Potential changes to climate and precipitation patterns from anthropogenic influences like global climate change could have an impact on Michigan’s groundwater resources. Indirectly this could have an effect on Michigan’s surface waters as well, since groundwater and surface waters are intimately linked to form one system. This investigation utilized stable isotopes of oxygen and hydrogen found in precipitation, groundwater and surface waters to better understand the contribution of different types of precipitation to recharge of a shallow aquifer in Manistee National Forest, MI. The study also examines the contribution of this shallow groundwater to streamflow in the nearby White River. When combined with various physical and chemical hydrologic approaches, the dynamics of precipitation, groundwater flow and groundwater discharge into the stream become clearer. Samples from the different waters were collected from February 2015 to January 2016. During sampling groundwater head, stream discharge and other parameters were measured. These data provide valuable insight that will help the U.S. Forest Service better manage this natural resource.

The purpose of the project was to demonstrate the value of age-dating and isotopic tracers in characterizing the flow dynamics and water quality changes in a complex groundwater domain that includes high capacity municipal pumping wells, a geologic fault, and artificial recharge facilities with deep lake-like recharge ponds. Characterizing water quality changes during recharge and transport in groundwater was also an objective of this investigation. Below (west of) the Hayward Fault (BHF), water ages correlated well with aquifer layer sequence. BHF tracers did not reach the BHF wellfield within the time frame of the experiment. Above (east of) the fault, (AHF) tracers reached the targeted wellfield in only 60 days, indicating substantial heterogeneity and a fast travel time along preferential pathways compared to the average travel time of 2+ years indicated by age-dating and more classical estimating methods. A reconnaissance of water quality, conducted concurrently with the tracer studies, suggested certain water quality improvements occurring in either the pond sediment or the near-pond aquifer media. Variations in groundwater age depended on location and depth. A survey of natural isotopes indicated mixing of young and older water in wells, increasing age with depth of aquifer layer, and possible dissolution of carbonate minerals. AHF tracer experiments, along with other analysis, suggested that tracers probably percolated preferentially at shallow depths in the pond near the shoreline. Much of the tracer remained in deep pond water over time, increasing residence time in down-gradient wells. The tracer studies provided evidence of preferential pathways and heterogeneity in the AHF aquifer and a fast minimum travel time to the AHF wellfield. The tracer added to BHF ponds was detected in just two monitoring wells, but not at the BHF wellfield over the 10-month period. An AHF tracer from a small pond spanning the fault did, however, appear at the BHF wellfield. BHF pond water flows mainly to distal portions of the groundwater basin, or reaches the wellfield over a slow, circuitous route.

This publication discusses several theoretical aspects important to the understanding, planning and monitoring of AR and ASR schemes and presents a selected number of examples illustrating the usefulness of isotopes and other tracers. One section presents the list of available isotope tracers, indicating the type of information that can be obtained from each. The case studies presented in this publication illustrate the use of these tools in the different stages of AR and ASR schemes.

This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.

Investigating Groundwater provides an integrated approach to the challenges associated with locating groundwater. Uniquely, the book provides a review of the wide range of techniques that can be deployed to investigate this important resource. Many of the practical examples given are based upon Australian experience but the methods have worldwide applicability. The book is published in colour and includes many original diagrams and photographs. Particular effort has been made to provide consistent terminology and SI units are used throughout the text Investigating Groundwater starts with an introduction to the historical significance of groundwater and gives an account of climate change. A description of the occurrence of groundwater in different rock types is then provided. A detailed account of surface water techniques is then followed by an account of the interconnections between surface water and groundwater. Four chapters describing groundwater hydraulics are then followed by four chapters describing the latest geophysical techniques. Once the best location of a borehole is determined using these techniques; chapters then describe appropriate drilling methods to use; provide a wide ranging review of geophysical logging, hydrochemical and isotopic techniques, before concluding with a detailed description of groundwater flow to a well. Written for a worldwide audience of degree level geology/engineering practitioners, academics and students involved in groundwater resource investigation methods; Investigating Groundwater is essential reading for those involved in groundwater research. Key Features: Presents the theoretical background and a detailed description of the techniques used in the investigation of groundwater. Describes the general occurrence of groundwater in different rock types; surface water hydrology and interconnected surface and groundwater systems. Provides detailed descriptions of geophysical techniques (seismic, electrical, gravity and heat) and an account of available geophysical logging methods. Reviews hydrochemical and isotope methods, followed by an account of drilling techniques. Gives a detailed account of radial flow to a well, including appropriate modelling and pump-testing techniques and a consideration of non-linear flow. Of interest to anyone involved in the development of groundwater resources, either for domestic supply, for agriculture or for mining.

In recent years, the focus in groundwater studies has expanded to also include groundwater contamination and remediation studies as a part of resource evaluations. While there are other books on the subject, Field Hydrogeology-A Guide for Site Investigations and Report Preparation provides the first integrated presentation of the American Society of Testing Materials (ASTM) standards, US Geological Survey (USGS), and US Environmental Protection Agency (EPA) field techniques. It also includes access to a Web site that contains software for designing aquifer tests and aquifer-recharge experiments. Written by an author with more than 40 years of experience in hydrology and geology, this reference treats the subject from a field standpoint. Useful as a field guide and a textbook, it contains standard methods for planning and undertaking hydrogeologic investigations. It incorporates case studies, contains a glossary of field-hydrogeology technical terms, and provides a detailed list of ASTM standards and key hydrologic Web sites. The guide is based on ASTM standards, EPA, and US Department of Interior (DOI) field technical manuals. The text covers hydrogeologic fundamentals, conceptual models, planning an investigation, surface investigations, subsurface investigations, field inventory, stream flow measurements, water quality measurements, and report preparation. It includes more recent groundwater evaluation techniques such as tracing and isotope techniques. Field Hydrogeology will allow students and seasoned professionals to have a vast array of clearly written descriptive materials and an extensive source of references available at their fingertips. About the Author: John E. Moore, Ph.D., is a hydrogeologist at the USEPA Region 8 in Denver, Colorado.
