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...
Introduction Detailed mapping of the valley-fill aquifer within the Owasco Inlet valley and adjacent tributary valleys in Cayuga County (Towns of Moravia and Locke) and Tompkins County (Town of Groton) 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 sand and gravel aquifers in New York State at a scale of 1:24,000. This information is used by NYSDEC Division of Water and others to delineate groundwater contributing areas, assess potential threats to aquifers from both point and non-point sources, respond to contamination from spills or leaks...

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...

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 Ambient Groundwater Quality Monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate New York, and is an ongoing cooperative project between the U.S. Geological Survey (USGS) and New York State Department of Environmental Conservation (NYSDEC). The project began in 2002 with a pilot study in the Mohawk River Basin and another in 2003 in the Chemung River Basin. Sampling completed in 2018 represented the conclusion...

Background: The New York State Departments of Environmental Conservation (NYS DEC) and Health (NYS DOH) are concerned about groundwater contamination in the carbonate-bedrock aquifers in New York, especially relating to the unintended introduction of volatile organic compounds (VOCs) and liquid manure to these aquifers. These carbonate rocks form extensive aquifers that transmit, and can yield, water from solution-enlarged fractures, bedding planes, and other openings (Olcott, 1995). Groundwater contamination from liquid manure application (fecal coliform bacteria [E. coli] and nitrate) has been on the increase over the past decade as these incidents have been reported to the NYS DEC. Nitrate is highly water-soluble...
