“…Considering the consistent performance of the treatment plant, it can be concluded that overflows are the main contribution to the continuous deterioration of DO and ammonium concentrations in the river, as indicated by DO-M, DO-DU, AMM-M and AMM-DU. This further confirms earlier work (Butler and Davies, 2004;Even et al, 2007).…”

“…Since Harremoës (1982) first reported the delayed impact of CSO discharges on oxygen concentrations, it has been widely recognised that CSO discharge is a significant pollution source and can pose a serious impact on water quality of receiving waters and aquatic environment (Butler and Davies, 2004;Chen et al, 2004;Even et al, 2007). The discharge volume is usually used as an objective to control the sewer system or treatment plant in an integrated urban wastewater system.…”

“…Combined sewer overflow (CSO) water is a mixture of urban runoff and municipal wastewater; is discharged into rivers and canals during heavy rainfall; releases dissolved contaminants, particulate organic matter loads, oxygen consumption, bacteria and viruses, causing fish death and health risks [1] [2]. CSO under wet weather and permanent dry weather impacts the river quality spatially and temporally [1].…”

Combined Sewer Overflows (CSOs) Impact on Water Quality and Environmental Ecosystem in the Harlem River

The Harlem River, a 9.3-mile channel that flows from the Hudson River to the East River, has experienced decades of industrial abuse and remains gritty and industrial. During heavy rains, the pipes discharge raw sewage into the river through combined sewer overflows (CSOs) that can contain bacteria and cause illness. Water samples were collected from CSO discharge point and several adjacent sites along the river in the Bronx side close to River Park Towers at Richman Plaza and Manhattan side at Wards Island. Nutrients, bacteria, polychlorinated biphenyls (PCBs), and fish consumption safety have been analyzed. Results showed that phosphorus, ammonia concentration as well as fecal coliform, E.Coli, enterococcus levels increased significantly during heavy rainstorms. Ammonia concentration was up to 2.725 mg/L during tropical storm Arthur on C 12 H 8 C l2 ), the high molecular weight (MW), an indicator of raw sewer and storm water runoff in the NYC harbor waters, is the major polychlorinated biphenyls (PCBs) in the Harlem River. PCBs are carcinogenic, which could bioaccumulate via food chain from fish and seafood, endangering public health. Oyster farming has been used to purify water and improve water quality in the river. CSOs and storm water runoff have degraded water quality and been threatening environmental ecosystem and public health. This research will help local communities understand CSO impact on nutrients, bacteria, PCBs contamination and fish consumption safety, and make contributions on CSOs reduction as well as improve water quality and environmental ecosystem in the Harlem River.

“…(US EPA, 2004) Some of the impacts of CSO in surface water bodies include decrease of dissolved oxygen concentration due to biodegradation of the increased amount of organic matter, increased levels of metallic and organic pollutants, and high concentration of fecal microorganisms. (Even et al, 2007;Weyrauch et al, 2010;Gasperi et al, 2008) The amount of fecal microorganisms in surface waters is a public health concern because of the possible presence of human pathogens. This is especially a problem for waters that are designated for recreational uses.…”

The purpose of this project was to understand fecal microorganism contamination in the Bronx River within New York City and how it is affected by combined sewer overflow (CSO) events. Nine sites along the Bronx River were sampled throughout the summer of 2014 during wet and dry weather conditions. The samples were analyzed for enterococcus fecal indicator bacteria (FIB) concentration. The data revealed that wet weather enterococci concentrations are as 3 to 28 times greater than dry weather concentrations. The highest enterococci concentrations were found where the river enters Bronx County from Westchester County and near a storm water outfall. The positive correlation shown between the amount of rainfall and the FIB concentrations verifies that CSO and storm water discharges are a major source of FIB contamination in the river.PeerJ PrePrints | http://dx.doi.org/10.7287/peerj.preprints.750v1 | CC-BY 4.0 Open Access |
