JACKSONVILLE, Fla. -- Toxic green algae, polluting nutrients and floating garbage in the St. Johns River.

But a team of Jacksonville University scientists and other conservation groups are working to with the city to help clean it up.

Dr. Quentin White with the Marine Science Research Center invited our cameras out with him as he prepares the river floor for a major renovation.

"We'll run it through a sediment sampler," he said.

With $50,000 in state grants and money from the Coastal Conservation Association, concrete reefs will be dropped into the bottom of the St. Johns with the hope of improving its water quality.

"By putting this kind of concrete rubble down, it promotes barnacles oysters other kind of marine life that helps filter the water helps clean it and also promotes the production of more fishing habitat," White said.

Today, White searched for the perfect spot for the new reefs near the fuller warren bridge.

"We're going to be probing the bottom trying to figure out how soft it is you don't want to put a bunch of concrete down where it sinks to."

Once installed you may not be able to see the reef at the depths of the River City but it will make a big splash on the health of the environment.
