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,...

This model archive provides all data, code, and modeling results used in Barclay and others (2023) to assess the ability of process-guided deep learning stream temperature models to accurately incorporate groundwater-discharge processes. We assessed the performance of an existing process-guided deep learning stream temperature model of the Delaware River Basin (USA) and explored four approaches for improving groundwater process representation: 1) a custom loss function that leverages the unique patterns of air and water temperature coupling resulting from different temperature drivers, 2) inclusion of additional groundwater-relevant catchment attributes, 3) incorporation of additional process model outputs, and...

INTRODUCTION • Concerns over the viability of the fractured bedrock aquifer that provides about 1/3 of Rockland County’s water supply prompted a 5-year study by the U.S. Geological Survey (USGS) to (1) define the hydrogeologic framework of the aquifer, (2) assess conditions within it, and (3) identify other potential sources of water for the County. The study was done in cooperation with Rockland County and the New York State Department of Environmental Conservation. • Population growth in Rockland County to nearly 300,000 people has been paralleled by significant hydrologic changes over the past 50 years –water demand and impervious surface area have increased, and sanitary sewers now serve most areas and discharge...

Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells in Upper Buttermilk valley are finished in sand and gravel, indicating that there is a sand and gravel aquifer in, at least, part of the valley. The Upper Buttermilk Creek/Danby Creek valleys are "through valleys"-- a part of a valley where the bedrock floor rose to land surface and formed a preglacial surface-water divide....

This data release child item contains fiber-optic distributed temperature sensor (FO-DTS) data collected along the western unwalled shoreline of the Bremerton Naval Complex, Bremerton, Washington, USA from July 30, 2020, to August 11, 2020. Continuous profiles of water temperature were collected along a spatially georeferenced fiber optic cable deployed in an out-and-back U-shape with approximately 2- meter distance between the parallel cable lengths by a Sensornet® Oryx DTS FO-DTS (Fiber-optic distributed temperature sensor). Data were collected in a single ended configuration with two channels, Channel_1 and Channel_2, where water temperature was spatially averaged over 1.01- meter linear intervals by the Oryx...

Six hypothetical 1-dimensional models are used to verify and demonstrate new unsaturated-zone heat transport functionality added to MT3D-USGS (version 1.1.0). Because the governing equations describing groundwater solute transport and heat transport have a similar form, MT3D-USGS may be applied to heat transport problems. Published examples of MT3DMS, from which MT3D-USGS is derived, as a heat transport modeling tool have previously been limited to the saturated zone. However, with the publication of MT3D-USGS which added unsaturated zone solute transport capabilities, some additional support (i.e., new source code) is necessary to enable its use as a heat transport simulator where the unsaturated zone also is going...

Over the past 15 years Douglas County, NV has removed production wells in northern Carson Valley from use due to relatively high arsenic concentrations (Carl Ruschmeyer, January 2013, Douglas County Public Works Director, verbal communication). To maintain the supply of water to the public, the town of Minden has been providing water to Douglas County and Carson City. Due to the projected increases in municipal demand, water resource managers are concerned that increasing pumping rates from wells in Minden may change groundwater chemistry and degrade the resource by potentially drawing in arsenic enriched water. Naturally occurring arsenic is one of the most common contaminants in groundwater in the western United...

Summary Fire Island National Seashore (FIIS) occupies 42 km of the barrier island for which it is named that lies off the southern shore of western and central Suffolk County, Long Island, N.Y. Fire Island is underlain by a complex aquifer system consisting of unconsolidated glacial, lacustrine, deltaic, and marine deposits of clay, silt, sand, and gravel that range in age from Late Cretaceous to Holocene. Accelerated sea level rise, storms, rising temperatures, and changes in patterns of precipitation are all expected to drive significant ecological change. Among the most vulnerable resources are the Island’s fresh groundwater resources. The potential for climate-driven changes in the quantity and quality of...

A three-dimensional groundwater flow model, MODFLOW 6, was developed to provide a better understanding of the hydrogeology of the Harney Basin, southeastern Oregon. The model was used to investigate the historical groundwater-level decline and storage loss associated with anthropogenic groundwater demands. The model was calibrated to 1930 through 2018 conditions. This USGS data release contains all of the input and output files for the simulation described in the associated model documentation report (https://doi.org/10.3133/sir20241518)

Green and others (2021) developed a gradient boosted regression tree model to predict the mean groundwater age, or travel time, for shallow wells across a portion of the Great Lakes basin in the United States. Their study applied machine learning methods to predict ages in wells using well construction, well chemistry, and landscape characteristics. For a dataset of age tracers in 961 water samples, the mean travel time from the land surface to the sample location (center of saturated open interval) was estimated for each sample using parametric functions. The mean travel times were then modeled using a gradient boosting machine algorithm with cross validation tuning of model hyperparameters. The model contained...

This data set was compiled to support the development of a model of oxygen reduction rates in Wisconsin groundwater wells; a model which is part of a Groundwater Nitrate Decision Support Tool for Wisconsin. Data were compiled from previously published studies with data collection from 1987 to 2009. Only data describing redox condition, groundwater age, depth to water, and well construction were compiled, though a majority of these studies presented a broader suite of analytes. Parameters compiled include dissolved oxygen, nitrate, indicators of denitrification, and parameters used in estimating groundwater age including tritium and chlorofluorocarbon (CFC) concentration. Age estimates based on these data, where...

The U.S. Army Fort Irwin National Training Center (NTC), approximately 35 mi north-northeast of Barstow, California, covers approximately 1,177 square miles, and is comprised of ten groundwater basins, three of which have been subdivided into subbasins on the basis of additional hydrologic testing. Since the early 1990s, the U.S. Geological Survey (USGS) has been studying water resources issues at Fort Irwin. One issue of concern is the potential effect of groundwater development resulting from planned training expansion and infrastructure at the NTC on natural springs and seeps, an important water source for wildlife. In 2010, the USGS entered into cooperative agreements with the U.S. Army to complete studies of...
