Introduction Mosquitoes are the principle vector of the West Nile Virus (WNV) which causes infections in humans and animals and has emerged as a public health threat throughout Long Island, NY. The WNV was first detected among birds and mosquitoes by the Suffolk County Department of Health Services (SCDHS) in 2000. In response to the public health concern, the USGS in cooperation with the SCDHS, began a 3-year study in 2002 to sample surface waters in selected wetlands for insecticides which were sprayed seasonally from a truck or helicopter as part of the county's vector-control program. These insecticides include Altosid (methoprene) and Scourge [1:3 ratio of resmethrin and piperonyl butoxide (PBO)]. Methoprene...
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...

Near-surface geophysical data from within the Bonita Peak Mining District in Silverton, Colorado, USA are presented. These data were collected in 2019. The data include fiber optic distributed temperature sensing (FO-DTS) and frequency domain electromagnetic induction (FDEM) data collected in and around roughly 1 km reaches of Cement Creek and California Gulch. Additional data, including ground penetrating radar (GPR) and self potential (SP), were gathered from a peatland that intercepts acid mine drainage from Mogul Mine into Cement Creek. The peatland is located off the eastern bank of Cement Creek in the northern portion of the reach surveyed with FO-DTS and FDEM. In 2021, an FO-DTS, FDEM, and magnetometer (MAG)...

Purpose and Scope The Natural Resources Department of the Bad River Band of Lake Superior Chippewa, Odanah, Wisconsin has requested assistance with compiling existing mercury (Hg) concentration data from measurements in a variety of environmental media in an effort to evaluate risks to ecosystem and human health and to identify key data gaps that could be addressed through future sampling. These data include Hg concentrations in fish, frogs, otters, birds, wild rice, the atmosphere, surface water, and sediment. The purpose of this proposed study is to compile existing Hg data collected by the Bad River Band of Lake Superior Chippewa, evaluate the potential risks to humans and to local ecosystems, and to recommend...

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...

Background: Rainbow Trout (Oncorhynchus mykiss) have thrived in the Esopus Creek since their introduction in the 1880s. The construction of the Ashokan Reservoir in 1915 changed the fishery by providing a stable lentic environment where adult trout could grow large and find refuge during periods when stream conditions become stressful. Although many adult Rainbow Trout spend time in the reservoir, it is believed that spawning occurs almost exclusively in the tributaries; most notably the Upper Esopus and its tributaries. Thus, the health of individual Rainbow Trout and the size of their spawning runs out of the Reservoir not only regulate the species’ future population in the reservoir, but also the population...
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.

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...
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...

This child item contains fiber-optic distributed temperature sensing (FO-DTS) data collected along the streambed interface of two streams named Cement Creek and California Gulch Creek, as well as the Animas River, located near Silverton Colorado. The FO-DTS method utilizes the temperature-dependent backscatter of light pulses emitted along armored fiber-optic cables to evaluate temperature at discrete linear sampling locations. For these deployments a Salixa XT-DTS control unit (Salixa Ltd, Hertfordshire, UK) was used, and measurements were made over several day increments at 0.508 m linear resolution along the streambed interface. Specific locations for collected data are located within the data files, and additional...
The National Crude Oil Spill Fate and Natural Attenuation Research Site is located near Bemidji, MN, USA. A high-pressure oil pipeline ruptured in 1979 releasing ~1.7 million liters of light crude oil, which sprayed over an area of ~6500 square meters and collected in topographic depressions. Approximately 75% of the spilled oil was recovered. Much of the remainder reached the water table, where it is distributed into three residual oil bodies (the north, middle, and south oil pools). Groundwater flows east-northeast toward a small lake roughly 300 m downgradient from the original spill site. Secondary reactions of sediments with byproducts from anaerobic degradation of the oil plumes cause increases in total dissolved...

BackgroundDetailed investigations of mercury cycling and bioaccumulation have been done in the Upper Hudson River basin (upstream of the Hudson River near Newcomb, in New York's Adirondack Mountains, with a focus on the Fishing Brook sub-basin, part of the western headwaters of the Hudson River. This study is part of a National mercury study that includes a concurrent study of McTier Creek, a headwater sub-basin of the Edisto River, located in South Carolina's Coastal Plain. These two study areas provide contrasting and complementary settings for the study of mercury cycling and bioaccumulation in headwater streams with close connectivity to out-of-channel wetlands. Atmospheric deposition is the dominant source...
