GTA evaluated existing groundwater supply well field drawdown, pumpage and test data, and prepared a work plan for well field testing. Performed operational 90-day well field testing to evaluate system performance and as a basis for providing recommendations on optimization of groundwater withdraws. The test consisted of simultaneously pumping eight wells during a 90-day test period, observing groundwater level responses and logging flow rates. GTA analyzed well performance, potential well interference and pumping/drawdown data in the context of system constraints. GTA provided an estimate of sustainable well field yield, and provided recommendations on optimization of well performance.
