Advancing the science of groundwater sampling, this volume explains why many of the sampling methods still employed today are of questionable value, and goes on to offer readers methods that are both more reliable and ultimately cost effective. The author, a top authority in the field, details the factors that impact sampling such as formation and well hydraulics; sampling point installation and maintenance; purging and sampling device selection; water-level measurement methods; equipment cleaning methods; and sample pretreatment, collection, handling, and shipping. He also fully examines the processes that occur in sampling points, between sampling events, and during sample collection activities.
