Hydrogeology of the Buffalo Aquifer, Clay and Wilkin Counties, West-Central Minnesota

From introduction: The objective of this study are to (1) determine the areal extent and thickness of the Buffalo aquifer and the general occurrence of deeply buried aquifers, (2) determine the potential for development of water supplies from wells in the Buffalo aquifer, (3) investigate and discuss annual recharge to the Buffalo aquifer and the potential for artificially recharging the aquifer, (4) determine the chemical quality of water in the aquifer and in area streams, (5) establish a network of observation wells for monitoring water levels and water quality in the aquifer, (6) determine the relationship between the aquifer and the adjacent streams, and (7) update the information on the flow characteristics of the streams. The main focus of this study is on water in the Buffalo aquifer and on flow characteristics of streams.

Assessment of Water Quality in Streams Draining Coal-Producing Areas in Ohio (open access)

Assessment of Water Quality in Streams Draining Coal-Producing Areas in Ohio

From introduction: In 1975 a project was begun to provide information on several aspects of coal hydrology in Ohio. The first phase was a reconnaissance of water-quality conditions in coal-mining regions. Phase one had two primary objectives; to document the occurrence of certain inorganic and organic constituents in waters of the coal-mining regions and to determine if the concentrations of those constituents were related to coal mining. The second phase of the project was a more detailed study of four basins sampled during the first phase.

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

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

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.

Water Use in Ohio 1975

From introduction: This report summarizes estimates of Ohio water use for 1975. These figures are revisions of data which were compiled by the U.S. Geological Survey in the Circular, "Estimated Water Use in the United States, 1975" (Murray and Reeves, 1976). In that circular, water-use figures were aggregated for the state of Ohio as a whole, and for the U.S. Water Resources Council's Great Lakes and Ohio River hydrologic regions.

Water Quality of Alignment, Farquar, and Long Lakes in Apple Valley, Minnesota (open access)

Water Quality of Alignment, Farquar, and Long Lakes in Apple Valley, Minnesota

Abstract: Alimagnet, Farquar, and Long Lakes, in Apple Valley, Minnesota, were sampled from 1973-79 to determine their physical and chemical characteristics. A storm-sewer inlet to Alimagnet Lake was also sampled during two storms in 1978. The 1976-77 drought caused a more noticeable effect on the quality of the lakes than any other factor. Chloride concentrations were 10 to 15 milligrams per liter before the drought, but increased 2 to 4 times during the drought. Dissolved solids reacted similarly . Dissolved oxygen and pH were governed mainly by biological activity. In February 1977, dissolved-oxygen concentration was less than 0.5 milligrams per liter in the three lakes. Ratios between mean total nitrogen and mean total phosphorus ranged from 22:1 to 26:1. Tropic-state indices indicate that the lakes are eutrophic. Blue-green algae dominated the phytoplankton populations. Storms sampled at a storm-sewer inlet to Alimagnet Lake showed higher concentrations pf chromium, copper, nickel, and zinc than of lead, arsenic, cadmium, and mercury. Total phosphorus for the September 1978 storm had a concentration of 1.7 milligrams per liter, which means that approximately 29 pounds entered the lake during the 5.5-hour sampling period.

Effects of Land Use on Surface-Water Quality in the East Everglades, Dade County, Florida (open access)

Effects of Land Use on Surface-Water Quality in the East Everglades, Dade County, Florida

From purpose and scope: Concern by officials of both Everglades National Park and Dade County about the effects of development of land in the East Everglades for various uses created the need for additional information on the hydrology of this wetland. The hydrology of wetlands is also a major thrust of the U.S. Geological Survey. Because of this mutual interest, the U.S. Geological Survey and Dade County have cooperated in a study of one element of wetland hydrology--the effects that certain land uses have on the surface-water quality (Metropolitan Dade County Planning Department, 1978, p. 49-52).
