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...

Problem - In August 2000, eleven sites were sampled from 9 streams within the Croton watershed for pharmaceuticals and other organic compounds associated with wastewater as part of a national study of these compounds in streams receiving wastewater discharges. Results from the national study indicated that streams in the Croton Reservoir downstream of sewage treatment plants had concentrations of target compounds. Detected compounds included pharmaceuticals, detergent degradates, insecticides, caffeine, and other organic compounds (Kolpin and others, 2002). The results indicate that these compounds are commonly present in streams below wastewater treatment plants (WWTPs). Many of these compounds have not been...
Introduction Ongoing efforts to improve the health of New York's South Shore Estuary Reserve (SSER) require continuously recorded water-quality data to understand the short-term effects of stormwater runoff and other pollution sources. To document the diel and tidal variability of water quality in the western bays of the SSER, the USGS monitors select physical and chemical parameters at two sites within the SSER. One site, station 01310740 on Reynolds Channel at Point Lookout, is near the estuary mouth and operated in cooperation with the New York State Department of Environmental Conservation (NYSDEC) and Town of Hempstead Department of Conservation & Waterways. The second, station 01311143...

In 1979, the U.S. Geological Survey (USGS) entered into a cooperative agreement with Monroe County (MC), which, over the span of more than three decades, has resulted in more than 30 reports that have summarized flow and water-quality data at sites in Monroe County and have presented the results of investigations of particular water-related issues that existed in the County. The collaborative relationship between Monroe County and the USGS entails: - USGS training and oversight of MC personnel to conduct site visits and measure streamflow and collect water samples at monitoring sites; - analyses of water samples by MC in a certified environmental laboratory that routinely participates in a USGS quality-control program...

Background In order to help identify sources of high Enterococci concentrations identified by the Village of East Hampton and the Surfrider Foundation’s water-quality sampling upstream of Hook Pond, surface water and groundwater samples will be collected and analyzed for F+-specific coliphage, bacteroides, Enterococci and fecal coliform, and nitrogen isotopes. Potential sources of pathogens include waterfowl, failing onsite wastewater disposal systems, and stormwater runoff. F+-specific colipahge (Griffin and others, 2000) and bacteroides (Stoeckel, 2005) analyses are sensitive microbial source tracking methods that can discern human, mammal, and bird sources. Nitrogen isotopes are used in conjunction with concentrations...
Problem - The Onondaga Lake Partnership (OLP) is committed to improving the water quality of Onondaga Lake. Onondaga County Soil and Water Conservation District (SWCD) has promoted best-management practices to decrease loads of nutrients and sediment from agricultural lands. Onondaga County Department of Water Environment Protection has abated many of the outflows from combined sanitary-and-storm sewers in the city of Syracuse and has upgraded treatment capabilities for removal of nutrients in effluent from the county's Metropolitan waste-water-treatment plant. These measures have fallen short of target levels of phosphorus and nitrogen loadings to Onondaga Lake because of inputs from nonpoint sources of pollution....

Problem - Urbanization of the 150-square-mile Irondequoit Creek basin in Monroe and Ontario Counties, N.Y., continues to spread southward and eastward from the City of Rochester. Conversion of forested land to other uses over the past 40 years has increased to the extent that more than 50 percent of the basin is now developed. This expansion has increased flooding and impaired stream-water quality in the northern (downstream) half of the basin. A precipitation-runoff model of the Irondequoit Creek basin could be used as a management tool by water-resources managers to better understand the hydrology of the basin, permit simulation of planned or hypothetical land-use changes, evaluate the adverse effects of future...

Problem The quality of surface water has important effects on human and ecological health. Surface water is an important drinking water source and is used for swimming, fishing, and recreation, and the quality of surface water can have profound effects on the health, diversity, and resilience of ecological communities. The New York State Department of Environmental Conservation (NYSDEC) is tasked by the U.S. Environmental Protection Agency (USEPA) to monitor ambient water quality of the State. The NYSDEC is also tasked to develop Total Maximum Daily Loads (TMDLs) for state waters that fail to meet their intended use. A critical first step in maintaining high quality of surface-water is assessment of existing...

PROBLEM Hook Pond, an 83-acre freshwater pond in East Hampton, N.Y., has historically shown indications of impaired water quality. Impairments in this shallow pond include elevated nutrient concentrations and low dissolved oxygen concentrations in bottom waters as a result of current and historical land-use practices (Lombardo, 2015). Recent (2016) harmful algal blooms in Hook Pond and other eastern Long Island freshwater bodies have spurred local concerns about the loading of nutrients from septic systems to groundwater (and ultimately to surface water), and land-use practices that contribute to contaminated stormwater runoff. To properly evaluate the basic ecological health of the pond, an understanding of the...
The distribution of mercury (Hg) and sites of greatest Hg methylation are poorly understood in Catskill Mountain watersheds. Although concentrations of Hg in the water column are low, high concentrations of Hg in smallmouth bass and walleye have led to consumption advisories in most large New York City reservoirs in the Catskill Mountains. Mercury in natural waters can exist in many forms, including gaseous elemental mercury (Hg0), dissolved and particulate inorganic forms (Hg(II)), and dissolved and particulate methylmercury (MeHg). Most Hg in living organisms is MeHg, a highly neurotoxic form that bioaccumulates in aquatic food webs. The production of MeHg by methylation of inorganic Hg in the environment...
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...

Problem Samples were collected from 10 Key Point sites in the New York City Reservoir system as part of the cooperative USGS-New York State Department of Environmental Conservation (NYSDEC) statewide pesticide monitoring project ( Phillips and others, 2000). Ten pesticides were detected in the key-point samples collected between January 1999 and September 2000 - the herbicides atrazine, metolachlor, simazine and prometon, the herbicide degradates deethylatrazine, hydroxyatrazine, alachlor ethanesulfonic acid (ESA), metolachlor ESA, and metolachlor oxanilic acid (OA), and the insecticide diazinon. Concentrations for most of these detections were generally low (between 0.001 and 0.05 ug/L), with the exception of...
