Purpose, Scope, and Source of Funding

The purpose of this report is to interpret results and develop final conclusions of an investigation of surface-water and ground-water interactions and their effect on the mercury budget in the north-central Everglades. The overall goals of the project were to:

1. quantify ground-water recharge and discharge in the ENR and WCA-2A,
2. determine relative importance of geologic,climatic, and water-resources management in affecting ground-water recharge and discharge, and
3. use improved estimates of ground-water recharge and discharge to develop accurate hydrologic budgets and chemical mass balances for mercury in the two areas.

A previous report (Harvey and others, 2000) contains detailed study methods and complete data sets covering all topics, including borehole drilling, geophysical measurements, sampling of ground-water geochemistry, and design and operation of shallow piezometers and seepage meters. The present report and the report by Harvey and others (2000) constitute the final deliverables for Cooperative agreement C-6661 between USGS and the South Florida Water Management District. Funding for the investigation also came from the USGS Place-Based Studies Program.
