Arbuckle Group Deep Fossil Aquifer — South-Central Kansas
Extremely deep Cambrian-Ordovician Arbuckle Group dolomite beneath south-central Kansas. Contains ancient fossil brine and freshwater zones at 3,000+ feet depth. The Arbuckle is a major target for produced water disposal from oil and gas operations — injection has been linked to induced seismicity in the region.
