Aquifer framework datasets used to represent the Rush Springs aquifer, Oklahoma Aquifer framework datasets used to represent the Rush Springs aquifer, Oklahoma
The Rush Springs aquifer resides in west-central Oklahoma with an area of about 1,400 square miles. The aquifer consists of the Rush Springs Sandstone and the Marlow Formation which are part of the Whitehorse Group of Permian age (HA 730-E). The Rush Springs Sandstone has a maximum thickness of about 300 feet and the Marlow Formation has a maximum thickness of about 125 feet. The aquifer...
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 Kingshill aquifer resides under St. Croix, an Island in the U.S. Virgin Islands. The Island of St. Croix is mountainous in the northwestern and eastern regions of the island and the central and southwest regions contain rolling hills and plains. The Kingshill aquifer underlies the plains of St. Croix. The aquifer is composed primarily of limestone and marl and has a maximum saturated
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 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 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
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 Arbuckle-Simpson aquifer, Oklahoma Aquifer framework datasets used to represent the Arbuckle-Simpson aquifer, Oklahoma
The Arbuckle-Simpson aquifer covers an area of about 800 square miles in the Arbuckle Mountains and Arbuckle Plains of South-Central Oklahoma. The aquifer is in the Central Lowland Physiographic Province and is composed of the Simpson and Arbuckle Groups of Ordovician and Cambrian age. The aquifer is as thick as 9,000 feet in some areas. The aquifer provides relatively small, but...
Aquifer framework datasets used to represent the Pecos River Basin alluvial aquifer, Texas, New Mexico Aquifer framework datasets used to represent the Pecos River Basin alluvial aquifer, Texas, New Mexico
The Pecos River Basin alluvial aquifer, hereinafter referred to as the "Pecos aquifer", is located in western Texas and southeastern New Mexico. The aquifer is primarily composed of alluvial sand and gravel deposits mantled by sand and silt. The Pecos aquifer overlies Permian, Triassic, and Cretaceous-age rocks. The saturated thickness of the aquifer ranges from 0 to 1000 feet. The...
Concentrations of 6PPD and 6PPD-Quinone in a United States reconnaissance of stormwater, surface water, and groundwater, 2018-24 Concentrations of 6PPD and 6PPD-Quinone in a United States reconnaissance of stormwater, surface water, and groundwater, 2018-24
From 2018 to 2024 surface waters (fresh and brackish), groundwater, and stormwater (runoff, re-use) samples were collected from sites with varying landuse (agricultural, forested, and urban) and streamflow conditions and analyzed at the Organic Geochemistry Research Laboratory in Lawrence, Kansas for the tire antioxidant 6PPD (6-p-phenylenediamine; N-(1,3-Dimethylbutyl)-N’-phenyl-p
Phytoplankton Identification and Enumeration Data Collected from Seven Reservoirs in the United States (July to November 2019) Phytoplankton Identification and Enumeration Data Collected from Seven Reservoirs in the United States (July to November 2019)
This dataset contains algal identification and enumeration data for phytoplankton samples collected by the U.S. Geological Survey (USGS) between July 2019 and November 2019 at seven reservoirs across the United States.
