Great share from the Oklahoma Water Resources Center! Oklahoma's only sole source aquifer — the Arbuckle-Simpson — serves the city of Ada as well as many more towns across south-central Oklahoma and is the primary water source for Chickasaw National Recreation Area, which welcomes millions of visitors annually.
Protecting sole-source aquifers is the only way to ensure the long-term health of communities that have no backup water supply. Because these aquifers are critical to their regions, even minor contamination can result in an immediate and significant public health crisis.
Oklahoma's only sole source aquifer is the Arbuckle-Simpson Aquifer in south-central Oklahoma. The EPA has officially designated its eastern portion as a sole source aquifer to protect this limited resource.
