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...

Low-Flow Characteristics

Streamflow data collection and analysis are a necessary component of effective water resource management and planning.  Low-flow statistics are needed to safely allow withdraws from and discharges to surface waters in the State of New Jersey.  Operating streamflow gaging stations at every water use location would be ideal but is cost prohibitive. Statistics help extend the utility of available...

The complex spatial distribution of trichloroethene and the probability of NAPL occurrence in the rock matrix of a mudstone aquifer

Methanol extractions for chloroethene analyses are conducted on rock samples from seven closely spaced coreholes in a mudstone aquifer that was subject to releases of the nonaqueous phase liquid (NAPL) form of trichloroethene (TCE) between the 1950's and 1990's. Although TCE concentration in the...

Revisiting the avian Eco-SSL for lead: Recommendations for revision

The avian ecological soil screening level (Eco-SSL) for lead (11 mg/kg) is within soil background concentrations for >90% of the US. Consequently, its utility as a soil screening level is limited. Site-specific ecological risk-based remedial goals for lead are frequently many times greater. Toxicity reference values (TRVs) play a major role in...

Future directions to escalate benefits of stepping-stone approach for conservation translocations

Through a reintroduction case study on the critically endangered Vancouver Island marmot (Marmota vancouverensis), we introduced a ‘stepping-stone’ approach which utilizes the transition of released individuals among populations to maximize demographic growth potential (Lloyd et al. 2019). We greatly appreciate and hereby reflect on the...

Coelomic disorders of fishes

Dropsy is a commonly applied term for coelomic distention due to ascites, or the effusion and collection of fluid freely throughout the coelomic cavity. Dropsy, or ascites, is generally a sign of another ongoing disease process, oftentimes one that is multisystemic and impacting coelomic organs and tissues. Dropsy may be caused by a variety of...

Perfluoroalkyl contaminant exposure in tree swallows nesting at Clarks Marsh, Oscoda, Michigan, USA

A site in north eastern Michigan, Oscoda Township, has some of the highest recorded exposure in birds to perfluorinated substances (PFASs) in the U.S. Some egg and plasma concentrations at that location exceeded the lowest reproductive effect threshold established for two avian laboratory species. The objectives of this study were to determine...

Detecting the undetectable: Characterization, optimization, and validation of an eDNA detection assay for the federally endangered dwarf wedgemussel, Alasmidonta heterodon (Bivalvia: Unionoida)

Environmental (e)DNA assays are valuable tools for monitoring presence and distribution of cryptic species. Like many freshwater mussels, the dwarf wedgemussel, Alasmidonta heterodon numbers have dwindled and its range has diminished. As of its listing in 1993, only 10 to 20 locations were known to persist of the 70 Atlantic slope locations known...

Pathways to strategic communication for biodiversity conservation: Response to “Hearing ourselves (and acting in consequence): A commentary on Bekessy et al. from a bird-handling environmental education perspective”

Central to discussions about the merits of ecosystem services as a communication strategy is the degree to which it represents a strategic and effective approach to advance biodiversity conservation. There is increasing recognition that many conservation communication efforts can be more strategic (e.g. Kusmanoff et al. 2016).
