Download or read book Depth to Bedrock Evaluation Bedrock Structural Analysis and Groundwater Assessment for Southern Door County Wisconsin written by Patrick A. Brodhagen and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Door County, Wisconsin, is a region suffering from significant groundwater contamination issues due to its vulnerable karst geology and existing anthropogenic land use activities. Current reasoning suggests implementing land use regulations defined by depth-to-bedrock conditions will be an effective tool for reducing groundwater quality impacts. The primary purpose of this project was to create an updated depth-to-bedrock map and bedrock surface elevation map for southern Door County. Additional products included in this research are an average water table elevation map, bedrock structural analysis maps, fracture trace maps, and field verification maps demonstrating the compatibility of direct (push probe, well construction reports, etc.) and indirect (geophysical) depth-to-bedrock mapping methods. Furthermore, this thesis attempted to incorporate much of the research done on the geology of the Niagara Escarpment and vulnerability of the Silurian dolomite aquifer from the era of early European settlement to the present day. Many aspects of the Silurian dolomite have already been thoroughly studied; however, data sources and key information from these projects still remain disjointed and need to be interwoven into a single comprehensible document. Numerous chapters have been written on the subject, but no one has compiled the metaphorical (and literal) book yet. This thesis aims to merge the concerns of vulnerable karst geology, anthropogenic land use, and groundwater quality protection and is anticipated to be a guiding document for researchers in other regions of the world addressing similar concerns.
Download or read book Depth to bedrock Map Analysis and Preliminary Deep Aquifer Assessment of Kewaunee County Wisconsin written by Abby W. Shea and published by . This book was released on 2020 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Silurian dolomite aquifer in northeastern Wisconsin has significant anthropogenic contamination. This upper aquifer is karsted in the study area, which, along with thin overlying unconsolidated sediments, contributes to water quality concerns, including viruses, excess nitrates, bacteria, and “brown water” incidents. Some wells in the northwestern portion of the county utilize the deeper, confined Cambrian-Ordovician sandstone aquifer, which is less susceptible to surface contamination. This aquifer has been increasingly utilized in parts of nearby counties for the past 30 years, however little is known about the groundwater chemistry of the aquifer in these areas. This study of 17 wells provides the first water quality analysis of the sandstone aquifer and its suitability to be used as an alternative water supply. The three primary objectives of this study, in order to overall improve our understanding of groundwater resources in and near Kewaunee County, were to analyze the usefulness of depth-to-bedrock maps, determine statistically significant predictors of depth-to bedrock map using soil properties, and to conduct a preliminary assessment of the groundwater quality of the deep, confined sandstone aquifer present in northeastern Wisconsin. The depth-to-bedrock map produced by Luczaj, Houghton and Shea (2019) (hereafter referred to as Luczaj et al. (2019)) yielded significant differences from historic maps. Statistical analyses showed many strong relationships, but also showed that the soil properties of interest cannot be used alone to definitively predict depth-to-bedrock. Piper plots of the confined sandstone aquifer show that the groundwater is of no dominant type, as cations exist in relatively equal proportions, as do anions, although some samples could be classified as sulfate type. Many samples exceeded various health standards, including strontium and radium. Despite various exceedances, the results reveal that the confined sandstone aquifer is a viable source of potable water in the study area along with a variety of treatment methods.

Download or read book Alternatives for Managing the Nation s Complex Contaminated Groundwater Sites written by National Research Council and published by National Academies Press. This book was released on 2013-02-27 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the United States, thousands of hazardous waste sites are contaminated with chemicals that prevent the underlying groundwater from meeting drinking water standards. These include Superfund sites and other facilities that handle and dispose of hazardous waste, active and inactive dry cleaners, and leaking underground storage tanks; many are at federal facilities such as military installations. While many sites have been closed over the past 30 years through cleanup programs run by the U.S. Department of Defense, the U.S. EPA, and other state and federal agencies, the remaining caseload is much more difficult to address because the nature of the contamination and subsurface conditions make it difficult to achieve drinking water standards in the affected groundwater. Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites estimates that at least 126,000 sites across the U.S. still have contaminated groundwater, and their closure is expected to cost at least $110 billion to $127 billion. About 10 percent of these sites are considered "complex," meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations. At sites where contaminant concentrations have plateaued at levels above cleanup goals despite active efforts, the report recommends evaluating whether the sites should transition to long-term management, where risks would be monitored and harmful exposures prevented, but at reduced costs.
Download or read book Regional Cooperation for Water Quality Improvement in Southwestern Pennsylvania written by National Research Council and published by National Academies Press. This book was released on 2005-04-04 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The city of Pittsburgh and surrounding area of southwestern Pennsylvania face complex water quality problems, due in large part to aging wastewater infrastructures that cannot handle sewer overflows and stormwater runoff, especially during wet weather. Other problems such as acid mine drainage are a legacy of the region's past coal mining, heavy industry, and manufacturing economy. Currently, water planning and management in southwestern Pennsylvania is highly fragmented; federal and state governments, 11 counties, hundreds of municipalities, and other entities all play roles, but with little coordination or cooperation. The report finds that a comprehensive, watershed-based approach is needed to effectively meet water quality standards throughout the region in the most cost-effective manner. The report outlines both technical and institutional alternatives to consider in the development and implementation of such an approach.

Download or read book Isotope Methods for Dating Old Groundwater written by International Atomic Energy Agency and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guidebook provides theoretical and practical information for using a variety of isotope tracers for dating old groundwater, i.e. water stored in geological formations for periods ranging from about 1000 to one million years. Theoretical underpinnings of the methods and guidelines for their use in different hydrogeological environments are described. The guidebook also presents a number of case studies providing insight into how various isotopes have been used in aquifers around the world. The methods, findings and conclusions presented in this publication will enable students and practicing groundwater scientists to evaluate the use of isotope dating tools for specific issues related to the assessment and management of groundwater resources. In addition, the guidebook will be of use to the scientific community interested in issues related to radioactive waste disposal in geological repositories.
