An Evaluation of SPATT Technology to Assess Cyanotoxins Variability and Transport in the Salem River, New Jersey

As part of the USGS Next Generation Water Observing System the NJWSC is evaluating the use of passive samplers, or Solid Phase Adsorption Toxin Tracking (SPATT) samplers, to examine the temporal variability of dissolved cyanotoxin occurrence. These innovative, low-cost, time-integrated passive samplers offer several advantages over current water-column cyanotoxin monitoring techniques. However...

Downstream Fate and Transport of Cyanobacteria and Cyanotoxins in the Raritan Basin Water Supply Complex, New Jersey

Harmful algal blooms with cyanotoxin production (CyanoHABs) have been shown to adversely affect water resources worldwide, however only a handful of studies have examined the occurrence and persistence of CyanoHABs in fluvial systems used for municipal water-supply. Of particular concern in New Jersey is the Raritan Basin Water Supply Complex (RBWSC) as it is the water supply for multiple water...

Novel Bacterial Monitoring in Urbanized Areas of the Delaware River Basin in Support of Recreational Water Quality Criteria

As part of the Urban Water Federal Partnership, the USGS NJWSC and the Delaware River Basin Commission are currently assessing the use of innovative, near real-time bacteria monitoring technology to provide rapid results on bacteria concentrations to water regulators. Traditional methods of collecting and quantifying fecal indicator bacteria (FIB) is labor intensive, expensive, and may be...

Baseline Water-Quality Inventory for Paterson Great Falls National Historic Park, New Jersey

The Paterson Great Falls National Historical Park (PAGR) in the historic city of Paterson, New Jersey was established in 2011 and consists of natural, cultural, and historic resources associated with the Great Falls of the Passaic River. Due to the park’s young age and limited resources, the park does not have the natural resource data needed to guide future park management and planning decisions...

National Water-Quality Assessment (NAWQA) Program Studies in New Jersey

The USGS National Water-Quality Assessment Project (NAWQA) is now part of the USGS National Water-Quality Program (NWQP). NAWQA provides nationally consistent data and information on the quality of the Nation’s water. Studies provide information on current water-quality conditions, a baseline for trend evaluation, and an understanding of what factors affect water quality. Groundwater studies for...

Monitoring Mercury in Wet Deposition

Mercury accumulates in biological tissue through complex reactions (bioaccumulation). Bacteria convert environmental inorganic mercury into methyl mercury (Me-Hg). This Me-Hg form is more toxic and more difficult to remove from bacterial systems than inorganic mercury. As humans consume fish, the Me-Hg in the fish is also consumed. Neurotoxicity is the most important health concern with mercury...

Stormwater Runoff TMDL for Aquatic Life

Biological impairment is but an indicator that some type of anthropogenic process has occurred resulting in aquatic assemblage degradation. The purpose of this proposal is to establish an applicable TMDL approach to address aquatic life impairments associated with stormwater runoff and hydrologic alteration for streams in New Jersey with the goal of improving river systems by reducing the impact...

Watershed Indicators

Various questions arise on whether or not realistic stream restoration goals can be established with our current understanding of watershed indicators and major controlling factors of aquatic ecosystem health. State-of-the-art statistical, GIS, and hydrologic modeling approaches at multiple levels of data stratification will be extensively used to evaluate the AMNET assessment methodology...
