Aquifer testing was conducted in the Paradox Valley alluvial aquifer in Montrose County, Colorado, including short-term (slug tests) and long-term (pumping tests) stresses on the hydrologic system to determine hydraulic properties of the aquifer. Slug tests were conducted at four wells in March 2013, with only one well producing data that could be interpreted using analytical solutions. In the other three slug tests, water-level displacement was not instantaneous and displayed substantial noise meaning that the analytical solutions could not be applied. Pumping tests were conducted in March through June of 2013 by initiation of pumping at seven production wells screened in the aquifer and observation of water-level...

Problem - Increasing development within the Shenandoah Valley in recent years has placed additional demands on the region’s water resources. The sedimentary rocks in the Valley have been compressed and folded by tectonic forces to form a 5-km deep basin. Ground water, a principal component of the available water supply, flows through fractures in the sedimentary and crystalline rocks that underlie the Valley. Bedding fractures in the rocks are angled downward along the dip of the folds, allowing ground water to penetrate deeply below land surface—fresh water is obtained from wells over 800 ft deep in the Valley. Objectives - Develop a ground-water-flow model to simulate movement of ground water and estimate the...

Summary This study represents the first attempt to examine the spatial and seasonal variations of the surface water budget by using state-of-the-art datasets for sixteen large Canadian drainage basins with a total area of 3.2 million km2. The datasets used include two precipitation grids produced using measurements and reanalysis models, land surface evapotranspiration and water surface evaporation estimated using the EALCO model, streamflow measured at hydrometric stations, and total water storage change derived from GRACE satellite observations. The monthly water imbalance resulted from these datasets varied from 7.0 mm month−1 to 21 mm month−1 among the studied basins, which was 30% on average of the corresponding...

Clean water is important for a variety of uses, including drinking, recreation, and as habitat for aquatic species. Nonpoint-source pollution, such as nutrients, sediment, and pesticides from agricultural runoff, is a major cause of impaired water quality in the United States . Vegetation and soil in natural land cover help to remove pollutants from runoff water before it reaches streams and other waterways by slowing water flow and physically trapping sediment. To assess the spatial distribution of water purification potential in the southeastern United States, we mapped the demand for purification as the total area of agricultural land and the supply of natural land cover in the flowpath over which water moves...

Problem The quality of surface water has important effects on human and ecological health. Surface water is an important drinking water source and is used for swimming, fishing, and recreation, and the quality of surface water can have profound effects on the health, diversity, and resilience of ecological communities. The New York State Department of Environmental Conservation (NYSDEC) is tasked by the U.S. Environmental Protection Agency (USEPA) to monitor ambient water quality of the State. The NYSDEC is also tasked to develop Total Maximum Daily Loads (TMDLs) for state waters that fail to meet their intended use. A critical first step in maintaining high quality of surface-water is assessment of existing...

The Rosenberg Regional Forum was held in Yellowknife, in Canada’s Northwest Territories between June 9th and 12th, 2009. The goal of the forum was to facilitate an exchange of information and experience that would benefit the management of water resources in the Northwest Territories. The objective of the forum was to inform the development of an NWT Water Resources Stewardship Strategy by providing a venue for discussion amongst distinguished scholars who are familiar with the science of water management and alternative approaches to water management around the globe.

Problem - The U.S. Geological Survey (USGS) provided technical assistance between 2001 and 2013 to the U.S. Environmental Protection Agency (EPA) in an investigation of the presence of chlorinated solvents (trichloroethylene and degradates) in ground water in the Middle-to-Lower Devonian and Upper Silurian carbonate bedrock southwest of Auburn in Cayuga County, N.Y. Pieziometric and water-quality data from the wells indicate that contaminants may have migrated in the bedrock as far as 7 miles toward discharge areas that are in an adjacent surface-water basin. The ground-water contamination site was added to the Super Fund priority list in 2003. Objectives - The objective of the work is to characterize the stratigraphy,...

PROBLEM Hook Pond, an 83-acre freshwater pond in East Hampton, N.Y., has historically shown indications of impaired water quality. Impairments in this shallow pond include elevated nutrient concentrations and low dissolved oxygen concentrations in bottom waters as a result of current and historical land-use practices (Lombardo, 2015). Recent (2016) harmful algal blooms in Hook Pond and other eastern Long Island freshwater bodies have spurred local concerns about the loading of nutrients from septic systems to groundwater (and ultimately to surface water), and land-use practices that contribute to contaminated stormwater runoff. To properly evaluate the basic ecological health of the pond, an understanding of the...

Integrated land- and water-use planning strategies are gaining attention as means to inform consideration of more water-efficient urbanization patterns in response to uncertain water availability. We coupled climate and land change projections with empirically-derived coefficient estimates of development-related water demand to project water demand under future conditions of environmental change. Development-related water demand, used to characterize the water footprint of urbanization, is classified as the combined use of public water supply, domestic self-supply and industrial self-supply. We simulated two scenarios of urban growth from 2012 to 2065 using the FUTure Urban-Regional Environment Simulation (FUTURES)...

Forest- Data collected once using GIS prior to fish sampling. Our approach was to focus the study on smaller, headwater catchments because larger streams drained areas containing both hemlock and mixed hardwood forest, making forest-specific comparison intractable. In addition, most of these larger watersheds were impacted by humans (e.g., impoundments, agriculture, quarries) that could confound our assessment of the influence of hemlock. Even after limiting the study to headwater catchments, other possible confounding factors remained; we controlled for landscape variability (i.e., terrain and stream size) through the sampling design and we excluded others (i.e., minimum catchment area,beaver activity) through...

Summary The Environmental Protection Agency’s (EPA) Long Term Monitoring (LTM) network has supported the collection of stream chemistry data in the Catskills since the 1990s. Trends in stream chemistry have periodically been evaluated in these streams but the most recent assessments only extend through the early 2000s. An updated assessment of stream chemistry trends will help evaluate the effects of recent substantial declines in acid deposition during the last decade. This study will evaluate changes in surface water chemistry from 1991 through 2013 at 5 stations in the Neversink and Rondout watersheds in the Catskill Mountains of New York. The results will be compared to changes in atmospheric deposition...
