Winflow or AnAgSim) are more complex but still relatively easy to set up. Finite -difference and finite - element models (Modflow and FEFLOW) are more difficult to set up but can address much more complex conditions. Cost of modeling generally increases with complexity. When we have an option, we choose our groundwater models based on the needs of each project, requirements of the regulators, time available and cost. Since January 2010, we have used analytic models to help us select the pump and design pumping level of 2 public supply water wells in Okeechobee County, used an analytic model to predict the future impact of a public water supply well system in Martin County, and served as a consulting expert to review the design of a numeric Modflow model to determine if it accurately predicted the water -table drawdown around a major wellfield (PBC System 9) in Palm Beach County, and served as a consulting expert to SJRWMD to review the design of a Modflow model in Volusia County, Florida. Field Services and Testing "Going in the field" is typically the first assignment for a junior geologist. We provide field services at a competitive fee but much greater level of expertise. Two examples of projects we have performed are onsite hydrogeologic services during construction of 2 public water supply wells at the Fort Drum Service Plaza on Florida's Turnpike, and coordination of the construction of irrigation wells on Jupiter Island. For both projects, our responsibilities included interpreting drilling reports and data, and test data to recommend and assist in selecting the completion depth and screen interval that would produce at the optimal rate and deliver a stable water quality. Consulting Expert and Expert Witness We have been involved several times in cases involving potential litigation. In many cases, a Tessier Consulting, LLC representative consults during pre-trial proceedings, advising the attorney about the additional materials that need to be obtained, and the inquiries that need to be made of the deposed. In other cases, a Tessier Consulting, LLC, representative may also serve as a testifying expert. In preparation for trial or administrative hearing, the testifying expert may review all pertinent data, reports and test results, prepare an expert witness report, testify regarding site conditions, and assist the attorney with post -verdict filings. We were requested to review data and records compiled during construction of 2 Floridan Aquifer wells for public water supply in the Town of Manalapan. The case involved the potential liability of a hydrogeologic consulting firm in the design, construction and testing of the wells. Although both wells were constructed to the same specifications, one of the wells produced at half the pumping rate of the other well. Tessier Consulting, LLC, reviewed the available construction logs and test results and advised the Town's attorney regarding the appropriate inquiries during depositions of the key players. 116
