WRIR 96-4233-Guidelines and Standard Procedures for Studies of Ground-Water Quality: Selection and Installation of Wells, and Supporting Documentation Guidelines and Standard Procedures for Studies of Ground-Water Quality: Selection and Installation of Wells, and Supporting Documentation Water-Resources Investigations Report 96-4233 By Wayne W. Lapham, Franceska D. Wilde, and Michael T. Koterba An html version of the abstract is shown below. This report is available as a 2.1 MB pdf file: WRIR 96-4233 Abstract This is the first of a two-part report to document guidelines and standard procedures of the U.S. Geological Survey for the acquisition of data in ground-water-quality studies. This report provides guidelines and procedures for the selection and installation of wells for water-quality studies/*, and the required or recommended supporting documentation of these activities. Topics include (1) documentation needed for well files, field folders, and electronic files; (2) criteria and information needed for the selection of water-supply and observation wells, including site inventory and data collection during field reconnaissance; and (3) criteria and preparation for installation of monitoring wells, including the effects of equipment and materials on the chemistry of ground-water samples, a summary of drilling and coring methods, and information concerning well completion, development, and disposition.
