Water and Land Use Investigations In Soluble Rock Terrains

The Ozark Underground Laboratory, Inc. (OUL), is a private consulting and contract studies firm which provides groundwater tracing and other hydrogeological services throughout North America. The OUL has been in continuous full-time operation since 1973 under the direction of Tom Aley, who serves as Principal Hydrogeologist for the firm. The OUL has a full time staff of eight people. We are not affiliated with any academic institution, and we have no academic responsibilities that could interfere with full client service. The OUL has designed and either conducted, or assisted with, over 4,000 groundwater traces in the United States and Canada, in addition to a modest number of traces in Australia, Barbados, Indonesia, New Zealand, and Peru.
