Potentiometric surface of the upper Floridan aquifer, west-central Florida, September 1993
R. A. Mularoni
1994, Open-File Report 94-81
A map of the September 1993 potentiometric surface of the Upper Floridan aquifer in west-central Florida depicts ground-water levels for the annual high water-level period. Water levels measured in September 1993 were generally lower than those reported for September 1992. In 572 wells with paired measurements, the September 1993 level...
Water-quality data for selected North Carolina streams and reservoirs in the Triangle Area Water Supply Monitoring Project, 1988-92
Ronald G. Garrett, John E. Taylor, Terry L. Middleton
1994, Open-File Report 94-379
The Triangle Area Water Supply Monitoring Project was developed to assess regional water-quality characteristics in drinking-water supplies and to provide a basis for determining trends in water quality for the Research Triangle area, which is one of the fastest growing areas in North Carolina. The study area is in the...
Hydrologic data for the Puerco River basin, western New Mexico, October 1, 1991, through September 30, 1992

The effects of uranium mining and a 1979 tailings pond spill, in combination with naturally occurring and potentially hazardous trace elements, have created a concern that surface water and...
Bibliography of selected water-resources information for the Arkansas River basin in Colorado through 1985
John M. Kuzmiak, Hyla H. Strickland
1994, Open-File Report 94-331
The Arkansas River basin composes most of southeastern Colorado, and the numerous population centers and vast areas of agricultural development are located primarily in the semiarid part of the basin east of the Continental Divide. Because effective management and development of water resources in this semiarid area are essential...

Simulation analysis of the ground-water flow system in the Portland Basin, Oregon and Washington
David S. Morgan, William D. McFarland
1994, Open-File Report 94-505
A numerical model of the ground-water flow-system in the Portland Basin, Oregon and Washington, was used to test and refine the conceptual understanding of the flow system and estimate the effects of past and future human-caused changes to the ground-water system. Recharge to the basin in 1987-88 consisted primarily of...
