Problem - In August 2000, eleven sites were sampled from 9 streams within the Croton watershed for pharmaceuticals and other organic compounds associated with wastewater as part of a national study of these compounds in streams receiving wastewater discharges. Results from the national study indicated that streams in the Croton Reservoir downstream of sewage treatment plants had concentrations of target compounds. Detected compounds included pharmaceuticals, detergent degradates, insecticides, caffeine, and other organic compounds (Kolpin and others, 2002). The results indicate that these compounds are commonly present in streams below wastewater treatment plants (WWTPs). Many of these compounds have not been...
Problem The shallow groundwater of Nassau and Suffolk Counties is prone to contamination from current land-use, including agricultural, residential, and recreational. The aquifer system of Long Island is highly susceptible to human-derived contamination, in particular, because the soils and underlying sediments are generally composed of sandy, permeable materials that allow contaminants to move readily from the land surface into the groundwater below. Of increasing concern are the human-derived contaminants stemming from past and present uses of pesticides. In addition to the threat of direct runoff to adjacent waterbodies, pesticide transport through the shallow aquifer from inland sources may discharge to the...

The NYCDEP Stream Management Program (SMP) is responsible for developing stream management plans for NYC water supply watersheds in the Catskill Mountains, New York State. This mostly forested region of Pleistocene glacial deposits over sedimentary rocks ranges in elevation from approximately 600 to 4,120 feet above sea level; average annual precipitation ranges from 36 to >60 inches/year. The SMP uses fluvial geomorphology as a framework for stream assessment, restoration and monitoring. Bankfull discharge, a common surrogate for channel forming discharge, forms a basis for assessing and classifying stream morphology (Rosgen, 1994). The SMP documented bankfull discharge and associated stream geometry for 41 cross...

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an appropriate manner. Many organizations have undertaken assessments of this discharge and loading for discrete groundwater source areas and (or) receiving surface waters, applying a variety of techniques and assumptions. In part, this is because there is no delineation of recharge areas to the island’s groundwater-fed streams and estuaries...
BACKGROUND Long Island Sound has 600 miles of coastline and there are over 23 million people living within 50 miles of its shores. In response to water-quality issues and nitrogen pollution in the Sound, Congress created the Long Island Sound Study (LISS) in 1985. LISS is a partnership of federal, state, and local government agencies, private organizations and educational institutions working together to restore and protect the Sound. The USGS New England and New York Water Science Centers are partners in the LISS. These organizations also have historical and ongoing work with other partners in the LISS study region. Although historically the focus of LISS has been on water quality issues, a “Sustainable and Resilient...

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 corridor, have been impacted by and remain extremely sensitive to acidic deposition. Ridgetop soils that are often low in calcium make the ecosystems of the AT more sensitive to acidic deposition than other ecosystems. Furthermore, upper elevations tend to receive the highest levels of deposition. In areas along the AT, such...

Environmental Sensitivity Index (ESI) maps provide a concise summary of coastal resources that are at risk if an oil or chemical spill occurs nearby. Examples of at-risk resources include biological resources (such as shorebirds and mussel beds), sensitive shorelines (such as marshes and coastal wetlands), and human-use resources (such as public beaches and parks, as well as areas that could be used for access and staging in a spill response). Environmental Sensitivity Index maps are used by incident response managers from a wide range of federal and state agencies to guide decisions about where and how to prioritize emergency response and restoration activities after an oil or chemical spill. The National Oceanic...
Summary: This study aims to do a thorough analysis of trends in peak streamflows on Long Island. Reliable information about the magnitude and frequency of floods is essential for flood insurance studies, flood-plain management, and the design of transportation and water-conveyance infrastructure, such as roads, bridges, culverts, dams, and levees. Federal, State, regional, and local officials need peak flow information to effectively plan and manage land use and water resources, protect lives and property in flood-prone areas, and determine flood-insurance rates, particularly in densely populated urban areas. Long Island is a regional economic driver which has experienced public health and safety issues due to extreme...

Introduction Detailed mapping of stratified glacial deposits in eastern Broome and southeastern Chenango Counties, New York is a study in the cooperative Detailed Aquifer Mapping Program between the US Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The aim of the program is to map glacial aquifers in New York State at a scale of 1:24,000. This information is used by NYSDEC Division of Water and others for delineation of groundwater contributing areas, assessing potential threats to aquifers from both point and non-point sources, responding to contamination from spills or leaks from underground storage facilities, and providing information to assess the need...

Approach: The spatial variability of dissolved oxygen in the Arthur Kill will be characterized through a single 24-hour day of boat-based spatial surveying using a combination of high-resolution mapping and vertical profiles in late summer 2023. Staff from USGS New York will conduct synoptic mapping by collecting near-surface continuous water-quality data from a boat. This team will collect data in a zig-zag pattern for the entire length of the river and will repeat this multiple times throughout the 24-hour period. Staff from USGS New Jersey will be in a second boat and focused on capturing vertical profiles along the length of the river to understand dissolved oxygen variability at depth. Dissolved oxygen will...
