Determination of COD, BOD, and suspended solids loads during combined sewer overflow (CSO) events in some combined catchments in Spain

Rapid assessment of the cost-effectiveness of low impact development for CSO control

“…Recent studies highlight the extent of potential impacts to receiving bodies, which vary temporally with antecedent weather conditions, and spatially as a function of differences in land use, population density, traffic intensity as well as urban planning and drainage policies between catchments (Butler and Davies, 2004;Suarez and Pertas, 2005). The concentrations of suspended solids and particulate phase organic pollutants in effluent from one of Boston's largest CSOs approach those of untreated sewage, and the influence of the CSO on local water quality is evidenced by similarities between the organic chemical composition of the CSO effluent and those in the receiving waters (Eganhouse and Sherbolm, 2001).…”

First flush of storm runoff pollution from an urban catchment in China

“…Urban runoff pollution problems are more difficult to control than steady-state point discharges because of the intermittent nature of rainfall and runoff, the large variety of pollutant source types, and the variable nature of source loadings. Urban runoff pollution has been studied in developed countries (Gnecco et al, 2005;Suarez and Puertas, 2005). However, little information is available on storm runoff pollution from urban area in developing counties, including China.…”

Diffuse pollution loading from urban stormwater runoff in Daejeon city, Korea

“…Averaged EMC values of the stormwater runoff were 373 mg TSS/L, 395 mg TCODcr/L, 129 mg TBOD/L, 16 mg TN/L, and 13 mg TP/L. These values are lower than those from the literature (Suarez and Puertas, 2005), yet result in significant contaminant loading to the receiving water. The EMC of the BOD was substantially high, considering that the influent BOD concentration to the wastewater treatment plant was only 70 mg BOD/L.…”
