It is well recognized that the chemical forms of mercury in the water column and sediments are intimately related to bioaccumulation and body burden. Interactions of mercury and dissolved organic matter may play an important role in controlling the bioavailability and reactivity of mercury. The goal of our research is to provide information about the interactions of mercury and dissolved organic matter that will better define this important, albeit, poorly understood process. Ultimately, this research will lead to a more complete model of mercury behavior in the Everglades. Our research focused on the effect of DOC on the transport and reactivity of mercury in the Everglades through a combined field and laboratory study. The underlying hypothesis of this research is that the chemistry and structural characteristics of organic matter in the Everglades have a controlling influence on mercury cycling processes such as methylation and volatilization. The South Florida Water Management District, the U.S. Environmental Protection Agency, and the USGS South Florida Ecosystems Initiative have organized an intensive study of surface water chemistry in Southern Florida. In 1994, several onsite-research locations were selected in the Water Conservation Areas of the South Florida Water Management District in conjunction with this multidisciplinary, multiagency research project. 19950301 19950331 ground condition complete none planned -80.9 -80.1 26.79 25.59 none pH chemistry hydrology water quality ISO 19115 Topic Category environment inlandWaters 007 012 Department of Commerce, 1995, Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions, Federal Information Processing Standard (FIPS) 10-4, Washington, D.C., National Institute of Standards and Technology United States US U.S. Department of Commerce, 1987, Codes for the identification of the States, the District of Columbia and the outlying areas of the United States, and associated areas (Federal Information Processing Standard 5-2): Washington, D.

Data are available for samples collected in March 1995 and analyzed shortly thereafter. Surface water samples were collected at a single depth from 7 locations and at two depths at 3 locations. Marsh pore-water samples were collected at several depths below the sediment water interface at 4 locations. Surface water samples were collected at each pore-water sampling location. A replicate sample was collected from selected Everglades Study Sites to evaluate onsite-sampling variability. Distilled-water blank samples and standard reference water samples (SRWS) were submitted to the laboratory with the onsite samples and were analyzed concomitantly with them. Reference samples were processed using the same procedures as the onsite samples. A total of 27 samples from 10 locations from South Florida Water Management District Water Conservation Areas have been analyzed using a protocol designed to minimize errors associated with sample handling procedures, laboratory analyses, and data-entry operations. unknown George Aiken U.S. Geological Survey Project chief mailing address
