Abstract

A modified natural gradient point dilution test using a multilayer sampler was conducted in a 20‐m‐thick confined aquifer in a research field near Mobile, Alabama. The horizontal component of the specific discharge along the profile varies by an order of magnitude, from 2.0 to 21.1 m/yr. The modified point dilution test was capable of detecting very large q changes over small vertical intervals. The results obtained by the point dilution test agree with the results obtained in the same aquifer by a forced gradient tracer test over a distance of 6 m (Molz et al., 1988).
