Groundwater and Streamflow Information

Groundwater and surface water are among the Nation’s most important natural resources. The USGS provides unbiased, timely, and relevant information, studies, and data about water resources of the Nation. The NYWSC maintains a network of more than 300 surface water and 650 groundwater monitoring stations across New York State; over the years, the USGS has collected water-resources data at approximately 1.5 million sites in all 50 States, the District of Columbia, Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands. The data collected at the various sites are synthesized in State-level, interstate, and international studies to evaluate resources not only in one State but also other States and countries that might be affected or may influence the condition of surface water and groundwater. The data collected are used in studies of water supplies, groundwater contamination, flooding, water stored in ice and the oceans, and the effects of climate and land use change and manmade influences.

Geohydrology of the Unconsolidated Aquifer in Enfield Creek Valley, Town of Enfield, Tompkins County, New York

PROBLEM The unconsolidated aquifer in Enfield Creek Valley (fig. 1) was mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that needs to be studied in more detail. Well records in Enfield Creek valley indicate that the northern part of Enfield Creek valley contains sand and gravel deposits which may be under unconfined conditions in some areas, con...

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 19...

Hurricane Sandy -- Science to support coastal resilience

Coastal Hydrology and Storm Surge Storm-surge is one of the most powerful and destructive elements of major storm events. Excessively high tides associated with storms can flood and inundate coastal areas, often moving sediment and altering coastal landscapes and drainages. USGS provides critical expertise in measuring storm surge and assessing conditions both before and after the storm....

Development of a Coordinated Water Resources Monitoring Strategy for the South Shore Estuary Reserve, Long Island NY

The U.S. Geological Survey (USGS) is collaborating with the New York Department of State (NYDOS) Office of Planning and Development to prepare a new Long Island South Shore Estuary Reserve (SSER) Coordinated Water Resources Monitoring Strategy (CWRMS). Since 2000, when the last CWRMS was published, numerous research projects and studies are demonstrating several new threats to the ecologic...

Detailed Aquifer Mapping in Eastern Orange County –The Ramapo River –Woodbury Creek Valley

Introduction Detailed mapping of the glacial aquifer within the Ramapo River and Woodbury Creek Valley in Eastern Orange County is the latest 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 scal...

Detection and Quantification of Oxygenated Polycyclic Aromatic Hydrocarbons (oxy-PAHs) in Groundwater Near the Former Manufactured Gas Plant in Bay Shore, N.Y.

Introduction As a result of storage and disposal practices at a former Manufactured Gas Plant, or MGP, in Bay Shore, NY, a variety of polycyclic aromatic hydrocarbons (PAHs) have been detected at high concentrations in the surficial, upper glacial aquifer of Long Island. Levels of PAHs initially detected over 10 years ago were in the parts-per-thousand range within a groundwater contaminant...

Water Quality Data for Tributaries to Lake Ontario in New York-- Great Lakes Restoration Initiative, Lakewide Impairment Study

Lake Ontario is the easternmost Great Lake and has a direct drainage area of 24,720 square miles (mi2)(excluding the Niagara River and upper Great Lakes watershed), and is bounded by the Canadian Province of Ontario to the north and west and New York State to the south and east. Lake Ontario receives its primary inflow from the watersheds of the upper Great Lakes through the Niagara River...

State of the Aquifer, Long Island, New York

Background In recent years, more and more people have become concerned about Long Island's supply of freshwater. Currently, there is no comprehensive, island-wide resource that summarizes recent U.S. Geological Survey (USGS) research related to the Island's aquifer system. A webpage will be developed by the USGS that will compile published data from the hydrologic-surveillance program, in p...

305b Ambient Groundwater Quality Monitoring in New York

Introduction Relatively little data describing the quality of groundwater in New York State exists, yet groundwater is used as a source of drinking water by approximately one quarter of the population of the state. The objective of the 305(b) groundwater quality monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate Ne...

Estimating Loading Above and Below Agricultural Best Management Practices (BMPs) and Combined Animal Feeding Operations (CAFOs) in the Genesee River Watershed

The current information available for the Genesee River and watershed is insufficient to assess if the Beneficial Use Impairment (BUI) delisting criteria for the Rochester Embayment Area of Concern (AOC) can or have been met. With on-going and future projects that are implementing best practices to control soil erosion and the reduction of nutrients that reach the Rochester Embayment, the...

Delineation of the Freshwater-Saltwater Interface at Selected Public-Supply Wells Using Advanced Surface and Borehole Geophysical Techniques, in Eastern Suffolk County, New York

The combination of a complex hydrogeologic framework, narrow land masses surrounded by saltwater, and extensive ground-water public-supply pumpage has produced localized areas of elevated chloride concentrations in ground water. This project uses advanced surface and borehole geophysical methods to determine the extent of saltwater intrusion and road-salt plumes at selected sites in eastern...
