November 2017 – Rutgers2030_PublicAccessStudio-Report
The Rutgers University 2030 Master Plan is looking for ways to
re-establish the Rutgers-New Brunswick connection between the city and its river. This return to the Raritan is not without obstacles, as there are various regulatory, funding, and stakeholder concerns to consider. This report, produced by a team of graduate students at the Edward J. Bloustein School of Planning and Public Policy, is an examination of two elements in the Rutgers University 2030 Master Plan: a multi-modal bridge spanning the Raritan River and a boardwalk along the river’s edge. Each element presents its own set of challenges and opportunities, which are outlined in the report from three perspectives: 1) access 2) environment and 3) health and safety.
May 2017 – Baykeeper Pathogens Report Public Release (Perth Amboy / South Amboy)
Throughout the course of June 13, 2016 – October 3, 2016, the LRWP, Baykeeper, citizen scientists and other project partners conducted weekly monitoring events at nine locations along the NJ portion of the Raritan Bayshore (Monmouth/Middlesex Counties) – including two sites in Perth Amboy and one site in South Amboy. This project engaged over 25 volunteers, who participated in all aspects of monitoring-GPS and YSI operations, data collection, water sample collection, and laboratory testing. At each site measurements were taken (i.e., temperature, salinity, oxygen, pH) along with observations regarding weather patterns, potential pollution inputs (point and non-point sources), and recreational use (e.g., fishing, boating, swimming). Additionally, water samples were collected, and analyzed at the IEC laboratory, to determine the levels of Enterococcus bacteria (an indicator of pathogen contamination). Data were analyzed to determine the highest areas of Enterococcus, especially immediately following precipitation events. This report presents findings from the Summer 2016 pathogens study.

The first is a Tices Park Inventory and Analysis, and the second a General Management Plan. Daryl’s management plan proposal includes integrating the curriculum of two local schools with the natural resources at the park and using the stream degradation of the Sawmill Brook from up-slope development as an example of the problems faced in the Lower Raritan Watershed.
May 2017 – Designing a Healthier Somerset
Under the guidance of Professor David Tulloch, the Rutgers GeoDesign class took a semester long look at the health of Somerset County, NJ, and identified a number of design interventions that could improve the well-being of the county’s residents. Not surprisingly, so many of their design suggestions would positively impact watershed health.
In 2016 the LRWP commissioned Brian Kempf to develop a white paper to examine the feasibility and opportunities of implementing stormwater utilities at a regional scale. Our evaluation focused on implementation at the County scale.
February 2017 – Bridges of the Lower Raritan Watershed
Working with Professor JeanMarie Hartman, Rutgers Undergraduate Ethan Benderly-Kremen developed this inventory of iconic bridges in the Lower Raritan Watershed. The inventory includes information on bridge construction, age and purpose. Ethan writes: “the bridges of the Lower Raritan are a misunderstood feature, used by almost all but noticed by almost none. By showing how the bridges are different from an ordinary road, and how each bridge is different from another, I hope to demonstrate to the reader that by crossing a bridge, they are directly interacting with a major river, a feature unique to this area, hopefully spurring them to continue learning and interacting with the Raritan.”
January 2017 – Cornell Dubilier superfund site 5 year report (South Plainfield)
The Cornell-Dubilier Electronics, Inc. (CDE) Superfund site located in South Plainfield, New Jersey. The former CDE facility, encompassing 26 acres in size, was previously used by a variety of commercial and industrial tenants. CDE operated at the facility from 1936 to 1962, manufacturing electronic components, including capacitors containing polychlorinated biphenyls (PCBs) and chlorinated organic solvents. The company disposed of PCB-contaminated materials and other hazardous substances directly on the property soils. CDE’s activities led to widespread contamination of soil, sediment and groundwater with PCBs, metals and volatile organic compounds (VOCs). The site’s long-term cleanup, overseen by the Environmental Protection Agency, is ongoing. This document is the second five year review report for clean-up activities.
January 2017 – Raritan River Robert Street Dam Removal
John Jengo is a Hydrogeologist & Dam Removal Project Manager for many of the dam removals on New Jersey’s Raritan River. He developed this paper summarizing the successful removal of The Robert Street Dam to restore migratory (anadromous) fish passage. To remove the dam, numerous technical and permitting challenges had to be resolved, including inadequate bridge load capacity that precluded heavy equipment access to the site. Technical obstacles that were overcome during the dam removal included managing the work around frequent upriver reservoir releases, the laborious extraction of over 300 individual sheet piles using two different hydraulic vibratory driver/extractors, and conveyance of over 700 tons of concrete and 70 tons of steel offsite over the five-week removal period.
November 2016 – Historical sources of polychlorinated biphenyls to the sediment of the New York/New Jersey Harbor (journal article)
Rutgers University Department of Environmental Science Professor Lisa Rodenburg and colleagues analyzed dated sediment cores to investigate the pollutant polychlorinated biphenyl (PCB) congener concentrations in the New York/New Jersey Harbor and Lower Hudson River.
August 2016 – Influence of wastewater treatment plant discharges on microplastic concentrations in surface water (journal article)
Rutgers Civil and Environmental Engineering Professors Shirin Estahbanati and Nicole Fahrenfeld studied the abundance of microplastic particles in the freshwater environment of the Raritan River, focusing on samples captured near wastewater treatment plant (WWTP) discharges. To investigate concentration of microplastic in fresh water and the impact of WWTP effluent, samples were collected upstream and downstream of four major municipal WWTPs on the Raritan River, NJ. Microplastics were categorized into three quantitative categories (500-2000 μm, 250-500 μm, 125-250 μm), and one semi-quantitative category (63-125 μm). Then, microplastics were classified as primary (manufactured in small size) or secondary (derived from larger plastics) based on morphology. The concentration of microplastics in the 125-250 and 250-500 μm size categories significantly increased downstream of WWTP. The smaller size classes, often not quantified in microplastic studies, were in high relative abundance across sampling sites. While primary microplastics significantly increased downstream of WWTP, secondary microplastic was the dominant type in the quantitative size categories (66-88%). A moderate correlation between microplastic and distance downstream was observed. These results have implications for understanding the fate and transport of microplastics in the freshwater environment.
May 2016 – Concentrations of heavy metals in fish species targeted by anglers in central New Jersey: A pilot study (journal article)
Rutgers graduate student John Cambridge and co-authors investigated the concentrations of toxic metals in the edible portion of fish tissue obtained from the Raritan River in New Brunswick, New Jersey (NJ) between April and May of 2014. Species collected for this study included commonly caught fish such as bluegill, small and large mouth bass, brown and rainbow trout, bullhead catfish, and white perch. Samples were filleted and the muscle tissue subsequently dehydrated and then chemically digested. Samples were analyzed using Gas chromatography mass spectrometry (GC–MS). Levels of 28 different metals were quantified for each specimen. In general, metal contamination in fish tissues was below the recommended limits. However, lead was found in one sample at a tissue concentration of 88 µg per 225 g fillet, which is above the recommended daily consumption limit as set by the Food and Safety Authority of Ireland. The maximum level found for arsenic was 23 µg per 225 g fillet. The fish samples taken from the Raritan River in New Brunswick, NJ for this study did not contain dangerous levels of most of the metals tested.

June 2015 – Sustainable Cities Design Academy (SCDA 14) Final Report – New Brunswick “Rail Arts River”
December 2014 – The Future of the Lower Raritan Watershed
In Fall 2014 the Lower Raritan Watershed Partnership worked with the Rutgers Landscape Architecture Graduate GeoDesign Studio to study current conditions in the Lower Raritan Watershed and evaluate different alternative futures and associated strategies. The Rutgers GeoDesign Studio began the semester with a challenge: how to understand and describe the Lower Raritan Watershed in content, space and time. Building on a mid-term charrette in which students presented a comprehensive inventory and analysis of the study area, work then expanded towards a larger, more traditional GIS-based regional mapping project to challenge the region’s stakeholders in their thinking about the future of the river and the watershed.
