SEAWAT model used to evaluate water management issues in the Santa Barbara and Foothill groundwater basins, California

The city of Santa Barbara, in cooperation with the U.S. Geological Survey (USGS) California Water Science Center,
developed a three-dimensional density-dependent groundwater-flow and solute-transport model (the Santa Barbara
Flow and Transport Model, or SBFTM), based on an existing groundwater-flow model, to simulate seawater intrusion
into the Santa Barbara basin under

DDT and related compounds in pore water of shallow sediments on the Palos Verdes Shelf, CA

For nearly two and a half decades following World War II, production wastes from the world’s largest manufacturer of technical DDT were discharged into sewers of Los Angeles County. Following treatment, the wastes were released via a submarine outfall system to nearshore coastal waters where a portion accumulated in shallow sediments of the Palos Verdes Shelf (PVS). An investigat

FTS RSS Field Test, Wolf River, 2016

Two identical Radar Stage Sensors from Forest Technology Systems, were evaluated to determine if they are suitable for U.S. Geological Survey (USGS) hydrologic data collection. The sensors were evaluated in laboratory conditions to evaluate the distance accuracy of the sensor over the manufacturer’s specified operating temperatures and distance to water ranges. Laboratory results we

Metabolism estimates for 356 U.S. rivers (2007-2017): 2b. Site catchment boundaries

This dataset provides shapefile outlines of the catchments contributing to sites where metabolism was or could have been estimated. The format is a shapefile for all sites combined (.shp, .shx, .dbf, and .prj files). This dataset is part of a larger data release of metabolism model inputs and outputs for 356 streams and rivers across the United States (https...

Habitat Maps for the Cache Creek Settling Basin, Yolo County, California

The geospatial data presented here as ArcGIS layers denote landcover/landuse classifications to support field sampling efforts that occurred within the Cache Creek Settling Basin (CCSB) from 2010-2017. Manual photointerpretation of a National Agriculture Imagery Program (NAIP) dataset collected in 2012 was used to characterize landcover/landuse categories (hereafter habitat classes

MODFLOW-NWT data sets for simulation of Effects of Surface-Water and Groundwater Inflows and Outflows on the Hydrology of the Tsala Apopka Lake Basin in Citrus County, Florida

The U.S. Geological Survey, in cooperation with the Southwest Florida Water Management District,
calibrated a model to quantify the inflows and outflows in the Floral City, Inverness, and Hernando
pools of the Tsala Apopka Lake basin in Citrus County, Florida. The calibrated model, which uses
MODFLOW-NWT version 1.1.2, simulates hydrologic changes in pool stages, groundwa

Water chemistry data for Fourmile Creek Watershed, Colorado, 2010-2015

Extreme climate events– such as hurricanes, droughts, ice storms, extreme precipitation, and wildfires– have the potential to cause large changes in watershed processes, response, and function. A five-year post-wildfire study of stream chemistry in the Colorado Front Range USA, enabled the analysis of the effects these events have water quality, which is published

Thermistor data collected along the Quashnet River, Mashpee/Falmouth MA

Heat is used as a tracer for a variety of physical hydrogeological process. Several types of instruments are used to measure the temperature of surface water and saturated sediments. In the Quashnet River we have been using methods that include: infrared, fiber-optic distributed temperature sensing, and individual logging thermistors. The latter type of data (thermistor) are described a

Survey of major and trace elements in stormwater runoff from across the United States, 2016 to 2017.

This study focuses on providing a broad-scale assessment of composition of water chemistry in urban stormwater runoff. The stormwater runoff is a source of recharge to groundwater by Green Infrastructure (GI) practices or it may become a source of recharge to groundwater to reduce stormwater volumes to surface waters or augment groundwater supply. The chemical composition of the stormwater r...

Fish and selected physical and chemical water-quality data for the U.S. Geological Survey Midwest Stream Quality Assessment

In 2013, the first of several Regional Stream Quality Assessments (RSQA) was done in the Midwest United States. The Midwest Stream Quality Assessment (MSQA) was a collaborative study by the U.S. Geological Survey National Water Quality Assessment and the U.S. Environmental Protection Agency National Rivers and Streams Assessment. One of the objectives of the RSQA, and thus the MSQA%2

Toxicity Data for Groundwater Contaminated by Petroleum Hydrocarbons near Bemidji, MN (2016)

Management of petroleum-impacted waters by monitored natural attenuation (MNA) requires an understanding of the toxicology of both the original compounds released as well as the transformation products formed during natural breakdown. Here, we report data from a groundwater plume consisting of a mixture of crude oil compounds and transformation products resulting from a crude-oil release in...

Natural gradient, lakebed tracer tests using nitrite in a nitrate-contaminated groundwater discharge zone in Ashumet Pond, Massachusetts

The U.S. Geological Survey Toxic Substances Hydrology Program at Cape Cod has been investigating the fate and transport of a treated-wastewater, groundwater contaminant plume. A portion of the contaminated groundwater discharges into Ashumet Pond, a kettle hole, freshwater lake. A study was conducted from June 2013 to June 2015 to document transport, transformation, and discharge of d
