Salinity dynamics in the Delaware Bay estuary are a critical water quality concern as elevated salinity can damage infrastructure and threaten drinking water supplies. Current state-of-the-art modeling approaches use hydrodynamic models, which can produce accurate results but are limited by significant computational costs. We developed a machine learning (ML) model to predict the 250 mg...

Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the 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 again approximately 10 years later...

Heavy rainfall occurred across Pennsylvania on September 1 and 2, 2021, as a result of the remnants of Hurricane Ida. Much of eastern and southcentral Pennsylvania received five to ten inches of rain and most of the rainfall occurred in a little more than six hours. Widespread substantial flooding occurred in the area, particularly impacted was the city of Philadelphia and surrounding...

The algorithms in this data release implement a State-Space Model (SSM) of vertical infiltration through the unsaturated zone and recharge to the water table. These algorithms build on previous investigations available at https://doi.org/10.1029/2020WR029110 and https://doi.org/10.1111/gwat.13206. The SSM is defined by observed states (i.e., the water-table altitude) and unobserved...

The data in this data release are from an effort focused on understanding social vulnerability to water insecurity, resiliency demonstrated by institutions, and conflict or crisis around water resource management. This data release focuses on the conflict in crisis aspects of work. To characterize crisis a dual-prong, qualitative triangulation was used to identify and provide context for...

This data release contains records from research focused on understanding social vulnerability to water insecurity, resiliency demonstrated by institutions, and conflict or crisis around water resource management. This data release focuses on social vulnerability to water insecurity. The data were derived from a meta-analysis of studies in the empirical literature which measured factors...

This data release contains inputs for and outputs from hydrologic simulations for the conterminous United States (CONUS) using the Precipitation Runoff Modeling System (PRMS) version 5.1.0 and the USGS National Hydrologic Model Infrastructure (NHMI, Regan and others, 2018). These simulations were developed to provide estimates of the water budget for the period 1950 to 2010. Specific...

The National Atmospheric Deposition Program/National Trends Network (NADP/NTN) was initiated in 1978 by the Association of State Agricultural Experiment Stations to monitor long-term atmospheric chemistry and the effects pollutants have on aquatic and terrestrial systems. As of fall 2023, precipitation was being collected at approximately 260 NTN sites in the United States, including...

The U.S. Geological Survey (USGS) collected porewater samples from nine suction lysimeters in 2018, 2019, and 2021 for analysis of organic and inorganic constituents from the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, MN. In August of 1979, approximately 1,700,000 L (liters), or 10,700 barrels, of crude oil spilled onto a glacial outwash aquifer...

SurfVelTools is a Python application and user interface for computing parameters associated with the Probability Concept method (Fulton and others, in review) parameters using velocity profile data collected in the stationing where the maximum in-channel velocity occurs. SurfVelTools will also compute streamflow (discharge) for a given Probability Concept result given a known cross...

The Marcellus Shale Energy and Environment Laboratory (MSEEL) is part of the Northeast Natural Energy LLC (NNE) production facility on the Monongahela River in Monongalia County, West Virginia, USA. Natural gas extraction in the area creates large volumes of wastewater that may contain chemical compounds that pose risks to humans, animals, and the environment. The U. S. Geological Survey...

Atmospheric deposition of reactive nitrogen (Nr) can impact the soil microbial community structure and function and thus ecosystem processing and export of nutrients. Ecosystem response to atmospheric inputs of nitrogen depends on several factors, including elevational climate conditions (freeze/thaw cycles, precipitation), geology, soil and vegetation type, N speciation and microbial...
