Ground-water and surface-water elevations in the Fairbanks International Airport area, Alaska, 1990-96, and selected geohydrologic report references
David V. Claar, Michael R. Lilly
1997, Open-File Report 97-597
Ground-water and surface-water elevation data were collected at 61 sites from 1990 to 1996 by the U.S. Geological Survey in cooperation with the Alaska Department of Transportation and Public Facilities, Fairbanks International Airport. Water-surface elevations were measured in 41 ground-water observation wells and at 20 surface-water sites to help characterize...
Studies of the San Francisco Bay, California, estuarine ecosystem regional monitoring program results, 1996
Jelriza I. Baylosis, Jody L. Edmunds, Brian E. Cole, James E. Cloern
1997, Open-File Report 97-598
As part of a regional monitoring program, water samples were collected in the San Francisco Bay estuary during 21 cruises from January through December 1996. Conductivity, temperature, light attenuation, turbidity, oxygen, and in-vivo chlorophyll fluorescence were measured longitudinally and vertically in the main channel of the estuary from south of...
Snow and ice volume on Mount Spurr Volcano, Alaska, 1981
Rod S. March, Lawrence R. Mayo, Dennis C. Trabant
1997, Water-Resources Investigations Report 97-4142
Mount Spurr (3,374 meters altitude) is an active volcano 130 kilometers west of Anchorage, Alaska, with an extensive covering of seasonal and perennial snow, and glaciers. Knowledge of the volume and distribution of snow and ice on a volcano aids in assessing hydrologic hazards such as floods, mudflows, and debris...
Spring contributions to water quantity and nitrate loads in the Suwannee River during base flow in July 1995
J. R. Pittman, H. H. Hatzell, E. T. Oaksford
1997, Water-Resources Investigations Report 97-4152
The Suwannee River flows through an area of north-central Florida where ground water has elevated nitrate concentrations. A study was conducted to determine how springs and other ground-water inflow affect the quantity and quality of water in the Suwannee River. The study was done on a 33-mile (mi) reach of...
Nitrate in ground water and stream base flow in the lower Susquehanna River Basin, Pennsylvania and Maryland
Bruce D. Lindsey, Connie A. Loper, Robert A. Hainly
1997, Water-Resources Investigations Report 97-4146
High concentrations of nitrate in both ground and surface water have been identified as a significant water-quality issue in the Lower Susquehanna River Basin. This report uses data collected by the National Water Quality Assessment (NAWQA) Program in the basin and compares nitrate concentrations found in ground water and surface...
Recharge areas and quality of ground water for the Glen Canyon and valley-fill aquifers, Spanish Valley area, Grand and San Juan counties, Utah
Judy I. Steiger, David D. Susong
1997, Water-Resources Investigations Report 97-4206
The Spanish Valley area in southeastern Utah (fig. 1) is experiencing a rapid increase in development of residential and business property. In this report, the Spanish Valley area refers to the geographic area shown in figures 1, 3, and 4. This area includes Moab Valley, Spanish Valley, and the mesa...
Results of soil, ground-water, surface-water, and streambed-sediment sampling at Air Force Plane 85, Columbus, Ohio, 1996
J. M. Parnell
1997, Open-File Report 97-641
The U.S. Geological Survey (USGS), in cooperation with Aeronautical Systems Center, Environmental Management Directorate, Restoration Division, prepared the Surface- and Ground- Water Monitoring Work Plan for Air Force Plant 85 (AFP 85 or Plant), Columbus, Ohio, under the Air Force Installation Restoration Program to characterize any ground-water, surface-water, and soil...
Water-quality assessment of the Rio Grande Valley, Colorado, New Mexico, and Texas; water-quality data for water-column, suspended-sediment, and bed-material samples collected at selected surface-water sites in the upper Rio Grande Basin, June and September 1994
L.K. Miller, R.L. Moquino, B.A. Hill
1997, Open-File Report 97-644
As part of the Rio Grande Valley National Water-Quality Assessment Program, samples were collected at 34 sites in the upper Rio Grande Basin in Colorado and New Mexico during June and September 1994. The focus of the sampling was on trace-element concentrations in the water column, suspended sediment, and...
Nitrate (NO2+NO3–N) in ground water of the Upper Snake River basin, Idaho and western Wyoming, 1991–95
Michael G. Rupert
1997, Water-Resources Investigations Report 97-4174
Factors related to contamination of ground water by dissolved nitrite plus nitrate as nitrogen (NO2+NO3-N) in parts of the upper Snake River Basin were evaluated at regional and local scales. Regional-scale relations between NO2+NO3-N concentrations and depth to first-encountered ground water, land use, precipitation, and soils were evaluated using a...
