Availability and Chemical Quality of Water From Surficial Aquifers in Southwest Minnesota

Description: From introduction: The objectives of the study were to (1) determine the areal extent, thickness, and water-yielding capability of aquifers in the surficial deposits, (2) estimate the amount of water in storage in the aquifers, (3) determine the chemical quality of water in the aquifers and, (4) establish observation wells to monitor the effects of ground-water development on water levels and storage in the aquifers.

Buried Aquifers in the Brooten-Belgrade and Lake Emily Areas, West-Central Minnesota -- Factors Related to Developing Water for Irrigation

Description: Purpose and scope: The purpose of this report is to determine, as far as possible, the occurrence of buried aquifers and to describe their hydrologic characteristics and water-yielding capability. The evaluation is based mainly on 44 test holes drilled specifically for this investigation. These test holes are too widely spaced to correlate individual aquifers. Such correlation must await more detailed closely spaced test drilling. Forty-two test holes were drilled in the Brooten-Belgrade area; hence the mapping is restricted to this part. Two test holes were drilled in the Lake Emily area, allowing only one geologic section to be presented. PIan-view mapping would require considerable additional test drilling.

Change Houses in the Lake Superior Region

Description: Technical paper issued by the Bureau of Mines over change and wash houses in the Lake Superior area. As stated in the introduction, "this paper, with a few exceptions, presents data acquired in a survey, made by the author, of change houses in the Lake Superior region. All buildings, equipment, and practices were studied with regard for the health and welfare of the miner" (p. 1). This paper includes tables, photographs, and illustrations.

City Smoke Ordinances and Smoke Abatement

Description: From Introduction: "In connection with the fuel investigations conducted by the Bureau of Mines much information has been accumulated as to the smoke abatement activities in various cities. The essential features of the information are presented in this report, which, it is believed, will be of public interest and benefit, especially to those communities that are just beginning organized effort to abate unnecessary smoke."

Design of a Groundwater Sampling Network for Minnesota

Description: From introduction: This folio was compiled to facilitate the use of groundwater as a sampling medium to aid in exploration for hitherto undiscovered deposits of uranium in the subsurface rocks of Minnesota. The report consists of the following sheets of the hydrogeologic map of Minnesota: 1) map of bedrock hydrogeology, 2) generalized cross sections of the hydrogeologic map of Minnesota, showing both Quaternary deposits and bedrock, 3) map of waterwells that penetrate Precambrian rocks in Minnesota. A list of these wells, showing locations, names of owners, type of Precambrian aquifers penetrated, lithologic material of the aquifers, and well depths is provided in the appendix to this report.

Digital Models of a Glacial Outwash Aquifer in the Pearl-Sallie Lakes Area, West-Central Minnesota

Description: From purpose and scope: The purpose of this investigation is to 1) study the hydrologic system in a glaciated terrain typified by numerous lakes, with particular focus on the effects of lake-ground-water interchange, 2) simulate the natural system by using two digital modeling methods--areal (map view) and vertical section, and 3) evaluate the utility of the models and determine the kinds and amount of basic data needed to obtain reasonable simulations.

The Eruptive and Sedimentary Rocks on Pigeon Point, Minnesota, and Their Contact Phenomena

Description: From preface: The preparation of this paper is due to the fact that the eruptive rocks occurring on Pigeon point, Minnesota, may be taken as types of similar eruptives found so widely spread over the Huronian and Keweenawan areas surrounding Lake Superior, and to the peculiar nature of the alteration these have superinduced in the fragmental rocks through which they have broken.

Fortran Computer Programs to Plot and Process Aquifer Pressure and Temperature Data

Description: From introduction: In this report, two programs have been developed for use in managing data derived from an aquifer thermal-energy storage (ATES) project being done by the University of Minnesota. Data are generated from temperature and pressure measuring devices that are read automatically by a datalogger. Up to 100 channels can be scanned every 10 seconds and recorded on magnetic tape or printed as paper output. Time period of up to several years of data may be represented on a single tape.

Ground-Water Appraisal of the Pineland Sands Area, Central Minnesota

Description: Purpose and scope: The major purpose of this study is to evaluate the ground-water resources in the Pineland Sands area and their potential for development. The study focuses mainly on the surficial aquifer, the single most readily available source of ground water. Primary objectives of the study are (1) map the areal extent and thickness of the surficial aquifer, (2) determine its ability to transmit water to wells and define the availability of the water, (3) describe the chemical quality of the water, and (4) model the aquifer and simulate probable effects of future development. By evaluating the adequacy of the surficial aquifer, this study should aid in the proper development and management of water resources in the Pineland Sands area.

Ground Water for Irrigation in the Viking Basin, West-Central Minnesota

Description: Abstract: The Viking Basin consists of six glacial outwash areas in Douglas, Ottertail, and Todd Counties, west-central Minnesota. Total area is 340 square miles (880 square kilometers). Soils are sandy and excessively well-drained. Crops grown on the outwash would benefit from supplemental irrigation. Irrigation supplies can be obtained from wells in the surface outwash aquifer in significant parts of the large outwash areas near Carlos and Parkers Prairie and the small outwash area near Clotho. Irrigation supplies are unlikely in the outwash areas near Alexandria, Urbank, and Rose City. Major use of ground water for irrigation may lower ground-water levels sufficiently to affect lake and marsh levels and streamflow out of the irrigation areas. Water from the outwash is of excellent chemical quality for irrigation.

Ground-Water-Use Trends in the Twin Cities Metropolitan Area, Minnesota, 1880-1980

Description: From purpose and scope: The purpose of this report is to describe trends in ground-water use in the Twin Cities metropolitan area, Minnesota, from 1880 to 1980. Water-use trends are discussed in terms of use category, volume of water used over time, aquifer, and well location.

Hydrogeologic and Water-Quality Characteristics of the Ironton-Galesville Aquifer, Southeast Minnesota

Description: Introduction: The U.S. Geological Survey began a study in 1980 of the quality of water in the principal aquifers of Minnesota. The U.S. Environmental Protection Agency funded the study as part of the Underground Injection Control Program, which deals with disposal of liquid wastes beneath land surface. The initial report designated 14 aquifers in the State and provided general information about their geologic, hydrologic, and water-quality characteristics (Adolphson and others, 1981). This report, one in a series that describes individual aquifers in more detail, concerns the Ironton-Galesville aquifer.

Hydrogeologic and Water-Quality Characteristics of the Mount Simon-Hinckley Aquifer, Southeast Minnesota

Description: From abstract: This report is one of a series on the hydrogeology and water quality of the 14 principal aquifers in Minnesota prepared by the U.S. Geological Survey. The U.S. Environmental Protection Agency requested these studies because of the need for information to develop its Underground Injection Control Program.
