Aquifer framework datasets used to represent the Central Oklahoma aquifer, Oklahoma Aquifer framework datasets used to represent the Central Oklahoma aquifer, Oklahoma

The Central Oklahoma aquifer underlies an area of about 2,900 square miles in central Oklahoma. The aquifer is in the Central Lowland Physiographic Province and consists of Garber Sandstone and the Wellington Formation, which are part of the Sumner Group of Permian age. The maximum thickness of the aquifer is about 1,000 feet with a saturated thickness ranging from 150 to 650 feet. The...

Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico

The Roswell Basin aquifer system is located in southeastern New Mexico. It is composed of an alluvial aquifer and an underlying carbonate-rock aquifer. The aquifer covers an area of about 2,200 square miles and the alluvial aquifer covers about 1,200 square miles of the eastern half of this area. The alluvial aquifer primarily consists of Quaternary sediments and the carbonate-rock...

Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington

The Willamette Lowland basin-fill aquifers (hereinafter referred to as the Willamette aquifer) is located in Oregon and in southern Washington. The aquifer is composed of unconsolidated deposits of sand and gravel, which are interlayered with clay units. The aquifer thickness varies from less than 100 feet to 800 feet. The aquifer is underlain by basaltic-rock. Cities such as Portland...

Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma

The Ada-Vamoosa aquifer resides in the Central Lowland Physiographic Province in east-central Oklahoma and ends at the Kansas State line. The aquifer underlies an area of about 2,300 square miles. The aquifer consists mainly of layers of fine to coarse-grained sandstone irregularly interbedded with shale and limestone. The rocks are in the Ada and the Vamoosa Groups are Pennsylvanian age...

Aquifer framework datasets used to represent the Marshall aquifer, Michigan Aquifer framework datasets used to represent the Marshall aquifer, Michigan

The Marshall aquifer underlies much of the Lower Peninsula of Michigan and has a maximum thickness of 493 feet (Lampe, 2009). The aquifer consists mainly of medium-grained sandstone and is overlain by Pennsylvanian-age rocks and glacial deposits and underlain by the Devonian-Mississippian-age confining unit. The Marshall aquifer is one of the most productive aquifers in the state where
