State water managers have proposed seizing 40, acres of private- and state-owned wetlands that would be used as a natural purification system to filter out nutrients before they reach sensitive areas.

In the short run, this may require trade-offs in balancing water quantity needs with water quality challenges, because much of the available water contains contaminants.

After being elected, Broward imposed a state land tax in order to finance his project, announcing that the drainage would be an easy job to do and last no longer than eighteen months.

These experts decided on a radically different approach and adopted a new engineering project focused on flood control more than drainage in order to prevent hurricanes from blowing water out of the lake.

This summer, for the first time, fish in most parts of the Everglades have been declared unsafe for eating, because of mercury contamination.

Scientists have discovered that south Florida receives some of the highest levels of mercury deposition in the United States, mostly in rainfall. The Florida panther, the most highly endangered mammal in the U. Davis, Jack E.

Inthe State Everglades Forever Act consisted in a massive effort to improve the water quality in the Everglades, with the aim of reducing the level of phosphorus runoff from the sugarcane fields thanks to treatment areas Levin, A reevaluation of the design of Stormwater Treatment Areas might lead to improved sulfate removal processes.

The idea was to use the sugar land to construct a network of reservoirs to clean and store water before sending it south into the Everglades National Park. These data, they say, provide ample evidence that air pollution is the prime cause of mercury contamination in fish and that stringent emission regulations are tackling the problem.
