Ground‐water contamination in the arid southwestern United States often shows up in ground‐water samples from deep water‐supply wells. For water‐supply wells with large or multiple perforated intervals, collection of depth‐specific samples in conjunction with spinner flowmeter measurements within the well while pumping may be used to estimate the vertical distribution of contamination in aquifers from which the well draws ground water. This paper presents some of our experience with spinner logging and depth‐specific sampling in water‐supply wells, as well as methodology, general assumptions, and limitations of this technique for investigating vertical ground‐water quality.
