National Water Quality Assessment Program (NAWQA)
Ozark Plateaus Study Unit
The initial, high intensity phase of the Ozark Plateaus NAWQA began in 1991 and continued through 1995. During the high intensity phase, study unit personnel collected ground-water, surface-water, and biological samples from throughout the study unit. Results of this first cycle of studies were summarized in a report and a fact sheet. In 1996, the study unit entered a low intensity phase. Beginning in 2006, additional studies in the Ozark Plateaus will be conducted on effects of nutrient enrichment on stream ecosystems.
The Ozark Plateaus study unit is approximately 48,000 square miles in size and includes parts of northern Arkansas, southeastern Kansas, southern Missouri, and northeastern Oklahoma. The boundaries of the study unit approximate the natural flow boundaries of the Ozark Plateaus aquifer system.
