Mehta, P.E Managing Director Solid Waste Disposal District Indian River County 132574 1h Avenue SW Vero Beach, Florida 32968 Subject: Proposal to Complete Remedial Action Plan Modification Addendum No. 3 Pre- Injection Investigation and Finalize Bioremediation Design Former South Gifford Road Landfill Vero Beach,Indian River County,Florida Dear Mr. Mehta: Geosyntec Consultants (Geosyntec) is pleased to submit this letter proposal to the Indian River County (IRC) Solid Waste Disposal District (SWDD) to provide professional services for Florida Department of Environmental Protection (FDEP)-required activities associated with continued implementation of the groundwater monitoring and remedial action for the chlorinated volatile organic compound (CVOC) plume at the Former South Gifford Road Landfill located in Vero Beach, Indian River County, Florida(Site). This fee proposal is based on discussions with the IRC and the pre-injection investigation required by FDEP (as outlined in Remedial Action Plan Modification Addendum No. 3 [RAPM3], which was approved by the FDEP on 15 July 2016). RAPM3 presented a bioremediation design and contingent injection event(s) to remediate the recalcitrant CVOC groundwater impacts in the former source area (vicinity of monitoring well GR-MW30B). Prior to implementation of the bioremediation design, and as outlined in RAPM3, a limited pre-injection groundwater investigation event(investigation) was proposed with the goal of refining the locations for the proposed injection activities in the vicinity of the former source area. This fee proposal presents the proposed scope of work and estimated budget to complete the investigation. Geosyntec has prepared this proposal (professional services as Exhibit 1) as Amendment No. 1 to existing Work Order No. 4 for the Continuing Contract Agreement for Professional Services between IRC SWDD and Geosyntec. The remainder of this letter provides a description of the proposed scope of work, a budget estimate, and a discussion of the schedule for accomplishment of the work described herein. XR16028 engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. GeosynteCcl 2 September 2016 consultants Page 2 PROPOSED SCOPE OF WORK The proposed scope of work consists of investigation activities to focus the treatment area presented in RAPM3. These activities include the following, which are further described below: (i) preparation for field activities; (ii) injection well redevelopment; (iii) injection well sampling; (iv) DPT groundwater sampling; and (v) project management. Prior to the commencement of field activities, Geosyntec will subcontract with a drilling company and mobile laboratory, update the site-specific health and safety plan (HASP), and coordinate with IRC regarding Site access. Field activities will include redevelopment of select existing injection wells (up to 36 wells), collection of groundwater samples from the injection wells, and oversight of direct-push technology (DPT) groundwater sampling. Redevelopment will be completed using surge and purge techniques in an effort to remove residual substrate injected during the implementation of RAPM (2008 and 2009) and RAPM2 (2011 and 2012). Groundwater samples will be collected from injection wells using low flow sampling techniques and field water quality parameters will be monitored during stabilization. Groundwater samples will be submitted to an on-site mobile laboratory for analytical analysis of CVOCs by EPA Method 8260. Analytical results reported for the groundwater samples collected via select existing injection wells will be evaluated while field activities are in progress and used to select locations for DPT groundwater sample collection. It has been assumed that the injection well re- development activities will be completed within one field day. Groundwater sampling of the existing injection wells and DPT groundwater sampling will be completed within four days. In accordance with RAPM3, Geosyntec will finalize the bioremediation design that was documented in RAPM3 based upon the results of the investigation to optimize implementation by providing both an economical and practical approach to meeting the long-term goals of the Site. The bioremediation design package to be provided to IRC SWDD electronically via email will include updated versions of the proposed injection location figure and dosing calculations specifying the amount of electron donor required that were originally presented to FDEP in RAPM3. In addition, summary text outlining the design approach will be provided to IRC for discussion. Pre-injection investigation efforts and related project management, including correspondence with IRC SWDD, invoice review, project coordination, and project administration are included within this proposal. Documentation of RAPM3 implementation will be included within the semi-annual groundwater monitoring report that follows implementation activities. Implementation of the injection activities and reporting efforts documenting implementation results are not included within this proposal.

The budget estimate presented in this proposal is based on Geosyntec's understanding of the project requirements, our experience gained from executing similar tasks for SWDD since 2002 at the Site, and experience with groundwater monitoring and data evaluation at similar facilities. Geosyntec will not exceed the budget estimate without prior approval and written authorization from IRC SWDD. CLOSURE Geosyntec appreciates this opportunity to offer our services.
