The objective of this research was to determine the rate, direction of flow, and contamination levels of saline groundwater in the Florida Keys and Florida Bay. Contamination studies are necessary to determine if nutrient and other contaminant levels are rising and to provide a baseline of data for future decision making.

The well clusters were completed so that all of the piezometers were 100 ft (30.3 m) away from the central well. The central well became the location for the injection of dye to trace the natural gradient of groundwater flow. Fluorescein was injected in the shallow, central piezometer and Rhodamine WT was injected in the deep, central piezometer. The central well for the bayside cluster is approximately 75 m offshore.
Values for the dyes are ppb.
