The Ozark Underground Laboratory, Inc. (OUL) is devoted to helping clients find solutions to groundwater issues and understanding the causes of and remedies to those issues.  The OUL values the environment as the greatest available resource to any community and believes in implementing best hydrogeological and environmental practices to protect and integrate communities and their environments.  The OUL is committed to excellent quality of work with emphasis on attention to detail and successful dye tracing investigations.  The OUL wants to take the time to listen to you and understand your situation as clearly as possible so as to provide the best service possible.

The OUL is focused primarily on land and water use issues in karst and fractured rock landscapes.  Emphasis is placed on interactions between surface activities and resulting subsurface impacts.  Many clients also utilize the OUL for its ability to analytically detect fluorescent tracer dyes, some of which can be detected in the low parts per trillion range using a Shimadzu RF-5301PC Spectrofluorophotometer and proprietary software developed by the OUL.

The OUL has conducted numerous investigations and projects for various federal agencies; these have included the U.S. Forest Service, Bureau of Land Management, National Park Service, Department of Energy, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, U.S. Army, U.S. Navy, and the U.S. Army Corps of Engineers.  In addition, the OUL has conducted work for numerous state, municipal, corporate, and private clients, some of those entities on long term master projects spanning years.
