Summary
Rainfall events cause episodic discharges of contaminated groundwater into the near shore waters of the Florida Keys. Discharges enhance eutrophication in sensitive coral reefs. After the storm water discharges, hypoxia has been observed in all study stations in sea grass and coral reef areas of the Big Pine Key. In Port Pine hypoxia has caused mortality of benthos.
