“…Due to the high variability in pollutant concentrations throughout a given stormwater runoff event, the EMC was used as a measure to compare the pollution between rain events (Sansalone and Buchberger 1997;Lee and Bang 2000).…”

“…For PC3, it accounted for 12.73 % of the total variance and had strong and positive loadings on DPb and a moderately positive loading on DZn. The Zn and Pb pollution was mainly sourced from vehicle exhaust (Sansalone and Buchberger 1997;Huang et al 2007), but Mangani et al (2005) reported tire wear as a significant source for Zn and Davis et al (2001) and Ball et al (1998) reported that Pb is sourced from lubrication oil and grease. Thus, PC3 mainly results from vehicle emission.…”

“…The source partition is also a very important issue for pollution control; Sansalone and Buchberger (1997) found that zinc (Zn) and lead (Pb) were mainly sourced from vehicle exhaust; Davis et al (2001) found that the most likely source of copper (Cu) was the wear of brake linings and moving engine parts; Huang et al (2007) found that organic matter in road runoff mainly came from vehicle activities; and Drapper et al (2000) found that total organic carbon (TOC) and COD concentration on asphaltum roads were three to five times higher than on concrete roads. Recently, a multivariate technique has been developed for partitioning the source of water pollution.…”

This study investigates the quality of stormwater runoff from a driveway in the southwest mountainous urban area of Chongqing, China, from 2010 to 2011. The results showed that the mean concentrations of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) were 4.1, 2.4, and 2.2 times the grade V levels of the national surface water standard of China. The pollutant concentration peak preceded or synchronized with the rainfall intensity peak and occurred 10 min after the runoff started. The significant high pollutant concentration in the initial stage of the rainfall suggested that first flush control is necessary, especially for the most polluted constitutes, such as total suspended solids, COD, and TN. Three potential pollution sources were identified: the atmospheric dry and wet deposition (TN, NO 3 − -N, NH 4 + -N, and DCu), the road sediment and materials (total suspended solids, COD, and TP), and the vehicle emissions (DPb and DZn). Therefore, this study indicates that reductions in road sediments and material pollution and dry and wet deposition should be the priority factors for pollution control of road stormwater runoff in mountainous urban areas.

Abstract:The dense highland field area in the upstream region of the Lake Soyang watershed is subject to excessive soil erosion during the wet season. In this study, stormwater runoff from the Lake Soyang watershed was monitored during four rainfall events at 10 locations throughout 2016. The maximum SS concentration at Naedongcheon, which is located in the upper part of the Soyang River, reached 4598 mg/L. The event mean concentration (EMC) of SS loads in Naedongcheon ranged from 82.2 mg/L to 926.3 mg/L. We found that, although the first flush events were usually concentrated in highly paved urban areas, a first flush occurred in the agricultural area of the dense highland field region. The first flush phenomenon was identified by a dimensionless cumulative runoff mass and volume curve (M(V) curve), and the intensity of the first flush was analyzed by the coefficient of the nonlinear regression model and the FF 30 and FF 25 values (the fraction of pollution load transported by the first 30% and 25% of runoff, respectively). Nonlinear regression models using the power function were applied to fit the M(V) curve, the FF 30 values were inversely proportional to the coefficient a of the regression model. A long-term seasonal trend decomposition for monthly turbidity and precipitation was performed for the Lake Soyang. Long-term turbidity trend was approximately coincident with the trend in long-term precipitation. In addition, the present status of the best management practices (BMPs) in the upper part of the Soyang River basin was investigated, and a survey of the management and operation of the BMPs was conducted for selected farmers.

“…As pollutant concentrations can vary by orders of magnitude during a runoff event, the flow weighted average or event mean concentration samples (EMC) were found to be appropriate for evaluating the impacts of stormwater runoff on receiving waters (18). In this study, 500 mL EMC samples in amber glass bottles were prepared in the laboratory using a churn splitter.…”

Traffic generated semi and non volatile organic compounds (SVOCs and NVOCs) pose a serious threat to human and ecosystem health when washed off into receiving water bodies by stormwater. Climate change influenced rainfall characteristics makes the estimation of these pollutants in stormwater quite complex. The research study discussed in the paper developed a prediction framework for such pollutants under the dynamic influence of climate change on rainfall characteristics. It was established through principal component analysis (PCA) that the intensity and durations of low to moderate rain events induced by climate change mainly affect the wash-off of SVOCs and NVOCs from urban roads. The study outcomes were able to overcome the limitations of stringent laboratory preparation of calibration matrices by extracting uncorrelated underlying factors in the data matrices through systematic application of PCA and factor analysis (FA). Based on the initial findings from PCA and FA, the framework incorporated orthogonal rotatable central composite experimental design to set up calibration matrices and partial least square regression to identify significant variables in predicting the target SVOCs and NVOCs in four particulate fractions ranging from >300-1 μm and one dissolved fraction of <1 μm. For the particulate fractions range >300-1 μm, similar distributions of predicted and observed concentrations of the target compounds from minimum to 75th percentile were achieved. The inter-event coefficient of variations for particulate fractions of >300-1 μm were 5% to 25%. The limited solubility of the target compounds in stormwater restricted the predictive capacity of the proposed method for the dissolved fraction of <1 μm.
