Proposed Cross-Florida Barge Canal: Water Quality Aspects with a Section on Waste-Assimilative Capacity (open access)

Proposed Cross-Florida Barge Canal: Water Quality Aspects with a Section on Waste-Assimilative Capacity

Abstract: The route of the partly completed Cross-Florida Barge Canal follows the St. Johns, Oklawaha and Withlacoochee Rivers.

Chemical and Hydrologic Assessment of the Caloosahatchee River Basin, Lake Okeechobee to Franklin Lock, Florida

From purpose and scope: The U.S. Geological Survey, in cooperation with Lee County, conducted an investigation of the river in 1976-79. This investigation was planned to provide a broader base if information than heretofore available on the freshwater resources of the Caloosahatchee River basin, and in particular to provide information on water-quality conditions with emphasis on nutrients and algal growth. In addition to data collected during 1976-79, some earlier data collected by the U.S. Geological Survey were included to evaluate annual variation and trends.

Evaluation of a Proposed Connector Well, Northeastern DeSoto County, Florida (open access)

Evaluation of a Proposed Connector Well, Northeastern DeSoto County, Florida

Abstract: At a 24,000-acre citrus grove, a connector well is proposed as a resource management tool for capturing water normally lost through evapotranspiration and by excess runoff. Such a well would connect the surficial sand aquifer with the deep, highly transmissive limestone Floridan Aquifer. Because of natural head differences, water would move by gravity flow from the sand into the Floridan Aquifer, thus replenishing water withdrawn for irrigation from the Floridan Aquifer. A 70-acre marsh was selected as the test site based on analyses of hydraulic conductivity, porosity, and water quality. Recharge rate through the connector well under steady-state conditions is estimated at 160 gallons per minute. The proposed connector well is designed to have 10-inch screens opposite zones in the 45-foot thick sand aquifer, be cased for 400 feet opposite confining beds and a secondary limestone aquifer, and be open hole for about 250 feet in the Floridan Aquifer. A graded-sand filter pack placed around the screened sections of the well will increase its efficiency.

Chemical, Physical, and Radiological Quality of Selected Public Water Supplies in Florida, January-May 1979 (open access)

Chemical, Physical, and Radiological Quality of Selected Public Water Supplies in Florida, January-May 1979

Abstract: Most public water supplies sampled in Florida meet the National Interim Primary and Proposed Secondary Drinking Water Regulations. This conclusion is based on a water quality reconnaissance of 131 raw and treated public supplies throughout the State during the period January through May 1979. In a few public supplies, primary drinking water regulation maximum contaminant levels were exceeded for mercury, turbidity, and gross alpha particle activity. Secondary drinking water regulations were also occasionally exceeded in some public supplies for such parameters as chloride, pH, color, dissolved solids, iron, and manganese. These parameters, however, are more related to the aesthetic quality of drinking water than to public health aspects.
