This map layer contains the shallowest principal aquifers of the conterminous United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands, portrayed as polygons. The map layer was developed as part of the effort to produce the maps published at 1:2,500,000 in the printed series "Ground Water Atlas of the United States". The published maps contain base and cultural features not included in these data. This is a replacement for the July 1998 map layer called Principal Aquifers of the 48 Conterminous United States.
This dataset includes the magnetotelluric (MT) sounding data collected in 2003 along a north-south profile west of Wendover, Nevada. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also important to know the location and orientation of the Archean/Proterozoic suture zone between these provinces as well as major basement structures within these terranes because they may influence subsequent patterns of sedimentation, deformation, magmatism, and hydrothermal activity. This study was funded by the U.S....
This data set contains the shallowest principal aquifers of the Lake Michigan basin, portrayed as polygons. The data set was developed as part of the effort to produce the maps published at 1:2,500,000 in the printed series "Ground Water Atlas of the United States". The published maps contain base and cultural features not included in these data. This is a replacement for the July 1998 data set called Principal Aquifers of the 48 Conterminous United States.
This draft dataset represents an estimated representation of net annual recharge of surficial aquifers in Wyoming from natural sources. Irrigation or other man-made recharge structures are not represented. Estimated recharge is calculated using a simplistic formula based on soil type and average annual rainfall. The dataset is in raster format with 100 meter cell size. For more details about this dataset, please refer to this report: Hamerlinck, J.D. and Arneson, C.S., editors, 1998, Wyoming Ground-Water Vulnerability Assessment Handbook: Volume 1. Background, Model Development, and Aquifer Sensitivity Analysis: Wyoming Geographic Information Science Center Publication WyGISC 98-01-1, University of Wyoming, Laramie,...

The effects of a dilute (ionic strength = 5 × 10−3 M) plume of treated sewage, with elevated levels (3.9 mg/L) of dissolved organic carbon (DOC), upon the pH-dependency and magnitude of bacterial transport through an iron-laden, quartz sand aquifer (Cape Cod, MA) were evaluated using sets of replicate, static minicolumns. Compared with uncontaminated groundwater, the plume chemistry diminished bacterial attachment under mildly acidic (pH 5.0–6.5) in-situ conditions, in spite of the 5-fold increase in ionic strength and substantively enhanced attachment under more alkaline conditions. The effects of the hydrophobic neutral and total fractions of the plume DOC; modest concentrations of fulvic and humic acids (1.5...

A hydrogeologic framework of the Ozark Plateaus aquifer system was constructed as the base for a groundwater flow model developed as part of the U.S. Geological Survey Water Availability and Use Science Program to aid in the understanding of groundwater availability in select aquifer systems of the United States. The Ozark Plateaus aquifer system study area (hereinafter referred to as the “Ozark system”) is nearly 70,000 square miles and includes parts of Arkansas, Kansas, Missouri, and Oklahoma. A hydrogeologic framework was constructed to represent the altitudes and thicknesses of nine hydrogeologic units within the Ozark Plateaus aquifer system - . the Western Interior Plains confining system, Springfield Plateau...
Please note: a more recent version of this dataset is available. Users are strongly advised to access the newer version of the dataset at https://doi.org/10.5066/P9YGUE2V. The U.S. Geological Survey in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District has produced this dataset of compaction values in the Chicot and Evangeline aquifers in the Houston‐Galveston region, Texas. This dataset shows compaction values of subsurface sediments (mostly in the fine-grained silt and clay layers because little compaction occurs in sand layers) in the Chicot and Evangeline aquifers that were recorded continuously by using...

This dataset contains monthly pumping rates for municipal and industrial (MnI) wells in the Santa Teresa, New Mexico network within the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). In RGTIHM, these wells are considered the Santa Teresa, New Mexico (NMST) group. Monthly pumping rates are presented in units of cubic feet per day for the period from March 1940 through December 2014.

This polygon vector dataset delineates six informal geographic subregions within the model grid of the Rio Grande transboundary integrated hydrologic model and water-availability analysis, New Mexico and Texas, United States, and Northern Chihuahua, Mexico.
This point vector dataset represents 18 surface-water inflow points used as input into the Streamflow-Routing (SFR) Package for MODFLOW-One-Water Hydrologic Flow Model in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). Fourteen of the inflow points represent wastewater treatment plant (WWTP)/water reclamation plant outfalls, two of the inflow points represent electric plant outfalls, and the remaining two inflow points represent gage locations on the Rio Grande below Caballo Reservoir and Bonita Lateral flows near the beginning of the SFR network within the RGTIHM.
This dataset includes the magnetotelluric (MT) sounding data collected in 2005 along an east-west profile north of Wells, Nevada. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also important to know the location and orientation of the Archean/Proterozoic suture zone between these provinces as well as major basement structures within these terranes because they may influence subsequent patterns of sedimentation, deformation, magmatism, and hydrothermal activity.

Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2015 along 769 line-kilometers over a 160-square-kilometer area that includes the Big Sioux aquifer between Sioux Falls and Dell Rapids, South Dakota, USA. Data were acquired with the CGG Resolve frequency-domain helicopter-borne electromagnetic system along with a cesium vapor magnetometer. Files included in this data release are: (1) raw and processed AEM and magnetic data; (2) processed AEM resistivity-depth inversions, and (3) a contractor’s report describing survey parameters, field operations, quality control, and data reduction procedures.

This community catalog serves the Oregon Water Science Center. Community public website: http://or.water.usgs.gov/. The Oregon Water Science Center provides reliable water data and interpretation of data to Federal, State, and local agencies, Tribes, and the public. Our data and study results are widely used to manage Oregon's water resources for the benefit of people and our environment.
In April 2015, a total of 34 passive seismic surveys were conducted in the Cedar River Floodplain. The horizontal-to-vertical spectral ratio (HVSR) method is a passive seismic technique that uses a three-component seismometer to measure the vertical and horizontal components of ambient seismic noise. Seismic noise in the range of approximately 0.1 to 1 Hertz (Hz) is caused by ocean waves, large regional storms, and tectonic sources. A resonance frequency (f0) is induced in the unconsolidated deposits when there is a substantial contrast (greater than 2:1) in shear-wave acoustic impedance between the overburden and the bedrock. The f0 is determined from the analysis of the spectral ratio of the horizontal and vertical...
In 2011, the U.S. Geological Survey, in cooperation with the Town of Newfield and the Tompkins County Planning Department, began a study of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys in the Town of Newfield, Tompkins County, New York. The objective of this study was to characterize the hydrogeology and water quality of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys and produce a summary report of the findings. This dataset contains the well records compiled for this study in West Branch Cayuga Inlet and Fish Kill Valleys, Newfield, Tompkins County, New York.
