Upper ¡Floridan ¡Aquifer ¡Regional ¡ Recharge ¡Concepts ¡Update ¡ Task ¡1 ¡ ATKINS ¡Technical ¡Memorandum ¡No. ¡1 ¡

Focus • Summarized accumulated hydrologic/ hydrogeologic data • Identified regulatory and water treatment requirements • Identified water treatment processes for the ranges of surface water and reclaimed water sources

Potential Recharge Water Sources • Upper Suwannee River • St. Mary’s River • Ocklawaha River • St. Johns River • Black Creek • Various potential reclaimed water sources

Treatment Requirements & Processes • Regulatory and Treatment Requirements: Ø Direct aquifer recharge (aquifer recharge wells): ü Surface water: must meet primary and secondary drinking water standards ü Reclaimed water: difficult to permit under existing regulations

Treatment Requirements & Processes (cont.) • Indirect aquifer recharge (Rapid Infiltration Basins [RIBs], reservoirs, sinks, wetlands, or storage ponds): ü Surface water: no specific treatment regulations; however , FDEP reserves the right to review on case-by-case basis ü Reclaimed water: more restrictive than for surface water, but may be achieved (more to come – Task 2)

Next Steps • Task 2 summary: ü conceptual design for four regional recharge concepts ü recharge benefit assessed using the District’s revised North Florida Model
