This document is a Task Assignment Notification Form for Florida Department of Environmental Protection (FDEP) Contract No. WM946, executed between FDEP and URS Corporation Southern (a subsidiary of AECOM). The contract involves a dye tracer study for the Jackson Blue Spring and Merritt's Mill Pond spring basins in Jackson County, Florida. Key subcontractors include Karst Environmental Services and Ozark Underground Laboratory. The study is designed to assess hydrogeologic connections between three dye introduction points and seven spring vents to better understand groundwater flow and nutrient transport mechanisms within the spring contribution areas.

The fixed-price contract is valued at $75,663.20 for a six-week sampling regime, with execution scheduled through June 30, 2016. Work is divided into four sub-tasks: site access and planning (including HASP, dive plan, and operational protocols); background sampling and dye introduction using three dyes (eosine, rhodamine WT, and fluorescein); six weeks of sampler collection and laboratory analysis at ten monitoring stations; and data review and final report preparation. An optional expansion of four additional weeks of weekly sampling is available at $2,536 per week to observe subsequent dye pulses through the aquifer system. Laboratory analyses are priced at $43 per sample with dyes provided at $50/lb. Funding is drawn from Florida water quality monitoring accounts with the cost breakdown detailed in Attachment C. The contract includes provisions for site access agreements with property owners, health and safety protocols, and coordination with local agencies including Jackson County Health Department and Northwest Florida Water Management District.
