Wellfield Siting, Permitting, and Installation for the Department of Children and Families
   Florida

Overview
At a state operated assisted living facility Water & Air staff helped to locate, permit, and oversee the construction of a new potable wellfield that included five Floridan Aquifer wells. As part of the water use permitting process, a temporary consumptive use permits (TCUP) was required to install one of the future water supply wells to conduct aquifer performance testing (APT), geophysical testing, and well logging as required by the water management district (WMD) prior to obtaining an approved consumptive use permit (CUP). These testing methods were conducted at a State Assisted Living facility to obtain hydrologic parameters needed for hydrologic modeling and to physically monitor potential impacts caused by groundwater withdrawals on natural resources and the environment.

As part of this work Water & Air prepared the bid specifications for the project, held pre-bid meetings with drilling subcontractors, and helped State Employees select a drilling sub-contractor. Water & Air also reviewed project milestones and verified drilling expenses and requested payment draws. Water & Air staff designed the well construction procedures, supervised construction of five Floridan Aquifer potable wells, and oversaw aquifer performance testing conducted at each of the well locations. Water & Air staff performed analysis and interpretation of APT results and utilized this information with the computer Model MODFLOW to establish optimum pumping schedules for each well within the wellfield. Computer modeling was also utilized to verify no off-site impacts would occur as a result of operating the new wellfield, and to predict that the new wellfield would not pull in contaminant from the old wellfield location.

Results
Our experience with hydrologic testing, working with the WMDs, and negotiating reasonable water use permit conditions and sub-contractor contracts resulted in the subject well field being successfully installed with minimum RAI requests and project cost overruns, thus saving the client significant time and money.
