Vertical electrical soundings were used to map the presence or absence of an aquitard separating a shallow, contaminated aquifer from a deeper, uncontaminated one in San Bernardino Valley, California. Correlation of vertical electrical soundings with lithologie logs from adjacent wells allowed us to also map local variations in the elevation of the water table Comparison of known waste sites, the distribution of the aquitard, and elevation of the water table yielded probable directions of contaminant transport. We conclude that there is a significant hazard to municipal water wells due to possible transport of contaminants between the shallow and deeper aquifers.
