Problem - The purpose of this project is to create a watershed GIS (Geographic Information System) to support the comprehensive cleanup and restoration of Onondaga Lake that is underway. A GIS is a computer system capable of capturing, storing, analyzing, and displaying geographically referenced information; that is, data identified according to location. Given the broad scope of the Onondaga Lake Partnership's (OLP) mission, a GIS is a powerful tool that can organize, store, and share information pertinent to the management of the natural resources of the Onondaga Lake watershed. The OLP GIS will be used for land use planning, resource management, scientific monitoring, and data presentation. The project has...

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 place since the mid-1970’s, and various USGS sources, and supplement this information with more recent seasonal and annual hydrologic technical assistance will be provided to the Suffolk County Water Authority (SCWA) to help them produce an easy to understand annual report that will provide a snapshot of the state of Long Island's...

Problem – Currently, swim advisories or closings are issued by beach managers based on standards for concentrations of bacterial indicators such as Escherichia coli (E. coli). Standard culture methods for these bacteria take at least 18-24 hours before results are available. At most Great Lakes beaches, the beach is posted with an advisory or closing or is determined to be acceptable for swimming on the basis of the previous day’s E. coli concentration. Sanitary conditions may change overnight and even throughout the day (Boehm and others, 2002) making decisions made from previous days information incorrect. Because of this time-lag issue, water-resource managers are seeking solutions that provide near real-time...

Background: A sequence of gently dipping carbonate bedrock - the Bertie Formation, Akron Dolostone, and Onondaga Limestone crop out along a 2- to5-mile wide band in western and central New York. These bedrock units trend east-west for 250 miles across the State and form extensive carbonate-bedrock aquifers which transmit and yield water from solution-enlarged fractures, bedding planes, and other openings (Olcott, 1995). Bedding planes or sub-horizontal fractures typically are the most enlarged and important water conduits. Karstic features such as sinkholes, swallets, solution channels, and caverns can locally transmit large amounts of surface water into the ground where the groundwater can move quickly and over...

Problem - The major hydrogeologic units of Long Island, New York, have been delineated as part of the islandwide mapping effort of Smolensky, Buxton, and Shernoff that was published in 1989 as U.S. Geological Survey (USGS) Hydrologic Atlas (HA) 709. Concern about local details in the hydrogeologic framework that may not be represented in HA-709 has led the USGS, in cooperation with the U.S. Environmental Protection Agency (EPA), to assess the hydrogeology of the Long Island area so ground-water-flow modeling planned by EPA can more fully reflect local hydrogeologic conditions. Objectives - The primary objective of this project is to construct geographic information system (GIS) datasets of the altitudes of the...

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...

Summary: Extreme flooding can threaten life and property in flood-prone areas, as well as cause damage to critical infrastructure along roadways and canals. The effective management of these areas, and appropriate design of structures along rivers and streams, relies on understanding the magnitude and frequency of floods at gaged locations, and the ability to estimate these data at ungaged streams. Peak flow analysis and development of regional regression equations to estimate peak flow frequency and magnitude for New York have not been updated using any new data collected since 1999 (Lumia, 2006). As more data and newer technology have become available there is a need to update these data. The updated regression...

Problem - Since the 1980s, the U.S. Geological Survey (USGS) has mapped over 30 sand and gravel aquifers in upstate New York at the 1:24,000-scale. These mapped aquifers include both the primary and many of the principal aquifers as designated by the New York State Department of Environmental Conservation. Although the 1:24,000-scale maps are valuable in their present form, their usefulness is limited because the important features on the maps, namely aquifer boundaries and the surficial geology, are not available as digital geographic information system (GIS) datasets. Objectives - To maximize the usefulness of the aquifer maps, GIS datasets of the 1:24,000-scale aquifer maps will be developed. To further increase...

PROBLEM There are more than 60 organizations and agencies collecting water-quality data on Long Island. The types of database management that are used to store and archive regulatory and non-regulatory data vary from paper forms to spreadsheets to State and Federal databases, and there is minimal communication between these systems. As a result, those interested in analyzing data may be unaware of what data exist and how those data can be obtained without a Freedom of Information Law request. A unified data sharing system that provides multiple levels of sensitive and non-sensitive data storage and dissemination is needed. This system should link the various databases and interact through web services to provide...

Problem - The New York State Departments of Environmental Conservation (NYSDEC) and Health (NYSDOH) are concerned about Problem - The New York State Departments of Environmental Conservation (NYSDEC) and Health (NYSDOH) are concerned about ground-water contamination in the carbonate-bedrock aquifers, especially relating to the inadvertent introduction of volatile organic compounds (VOCs) and manure to these aquifers. Groundwater can flow very quickly with minimal filtration or adsorption through solution-widened fractures in carbonate-bedrock aquifers. Therefore, large amounts of water and associated contaminants can move long distances, sometimes in short periods of time, and affect large areas. If these underground...

Problem – Flooding is an annual problem along Egypt Creek in Dryden. Increased runoff from expanding development, sediment clogged channels, and undersized culverts that cannot convey increased flows contribute to the problem. Flood maps for extreme floods are available through the effective FEMA flood insurance study (FEMA, 1978), but these maps, which became effective in 1979, are considered no longer valid by the Village of Dryden owing to development in the basin, which presumably has increased runoff and, in at least one instance, encroached on the floodplain. In addition, similar data for lower, intermediate, and higher floods are non-existent. Emergency responders and the public would benefit from a series...

Problem - Geomorphologic techniques for stream channel and bank restoration are fast becoming the techniques of choice among federal, state, county, and local agencies to reduce suspended sediment loads, reduce flood damage, improve aquatic habitat, and generally stabilize stream channels. One reason for this upswing in use is that appropriate application of these techniques has been shown to reduce the need for repetitive visits to a reach to remove sediments or repair stream banks, and thus reduce long-term channel maintenance expenses. Geomorphologic restoration projects require data that define what a stable stream channel should look like in a given region. Regional hydrologic curves and regional channel-geomorphologic...

Problem - The Town of Caroline needs geohydrologic data in two major valley-fill aquifers within the town in order for planners to develop a strategy to manage and protect their water resources. Interest in the interaction between ground water and surface water has increased in recent years as a result of widespread concerns related to water supply. The need to better understand how the development of one water resource affects another will increase as development in Tompkins County intensifies. Upper Sixmile Creek/West Branch Owego Creeks valleys and Lower Sixmile Creek/Willseyville Creek valleys in the Town of Caroline were selected to be studied because they are undergoing increasing development; and most people...

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...
