Test monitoring of prototype injection well, Waiale, Maui, Hawaii

A high-capacity prototype injection well was tested in the isthmus area of Maui, Hawaii. Pumping tests were made on April 14 and 15, 1978, and 10 injection tests were made between May 12 and June 30, 1978. Selected tests were monitored in order to obtain data which could be used to assess the effects of subsurface disposal on the ground water in the basal aquifer. Pumping and injection rates were measured. Basal-water head responses to pumping and injection were observed at the prototype well and at two observation wells located 435 and 6 ,100 feet from the prototype well. Water-quality samples were collected at the prototype well and the nearest observation well prior to testing. Samples of the injection water, as well as samples from the observation wells, were collected prior to and after the final test. The head data and water-quality data are presented in this report.

Techniques for estimating magnitude and frequency of floods for Wisconsin streams

This report provides improved methods for estimating the magnitude and frequency of floods for Wisconsin streams. Proper design of hydraulic structures and adequate flood-plain management depend on this information. Multiple-regression techniques were used to develop equations for estimating flood frequencies at ungaged sites. The State is divided into five areas and has equations developed for each area. These areas are based on areal factors determined from previous studies and physical basin characteristics. Significant characteristics in the equations are soil permeability, drainage area, slope, storage, forest cover, snowfall, precipitation intensity, and mean annual precipitation. Standard errors of estimate for the regression equations ranged from 23 to 38 percent. Annual flood peaks, basin characteristics, and flood-frequency values are presented in this report. Data from 184 gaging stations were used in the regression analysis, of which 20 had rainfall-runoff data collected. Long-term synthetic peaks were generated from the rainfall-runoff data and were weighted with the observed peak data to improve the flood-frequency distributions. A method to estimate flood-frequency values for regulated streams was developed by discharge-drainage area relationships. Graphs for the major regulated streams are presented in the report.

A summary report of the regional geology, environmental geology, OCS resource appraisal, petroleum potential, and operational considerations in the area of proposed lease sale 73, offshore California

This report reviews geological, geophysical and technological data pertinent to proposed Lease Sale 73. Under consideration is the entire continental margin of California that is bounded on the west by the 2500 meter isobath. This area encompasses the whole of the southern California Borderland, the continental shelves of central and northern California, and the upper part of the continental slope from Mexico on the south to Oregon on the north. The area includes both leased and unleased tracts and lies adjacent to highly productive coastal basins of central and northern California . Because the geology of the south and north parts of this large area differ, they are considered separately in this report.

Floods of March 1978, in the Maumee River basin, northeastern Indiana

Floods in the Maumee River basin in northeastern Indiana in March 1978 resulted in heavy damage in Fort Wayne and surrounding areas. Flood damage in Fort Wayne was estimated by the Mayor to be 11 million dollars. Approximately 15 percent of the city was inundated, and 2,400 of its 190,000 residents were forced to leave their homes. The estimate of damage in Adams and Allen Counties by Civil Defense officials was 44 million dollars. The Maumee River at New Haven exceeded the peak stage of record, 21.4 feet, by 2.2 feet. The peak discharge at this stream-gaging station, 22,400 cubic feet per second, was about equal to that of a 75-year flood. Recurrence intervals of peak flows on streams tributary to the Maumee River ranged from 5 to 50 years. Records of peak and daily discharges and some precipitation data are given in this report.

A crustal deformation observatory near the San Andreas Fault in central California (PB3)

This final technical report discusses several objectives and accomplishments of the first years effort of a project titled A Crustal Deformation Observatory Near the San Andreas Fault in Central California. This period saw the conclusion of the Hollister MWDM effort that has produced nearly continuous, high precision, line length measurements for the last 5 years. The establishment of an observatory similar to that used during the Hollister MWDM effort is underway near San Juan Bautista and both high precision vertical and horizontal measurements will commence in the near future. An interim measurement program was begun near Palmdale in Southern California during October 1980 and is continuing at the present time. Extensive electronic modification to the MWDM instrument has also been successfully completed during this reporting period. Each of these efforts will be discussed in more detail in the following sections of this report.

Water-quality data for streams in the southern Yampa River basin, northwestern Colorado

Increases in coal mining in Colorado have raised questions regarding the impact of mining on the quality of surface water. An area where increases have caused particular concern is in northwestern Colorado, in the southern part of the Yampa River basin. In order to identify the changes produced by mining in the area it is necessary first to identify the water chemistry resulting from the geology, climate, and land use. To answer the above questions, a program for the synoptic collection of water-quality data was developed in which a network of sampling sites was established to determine the surface-water chemistry. This study was begun in April 1981. Water-quality samples were collected from sites on all continuously flowing streams in the southern part of the Yampa River basin from the Oak Creek drainage near Steamboat Springs on the east to the surface-water gaging station on the Yampa River near Maybell on the west. Each water-quality site was sampled repetitively as changes occurred in discharge and specific conductance. Water-quality data from surface-water gaging stations in the area for water years 1976 to 1981 are included in the report.

Plan of study for the regional aquifer systems analysis of the Michigan Basin

Quaternary glacial deposits and Pennsylvanian and Mississippian sandstones, -the Saginaw Formation and Marshall Sandstone- are the major aquifers in the Michigan basin. These aquifers supply approximately 188 million gal/day to municipalities in the 29 ,000 sq mi study area. The most significant problems related to groundwater supplies are the identification of potable sources of groundwater in large quantities and the migration of saline groundwater toward pumping centers. Saline water underlies the entire lower Peninsula of Michigan at indeterminate depth in the deeper parts of the Saginaw Formation and Marshall Sandstone in the center of the Michigan basin. In places, saline water is present in glacial deposits. Overdraft has resulted in severe drawdown in the Lansing area and the abandonment of wells near Flint because of saline water encroachment. Increased demand on the groundwater resources of the study area are expected to cause further problems. In 1985, the U.S. Geological Survey began a 5-yr study to define the geohydrologic framework, describe the geochemistry of groundwater in the glacial and bedrock aquifers, and analyze regional groundwater flow patterns. The scope, plan of study, organization and work elements are described in this report.

Hydrologic and chemical data from an experiment to examine temporal variability in water samples from screened wells on Cape Cod, Massachusetts

An experiment was designed to evaluate the changing chemical composition of the water pumped from a well screened in a physically and chemically heterogenous aquifer. Well F453-63, at the U.S. Geological Survey Toxic-Substances Hydrology research site located on Cape Cod, Massachusetts, was selected because it was known that the screen penetrated both the oxic and anoxic zones of the sewage plume from the Otis Air Base sewage-disposal sand beds. The experiment was conducted on August 12, 1992. Well F453-63 was sampled over time as it was pumped continuously, and three multilevel samplers were used to document the vertical distribution of selected chemicals in the ground water in the immediate vicinity of the well. All water samples obtained during the experiment were analyzed in the field for specific conductance and pH. The samples were subsequently analyzed for concentrations of ferrous iron (Fe+2), boron, calcium, chloride, iron (Fe total), phosphorus, potassium, magnesium, manganese, sodium, zinc, and nitrogen species, including nitrous oxide, ammonium, nitrite and nitrate. The results of these chemical analyses along with appropriate physical measurements of the site and aquifer material are documented in this data report.
