The Delaware River is rich in history, ecologically diverse, and critical to the regional economy. Water managers in this basin have a long history of applying innovative, regional solutions to ensure the long-term sustainability of this treasured resource which provides drinking water to over 15 million people in the region.

National Atmospheric Deposition Program (NADP)
The National Atmospheric Deposition Program (NADP) is a collaboration of atmospheric monitoring networks. The purpose of the networks is to collect data to evaluate air quality. Network data also inform science-based actions to protect human health and preserve ecosystems for current and future generations. The NADP National Trends Network (NTN) quantifies the concentration of eight major ions and...
Next Generation Water Observing System: Delaware River Basin
The USGS Next Generation Water Observing System (NGWOS) provides high-fidelity, real-time data on water quantity and quality necessary to support modern water prediction and decision support systems for water emergencies and daily water operations. The Delaware River Basin was the first NGWOS basin, providing an opportunity to implement the program in a nationally important, complex interstate...
Atmospheric nitrogen deposition in the Chesapeake Bay watershed: A history of change
Issue: Atmospheric deposition is one of the principal sources of nitrogen to the Chesapeake watershed with implications for patterns of nutrient loading, anoxia, and eutrophication in the Bay.
Compilation of Mercury Data and Associated Risk to Human and Ecosystem Health, Bad River Band of Lake Superior Chippewa
Purpose and Scope The Natural Resources Department of the Bad River Band of Lake Superior Chippewa, Odanah, Wisconsin has requested assistance with compiling existing mercury (Hg) concentration data from measurements in a variety of environmental media in an effort to evaluate risks to ecosystem and human health and to identify key data gaps that could be addressed through future...
Acidification and Recovery and Development of Critical Loads of Acidity for Stream Ecosystems of the Adirondack Region of New York State
BACKGROUND The Adirondack region of New York has a history of relatively high atmospheric sulfur (S) and nitrogen (N) deposition (Greaver et al. 2012). Adirondack ecosystems have been impacted by these inputs, including soil and surface water acidification, and impaired health and diversity of forest vegetation and aquatic biota. Air quality management, through the Clean Air Act, the U.S...
Mercury Bioaccumulation in Fish in New York's Streams and Rivers
Background Although New York State has more than 70,000 miles of streams and rivers, little is known about the status, distribution, and trends of mercury (Hg) levels in stream fish, or the environmental drivers of these patterns. Streams and their riparian zones provide critical habitat for fish, birds, mammals, reptiles and amphibians, and serve as the interface between aquatic and...
Appalachian Trail MEGA-Transect Atmospheric Deposition Effects Study
The Appalachian Trail (AT), a 14-state footpath from Maine to Georgia, is a unit of the National Park Service that is cooperatively managed and maintained by the National Park Service (NPS), the Appalachian Trail Conservancy, AT Club volunteers, the USDA Forest Service, and other public land-management agencies. Upper elevation and ridge-top ecosystems, which comprise much of the trail...
Development of a Graphical User Interface (GUI) to Predict Streamflow Statistics using USGS Streamstats and Precipitation from Downscaled Global Climate Change Models
Background Climate change during the past century has resulted in changes to precipitation amounts, form (rain vs. snow), as well as frequency and intensity in the northeastern US (Huntington et al., 2009). Additional changes in precipitation are forecast for the 21st Century as the global and regional climate is expected to warm substantially (Hayhoe et al., 2007). These ongoing and...
Estimated Non-reservoir Streamflows of Esopus Creek at Coldbrook and Mount Marion, New York
Problem Statement More than nine million people rely on the New York City Water-Supply System for their daily-drinking water needs. Approximately 40 percent of this water comes from the Schoharie and Ashokan Reservoirs (fig. 1). This water is transported from the Catskill Area to New York City through Esopus Creek and a series of man-made tunnels and aqueducts built starting in the early...
National Acid Precipitation Assessment Program Report to Congress 2011: An Integrated Assessment
Title IV has been successful in reducing emissions of SO2 and NOx from power generation to the levels set by Congress. In fact, by 2009, SO2 emissions from power plants were already 3.25 million tons lower than the final 2010 cap level of 8.95 million tons, and NOx emissions were 6.1 million tons less than the projected level in 2000 without the ARP, or more than triple the Title IV NOx...
Changes in Soil and Stream Water Chemistry in Response to Reduction in Acid Deposition in the Catskills
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...
Mercury Cycling and Bioaccumulation in the Upper Hudson River Basin--Fishing Brook
BackgroundDetailed investigations of mercury cycling and bioaccumulation have been done in the Upper Hudson River basin (upstream of the Hudson River near Newcomb, in New York's Adirondack Mountains, with a focus on the Fishing Brook sub-basin, part of the western headwaters of the Hudson River. This study is part of a National mercury study that includes a concurrent study of McTier...
Field Trip with PAWSC staff to a Delaware River NGWOS station in Philadelphia, Pennsylvania
The Delaware River is rich in history, ecologically diverse, and critical to the regional economy. Water managers in this basin have a long history of applying innovative, regional solutions to ensure the long-term sustainability of this treasured resource which provides drinking water to over 15 million people in the region.
NGWOS Takes Flight
The USGS conducted an aerial electromagnetic survey of the Delaware Bay to collect data on groundwater salinity. Rising sea level, increasing frequency and intensity of coastal storms, and increasing demand for groundwater have amplified the risk of saltwater impacting water supplies in the region.
