Advertisement Detail Request for Proposal Field Evaluation of In-Lake Treatments to Reduce Water Column Phosphorus in Lake Jesup Advertisement Number: 37042 Version Number: 000 Advertisement Begin Date/Time: 08/17/2021 - 02:00 P.M. Advertisement End Date/Time: 09/07/2021 - 02:00 P.M. Mod: 08-17-2021 02:55:20 Last Edit: Tuesday, August 17, 2021 at 02:55:53 P.M.
Selection of the optimal approach for limiting whole lake recycling of sediment P for a water body the size and scale of Lake Jesup necessitates the phased testing that will evaluate 1) the efficacy of the chemical itself under controlled conditions, and 2) the performance in situ. This testing will evaluate each amendment’s effectiveness on reducing the sediment flux of P into the water column , the changes in fractionization of sediment P, the speed of effect and duration of effectiveness, the potential toxicity effects on aquatic organisms, and the cost. It was proposed to undertake this evaluation in a two-phased investigation: a phase 1 laboratory bench-scale assessment, and a phase 2 in-lake mesocosm trial. The phase 1 bench-scale assessment was completed in February 2021. The work associated with this scope of work is the Phase 2 in-lake mesocosm trial. The phase II work will evaluate the amendment’s effectiveness on reducing water column P concentration, the changes in fractionization of sediment P, the speed of effect and duration of effectiveness, the potential toxicity effects on aquatic organisms, and the cost in outdoor mesocosms. Request for Proposal will be opened at the below address at 02:00 P.M., September 07, 2021.
