Long Island Water Suitability
Groundwater quality may be affected by natural and human factors (Johnston, 1988). Although the vulnerability of groundwater to contamination from the land surface is influenced by many factors, the degree of aquifer confinement, the depth of the well, and the surrounding land use are primary key factors that influence shallow groundwater quality.
Long Island Water Suitability Case Studies
A collection of studies that focused on the quality of groundwater and surface water, are presented in this section. The reports associated with these areas of water quality concerns are linked as an online source for further reading.
Long Island Groundwater System Potential Hazards
Hazards which may impact the ground water system adversely are presented in this web page. The impacts of these hazards are only shown here as a topic for further discussion and may need to be investigated with further details.
State of the Aquifer, Long Island, New York
Groundwater is among the Nation's most important natural resources. Nationwide it provides half of our drinking water and is essential to the vitality of agriculture and industry, as well as to the health of rivers, wetlands, and estuaries throughout the country. On Long Island groundwater is the sole source of fresh water for over 2.6 million people.
Groundwater Monitoring on Long Island, New York and the Five Boroughs of New York City
The groundwater data-collection network of the USGS New York Water Science Center, Coram Program Office encompasses data collection from approximately 600 groundwater-monitoring wells on Long Island and in the five boroughs of New York City. Data from these stations are collected in varying frequencies to supply our cooperators, stakeholders, and the public with mission critical information.
Delineation of the Saltwater-Freshwater Interface at Selected Well Locations in the Town of Riverhead, NY
Problem The Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-suppl

New York Water Science Center Data Program
Objective: The USGS New York Water Science Center (NYWSC) works with other Federal agencies as well as with State, municipal, and tribal agencies to provide research and data about water-related issues. Relevance and Impact: The NYWSC leads the scientific and water-resources management communities by providing high-quality, timely, and unbiased scientific data, reports, and other information that
Groundwater-level Monitoring for Characterization of Hydraulic Connections in the Basal Sand & Gravel Aquifer, Hoosic River Valley, Hoosick Falls, New York
Hydrogeologic characterization of the basal sand and gravel aquifer in the Hoosic River valley in Hoosick Falls, New York is important for determination of sources, extent, and future migration of PFOA groundwater contamination; evaluation of potential remedial actions; and appraisal of alternative groundwater supplies. Variations in the current pumping stresses and a planned 72-hour aquifer t
Assessment of stormwater control measures at the Niagara River Greenway Project, Buffalo, New York
Background The proposed study will examine any existing data from the monitoring wells, weather station, and flow through the storm sewer system (supplied by Buffalo Sewer Authority) to determine the dynamics of the system during storm events. Further analysis using all available information is needed to fully understand the relationship of events to the implementation of Green Infrastructure sto
Development of a Ground-Water Flow Model for the Manhasset Neck Peninsula, Nassau County, New York
Problem The ground-water flow system underlying the Manhasset Neck Peninsula, which provides potable water to the local population, consists of a complex assemblage of Pleistocene- and Cretaceous-age sediments that form five aquifers and at least two confining units. Recent hydrogeologic mapping in Manhasset Neck indicates significant glacial erosion of the Magothy aquifer, Raritan Clay, and Llo
Simulation of Zones of Groundwater Contribution to Three Well Fields Southwest Portion of the Naval Weapons Industrial Reserve Plant, Bethpage, New York
Summary The U. S. Geological Survey (USGS) will conduct simulations using existing aquifer data, including geologic logs from vertical profile borings (VPBs) and well installations, water levels, and pump test data available from the water districts for these production wells. Subsequently USGS will incorporate data from a groundwater pump test and additional data from new VPBs and monitoring w
