“…A qualitative approach based on hydrocarbon fingerprints confirmed the significant role of household effluents as wastewater hydrocarbon polluters. Although street cleaning waters are characterized by a larger proportion of unresolved and aromatic compounds (11), their contributions to imported hydrocarbon fluxes are relatively moderate, ranging from 10 to 20% for UCMs and PAHs. On the other hand, the assessment of hydrocarbon fluxes at the "Le Marais" catchment scale pointed out that imported hydrocarbon fluxes are higher than those exported to the urban catchment (Table 3).…”

“…Therefore, the pollutant load conveyed by street cleaning waters for different streets of the "Le Marais" catchment area was investigated by Gasperi et al (11). For the "Le Marais" streets, median AH, UCM and PAH concentrations in street cleaning waters were evaluated to be 19, 628 and 1.4 µg·l −1 , respectively ( Table 2).…”

“…During dry weather periods, strictly domestic effluents (DE 1 ) and domestic effluents mixed with mechanic (DE 2 ) or catering effluents (DE 3 ) were sampled at different locations with automatic samplers (10). Street cleaning waters (SCW) were collected during street cleaning campaigns, performed in collaboration with Paris's Municipality Cleansing Services in four of the "Le Marais" catchment's streets (11). During the wet weather period, roof runoff (RR) was studied for three roofs, with different types of roof covering and gutter materials (14).…”

“…Several investigations have been performed independently in the "Le Marais" catchment since 1994 in order to evaluate the pollutant loads entering the combined sewer via street cleaning waters and domestic effluents (10,11), or via street and roof runoff (12)(13)(14), as well as the pollutant fluxes conveyed by dry and wet weather flows at the catchment outlet (15). At the same time, pollutant stocks associated to in-sewer deposits were studied (16).…”

An experimental catchment area was set up by the CEREVE (Water, City, Environment and Education Research Centre) in the center of Paris, in order to obtain an accurate description of the urban pollutants within combined sewers. Several investigations were carried out between 1994 and 2005 in order to evaluate the aliphatic and polycyclic 123 124 J. Gasperi et al.aromatic hydrocarbon loads entering combined sewers, as well as the pollutant fluxes conveyed by dry and wet weather flows at catchment outlets. Until now, such results have only been considered independently but neither a comparison between imported and exported hydrocarbon loads nor an assessment of the contributions of different sources (e.g., runoff, dry weather flow and deposit re-suspension within the sewer) to wet weather pollutant loads, have been established. This paper is designed to address these points. The assessment of hydrocarbon loads during dry weather periods underlined a predominant contribution of domestic inputs to the hydrocarbon loads. During wet weather periods, the evaluation of hydrocarbon loads revealed the important role played by in-sewer sediment erosion as a source of wet weather hydrocarbon loads, which contribution ranged from 48 to 55% of the exported loads.

The Seine River basin (France) is representative of the large urbanised catchments (78,650 km2) located in Northwestern Europe. As such, it is highly impacted by anthropogenic activities and their associated emissions of pollutants such as polycyclic aromatic hydrocarbons (PAHs). These compounds, originating from household heating and road traffic, are responsible for serious environmental issues across the basin. This study aims at establishing and using mass balance analyses of PAHs at the Seine River basin scale as an efficient tool for understanding PAH pathways in the environment. A dual-scale approach (urban vs. rural areas) was used successfully, and mass balances provided useful knowledge on the environmental fate of PAHs. In urban areas, runoff and domestic and industrial discharges contributed similarly to the PAH supply to the sewer system. During the wastewater treatment process, PAHs were mainly eliminated through sludge removal. At the basin scale, substantial amounts of PAHs were quantified in soils, and the limited annual inputs and outputs through atmospheric deposition and soil erosion, respectively, suggest that these compounds have long residence times within the basin. While wastewater and runoff discharges from urban areas account for a substantial part of PAH urban fluxes to the Seine River, soil erosion seems to be the predominant contributor at the basin scale. Overall, the PAH flux at the basin outlet was greater than supplies, suggesting that the Seine River system may currently be undergoing a decontamination phase.

Street Dust: Implications for Stormwater and Air Quality, and Environmental Management Through Street Sweeping

Street dust represents a source of dual potential risk to stormwater and air quality. It has been well documented that street dust washes into local watersheds and can degrade water quality. Research has also demonstrated that ambient particulate matter (PM10) , which is associated with adverse health outcomes, can arise from resuspension of accumulated street dust. Furthermore, many contaminants, including metals, are present at higher concentrations in the smallest available particles, which are more likely to be resuspended in air and stormwater runoff. Although street cleaning is listed as a best management practice for storm water quality by the EPA, data are limited on the critical parameters (technology, environment, usage), which determine the effectiveness of any street cleaning program, particularly in the peer-reviewed literature. The purpose of the present study was to develop a comprehensive understanding of the efficacy of various street cleaning technologies and practices to protect both water quality and public health. Few studies have compared the effectiveness of street sweeping technologies to remove street dust. Unfortunately, the dearth of comprehensive data on exposure, contaminant concentrations, and efficacy of various sweeping technologies and strategies precludes developing quantitative estimates for potential risk to humans and the environment. Based on the few studies available, regenerative air street sweepers appear to provide the most benefit with regard to collection of small particles and prevention of re-entrainment. It is also clear from the available data that local conditions, climate, and specific needs are critical determinants of the ideal street sweeping strategy (technology, frequency, speed, targeted areas, etc.). Given the critical need for protection of water and air quality in rapidly expanding urban regions (e.g., megacities), further research is necessary to develop best practices for street dust management. Herein, we provide a framework for future experimental studies to support risk-based assessments of street cleaning technologies.
