This is a background document related to Lake Tarpon, a surface water source under consideration by the County for the Chesnut Aquifer Storage and Recovery (ASR) and Managed Aquifer Recharge (MAR) Surface Facilities project in Florida. The document provides hydrogeological and water quality baseline information on Lake Tarpon to support the engineering design, permitting, and construction oversight of surface facilities necessary to collect and treat surface water from this source. The project involves designing infrastructure to collect surface water, treat it to meet regulatory requirements, and route treated water to the existing ASR well and MAR well, with a potential bypass option to directly feed treated water to the North County Reclaimed Water System (NCRWS). The MAR well construction is expected to be ongoing during initial project phases and scheduled for completion in 2027.

The document establishes the environmental and hydrogeological baseline conditions of Lake Tarpon that will inform project design decisions and permitting requirements. This background information is essential for the engineering team to understand water quality characteristics, potential treatment needs, and environmental impacts associated with utilizing Lake Tarpon as a surface water source for ASR/MAR operations. The technical details contained within support the county's planning and design efforts as the project progresses toward construction and implementation phases.
