Ground waters are potential sources, sinks, and carriers of nutrients and other contaminants beneath the Florida Keys and offshore regions to the north and south. This project is designed to provide new data on the sources, flow directions, exchange rates, and chemical characteristics of ground waters underlying the region of Florida Bay, the Keys, and offshore reefs. The results, to be derived in part from analyses of environmental tracers and isotopes, will provide general empirical information about subsurface transport processes and their potential impact on surface water chemistry.

The major accomplishments for FY98 were an intensive sampling effort in November, 1997 and subsequent analytical work on the samples. Approximately 1200 samples were collected from about 40 sites, mainly in Florida Bay, and including a few representatives of surface waters, water supplies, and nested piezometers. This sample set complements the one obtained in FY96 by extending the coverage of the project throughout Florida Bay, by including more vertical resolution at selected sites, and by including some shallow ground waters and seepage meters at one of the ocean-side experimental tracer sites.
