Description:

Abstract:

The data are for dissolved organic carbon (DOC) and specific ultraviolet absorbance (SUVA) for surface water and pore water in the South Florida Water Management District (SFWMD) water conservation areas.

Purpose:

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 methylamine 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, multiage research project.

Process_Description:

Samples from select sites (ENR, STA 2, WCA-1, WCA-2, and WCA-3) were collected in June 2005 and were analyzed. The samples are part of a long term monitoring effort to identify changes in the concentration and chemical reactivity of dissolved organic matter (DOM) in the Everglades.

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 each pore-water sampling location. A replicate sample was collected 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 concurrently with them. Reference samples were processed using the same procedures as the onsite samples.
