The proposal has been prepared in general accordance with the Professional Services Agreement (PSA) between GeoSyntec and IRC Solid Waste Disposal District ( SWDD), dated 10 August 2004 , XR05010 IRC MPIS-PM Sampling\R050001J-rev coRECYCLED AND RECYCLABLE r , EOSYNTEC CONSULTANTS Mr. Tanhum Goldshmid Indian River County, Solid Waste Disposal District 3 May 2005 Page 2 The remainder of this letter provides an overview of the MPIS required by FDEP, a discussion of the work associated with CVOC plume monitoring (including additional monitoring wells) , summary of the P&T system reporting requirements, description of the proposed scope of work, a discussion of the schedule, and a budget estimate to accomplish the work described herein . OVERVIEW OF MPIS As part of the long-term monitoring for the South Gifford Road Landfill , GeoSyntec, on behalf of IRC SWDD, has been implementing the FDEP -required MPIS since June 2002 . The MPIS is designed to monitor the groundwater so that releases to the oundwater from the landfill will be detected by the groundwater monitoring system. A biennial report was submitted to FDEP in August 2004 and the recommendations set rth in this document were subsequently approved in a letter from FDEP dated 7 January 2,005 . Based on the biennial report and FDEP approval, IRC is required to continue to collect and analyze groundwater samples from existing groundwater monitoring wells listed in Table 1 for the following : • CVOCs by EPA Method 8021 or 8260 ; • chloride by 300 . OA or E325 . 2 ; • total dissolved solids (TDS) by 160 . 1 ; • phenols by EPA Method 9065 ; and • total metal analyses for iron and lead by EPA Method 6010 . A modified MPIS , inclusive of the approved recommendations, was provided b FDEP and is included as Attachment A to this fee proposal . OVERVIEW OF CVOC PLUME MONITORING As part of the long-term monitoring activities associated with the identified CVOC plume located beneath, and extending from, the South Gifford Road Landfill , a network of monitoring wells will require sampling on a semi-annual basis to : XR05010 IRC MPIS-PM Sampling\R050000-rev.doc RECYCLED AND RECYCLABLE r r . l 'YEOSYNTEC CONSULTANTS Mr. Tanhum Goldshmid Indian River County, Solid Waste Disposal District 3 May 2005 Page 3 • confirm that the CVOC plume is not migrating by monitoring the lateral and vertical extent (which requires the installation of additional proposed monitoring wells since the CVOC plume is currently not delineated) ; • evaluate the impact of source remediation and P&T operations to assess C VOC plume centerline concentrations over time ; and • assess the impact of biological and physical natural attenuation processe 15 on CVOC plume degradation . OVERVIEW OF P&T SYSTEM REPORTING As part of the reporting requirements presented in the RAP , quarterly II&T system letter reports are required to document the following : • groundwater volumes processed by the air stripper during the reporting period ; • effectiveness of the air stripper in removing CVOCs ; • operation and maintenance (O&M) activities performed during the repor .ing period; and • any repairs or operational problems . Presently, all P&T system-related O&M activities and system sampling are performed by IRC personnel . It has been assumed for costing purposes herein that IRC ill continue to perform these activities . PROPOSED SCOPE OF WORK GeoSyntec developed a phased approach with internal task elements to accomplish this work in an organized and cost-effective manner. The remainder of this let er provides a description of the proposed scope of work and a budget estimate to accompli h the work described herein. XR05010 IRC MPIS-PM Sampling\R050001J-rev.doc e, RECYCLED AND RECYCLABLE � r i . EOSYNTEC CONSULTANTS Mr. Tanhum Goldshmid Indian River County, Solid Waste Disposal District 3 May 2005 Page 4 Task 1 — Proiect Manaument/Meetino Under this task, GeoSyntec will perform project planning and management responsibilities, such as correspondence with IRC and FDEP, invoice rev ew, project coordination, and project administration . GeoSyntec has also included budget for preparation and attendance (by two GeoSyntec personnel) at one meeting with IRC and/or FDEP, as needed. Task 2 — Field Activities Under this task, GeoSyntec will perform all field activities related to the MPIS and plume groundwater monitoring, as discussed herein . The field activities will include : (i) field preparation; (ii) well installation and development ; (iii) well redevelopment; and (iv) groundwater sampling. In addition, budget has been included to repair hurricane damage to the pump and treat system. Task 2. 1 Field Preparation Under Subtask 2 . 1 , GeoSyntec will conduct field preparation activities, such as acquisition of IRC right-of-way drilling permits, scheduling and staffing, subcontracting, and field equipment preparation. GeoSyntec expects to contract with a drilling company for the work described below. In addition, we will coordinate with US BioSystems, the analytical laboratory contracted with IRC , regarding laboratory analyses required by FDEP . Task 2. 2 Well Installation and Development Under Subtask 2 .2 , GeoSyntec will install and develop the following fie proposed monitoring wells : • GR-MW31B screened from 35 to 45 ft BLS and intended to monitor the northwest lateral extent of the CVOC plume ; • GR-MW32A screened from 5 to 15 ft BLS and intended to monitor the northwest lateral extent of the CVOC plume; • GR-MW32B screened from 35 to 45 ft BLS and intended to monitor the northwest lateral extent of the CVOC plume ; XR05010 IRC MPIS-PM Sampling\R050001J-rev.doc 40 RECYCLED AND RECYCLABLE r t . EOSYNTEC CONSULTANTS Mr. Tanhum Goldshmid Indian River County, Solid Waste Disposal District 3 May 2005 Page 5 • GR-MW30CC screened form 75 to 85 ft BLS and intended to monitor CVOC concentrations immediately above the confining layer in an area where hi torical DPT sampling revealed elevated cDCE concentrations (immediately down adient from excavated source area) ; and • GR-MW30VE a double-cased monitoring well screened from 105 to 11 C ft BLS and intended to monitor the vertical extent of the CVOC plume in the formersource area. The proposed monitoring wells identified above are intended to complete the monitoring network in the vicinity of the site and, as requested by FDEP , monitor CVOCs near the source area above and below the confining layer previously identified at the site . The well installation and development will be conducted in accordance with FDEP Standard Operating Procedures (SOPS) . Under this task, GeoSyntec will coordinate with FDEP for approval of the proposed well locations and screened intervals and to establish appropriate well construction details . This effort may include submission of applicable supporting data (grain size distribution analyses , in- situ hydraulic conductivity testing, depth to water, etc . ) to FDEP . This task will involve the installation of five (5 ) monitoring wells with a drill rig equipped with hollow stem auger (HSA) capabilities . The two deeper proposed monitoring wells, GR-MW30CC and GR-MW30VE, will be installed with mud rotary techniques, with GR-MW30VE completed as a double-cased monitoring well . The monitoring wells will be developed by surging and over-pumping. Protective barriers (i . e . , bollards) will be installed around each proposed monitoring well or well cluster that may be subject to damage by heavy equipment or traffic . After installation, each proposed monitoring well will be surveyed by a Florida Registered Professional Land Surveyor. Additionally, recently installed former source area monitoring wells GR-MW30A and GR-NIW30B will be surveyed. The budget estimate for this task also includes labor for waste characterization ; however, actual disposal of the waste will be handled by IRC 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/purge water, stage the drums on- site, and mark each drum to indicate the source of the waste ( . g. , boring XR05010 IRC MPIS-PM Sampling\R050001J-rev.doc RECYCLED AND RECYCLABLE r T EOSYNTEC CONSULTANTS Mr. Tanhum Goldshmid Indian River County, Solid Waste Disposal District 3 May 2005 Page 6 numbers, etc . ) contained within each drum, the generation date, and contact in rmation. If any of the development/purge water generated during field activities is generally free of particulates , this water will be treated by the on-site P&T system and not staged in drums . Waste characterization sampling and analysis will be performed consisteni 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 cutt ngs . These two samples will be submitted to US BioSystems for analysis by Toxicity Qlaracteristic Leaching Procedure (TCLP) for Resource Conservation and Recovery Act (RCRA) metals, VOCs (EPA Method 8260) , and semi-volatile organic compounds (EPA Method 8270) . The costs for laboratory analysis of the TCLP samples has not been included herein since it is anticipated that the laboratory analytical charges will be directly billed to IRC by US BioSystems . The analytical results 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 . If so requested, GeoSyntec can provide assistance with IDW disposal (meeting IRC staff, coordinating drum removal , etc . ) ; however, no budget is included for IDW disposal assistance . In addition, under Subtask 2 . 2 , budget has been included to repair hurricane damage to the pump and treat system, including purchase and installation of: (i) totalizers or recovery wells RW- 1 and RW-2 ; and (ii) a blower intake housing unit . Task 2. 3 Well Redevelopment A review of data associated with monitoring wells installed and sampled a part of the Targeted Brownfield Assessment (TBA) grant revealed that a number of wel s exhibited turbidities of greater than 1 , 000 nephelometric turbidity units (NTUs) . Elevat d turbidity readings may result in elevated detections of groundwater analytes . As reques led by IRC , this proposal includes labor and equipment for GeoSyntec to redevelop th following existing monitoring wells in an effort to remove fine-grained particles from the well casing and reduce the turbidity to acceptable levels (generally less than 20 NTUs) : G -MW24A, GR-MW24B , GR-MW26B , GR-MW27A, and GR-MW27B . The wells will be redeveloped by overpumping and surging. Field parameters , including pH, conductivity, XR05010 IRC MPIS-PM Sampling\R050001J-rev.doc C; RECYCLED AND RECYCLABLE r a EOSYNTEC CONSULTANTS Mr. Tanhum Goldshmid Indian River County, Solid Waste Disposal District 3 May 2005 Page 7 and turbidity, will be monitored by a GeoSyntec representative during t iis process . Extracted groundwater during the redevelopment process will be collected 4and pumped through the on- site air stripper for treatment . Task 2. 4 Groundwater Sampling GeoSyntec will perform the groundwater sampling activities associated with the MPIS network and the CVOC plume monitoring wells . Groundwater sampling activities will be executed using a two-person sampling crew. Groundwater sampling will be performed in accordance with the FDEP SOPS . Consistent field documentation and field p otocols will be utilized to develop reliable data to support the exit strategy and/or natural attenuation approach for the project . Task 2. 5 Water Level Measurements Under Subtask 2 . 5 , GeoSyntec will conduct a complete round of groundwater level measurements coincident with each semi-annual groundwater sampling event . Depth to groundwater measurements will be recorded to the nearest 0 . 01 -ft in the MPIS and CVOC plume monitoring network wells , a total of 100 monitoring wells (82 existing monitoring wells, three pumping wells, ten infiltration gallery wells, and five proposed monitoring wells) . Task 3 — Data Evaluation Under Task 3 , GeoSyntec will perform data evaluation activities for the MPIS and CVOC plume monitoring reporting. These activities will include database rr, anagement, data evaluation and screening, and geographical information systems (GIS) figure preparation. Task 4 — MPIS Reporting The results of groundwater sampling under the MPIS will be presented in a report supported by attachments containing Chain of Custody sheets, field notes and observations, water sampling logs , maps, analytical results, and any other applicable mateir als . These reports will be prepared under Task 4 and will be submitted to IRC for revi w prior to submittal to FDEP . According to the MPIS , monitoring test results must be submitted to XR05010 IRC MPIS-PM Sampling\R050001J-rev.doc q, RECYCLED AND RECYCLABLE r 1 a EOSYNTEC CONSULTANTS Mr. Tanhum Goldshmid Indian River County, Solid Waste Disposal District 3 May 2005 Page 8 FDEP within sixty (60) days of receipt of the analytical data from the laboratory. In addition, the report must be accompanied by a Ground Water Monitoring Repoil form. Task 5 — CVOC Plume Monitoring Reporting The results of groundwater sampling associated with the CVOC plume monitoring will be presented in a report supported by attachments containing Chain of Cusstody sheets , field notes and observations , water sampling logs , maps, graphs, analytical results , and any other applicable materials . This report will be prepared under Task 5 and will lie submitted to IRC for review prior to submittal to FDEP . The semi-annual CVOC Plume Monitoring Reports will be submitted to FDEP within sixty (60) days of receipt of the analytical data from the laboratory. In addition, the well installation activities will be documented in the initial semi-annual report, supported by attachments containing well completion forms , field notes, and observations . Task 6 — Quarterly Remedial System Reporting As outlined in the July 2003 RAP, letter reports will be prepared and submitted to FDEP on a quarterly basis . The reports will document : (i) laboratory analytical results for collected influent and effluent groundwater samples ; (ii) volume of groundwater extracted; (iii) graphs of influent and effluent concentrations versus time ; and (iv) any specific maintenance activities or system upsets . The budget for two years (eight report ng periods) of quarterly reporting has been included under this task . However, following t e first year of quarterly letter report submittals, the frequency of submittals will be re-evaluated and potentially reduced to semi-annually (with prior FDEP approval) . Sincesemi-annual groundwater monitoring reports for the CVOC plume monitoring network are prepared for the site (which include groundwater level measurements and monitoring wia.11 network sampling results) , the treatment system letter report submittals are intended to simply provide operational data associated with the expanded P&T system.
