Perturbations on the earth's magnetic field may coincide with groundwater bodies; various geologic formations have differing magnetic signatures. Some of the formations are water bearing; some are not. The magnetic field perturbations were plotted and numerous independent, individual dowsing tests were made at 4 principal locations. Objective was to see if water dowsers (1) obtain results which are independently corroborative and (2) obtain results which correlate in some way with magnetic field plots of the dowsed areas. About 150 people participated in the experiment over a one year period. Chi-square tests show considerable statistical significance. Nearly all the people involved in the project experienced dowsing reactions though most had never dowsed before. Some evidence exists of correlation between magnetic gradient changes and dowsing reactions. Concern is expressed that this report may be used to prove dowsing is an effective means of finding water if certain statements are taken out of context. It is emphasized that no wells were dug, tests by a few experienced dowsers did not have results better than novices, and only by statistics was it shown that some kind of undefined information might be present.
