Figure 1. Location of Fairbanks, Alaska and Fort Wainwright study area. are a total of 121 environmental reports. Following the alphabetical listing is a numerical listing of reports, included for ease of cross-referencing reports for locations shown on plate 1. Environmental contractor reports are filed by report number and available from the Fairbanks office of the U.S. Geological Survey, 800 Yukon Drive, Fairbanks, Alaska 99115. U.S. Geological Survey Reports and Data Bases The USGS has been conducting hydrologic investigations in the interior of Alaska since the early 1900s. The USGS is continuing to collect groundwater and surface-water data at monthly intervals for use in its regional investigations and for support of site-specific environmental studies (Claar and Lilly, 1995; Kriegler and Lilly, 1995; see USGS reports listing). Data are also collected at more frequent time intervals as needed. Report series containing information useful for environmental investigations include annual data reports of hydrologic information, geologic and hydro-University of Alaska Water Resources Center Reports The University of Alaska's WRC has also investigated many hydrologic processes and areas in interior Alaska. Results of these investigations are reported in university theses, report series, and outside journal and professional publications. This document includes a section listing reports on the activities of the WRC in the Fairbanks area or concerning arctic hydrologic processes in general; these reports are available at the WRC. The WRC was previously named the Institute of Water Resources (IWR), thus the WRC Series reports are continued with the same numbering scheme as the IWR Series reports. Appendixes The American Society for Testing and Materials (ASTM) is currently under an accelerated standards and methods development process relating to groundwater investigations. The process has been jointly supported by the USGS, U.S. Department of Defense, U.S. Environmental Protection Agency, and industry representatives. Appendix 1 presents selected standards related to environmental investigations and guidelines for producing environmental and geotechnical reports. This information is included as supplemental reference material on procedures and methods for groundwater investigations. These standards are available from the ASTM, or may be found in Volumes 4.08 and 4.09 of the Annual Book of ASTM Standards. Appendix 2 consists of part of a section from the National Water Information System User's Manual (Luckey and Rogers, 1989; see USGS reports listing). A listing of the fields and field codes for GWSI is included in the appendix, with information on how to formulate the local numbering system used by the USGS in Alaska ORGANIZATION OF THIS REPORT 3 o
