MODFLOW2000_FMP1_1 model used to simulate the groundwater flow of the Central Valley Aquifer, California

A three-dimensional groundwater flow model (MODFLOW200-FMP1_1) of the Central Valley in
California was developed to aid water managers in understanding how water moves through the
aquifer system, to predict water-supply scenarios, and to address issues related to water
competition. The USGS Groundwater Resources Program made a detailed assessment of
groundwater...

Agricultural Pesticide Use Estimates for the USGS National Water Quality Network, 1992-2014: Version 2

The National Water Quality Network (NWQN) for Rivers and Streams includes 113 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program (NWQP). The NWQN represents the consolidation of four historical national networks: the USGS National Water-Quality Assessment (NAWQA) Project, the USGS National Stream Quality Accountin

MODFLOW-NWT groundwater flow model and GWM-VI optimization code for the Little Plover River Basin in Wisconsin's Central Sand Plain

The Little Plover River groundwater flow model simulates three-dimensional groundwater
movement in and around Wisconsin’s Little Plover River basin under steady-state and
transient conditions. The groundwater flow model uses the U.S. Geological Survey’s
MODFLOW-NWT modeling code. This model explicitly includes all high-capacity
wells in the model domain and simulates...

Conterminous U.S. mapping of household income at the block group scale adjusted for cost-of-living for the period 2013-2014

Household income is a potential predictor for a number of environmental influences, for example, application of urban pesticides. This product is a U.S. conterminous mapping of block group income derived from the 2010-2014 Census American Community Survey (ACS), adjusted by a 2013 county-level Cost-of-Living index obtained from the Council for Community and Economic Research. The resul

Description of core collected during installation of a Wasatch aquifer monitoring well in the Green River Basin, Sublette County, Wyoming

A monitoring well was installed in the Wasatch aquifer in the Green River Basin, Sublette County, Wyoming in August 2015. Core collected during drilling activities was described to a depth of 170 feet. The data release contains a detailed description of the lithology and physical characteristics of the core sections, as well as numerous photographs. The data release was produced in complian...

MODFLOW-LGR data sets for the Great Basin carbonate and alluvial aquifer system model version 3.0: Revisions in southwestern Utah and east central Nevada

A new version of previously published steady-state numerical groundwater flow models of the Great Basin
carbonate and alluvial aquifer system (GBCAAS), and was developed in conjunction with U.S. Geological
Survey (USGS) studies in Parowan, Pine, and Wah Wah Valleys, Utah. This version of the model is
considered to be GBCAAS v. 3.0 and supersedes previous versions. This mo

Pesticide concentration and streamflow datasets used to evaluate pesticide trends in the Nation’s rivers and streams, 1992-2012 (input)

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitoring has...

SUTRA model used to evaluate the freshwater flow system on Roi-Namur, Kwajalein Atoll, Republic of the Marshall Islands

A three-dimensional, groundwater model (SUTRA) was developed to understand the
effects of seawater washover on the freshwater lens of Roi-Namur, Kwajalein Atoll,
Republic of the Marshall Islands. The model was calibrated by using observation
data collected from 1990 through 1991 and 2008 through 2010. This USGS data
release contains all of the input and output files for...

Falls River near Squirrel, ID (YFAL)

Falls River near Squirrel, Idaho (YFAL) Sample Collection: Samples were collected near the USGS stream gage 13046995 (Latitude 44°03'43", Longitude 111°09'07" NAD83). At the time of collection, all waters samples were filtered through a syringe filter (0.45-micrometer). Two splits of the filtered water were retained for chemical analyses, including an

MODFLOW-2000 and MODPATH5 model data sets used to evaluate the effects of changes in pumping on regional groundwater-flow paths, 2005 and 2010, and areas contributing recharge to discharging wells, 1990-2010, in the vicinity of North Penn Area 7 Superfund

A three-dimensional, groundwater-flow model (MODFLOW-2000) and a particle-tracking program
(MODPATH5) were used to evaluate the effects of changes in pumping on regional groundwater-flow
paths, 2005 and 2010, and areas contributing recharge to discharging wells, 1990-2010, in the vicinity
of North Penn Area 7 Superfund site, Montgomery County, Pennsylvania. The stea
