RESUME GREG F. RAWL, P.G. EXPERIENCE SUMMARY: Mr. Rawl has over 25 years of experience in the fields of water resources, hydrogeology and geology. He has managed projects throughout the North American continent within the realms of these disciplines. He has a broad base of expertise as a result of his background as the Senior Vice President of a specialty underground construction firm, a principal geologist for multi-disciplined engineering firms and a supervising manager for a regulatory agency directly involved with allocating water resources. He is recognized as an expert in the design, simulation and construction of trenched horizontal wells. Mr. Rawl’s experience covers large scale analysis of surface water and groundwater systems throughout all the phases of a project: cost estimates, design, regulatory permitting, groundwater flow and solute transport modeling, data evaluation, report preparation, and field supervision. He has also served as a consultant in areas such as water supply, groundwater cleanup, remedial action plans, effluent reuse, landfills, seepage studies, watershed simulation modeling, dewatering and dredge/fill projects. In addition, he has served in both a technical and managerial capacity with a regulatory agency spanning a sixteen-county area of South Florida. He has been used as an expert witness in cases involving groundwater and surface water resources. EXPERIENCE BACKGROUND: • Mr. Rawl is currently conducting the Groundwater Recharge and Mining Study for Lee

County. The study will be the most comprehensive evaluation of the hydrogeology of Lee County completed to date. As part of the study a detailed database of the hydrogeologic and geologic properties of Lee County will be compiled for incorporation into a County wide groundwater flow model. The database will also be used to define commercial mining deposits throughout the County. Aerially specific recharge rates to the surficial aquifer system will also be determined to define where significant recharge is occurring. The impact of future water uses and potential mining scenarios will also be assessed.

• Mr. Rawl is evaluating the DR/GR land use category for the eastern half of the City of

Bonita Springs. Specific emphasis is being placed on the groundwater recharge potential of the DR/GR land use category and the implications of the potential future incorporation of alternative land use categories in the study area. Additionally the surface water impacts of the existing land uses are being analyzed to determine if implementation of alternative land uses with the incorporation of Best Management Practices are feasible in the study area. Evaluation of the impacts of surface water discharges from the area on the downstream receiving water bodies of the Imperial River and Estero Bay are being simulated with surface water models. Ultimately recommendations will be provided to the City pertaining to future growth in the area.

• Mr. Rawl is providing continuing water supply planning, design, permitting and construction/operational assistance for Shell Point. Shell Point was created in the early 1960’s and is currently undergoing a $750 million expansion with the creation of a new campus. It is located in an area of Lee County, Florida that is severely limited in freshwater resources. Mr. Rawl has designed a water supply system that serves the irrigation needs for the project and the water supply need for the Central Energy Facility (CEF) using the best available water quality from the Floridan Aquifer. The Shell Point CEF when completed will be the largest such facility in the southeastern United States. It provides all of the heating and cooling needs of the project utilizing a hydronics distribution system. Numerous cooling towers are utilized for heat exchange purposes; consequently a significant water supply demand with water quality limitations exists to meet its needs. Mr. Rawl designed and permitted a blowdown reuse system for the project that reuses the blowdown water from the cooling towers as part of the irrigation system for the Golf Course. Mr. Rawl has also been tasked with remedation of bacterial contamination of the closed loop hydronics system.

• Designed, permitted and provided construction oversight of the water supply system for Bobcat Trail Development located in Charlotte and Sarasota Counties, Florida. The system utilized three shallow trenched horizontal wells installed in a thin low hydraulic conductivity surficial aquifer to meet the demands of a consolidated water supply system serving a 18 hole golf course, the development common areas and the single family residences. The system was designed to minimize on-site drawdown impacts by inducing infiltration from an adjacent surface water drainage feature. The system provides the maximum day irrigation demand of 720,000 gallons from the horizontal wells. The water is discharged to an on-site surface water body for removal of the dissolved iron from the groundwater prior to the application of the water for irrigation. The other water supply option that was considered for the project was the use of the Lower Floridan Aquifer. This option was discounted due to the high cost of deep vertical well construction, low aquifer yield and poor water quality.

• Designed numerous systems for the development of potable and irrigation water supplies in areas where water resources are limited.

• Served as Project Manager and provided a value-added design for the most complex funnel and gate installation to date, which consisted of a series of HDPE barrier walls and four permeable reactive iron gates. The project was for Hercules, Inc. in Burlington, VT.

• Project Manager for the design and installation of an extraction system and barrier wall at a Texaco oil refinery along the Platte River in Wyoming.

• Designed a dual-phase horizontal extraction system installed at Miami International Airport working in conjunction with OHM Corp.

• Served as Project Manager for the extraction system installation at the Fairbanks Superfund Site near Gainesville, FL, where trenched horizontal extraction wells were installed to depths of up to 50 feet below land surface.

• Provided expert witness services pertaining to a Chapter 120 F.S. hearing for the South Florida Water Management District (SFWMD) regarding the interaction of surface and groundwater for a proposed agency action over a surface water management system permit.

• Supervised the groundwater flow modeling, water supply development and water use permitting associated with the Broward County North System Regional Wellfield, Broward County District 2A Wellfield, Martin County Vista Salerno Wellfield, and St. Lucie County Wellfields.

• Served as a Supervising Professional, Water Use Division, SFWMD, responsible for overseeing technical integrity and managing the staff of regulatory personnel. In this position he was involved with the consumptive use permitting of both groundwater and surface water for a sixteen-county area of south Florida, providing technical reviews, water shortage management policies and long-range planning.

• Represented the SFWMD through technical conferences and workshops and served on various advisory committees, such as the Technical Advisory Committee for Underground Injection Control for deep injection wells within the District. Worked on the Demand Management Team that developed the SFWMD's Demand Management Guidelines (1990).

• Served as the Senior Geologist for one of the largest multi-disciplined consulting engineering firms in the State of Florida, focused in the area of groundwater supply development and contamination remediation.

• Under contract to the SFWMD, Mr. Rawl conducted the first phase of the wellfield siting evaluation in Osceola County to determine the best available water quality to provide Brevard County with an alternative raw water supply. The project, known as the Osceola-Brevard Interdistrict Transfer, was ultimately stopped after the completion of the first phase by legal action taken by Osceola County.

• Responsible for assessing the contamination, modeling the plume movement using a flow and solute transport model, and development and implementation of the remedial system for the largest single TCE plume in the state of Florida for the City of Vero Beach.
