Reconnaissance for Determining Effects of Land Use and Surficial Geology on Concentrations of Selected Elements on Streambed Materials from the Coal-Mining Region, Southwestern Indiana, October 1979 to March 1980

Description: From introduction: The objectives of the streambed-materials rials reconnaissance were to: (1) provide baseline concentrations of selected elements sorbed on streambed materials and (2) determine the effect of land use and surficial geology on the concentration of selected elements on streambed materials from southwestern Indiana.

Effects of Coal Fly-Ash Disposal on Water Quality in and Around the Indiana Dunes National Lakeshore, Indiana

Description: Abstract: Dissolved constituents in seepage from fly-ash settling ponds bordering part of the Indiana Dunes National Lakeshore (the Lakeshore) have increased trace elements, and gross alpha and gross beta radioactivity in the ground water and surface water downgradient from the settling ponds. Data suggest that concentrations of some dissolved trace elements may be greater beneath interdunal pond 2 than in the pond. The soil system downgradient from the settling ponds seems to have affected the concentrations of dissolved ions in the settling-ponds than in the ponds. Where organic material was present downgradient from the settling ponds, concentrations of arsenic, fluoride, molybdenum, potassium, sulfate, and strontium were greater in the ground water than in the ponds. In contrast, the concentrations of cadmium, copper, nickel, aluminum, cobalt, lead, and zinc were less.

A Technique for Estimating the Time of Travel of Water in Indiana streams

Description: Abstract: Estimates of the travel time of waterborne particles in streams is important for pollution studies and in the event of spills of contaminants. This report provides data for the 16 Indiana streams on which time-of-travel information has been obtained and a means for estimating the velocity of any naturally flowing stream in Indiana with a drainage area of 80 square miles (210 square kilometers) or more. Measured velocity rates compiled from the time-of-travel data collected in Indiana are related to 25, 50, 100, and 200 percent of the average discharge of streams shown in this report. Velocities at these discharges are significantly related to their respective watershed characteristics (average discharge and slope).Generalized relations of the velocities as functions of the streams' watershed characteristics are developed as multivariate regression equations using the data from each of the measured streams.

Availability of Ground Water near Carmel, Hamilton County, Indiana

Description: Abstract: Flow in the unconsolidated glacial deposits near the city of Carmel in central Indiana was simulated by a digital-computer model in a study of hydraulic characteristics of the deposits. The study shows that 21 • 3 million gallons per day (933 liters per second) of additional water could be withdrawn from the aquifer for an indefinite period of time. This pumpage is approximately 5 million gallons per day (219 liters per second) above the projected water needs of Carmel for 1990. Saturated thickness, transmissivity, and storage coefficient of the outwash aquifer along the White River east of Carmel were determined, using available data supplemented by test drilling . The saturated thickness of the aquifer ranges from 10 to 110 feet 0 to 34 meters ); transmissivity ranges from 1,000 feet squared per day (93 meters squared per day) to 24 ,000 feet squared per day (2 ,230 meters squared per day); and the average storage coefficient is 0.11.

Indiana Stream-Temperature Characteristics

Description: From introduction: The purpose of this study was twofold: (1) to compile Indiana stream-temperature data and (2) to develop an equation for estimating water-temperature characteristics, as represented by harmonic coefficients, at locations where historical temperature data may no be available.

Hydraulic Characteristics and Water-Supply Potential of the May 1975 Aquifers in the Vicinity of the Wastewater Treatment Plant, South Bend, Indiana

Description: Abstract: An intensive study was made of a 24-square mile (62-square kilometer) area surrounding the South Bend wastewater treatment plant to document the effects of dewatering about 40 feet (12 meter) of the 130-feet (40-meter) thick aquifer during construction at the plant, define the hydrologic system in order to allow development of a predictive model and select and evaluate one possible water-supply development plan as a model demonstration. Model-simulated water levels agree very well with those observed, both before and during dewatering. Model results indicate that the hydrologic system can sustain withdrawal of 28 million gallons per day (106,300 cubic meter per day) indefinitely with little effect on ground-water levels. The quantity that would be diverted from the St. Joseph River is less than 10 percent of the estimated minimum daily flow.

Plan of Study for the Northern Midwest Regional Aquifer-System Analysis

Description: From abstract: Sedimentary rocks of Cambrian and Ordovician age form a major aquifer system in most of Wisconsin and Iowa, northern Illinois, northwestern Indiana, southeastern Minnesota, and northern Missouri. Many metropolitan areas depend on the aquifer for all or part of their water supplies. Declines in potentiometric head have been large in the most heavily pumped areas, most notably Chicago, Milwaukee-Waukesha, Minneapolis-St. Paul, and Des Moines.

Ground-Water Resources of the Glacial Outwash Along the White River, Johnson and Morgan Counties, Indiana

Description: From abstract: A two-dimensional digital model of the ground-water-flow system was constructed to test the conceptual model of the system ad to study the effects of development on ground-water levels and flow in the White River.
