Summary The Long-Term Monitoring Network (LTM) is funded by the U.S. Environmental Protection Agency (EPA) to monitor trends in surface water quality by nesting a few intensively-monitored stations within a network of more numerous but less frequently sampled stations. The intensively-monitored stations have provided monthly discharge and water-quality data at 6 locations across the country since 1983. Continuous discharge and storm water quality sampling were added to these stations in the late 1980’s. One of the major objectives of the Clean Air Act Amendments (CAAA) was to establish a network of stations for long-term monitoring of surface-water quality and to determine its relation to changes in atmospheric...

A. BACKGROUND Aquatic macroinvertebrates, such as dragonfly larvae or crayfish have great potential for Mercury (Hg) monitoring, both as indicator organisms (or "sentinels'), and to provide critical information on Hg in lower food webs to assist in interpreting fish Hg levels. Despite these advantages, macroinvertebrates are not widely used in Hg monitoring because of the current need to directly analyze macoinvertebrate tissue for methyl-mercury (MeHg), at much greater expense than analyzing for total Hg (THg) (i.e. as a surrogate for MeHg), as with fish tissue. This is because the ratio of MeHg to THg in macroinvertebrates exhibits large taxonomic, spatial, and temporal variation, and there is no clear...

Summary The Hydrologic Benchmark Network (HBN) consists of 37 watersheds that provide long-term measurements of streamflow and water quality in areas that are minimally affected by human activities. In 2011 measurements of aquatic biology and soil chemistry were added to the network. All of these data are used to study long-term trends in surface water flow, water chemistry, aquatic biology, and soil chemistry and as a benchmark against which to compare changes in flow and chemistry in developed watersheds. In 1962, Luna B. Leopold, then Chief Hydrologist of the U.S. Geological Survey (USGS), proposed the establishment of a network of “hydrologic benchmarks” on the nation’s rivers (Leopold, 1962). The main purpose...
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 - Several supply wells in Oswego County were evaluated by the USGS in 1999 by using stable oxygen and hydrogen isotopes and chlorofluorocarbon (CFC) age dating techniques. For two municipal well sites (the Villages of Sandy Creek and Lacona, and the Village of Pulaski) that tap a shallow, unconfined aquifer (typically 20-50 ft thick) there were significant discrepancies between ground-water recharge ages determined by chemical data and those determined by ground-water-flow models developed by independent studies. The significant discrepancies between the times of travel of ground water as determined by numerical ground-water-flow modeling and geochemical dating techniques in Oswego County need to be understood...

Monitoring of lake chemistry in the western Adirondack region has indicated reductions in the acidity of these lakes during the past two decades. However, lakes are not always reliable indicators of streams and soils. Uncertainty remains regarding the recovery potential of surface waters and the effects of acidic deposition on soils. Furthermore, nitrogen, long considered a growth-limiting nutrient for northern temperate forests, is likely to be available in excess of that needed by Adirondack forest ecosystems as a result of acidic deposition. In this region, excess nitrogen in the soil leads to acidification of soils and surface waters. Calcium, important for acid neutralization, is also an important nutrient,...
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...

Background: The waters of the Mohawk River basin are inhabited by one of the richest fish communities on the East Coast. The American Eel, Anguilla rostrata, is a unique member of this community, exhibiting a catadramous (maturing in fresh water and spawning in salt water) life history. Like many migratory fish, the American Eel has suffered a general decline across the East Coast largely attributed to barriers to migration and habitat degradation and other anthropogenic disturbances to the point that the species has been recommended for listing under the Endangered Species Act twice in the past ten years A recent study by Machut et al. (2007) and the implementation of a NYSDEC-initiated citizen science juvenile...

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...
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...

Description of Study The objective of this study was to define specific conductance in stream water under low streamflow conditions in Central New York. The study area covers parts of six counties in the Southern Tier region of New York State (fig. 1). This survey covered a range of watershed areas and land use types, and specifically targeted low-flow periods during the summer as the flow would be mostly derived from groundwater discharge at this time and represents the upper limit of conductance that can currently be expected. This study was funded by the New York State Department of Environmental Conservation. Methods The network of sites sampled was created using ARCMAP software. Over 280 sites were selected...

A USGS biologist prepares to collect a sediment sample using a petit ponar dredge. Background:The Niagara River forms the boundary between the United States and Canada and was designated as a binational Area of Concern (AOC) in 1987 because past industrial discharges and hazardous waste sites had caused extensive degradation of aquatic habitats. Within the United States (eastern) portion of the AOC, seven Beneficial Use Impairments (BUIs) have been identified, including the degradation of the “benthos”, or the benthic macroinvertebrate community. Past assessments of macroinvertebrate community structure and sediment toxicity, which indicated that macroinvertebrate communities were adversely affected by contaminated...
Problem - The Village of Pulaski in Oswego County, N.Y., obtains its water supply from groundwater that drains under gravity from an unconfined aquifer into three shallow dug wells. The well field is in an area where groundwater discharges to springs along the west edge of the Tug Hill Aquifer, which is comprised of beach and kame deposits of sand and gravel. A numerical groundwater model was constructed previously to simulate groundwater conditions in part of the Tug Hill Aquifer near the Pulaski well field. The modeling work was part of a wellhead protection study to develop a plan to protect the groundwater resources of the Village of Pulaski's public water-supply system. In addition, the USGS, in cooperation...

Background The U.S. Geological Survey (USGS) has characterized fractures, foliation, and fractured-rock groundwater flow penetrated by test boreholes in crystalline bedrock underlying Manhattan Island, New York County, New York since 1998. New test boreholes will be drilled on Roosevelt Island in New York County for a Cornell University geothermal test project. Cornell University is partnering with the USGS in a cooperative program to use advanced borehole geophysical methods to characterize the fractured-rock groundwater flow system on the southern end of Roosevelt Island, and compare it to the flow system on nearby Manhattan Island. The USGS will assess the hydrogeology of the area and determine the strike and...

Background: The USGS propose a collaborative investigation with the NYSDEC to evaluate the current condition of benthic macroinvertebrate communities and toxicity of bed sediments in the Eighteenmile Creek Area of Concern (AOC). Sediment-toxicity data provided by the USGS and benthic-community data provided by the NYSDEC from inside the AOC will be compared to similar data from non-AOC sites in Eighteenmile Creek or nearby reference streams (of comparable drainage areas) to determine if the benthos-BUI (Beneficial-Use Impairment) designation is appropriate or if the BUI could be removed in Eighteenmile Creek. The remainder of this pre-proposal addresses only the direct USGS (sediment toxicity assessment) contribution...
PROBLEM Alley Creek, a tributary to Little Neck Bay (Queens County, New York; figure 1) has been designated as impaired by the New York State Department of Environmental Conservation (NYS DEC) for primary and secondary contact and included on the 303(d) Impaired Waterways for pathogens related to combined sewer overflow contributions. The New York City Department of Environmental Protection (NYC DEP) and New York City Parks & Recreation have developed a long-term control plan (2014) and a watershed management plan (2015), respectively, to improve water quality and ecosystem health. Point and non-point sources of pathogens are implicated, including stormwater and combined-sewer outfalls, groundwater seepage, and...
