Abstract

The geology and structure of an area near Brentwood, Williamson County, Tennessee, were studied to define the potential aquifers and confining units that comprise the groundwater flow system of the area. Four different formations were identified. These formations are, in descending order, the Bigby-Cannon Limestone, the Hermitage Formation, the Carters Limestone, and the Lebanon Limestone. The Bigby-Cannon Limestone and the Hermitage Formation have been affected by recent erosion. Any variation of the Carters Limestone is controlled by pre-Carters erosion of the top of the Lebanon Limestone. The thickness of this formation ranges from 65 to 79 ft. A small scale anticline-syncline pair is evident. This structure is not a result of erosion and also occurs in the T-3 bentonite bed in the Carters Limestone. (USGS)
