A new University of Georgia study finds that sewage-contaminated groundwater is reaching the offshore reefs of the Upper Florida Keys, possibly threatening corals and human health.
"The widespread use of in-ground waste disposal through septic tanks and injection wells appears to be leading to the contamination of submarine groundwater even up to six miles offshore," said study author Erin Lipp, associate professor at the UGA College of Public Health. "When the contaminated groundwater mixes with surface water and reaches the reef, the corals as well as human health might be harmed."
The findings were presented Tuesday at a meeting of the Florida Keys National Marine Sanctuary Water Quality Protection Program Steering Committee in Marathon, Fla.
Lipp and doctoral student Carrie Futch, along with Dale Griffin of the U.S. Geological Survey in Tallahassee, sampled surface water, groundwater and corals from five sites from nearshore to offshore beginning outside of Port Largo Canal and ending near Molasses Reef. Their three-year study revealed common fecal indicator bacteria and human viruses.

Emergency services evacuated hundreds of homes in the university city of Oxford today as the River Thames broke its banks and Britain grappled with its worst floods in 60 years.
Water levels rose steadily overnight and police said they had cleared up to 250 homes and gave people shelter in Oxford City's soccer stadium. Some power was cut but the defences of the local electricity substation were not breached.
Along the Thames, residents in other towns were warned that the river could go on rising throughout the day.
