Altitude and generalized configuration of the top of the Floridan aquifer, St. Johns County, Florida
Rick M. Spechler
1983, Water-Resources Investigations Report 83-4101
The Floridan aquifer is the principal source of freshwater to wells in most of St. Johns County. The aquifer consists of a thick sequence of interbedded limestone and dolomite of Eocene age. The top of the Floridan aquifer, which is irregular throughout St. Johns County, ranges from less than 90...
Potentiometric surface of the Floridan Aquifer and its use in management of water resources, St. Johns River Water Management District, Florida
Harry George Rodis, D.A. Munch
1983, Water-Resources Investigations Report 83-4176
The Floridan aquifer supplies most of the fresh groundwater for municipal, industrial, and agricultural uses within the 12,400 sq mi St. Johns River Water Management District. Because of the growing demand for water and the variation in rainfall, resource managers need timely information on short-term and long-term changes in the...

Shallow ground water in the Boulder-Fort Collins-Greeley area, Front Range urban corridor, Colorado, 1975-77
Paul A. Schneider Jr.
1983, Water-Resources Investigations Report 83-4058
Shallow ground water may limit the location of construction and excavation projects in parts of the Front Range Urban Corridor. A shallow water table occurs from 0 to 50 feet below the land surface principally in the alluvial deposits along the streams and rivers in the Boulder-Fort Collins-Greeley area. This...

Water-level maps of the alluvial aquifer, northwestern Mississippi, September 1982
Daphne Darden
1983, Water-Resources Investigations Report 83-4133
Water levels were measured in about 500 wells in the Mississippi River valley alluvial aquifer in northwestern Mississippi during September 13-24, 1982. The water-level change from September 1981 to September 1982 showed some recovery, but the depth-to-water map showed areas of continual water-level decline in the central part of the...
