Potentiometric surface of the Floridan Aquifer in the St. Johns River Water Management District and vicinity, Florida, May 1982
George R. Schiner, Eugene C. Hayes
1982, Open-File Report 82-915
This map presents the potentiometric surface of the Floridan aquifer in the St. Johns River Water Management District and vicinity for May 1982. The Floridan aquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1,000 wells and on several springs. The potentiometric...

Andrea P. Krumhardt
1982, Open-File Report 82-356
This report presents all data on arsenic, nitrate, iron, and hardness in well water in the Chena Hot Springs Road, Steele Creek Road, and Gilmore Trail area of Fairbanks, Alaska, collected through October 1981. Concentrations range as follows: arsenic - 0 to 5,100 micrograms per liter; nitrate - 0 to...
Potentiometric-surface map of water in the Lakota Formation and equivalent units in the northern Great Plains area of Montana
Gary Wayne Levings
1982, Open-File Report 82-563
The potentiometric surface of water in the lower Cretaceous Lakota Formation and equivalent units (Cut Bank Sandstone Member , Sunburst Sandstone Member, and Moulton Member of Kootenai formation; Third Cat Creek sandstone of Kootenai Formation; Pryor Conglomerate Member of Kootenai Formation) is shown on a base at a scale of...
Annual Nutrient Loadings, Primary Productivity, and Trophic State of Lake Koocanusa, Montana and British Columbia, 1972-80
Paul F. Woods
1982, Professional Paper 1283
Limnological data collected at Lake Koocanusa were used to investigate the relationship of nutrient loadings, primary productivity, and trophic state of the reservoir during 1972-80. The reservoir, on the Kootenai River, was impounded by Libby Dam on March 21, 1972. Manipulation of the 7.16-cubic-kilometer reservoir for flood control, its primary...
Position of the saltwater-freshwater interface in the upper part of the Floridan Aquifer, southwest Florida, 1979
K.W. Causseaux, J. D. Fretwell
1982, Open-File Report 82-90
Ground-water withdrawals in southwest Florida are increasing because of urban growth, industrial expansion and increased agricultural irrigation. As a result, the potentiometric surface of the Floridian aquifer has been lowered in some areas, allowing seawater to encroach into the aquifer and threaten the freshwater resources of the area. Effective management...
Potentiometric surface of the Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, September 1982
George R. Schiner, Eugene C. Hayes
1982, Open-File Report 83-30
This map presents the potentiometric surface of the Floridan aquifer in the St. Johns River Water Management District and vicinity for September 1982. The Floridan aquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1,000 wells and on several springs. The potentiometric...
Availability of water from aquifers in upstate New York
Irwin H. Kantrowitz, Deborah S. Snavely
1982, Open-File Report 82-437
Two maps give the locations and estimated yields of unconsolidated and bedrock aquifers of upstate New York, excluding Long Island. The map of surficial deposits give estimates of well yield, aquifer yield, and specific capacity; the map of bedrock units gives the same information and also delineates areas in which...
