    This spiral-bound book offers detailed direction on how to utilize the hydrogeologic classification system for logging water well boreholes.

    The system, which uses a weather-resistant, two-sided card, provides structure and uniformity to logging wells. The front of the card provides essential gauges for measuring size, color, and aquifer characteristics. The back contains an easy-to-follow flowchart of how to use the classification system.

    The author created the system and his text is easy to follow and accompanied by pictures. The book will enable groundwater professionals to provide better correlation and interpretation of borehole logs.
