The U.S. Geological Survey's National Water-Use Program (formerly the National Water-Use Information Program) is responsible for compiling and disseminating the nation's water-use data. Established by USGS in 1978, the USGS National Water-Use Program builds on the legacy of the Estimated Use of Water in the United States report series, begun in 1950 and produced every 5 years. The National Water-Use Science Project is a part of the National Water Census (NWC), which supports research focused on improving methods of collection and estimation of water-use data. Water use is a key component of the water-budget approach of the NWC. Goals of the National Water-Use Program: Analyze the source, use, and disposition of...

Problem - The demand for water in New York State is unevenly distributed. Because increasing competition for local supplies could lead to shortages, it is expedient to know how and where water is withdrawn, delivered, and used. There are many dimensions to water-use issues, and all should be considered to develop a full understanding of the use and delivery of water in the State. In order to apply water-use information to problems of water-demand management, many data elements need to be collected and stored in a convenient location and format. The categories of water use most commonly considered include public-water supply, domestic, thermoelectric power generation, industrial, irrigation and, to a lesser degree,...
A disproportionate amount of research in water chemistry has been directed towards defining trace levels of organic contaminants in water whereas the structures and characteristics of natural organic substances, in the dissolved, suspended, and bed sediment phases, are very poorly understood. A better knowledge of the nature of natural organic substances in water is essential to the advancement of many diverse sciences, such as organic geochemistry, aquatic biology, soil science, hydrology involving contaminant transport, and even atmospheric chemistry involving carbon cycle research. The Water Resources Division is conducting significant research on the nature of humic substances in water, which comprise less than...

Natural organic polyelectrolytes are highly active materials that are present in practically all natural water systems. They interact with both organic and inorganic pollutants and nutrients, influencing, and in many instances, controlling the toxicity, rate of movement, persistence and rate of degradation of the pollutants and nutrients in aquatic environments. Detailed knowledge of the chemistry of natural organic polyelectrolytes is therefore of primary importance in understanding the chemical changes that affect all of the components of natural water systems. Organic polyelectrolytes are partially eliminated from drinking water by coagulation and chlorination; however, the products of chlorination are not known....
My research program is multifaceted and involves the development of integrated hydrological, geochemical, and biological knowledge on the source-to-receptor approach to assessing impacts of emerging contaminants (hormones, personal care products, pharmaceuticals, commercial cleaning products). This applied research is targeted on issues important to water-resource managers and policy makers, and the results communicated to a spectrum of stakeholders. The current focus of my research is the impact of biologically-active contaminants on aquatic organisms, and the relationship to receiving water (surface water and groundwater) attenuation capacity. Several major classes of contaminants are being investigated – endocrine...

A major focus of the NAWQA Program in its second decade (2002-2013) is on regional- and national-scale assessments of groundwater-quality status and trends in principal aquifers. The U.S. Geological Survey Office of Groundwater has identified 62 principal aquifers in the U.S. (U.S. Geological Survey, 2003). About 1/3 of the Nation's principal aquifers are the focus of water-quality assessments at the regional scale by NAWQA. The NAWQA framework for principal aquifer assessments considers the physical setting of the aquifer, in addition to its susceptibility and vulnerability to contamination.

Innovative Conservation incentives beyond easements and fee simple purchase are needed for conservation in Florida. In east central Florida, citrus farm owners and agencies have developed a method of storing additional water on shallow citrus groves called water farming. This water storage will help remove harmful point source discharges to the Indian River Lagoon. In support of the development and implementation of wildlife regulatory assurance for Dispersed Water Management (DWM) projects in the Northern Everglades, especially for Water Farmers in the St. Lucie River and Estuary Watershed, the PI provided coordination to support development of a multi-party agreement among USFWS, FWC, FDACS, SFWMD, SJRWMD, and...

Surface-water models are being developed to simulate streamflow at existing USGS gaging stations and other ungaged locations in and upstream of the Coastal Basins of the Carolinas. The models will be used to simulate the potential effects of projected changes in water-use, climate, and urbanization through the year 2065. The Soil and Water Assessment Tool (SWAT) is being used to develop the models. The SWAT model is a physically-based watershed model with the capability of incorporating water-use data. The model operates on a daily time step, which is necessary to support the data input requirements of future ecological response modeling. The models are being calibrated to the period 2000-2014 and will subsequently...

Riparian and aquatic ecosystems in semiarid landscapes like Southwest Wyoming contribute significantly to regional biodiversity. Long-term monitoring data that describe streamflow, surface-water quality, and groundwater levels are needed for assessing possible effects of changes in land use, land cover, and climate on those ecosystems. With WLCI funding, surface-water quality has been monitored at four sites, and groundwater levels have been monitored at one site. The monitoring sites were selected to provide baseline characterization of the upper Green River Basin and the Muddy Creek watershed. All data are collected according to USGS methods (Wagner and others, 2006; Kenney, 2010; Sauer and Turnipseed, 2010; Turnipseed...
The project focuses on the use of analytical techniques that we have developed to support a wide range of studies in water-rock interaction, integrating solid phase mineralogy and elemental chemistry and clay mineralogy into hydrologic and contaminant studies.

This dataset describes irrigation water use in Kansas in 2015. Volumes of water used, irrigated area, and average irrigation application depths are provided for three sets of subareas: (1) Irrigation water use analysis regions that include Groundwater Management Districts (GMDs) with the areas outside of GMDs divided into eastern, central, and western Kansas; (2) Regional Planning Areas (RPAs), which are 14 areas determined by the Kansas Water Office based on hydrologic and administrative boundaries, each with a set of goals outlined in the Kansas Water Vision (https://kwo.ks.gov/water-plan/water-vision); and (3) the 105 Kansas counties. Volumes of water used, irrigated area, and average application depths are also...

Global change processes are producing shifts in temperature, precipitation, and seasonal streamflow regimes across North America. Much of the floodplain hydrology in the U.S. is managed through water control operations, often implemented on short time scales (e.g., weekly decisions), in response to short-term changes in precipitation. This operational model does not account for potential long-term trends, such as increased recurrence or shifts in seasonal timing of high flow events within a year. Therefore, polices that only focus on short-time scales and recent historic conditions may not perform as well under altered climate regimes. This uncertainty in future floodplain conditions is concerning for a variety...
There are a variety of ground-water resource and contamination problems that involve determining the state of ground water and detecting or predicting changes in the ground-water environment. Most approaches to ground-water monitoring network design avoid a rigorous formulation of the monitoring objectives and fail to consider the important processes controlling the movement of ground water and migration of ground-water contaminants. It is unlikely that such approaches to network design will be able to effectively and efficiently monitor the subsurface environment in the face of limited resources. This research aims to develop statistically sound and simulation based methods for ground-water monitoring network design....
Ground-Water solute-transport simulation modeling is an important tool that aids in the analysis of ground-water contamination problems, both actual and potential. Accidental spills, leakage, and waste disposal operations can lead to ground-water contamination. The ability to analyze and predict the movement of solutes in ground-water systems is necessary to assess the effects of a contamination situation or properly design a waste-disposal operation. Laboratory experiments are essential to understanding geochemical reactions in the field and for obtaining the necessary reaction coefficients and rate constants used in transport models. Simulation modeling also is used to compare alternative strategies for aquifer...

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...
