Water-quality data for groundwater samples collected by the U.S. Geological Survey from 79 wells in Pike County, Pennsylvania, 1982-2015. Data consist of field properties and results of laboratory analysis for concentrations of inorganic constituents, dissolved gases (methane, ethane and propane), radon-222, gross alpha and beta radioactivity, radium-226, and volatile organic compounds (VOCs) and methane isotopic composition in groundwater samples. Dataset prepared as part of 2015 study for which 79 wells were sampled and includes comparable results for 18 of the 79 wells that were sampled for previous studies in years 1982, 2007, 2011-13. In 2015, groundwater samples from all 79 wells were analyzed for all constituents...

Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2016 over a total distance of 262 line kilometers in the southeastern San Joaquin Valley near Cawelo, California. These data were collected in support of groundwater salinity mapping and hydrogeologic framework development as part of the U.S. Geological Survey California Oil, Gas, and Groundwater program and the California State Water Resources Control Board’s Oil and Gas Regional Monitoring Program. Data were acquired by SkyTEM ApS with the SkyTEM 312 time-domain helicopter-borne electromagnetic system together with a Geometrics G822A cesium vapor magnetometer. The survey was designed to cover the region hydrogeologically downgradient...

Evaluating Decadal Changes in Groundwater Quality: Groundwater quality data were collected from 5,000 wells between 1988-2001 (first sampling event) by the U.S. Geological Survey’s National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled about 10 years later between 2002-2012 (second sampling event) to evaluate decadal changes in groundwater quality. Between 2012 and 2014 (third sampling event), a subset of these networks has been sampled again, allowing additional results to be displayed on the web page: Decadal changes in groundwater quality. Changes to this web page are referred...
This part of the Data Release contains the water-quality data compiled and synthesized from various sources(including data from water-quality samples collected by the USGS in 2015 from 26 sites).

A multivariate regression model was developed to predict zero-order oxygen reduction rates (mg/L/yr) in aquifers across the State of Wisconsin. The model used a combination of dissolved oxygen concentrations and mean groundwater ages estimated with sampled age tracers from wells in the U.S. Geological Survey National Water Information System and previously published project reports from state agencies and universities. The multivariate regression model was solved using the Microsoft Excel solver, with 461 wells used for training and 46 wells held-out for validation. A total of 31 predictor variables were used for model development (56 were tested), including basic well characteristics, soil properties, aquifer properties,...

Depth-to-water data in the San Joaquin Valley, CA were collected in 1910 and published in Mendenhall and others, 1916. These data were used to create a depth-to-water contour of the Valley described in Plate 1 entitled "Map of San Joaquin Valley, California showing artesian areas, ground-water levels and location of pumping plants", which includes a depiction of geographical areas where flowing well (artesian) conditions existed in 1910. These "Areas of flowing wells" have been converted into a digital vector format (ArcGIS Shapefile) for use in future research.

From July to November 2019, 48 environmental samples and four quality assurance and quality control samples were collected throughout the Lake Champlain and Susquehanna River Basins. Samples were collected from 10 production wells and nine domestic wells in the Lake Champlain Basin, and 14 production wells and 15 domestic wells in the Susquehanna River Basin. Of the total wells sampled, 24 were completed in bedrock and 23 were completed in sand and gravel. Approximately 20 percent of samples were collected from wells that previously have been sampled as part of this study in 2005, 2009, and 2014. Groundwater samples were collected prior to any treatment or filtration systems, from existing domestic and production...

Groundwater samples were collected from 60 public supply wells in the Colorado Plateaus principal aquifer. Water quality evaluations of groundwater for drinking water at public supply depths were made with the purpose of summarizing the current quality of source water (that is, untreated water) from public supply wells using two types of assessments; (1) status: an assessment that describes the current quality of the groundwater resource, and (2) understanding: an evaluation of the natural and human factors affecting the quality of groundwater, including an explanation of statistically significant associations between water quality and selected explanatory factors. To provide context for water-quality data, constituent...

Thirty water-supply drinking-water wells were sampled during fall 2018 for a set of constituents including PFAS. Groundwater samples were sent to Maxxam Laboratories (RTI Laboratory contract) to be analyzed for eighteen PFAS using USEPA 537m method. Groundwater age data were collected and analyzed as well in the USGS Reston, Va. laboratory. Quality-control samples including equipment and field blanks, sequential replicate samples, and laboratory spikes, were collected to evaluate and estimate potential contamination bias and measure variability from water-quality data-collection processes. No PFAS were detected in equipment or field blanks indicating that selected equipment, cleaning, sampling, and handling procedures...

From May to December 2017, 48 environmental samples and six quality control samples were collected throughout the Upper Hudson and Central New York River Basins. Samples were collected from nine production wells and 11 domestic wells in the Upper Hudson River Basin, and 14 production wells and 14 domestic wells in the Central New York River Basin. Of the total wells sampled, 22 were completed in bedrock and 26 were completed in sand and gravel. Approximately 20 percent of samples were collected from wells that were previously sampled as in 2007 and 2012. Groundwater samples were collected prior to any treatment or filtration systems, from existing domestic and production wells equipped with permanently installed...

An investigation was done by the U.S. Geological Survey, in cooperation with the California State Water Resources Control Board's Program of Regional Groundwater Monitoring of Water Quality in Areas of Oil and Gas Production, to assess the effects of oil and gas production activities on nearby groundwater resources. During November 2016–September 2017, 30 samples were collected at groundwater wells and 1 sample was collected at a surface-water site. This dataset contains site information and water chemistry results for samples collected near the Lost Hills and North and South Belridge oil fields, Kern County, California. Samples were analyzed for water-quality indicators, major and minor ions, nutrients, trace elements,...

The Mississippi River Valley alluvial aquifer (MRVA) overlies and is bounded by several regional aquifers that make up the Mississippi embayment aquifer system (MEAS) in the central United States. The MRVA, which consists of Quaternary alluvium, is one of the most heavily pumped aquifers in the nation and is a major source of groundwater for irrigation. Large groundwater-level declines in portions of the aquifer have raised concerns about sustainable use of this important resource. An aquifer-scale assessment of groundwater-age categories based on tritium concentrations was completed to better understand groundwater availability and susceptibility. The presence of tritium, a radioactive isotope of hydrogen, in a...

This model archive contains files for a set of groundwater flow, particle tracking, and management optimization models that simulate the area around the Navy-Northrop-Grumman contamination plume on Long Island, New York. These models were developed as in insets from the Long Island Regional “parent” Model, from which perimeter boundary conditions were inherited. In addition to input and output files for these models, this archive contains the modeling workflow python code and source data used to build the model. These materials have been included for repeatability and decision transparency.
