INDIAN RIVER COUNTY, FLORIDA AGENDA ITEM Parks, Recreation & Conservation Department Aquatics Division Date: January 13, 2025 To: The Honorable Board of County Commissioners Thru: John A. Titkanich, Jr., County Administrator Michael C. Zito, Deputy County Administrator Beth Powell, Parks, Recreation & Conservation Director CONSENT AGENDA BCC Meeting 01-28-2025 From: Gustavo Vergara, Assistant Director - Parks, Recreation & Conservation Subject: North County Aquatic Center Source Phase H Well Replacement BACKGROUND: On November 5, 2024, the Board of County Commissioners `BOCC" approved up to $223,146 for exploratory and remedial work to be completed on the existing source well that provides water to the geothermal heating/chilling system at the North County Aquatic Center. On November 22, 2024, JLA Geosciences Inc. Hydrological Consultants "JLA", oversaw Centerline Drilling performed the needed video scope of the well to assess the current condition. The Staff Report from the Board meeting held on November 5, 2024, is attached for reference (Attachment 1). A technical memorandum of the findings is outlined in Attachment 2 and it concluded the following: • Existing supply well is damaged beyond repair and needs to be abandoned by a Florida certified water well driller. • Based on observations made during the supply well video it is recommended IRC perform a similar downhole well video investigation on the existing UFA return well to determine condition of casing. • Siting, permitting, design and construction of a replacement UFA supply well and return well if necessary, should begin immediately. A performance test of the well was also completed and because of the complete collapse of the casing of the well, the Gallons Per Minute "GPM" coming out of the well was measured at 195 GPM, which was 105 GPM short of the needed 300 GPM needed to effectively operate the heating/cooling system. The system was sucking so much sand and rocks that it had obstructed the pump impeller which assists the well in pumping the necessary GPM to the system. JLA submitted a proposal to oversee the capping/abandonment of the well for $14,772 (Attachment 3). Staff was able to apply to the St. John's River Water Management District's "SJRWMD" abandoned artesian well plugging program, where they will cap the well at no cost to the County. On December 11, 2024, Gary Foster, Senior Hydrologist with SJRWMD communicated that the work could be performed through their program this winter. On January 13, 2025, staff confirmed that the 158
