Description:

Abstract:

This study supports several of the projects listed in the DOI science plan. The study supports the Comprehensive Integrated Water Quality Feasibility Study in the Landscape Science needs of the DOI Science Plan (p. 85), by examining links between water quality and ecosystem structure and function, identifying degraded parts of the ecosystem and quantifying links to contaminants (nutrients, sulfur, organics, and mercury), and investigating the impacts of ASR on the ecosystem. It also addresses risks to wildlife from soil-borne contaminants (sulfur, mercury, organics), through studies of the effects of dry/rewet cycles (Threats Associated with Rehydration of Agricultural Lands, p. 87; Predicting bioavailability of mercury (methylation) following inundation of dry land based on soil and water chemistry, p. 89) on methylmercury formation in STA's. The study supports the Arthur R. Marshall Loxahatchee NWR Internal Canal Structure Project by addressing the impacts of water quality (sulfur/nutrients/mercury) and water management practices on refuge resources, p. 40. The study addresses the Combined Structural and Operational Plan (CSOP) and the Water Conservation Area 3 Decompartmentalization and Sheetflow Enhancement by addressing the potential for increases in toxic contaminant loads (especially sulfur) and its ecological impact, p. 71. Overall, the synthesis report will seek to provide a integrated picture of these critical contaminants in the south Florida ecosystem, but also help to identify possible means toward improving conditions in the future through optimal land management decisions.

Purpose:

The objective of this project is to produce a synthesis report on contaminants in the Everglades, specifically focusing on the major contaminants of concern: nutrients, sulfur, mercury, and organics. This project links directly to the “Integrated Biogeochemical Studies of Contaminants in the Everglades”, and “Interactions of Mercury with Dissolved Organic Carbon in the Everglades” projects of the GEPES Program, which are the science projects providing the information for this synopsis report project. The project is subdivided into three Tasks. Task 1 will produce a mercury synthesis, with David Krabbenhoft as the lead. Task 2 will concentrate on sulfur and nutrients, with William Orem as the lead. Task 3 will develop the role of dissolved organic carbon (DOC) in methylmercury production, and changes in DOC associated with contaminants entering the Everglades, with George Aiken as the lead
