“…Azole antifungals have been detected in wastewater and surface water in Europe (Berenzen et al, 2005;Gasperi et al, 2008;Kahle et al, 2008;Lindberg et al, 2010;Peschka et al, 2007;Roberts and Thomas, 2006;Stamatis et al, 2010;Thomas and Hilton, 2004;Van De Steene and Lambert, 2008). Persistence of clotrimazole, fluconazole, tebuconazole, and propiconazole has also been reported (Kahle et al, 2008;Lindberg et al, 2010).…”

“…The resulting concentrations of wastewater constituents in the Bauerngraben during CSOs may be lower than in the wastewater due to dilution from precipitation and mixing with water from the Bauerngraben, but can still be higher than in the groundwater. Gasperi et al (2008) compared wastewater concentrations during wet-weather and dry-weather conditions and found out that concentrations during wet-weather conditions are not strictly reduced. The erosion of in-sewer deposits formed within sewer during dry periods was identified as a potential reason for this.…”

Abstract. Losing streams that are influenced by wastewater treatment plant effluents and combined sewer overflows (CSOs) can be a source of groundwater contamination. Released micropollutants such as pharmaceuticals, endocrine disrupters and other ecotoxicologically relevant substances as well as inorganic wastewater constituents can reach the groundwater, where they may deteriorate groundwater quality. This paper presents a method to quantify exfiltration mass flow rates per stream length unit M ex of wastewater constituents from losing streams by the operation of integral pumping tests (IPTs) up-and downstream of a target section. Due to the large sampled water volume during IPTs the results are more reliable than those from conventional point sampling. We applied the method at a test site in Leipzig (Germany). Wastewater constituents K + and NO stream d −1 ) revealed the highest observed M ex values at the test site. The micropollutants caffeine and technical-nonylphenol were dominated by elimination processes in the groundwater between upstream and downstream wells. Additional concentration measurements in the stream and a connected sewer at the test site were performed to identify relevant processes that influence the concentrations at the IPT wells.

“…(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 |
