project management responsibilities, such as correspondence, subcontracting, invoice reviews, project coordination, and project administration. The project management task is based upon supporting the anticipated scope of work defined herein. XR03035/R030082 .DOC mow, aecvcLEo nrvo nEcvcua� � r GEOSYNTEC CONSULTANTS Mr. Michael L. Frey 9 April 2003 Page 3 Task 1.2. Well Installation and Development Under Task 1 . 2 , GeoSyntec will install and develop the monitoring wells listed in Table 1 to confirm previous direct push investigation results in the area north of the South Gifford Road Landfill (north and northwest of the VOC source area) that suggest the presence of VOCs . The well installation and development will be conducted in accordance with FDEP Standard Operating Procedures (SOPS) that were promulgated in April 2002 . This task will involve the installation of fifteen ( 15 ) new monitoring wells, including five new well clusters of three monitoring wells each, to expand the plume monitoring network. The proposed locations for the plume monitoring wells are shown on Figure 1 . The new monitoring wells will be developed by surging and overpumping . Protective barriers (i . e. , bollards) will be installed around each new monitoring well or well cluster that may be subject to damage by heavy equipment or traffic . After installation, each new monitoring well will be surveyed by a Florida registered surveyor. The labor total includes two days ( 16 hrs) to prepare for the fieldwork, including scheduling, contract initiation and work order preparation with the subcontractors , equipment orders, and any other necessary fieldwork preparation tasks . The budget estimate for the fieldwork portion of this task assumes one person in the field for 10 hour days . The labor included in the budget estimate also assumes that the fieldwork will require approximately 12 to 13 days ( 120 to 130 hrs) for monitoring well installation and approximately three days (30 hrs) for well development . The budget estimate for this task also includes waste characterization; however, actual disposal of the waste will be handled by Indian River County as discussed below. With respect to investigation-derived waste (IDW) generated during GeoSyntec ' s fieldwork at the site, GeoSyntec will drum the drill cuttings and development water, stage the drums on-site, and mark each drum to indicate the source of the waste (e . g . , boring numbers, etc . ) contained within each drum, the generation date, and contact information. Waste characterization sampling and analysis will be performed consistent with IDW activities performed during previous contaminant assessment phases of work at the site. Two composite samples will be collected from the drums containing drill cuttings and one composite sample from the drums containing development water. These three samples XR03035/R030082 .DOC G� �, RECYCLED AND RECYCLABLE r GEOSYNTEC CONSULTANTS Mr. Michael L . Frey 9 April 2003 Page 4 will be submitted to a fixed-base laboratory for analysis by Toxicity Characteristic Leaching Procedure (TCLP) for Resource Conservation and Recovery Act (RCRA) metals, volatile compounds (EPA Method 8260), and semi-volatile compounds (EPA Method 8270) . The results of the analyses will be used to assess whether or not the IDW is characteristically hazardous and to evaluate appropriate disposal options . These drums will be marked as indicated earlier, placed on wood pallets, and stored at an on-site location designated by the SWDD . Any transport and disposal of wastes from the site will be arranged by the SWDD . Task 1.3. Groundwater Sampling Under Task 1 . 3 , GeoSyntec will perform groundwater level monitoring and groundwater sampling activities for the new plume monitoring wells listed in Table 1 . GeoSyntec proposes that the fifteen new monitoring wells be sampled after installation and development during the second semi-annual plume monitoring sampling event. The groundwater sampling activities will be performed in accordance with FDEP ' s SOPS . Groundwater levels in the new monitoring wells will be measured to the nearest 0 . 01 ft in conjunction with water level measurements of the entire plume monitoring network. During purging activities, groundwater will be monitored in the field for the following water quality parameters : temperature, pH, specific conductance, dissolved oxygen, turbidity, and oxidation reduction potential (ORP) . The proposed sample analyses are consistent with the existing plume monitoring network sampling. Groundwater samples will be collected from the fifteen monitoring wells and sent to an FDEP-approved laboratory for analysis for volatile organic compounds by EPA Method 8021 . GeoSyntec assumes that the laboratory analyses will be performed by Test America, who contracts directly with Indian River County. Therefore, we have not included analytical costs in this budget . The labor total includes one day (8 hrs) to prepare for the fieldwork, including scheduling, organization, equipment orders , coordinating with TestAmerica regarding the laboratory sample kits and analysis, and any other necessary fieldwork preparation tasks . The budget estimate for the fieldwork portion of this task assumes two people in the field XR03035/R030082 .DOC 40 RECYCLED AND RECYCLABLE r GEOSYNTEC CONSULTANTS Mr. Michael L. Frey 9 April 2003 Page 5 for 10 hour days . The labor included in the budget estimate assumes that the groundwater sampling fieldwork will require approximately four days (40 hrs) for monitoring well sampling (four wells per day) . Also included under this task is two days ( 16 hrs) for database management and data evaluation. Waste characterization will also be necessary under this task; however, the budget estimate for this task does not include the cost for waste characterization analyses . GeoSyntec assumes that Indian River County will contract directly with Test America for this laboratory analysis . Disposal will be handled by Indian River County as discussed below. With respect to IDW generated during GeoSyntec ' s groundwater sampling fieldwork at the site, GeoSyntec will drum the purge water, stage the drums on-site, and mark each drum to indicate the source of the waste (e . g. , monitoring well numbers , etc . ) contained within each drum, the generation date, and contact information . These drums will be sampled with the drums generated during the second semi-annual plume monitoring sampling event for the plume monitoring network at the site . The results of the analyses will be used to assess whether or not the IDW is characteristically hazardous and to evaluate the feasibility of discharging the purge water to the on-site treatment system. These drums will be marked as indicated earlier, placed on wood pallets, and stored at an on-site location designated by the SWDD . If the IDW characterization supports disposal of the liquid IDW through the on-site treatment system, it may be possible to discontinue characterization sampling after one to two sampling events . Any required transport and disposal of wastes from the site would be arranged by the SWDD . Task 1. 4. Soil Sampling Under Task 1 .4, GeoSyntec proposes to conduct one day of soil sampling to evaluate if source material is bound in the organic-rich, silty layer that has been identified in many borings at the site between 5 ft to 20 ft BLS (thickness of this layer is generally 2 ft to 6 ft) . The budget estimate includes laboratory analysis of up to ten soil samples for EPA Method 8021 and analysis of up to six soil samples for fraction organic carbon (foc) by the Walkley Black method . This information will be critical in evaluating the appropriateness of source removal activities for the Remedial Action Plan (RAP) to be submitted to FDEP during summer 2003 . XR03035/R030082 .DOC r, RECYCLED AND RECYCLABLE � r GEOSYNTEC CONSULTANTS Mr. Michael L. Frey 9 April 2003 Page 6 The budget estimate for this fieldwork task assumes one person in the field for one 12- hour day to complete the soil sampling. Task 1.5. Reporting The results of the expanded off-site assessment will be summarized in a letter report that will include well construction details , applicable field notes and observations, lithologic logs, groundwater sampling logs, maps, and analytical results . The analytical results will also be used in preparing the RAP . Preparation of Biennial Reports Task 2. Biennial Reporting — Closed Landfill Sites GeoSyntec will prepare Monitoring Plan Implementation Schedule (MPIS) biennial technical reports for the Wabasso , Oslo, South Winter Beach, and Roseland Landfills (total of four individual reports) . The technical reports will summarize and interpret the water quality data and water level measurements collected by Indian River County and/or Test America Laboratory for the past four sampling events . The technical reports for each of the four sites will contain, at a minimum, the following : • tabular and graphical displays of any data which shows that a monitoring parameter has been detected, including hydrographs for all monitoring wells ; • trend analyses of any monitoring parameters detected; • comparisons among shallow, middle, and deep zone wells ; • comparison between upgradient and downgradient wells ; • correlation between related field parameters such as total dissolved solids and specific conductance; • discussion of erratic and/or poorly correlated data; • an interpretation of the groundwater contour maps , including an evaluation of groundwater flow rates ; XR03035/R030082 .DOC G. RECYCLED AND RECYCLABLE � r GaoSyNpmc CoNSmrmm Mr. Michael L. Frey 9 April 2003 Page 7 • an evaluation of the adequacy of the water quality monitoring frequency and sampling locations based upon site conditions ; and • recommendations regarding cessation of sampling or reduction in sampling (wells or parameters) recommended for each site, based oil site-specific data. The biennial technical reports will be submitted to Indian River County for review prior to submittal to the FDEP . The Final reports for cacti of the four sites will he siumcd and sealed by the designated professional engineer and/or geologist in responsible charoc of the project.
