This document is a task assignment change order for a Florida Department of Environmental Protection (FDEP) contract with AECOM, through its subsidiary URS Corporation Southern, for a Statewide Onsite Wastewater Study Phase II. The contract (WM946) involves monitoring well installation and groundwater sampling at six biosolids land application sites across central Florida, with work divided into two phases (Group II, Phase 1 and Group II, Phase 2). The sites are located in Putnam, Polk, Gilchrist, and Marion counties, and include facilities such as Turner, Byrd Septic Service, Affordable and Mann Septic, Jones Land Spreading, Couture Farm, and Averett Septic Tank Co.

The task assignment involves multiple sub-tasks including site reconnaissance, utility location, health and safety plan (HASP) preparation, monitoring well installation, top-of-casing surveys, and groundwater sampling. AECOM will use Huss Drilling as a subcontractor to drill and construct monitoring wells at the sites. The total project budget is $165,620.10, covering activities for both Phase 1 and Phase 2, with the budget broken down into specific sub-tasks such as site setup, well installation, surveys, and reporting. The work is to be completed over approximately 24 weeks, with specific start and end dates for each sub-task, and involves collecting groundwater samples to be analyzed for various parameters including sucralose, ammonia, phosphorus, and isotopes.
