Monitoring Water-Quality Response of Conservation Practices in the Bucks Branch Watershed, Sussex County, Delaware

The Bucks Branch sub watershed in the Nanticoke River basin has been identified as having one of the highest concentrations of nitrate in surface water of all sites sampled in Delaware. 

Changes in water quality related to changes in agricultural conservation practices will be seen first in shallow groundwater as groundwater is the major source of nitrate in surface water.

Hurricanes and Storm-Tide Monitoring

The USGS works in partnership with other federal and state agencies to provide scientific data about coastal flood hazards. The New Jersey Water Science Center (NJWSC) maintains a network of continuously operating tide gages along the back bays of New Jersey which provide publicly available water-level and meteorological data to monitor coastal flood conditions.  The USGS NJWSC...

Earthquake Resources

Earthquakes felt in New Jersey are generally few and small. However, some earthquakes have produced damage in New Jersey. New Jersey’s seismic hazard is lower than many earthquake-prone parts of the United States.  Across the state, seismic hazards are highest in northeastern New Jersey.

Hydrogeology and Groundwater Quality of the Anacostia River Watershed

The Anacostia River has been subjected to dredging, filling, contamination, and other human influences for over 200 years. The result of these activities is that the river has been seriously degraded from its natural state. Many groups have been working to reduce the effects of environmental degradation on the water quality and living resources of the Anacostia River, primarily by focusing on...

Detailed Aquifer Mapping of the Oneonta Area Otsego and Delaware Counties, New York

Introduction The City of Oneonta and surrounding area is the major population center in Otsego County, N.Y. and home to two colleges (SUNY Oneonta and Hartwick College). The public water supply draws on both surface-water and groundwater sources and serves 15,954 people in the City of Oneonta and parts of the surrounding Town of Oneonta (City of Oneonta, 2013). The remaining population uses...

Mohawk River Basin Water Quality

Elevated levels of nutrients (for example, phosphorus) in the Mohawk River can lead to eutrophication and potentially toxic blue-green algal blooms. The U.S. Geological Survey (USGS), in cooperation with the New York Department of Environmental Conservation (NYSDEC) collected nutrient samples and measured streamflow in the Mohawk River. These data are being used to develop a water-quality...

Linking environmental and public health data to evaluate health effects of arsenic exposure from domestic and public supply wells

Everyone needs clean drinking water in order to thrive. The US EPA and public water purveyors in the US work together in adherence with the Safe Drinking Water Act to make water safe for public consumption. The recent media coverage of lead in public drinking water supplies in Flint, Michigan, and schools in many cities with aging infrastructure throughout the US has raised public awareness of...

Flood Resources

The USGS reports document New Jersey floods from 1896 to the present. Early spring and winter flooding in New Jersey tends to occur as a result of widespread, steady rain of moderate intensity that falls on frozen ground. Snow and ice melt may increase the chance of winter flooding. Summer flooding resulting from thunderstorms typically occurs in small streams and is of local extent. Late...

Estimation of base flow on ungaged, periodically measured streams in small watersheds in western Pennsylvania

A 2.5-year data collection program was undertaken by the U.S. Geological Survey, in cooperation with the Pennsylvania Department of Environmental Protection (PADEP), to quantify and estimate base flow in small watersheds in western Pennsylvania where only periodic streamflow measurements had been obtained. Twelve streamgages with watershed areas...

Factors affecting species richness and distribution spatially and temporally within a protected area using multi-season occupancy models

Exploring trends in species richness and the distribution of individual species over time as well as the factors affecting these trends informs conservation priorities in protecting species and ecosystems as a whole.

Associations between environmental pollutants and larval amphibians in wetlands contaminated by energy-related brines are potentially mediated by feeding traits

Energy production in the Williston Basin, located in the Prairie Pothole Region of central North America, has increased rapidly over the last several decades. Advances in recycling and disposal practices of saline wastewaters (brines) co-produced during energy production have reduced ecological risks, but spills still...

Dynamic N-mixture models with temporal variability in detection probability

In theory parameters of dynamic N-mixture models can be estimated with multiple years of data without the robust design under the assumption of constant detection probability. However, such an assumption can rarely be met in long-term studies, and the consequences of violating this assumption in the inferences of dynamic N-mixture models have not...

Impact of prey occupancy and other ecological and anthropogenic factors on Tiger distribution in Thailand’s Western Forest Complex

Despite conservation efforts, large mammals such as tigers (Panthera tigris) and their main prey, gaur (Bos gaurus), banteng (Bos javanicus), and sambar (Rusa unicolor), are highly threatened and declining across their entire range. The only large viable source population of tigers in mainland Southeast Asia occurs in Thailand's Western Forest...
