CHALLENGES OF THE ARBUCKLE-SIMPSON STUDY

Ross*, R R. CHALLENGES OF THE ARBUCKLE-SIMPSON STUDY. Presented at Oklahoma Water Symposium 2003, Stillwater, OK, 10/29-30/2003.
Description:
The Arbuckle-Simpson aquifer underlies more than 500 square miles in south central Oklahoma. The aquifer is the source of many springs, including Byrds Mill Spring, Ada's primary drinking water source, and those in the Chickasaw National Recreation Area. The aquifer supplies water to Blue River and Pennington, Mill, Oil, Honey, and Hickory Creeks. The U.S. Environmental Protection Agency has designated the aquifer's eastern portion as a sole source for drinking water to approximately 39,000 people in Ada, Sulphur, and other areas of southeast and south central Oklahoma.
A five-year study will seek to understand the region's complex geology and hydrology so that a water resource management plan that protects the region's springs and streams can be developed and implemented. Key to the understanding of the aquifer system is how groundwater and surface water interact. Complex geologic features such as fractures, faults, and solution channels affect the aquifer's ability to store and transmit water. Experts in various fields will work together to ensure sound science and appropriate methods are used to obtain the most pertinent information. Groundwater flow modeling will be used as tool to improve understanding of the aquifer and to assist in the water resource decision-making process.
