Data Testing, Inc. has been specializing in the analysis of soils, concrete, asphalt, water, and wastewater since 1959, when we first opened our doors under the name of Fort Smith Testing Company. In the early 1970's we began water and wastewater analysis in accordance with NPDES permits.

Over the years, our commercial testing laboratory has served municipal, industrial and private enterprise clients throughout eastern Oklahoma and most parts of the State of Arkansas.

Whether your project is large or small, for results you can count on, turn to the company that has a long-standing reputation for consistent quality of testing services.
