Tessier Consulting, LLC Hydrogeologic and Hydro -Environmental Services The firm was established in January 2010. Since that time, the firm has provided consulting services for a broad range of projects, including consumptive water use permitting, well permitting and design, groundwater modeling, dewatering plans and permits, litigation support and expert witness services. In addition, we consult on problems related to flooding, dewatering and groundwater control; sinkholes and settlement; wastewater disposal and reclaimed water application; lateral saltwater intrusion and saltwater upconing; drainage and groundwater/surface water interaction. Our clients range from private developers, farmers, ranchers, attorneys, and insurance companies to Federal and state agencies, counties, municipalities and utilities. In the short time the firm has been established, we have been involved in diverse projects that are professionally challenging, personally satisfying and beneficial to our clients. Some of our services are described below. Design and Construction of Facilities and Forensic Analysis of Underperforming Facilities Planning and design of new facilities must never be minimized in favor of changes during construction. Many construction projects are stalled or even "red tagged" because of a lack of planning and overlooked permit requirements. For example, we frequently receive calls from contractors who have undertaken construction without securing the proper dewatering permits either from the Water Management District or local environmental agencies with jurisdiction. Even for projects that have secured dewatering permits properly, failure to consider the discharge and the potential flooding nuisance can shut down even a simple project. Post -construction flooding caused by an unanticipated rise in the water table or concrete loading above the water table have caused problems in parking garages and even retail centers. In one project, a certificate of occupancy was withheld because the load created by a newly poured concrete floor above a shallow water table in a strip shopping center caused "wicking" of the water table through the vapor barrier and into the building. Well Site Selection and Conceptual Well Design Site selection and conceptual well design are the initial key elements leading to the bidding and construction of water supply wells. Well site selection considers proximity to existing raw water transmission lines, separation from sanitary hazards and known or potential sources of contamination, access, and potential for noise or disruption during construction. Conceptual design involves selection of materials and depth to maximize well performance and long-term operation. For East Central Florida Services, we identified materials, well size and depth which would produce irrigation water for many years. At the Fort Drum Service Area on Florida's Turnpike, we made recommendations to modify the previous well design to reduce the potential for borehole collapse due to the unexpected presence of unconsolidated material. Groundwater Modeling Groundwater models are typically developed to simulate site conditions in the past, present or future. Application of the appropriate groundwater model (analytic, analytic element, finite difference, finite element) varies with the type of model and the conditions being simulated. Analytic models (such as Theis or Hantush-Jacob) are the quickest to design and set up. Analytic element models (such as 115
