(JLA) is pleased for the opportunity to assist Indian River County Parks, <br />Recreation and Conservation Department (IRC) with hydrogeologic consulting services. The IRC <br />North County Aquatic Complex (NCAC) operates a closed loop heat exchange system to regulate <br />water temperature utilizing water from the Upper Floridan Aquifer (UFA). Recently the UFA <br />supply well started producing substantial quantities of sand and has made the heat exchange <br />system inoperable. A recent downhole investigatory video and testing scope identified multiple <br />failures in the supply well casing. It was determined that the well could not be repaired and needs <br />to be immediately abandoned. A replacement UFA supply well is needed to restore operation of <br />the heat exchange system. <br />Outlined below are the specific tasks included in our proposed scope of work, along with the <br />associated costs for your thorough review and consideration. Our dedicated team is committed <br />to delivering outstanding results, ensuring the project maintains the highest standards of quality. <br />1.0 NCAC UFA Replacement Supply Well Siting and Design — Provide hydrogeologic services, <br />for siting and well design of replacement UFA heat exchange system supply well at the IRC <br />NCAC. <br />Well siting will include desktop review of existing site plans to be provided by IRC to <br />identify potential locations for a replacement UFA supply well and a replacement UFA <br />return well if needed for future planning purposes. Following the desktop review and <br />identification of potential locations, JLA will meet with IRC staff onsite to finalize the new <br />well location(s). Replacement well siting will take into account site access, pipeline re- <br />routing and site constructability by a State of Florida certified water well drilling <br />contractor. <br />jlageosciences.com <br />169 <br />
