Description
The St. Johns River Water Management District is seeking proposals from qualified firms to study sediment bioavailable phosphorus treatment with lanthanum-modified bentonite for Lake Jesup. The project includes sediment sampling, data collection, permitting, community outreach, treatment application, and post-treatment monitoring. The selected firm will be responsible for completing all tasks assigned to it and complying with all applicable requirements and conditions set forth in the Funding Grant.

• The firm will develop a written strategy that includes a detailed task-based approach for planning, permitting, implementing, monitoring, and assessing the success of the sediment treatment.
• The firm will coordinate with District staff to refine the strategy's tasks prior to initiation of each task.
• The firm will obtain all required permits and implement sediment treatment for Lake Jesup in accordance with the approved, permitted treatment plan.
• The firm will perform post-treatment monitoring of sediment phosphorus fractions according to the approved and permitted Treatment Plan and in accordance with the approved Quality Assurance Project Plan (QAPP).
• The firm will submit quarterly progress reports and a final report including sampling results, the Treatment Plan, and details of the treatment application.
