Problem - The entire Tug Hill glacial aquifer is a 47-mile-long, crescent-shaped mixture of glacial deposits of predominantly sand and gravel on the western side of the Tug Hill Plateau in Jefferson, Oswego, and Oneida Counties in north central New York. The Tug Hill aquifer can be divided into three parts (northern, central, and southern) based on geohydrological setting, depositional history, and type of glacial deposits (fig. 1). In this study, the name “Tug Hill glacial aquifer” refers only to the 29-mi-long northern and central parts of the Tug Hill aquifer. (The southern part was not included in this investigation.) For this study, the division between the northern and central parts of the aquifer was placed...

Problem : Occurrence and persistence of emerging contaminants in groundwater flow in Suffolk County, New York Objectives: This project will monitor groundwater from selected SCWA supply wells for compounds indicative of anthropogenic sources, which are of increasing public concern. Approach: Groundwater-flow information, well-construction details, and distance from treated wastewater (including municipal and industrial) discharge areas will be used to select 12 wells that are along the paths of groundwater flow from discharge sites. Groundwater samples will be analyzed for roughly 100 common organic contaminants—including pharmaceuticals, hormones, and wastewater indicators—that could potentially pass through...

Problem The groundwater supply of Nassau and Suffolk Counties is prone to contamination from past and current land uses, including practices related to agriculture, industry, and residential development, 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 on-site disposal of residential wastewater and industrial processes. The centralized distribution of water through purveyors to most residents provides them with a reliable source of potable water that is consistently monitored at the wellhead. However, increased...

Problem Almost 1900 public, private, and commercial waste-water treatment plants (WWTPs), many located upstream of drinking water intakes or within tributaries to water-supply reservoirs, are permitted to release effluents into surface- or ground-waters across New York State. More than 150 facilities have New York State SPEDES permits to discharge waste waters in the New York City East of Hudson and West of Hudson Water Supply Watersheds (NYC Watersheds), which provide drinking water to more than nine million people in and around New York City. Some common waste water treatment plant (WWTP) contaminants (e.g., polycyclic musks, alkylphenols, and estradiol) can cause estrogenic or androgenic changes in the reproductive...
Background The Long Island-New Jersey (LINJ) coastal drainages NAWQA study is one of the 1994 set and is coordinated from our West Trenton, NJ office. Tasks for the first two years, 1994-95, included staffing, developing a liaison process, analyzing existing data, and designing a data collection program that started in 1996. These planning activities lead to the study design for 3 years of intensive data collection in 1996-98. The intensive efforts includes multi-scale study approaches to collect samples of water, suspended and bed sediment, biologic tissues, and aquatic communities. The LINJ NAWQA study is scheduled to enter a low-intensity phase of monitoring and report writing in 1999 and return to another...

Background The U.S. Geological Survey (USGS), in cooperation with the Village of Patchogue and the New York Department of State, collected water-quality samples from 10 shallow wells within the village to document the effects of onsite wastewater disposal on groundwater discharging into the Patchogue River. The onsite disposal of wastewater within the Patchogue River basin - a riverine estuary that discharges into Great South Bay, Suffolk County, Long Island, NY - has adversely affected water quality and aquatic habitats within both the tidal and non-tidal portions of the river. Of particular concern are increased loads of nutrients (nitrate, nitrite, ammonia, and phosphorus) to the shallow groundwater system which...

A major focus of the NAWQA Program in its second decade (2002-2013) is on regional- and national-scale assessments of groundwater-quality status and trends in principal aquifers. The U.S. Geological Survey Office of Groundwater has identified 62 principal aquifers in the U.S. (U.S. Geological Survey, 2003). About 1/3 of the Nation's principal aquifers are the focus of water-quality assessments at the regional scale by NAWQA. The NAWQA framework for principal aquifer assessments considers the physical setting of the aquifer, in addition to its susceptibility and vulnerability to contamination.

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...

Problem Perchlorate detected in a shallow supply well within the southern portion of the Locust Valley Water District (LVWD) has prompted interest in determining the possible existence of a deeper confined aquifer (North Shore Aquifer) that may be protected from shallow contamination (fig. 1). Previous USGS studies in this area indicate the northern part of Nassau County has a complex hydrogeologic framework (Stumm and others, 2004). A previously mapped buried glacial valley may extend and be present at this location. If such a buried valley exists, all Cretaceous age deposits (Magothy aquifer, Raritan clay, and Lloyd aquifer) may have been eroded and Pleistocene-aged deposits including the North Shore aquifer...
Problem Previous hydrologic studies have indicated that there may be sufficient water resources underlying Richmond, New York, and Bronx Counties for use as a supplemental water supply by the New York City Department of Environmental Protection (NYCDEP) in times of a drought or other water shortage. Unfortunately, comprehensive data on the quantity and quality of the Counties' water resources are not available to make an accurate assessment. In order to evaluate the availability and suitability of these resources, representative and timely data on the ground-water and surface-water resources of these three Counties are needed. Objectives The primary objective is to develop, operate, and maintain long-term monitoring...
