Aquifer framework datasets used to represent the Southern Nevada volcanic-rock aquifers, Nevada Aquifer framework datasets used to represent the Southern Nevada volcanic-rock aquifers, Nevada
The Southern Nevada volcanic-rock aquifers reside in southern-central Nevada. This group of aquifers can be categorized into welded tuff, bedded tuff, and lava flow aquifers. Each of these categories possess different physical characteristics and have varying degrees of welding and number of interconnected joints. The lithology of these aquifers is primarily dependent on mode of eruption...
Aquifer framework datasets used to represent the Kingshill aquifer, Island of St. Croix Aquifer framework datasets used to represent the Kingshill aquifer, Island of St. Croix

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 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...
