“…Depressed levels of dissolved oxygen have been a chronic problem in Newark Bay and its tributaries since the early 1900s. 20 Although the dissolved oxygen level is known to be the lowest in the summer season with high water temperature, dissolved oxygen concentrations in the water samples collected in June and July, 2015, along the lower Passaic and Hackensack Rivers, as well as the Newark Bay, were relatively high, ranging from 4 to 10 mg/L. This is consistent with improved water quality in the Hudson Raritan Estuary (HRE) since the enactment of the 1972 Clean Water Act.…”

“…High nutrient inputs from CSOs (combined sewer overflows) or sewage treatment plants may lead to excessive algal and bacterial growth, which may cause hypoxic (low-oxygen) or anoxic (no oxygen) conditions, adversely affecting biological communities.

Water Quality Monitoring of an Urban Estuary and a Coastal Aquifer Using Field Kits and Meters: A Community-Based Environmental Research Project

Water quality is an important interdisciplinary environmental topic for project-based learning. An undergraduate summer research internship program at a public minority serving institution engaged environmental science majors in community-based research experiences. The research focused on the field monitoring of water quality for surface water and groundwater in urban areas of New York and New Jersey that have been heavily impacted by industrialization and urbanization. Groups of students collected water samples from the tidal section of the Passaic River and the Hackensack River, as well as the Newark Bay in New Jersey. Groundwater samples were also collected from a sandy coastal aquifer located in the East Shore of Staten Island, New York. Students analyzed water samples using a portable pH-EC meter, a portable colorimeter, or field test kits for various water quality parameters in the field or laboratory. Students prepared and presented research posters in conferences and at a local community event. The water quality monitoring project helped students to develop field and laboratory research skills, quantitative skills, collaboration skills, as well as written and oral communication skills. The research experiences enhanced students’ attitudes toward science careers and motivated students to pursue degrees in science. The community-based environmental project can be implemented in various undergraduate science courses focusing on the chemistry of natural waters to facilitate inquiry-driven learning and connect classroom learning to the real world.

“…Several point and nonpoint sources of these compounds are present in Newark Bay (USEPA, 1987;NJDEP, 1989). During the course of industrialization over the past century, scrap metal refineries, pulp and paper mills, copper smelters, and a wide range and large number of chemical manufacturing plants, as well as municipal sewage treatment plants and industrial and municipal incinerators, operated near or along the Passaic River and Newark Bay (Meyerson et aI., 1981;McCormick et al, 1983;USEPA, 1987).…”

“…Newark Bay and the lower Passaic River have been adversely impacted by more than a century of industrial and domestic pollution (Mehta et al, 1975;Meyerson et aI., 1981;Mueller et al, 1982;McCormick et al, 1983). Several potential historical and ongoing sources of PCDD/Fs are likely to have contributed to the presence of these compounds in bottom sediments.…”

“…It appears that the lowest DO levels were associated with sewage treatment plants that are located near HR-4 and HR-5 ( Figure 1), including Bergen County Utilities Authority (approximate discharge rate: 69 mgd, million gallons per day), North Bergen Municipal Utilities Authority (approximate discharge rate: 7 mgd), and Secaucus Municipal Utilities Authority (approximate discharge rate: 3 mgd) [32]. Depressed levels of dissolved oxygen, which reduce species abundance and diversity, have been known to be a chronic problem in Newark Bay and its tributaries since the early 1900s [7,33]. While it has been reported that oxygen concentrations in the Hackensack River regularly fall below the New Jersey Department of Environmental Protection's water quality criterion (4.0 mg/L) and U.S. Environmental Protection Agency's protective minimum oxygen concentration (2.3 mg/L) for adult fishes [11], DO of water samples collected from the Newark Bay Estuary in summer 2015 and 2016 ranged approximately from 3 mg/L to 9 mg/L, which is above hypoxia ( Table 1).…”

Abstract:The Newark Bay Estuary in northern New Jersey contains one of the largest urban wetland complexes in the United States, but the majority of the wetlands and habitats have been lost due to urbanization and industrialization. Field and laboratory research was conducted to understand the impacts of human activities on the biogeochemistry of nutrients and heavy metals in the urban estuary. Concentrations of dissolved nutrients such as nitrate, ammonia, and phosphate were higher in the Hackensack River than in the Passaic River or the Newark Bay, while the Hackensack River was more deficient in dissolved oxygen. Sediment oxygen demand and mobilization of nutrients were higher in sediments with higher organic matter content as a result of microbial decomposition of organic matter. Heavy metals (Cr, Cu, Pb, and Zn) and organic matter were more enriched in finer sediment grains such as silt and clay. There were positive correlations among heavy metals as well as organic matter in sediments. The results suggest that fine grained sediments, which can be readily suspended and transported during tidal cycles, may play a significant role in biogeochemical cycling of nutrients and heavy metals in the urban estuary. It appears that the current sources of nutrients and heavy metals in the water and sediment of the Newark Bay Estuary are mainly domestic effluents from sewage treatment plants during non-storm periods as well as combined sewer overflows during storm events, but further research including more frequent and pervasive water and sediment quality monitoring during dry and wet periods is needed.
