“…In our study, most of the water parameters have a significant negative correlation (P < 0.01) with rainfall volume. These results are similar to those found in a previous study by Kim et al (2007) which found that the wide distribution of event mean concentrations (EMCs) is dependent on the total rainfall due to the dilution effect during a storm.…”

a b s t r a c tThere is an urgent requirement to examine the quality of harvested rainwater for potable and nonpotable purposes, based on the type of roofing material. In this study, we examined the effect on the quality of harvested rainwater of conventional roofing materials (concrete, asphalt and ceramic tile roofs) compared with alternative roofing materials (green roof). The results showed that the ceramic tile roof was the most suitable for rainwater-harvesting applications because of the lower concentrations of leachable pollutants. However, in this study, the green roof was not suitable for rainwater harvesting applications. In addition, seasonal trends in water quality parameters showed that pollutants in roof runoff in summer and autumn were lower than those in winter and spring. This study revealed that the quality of harvested rainwater was significantly affected by the roofing material; therefore, local government and urban planners should develop stricter testing programs and produce more weathering resistant roofing materials to allow the harvesting of rainwater for domestic and public uses.

“…The mean EMCs for TN, TKN, NH 3 -N, NO 3 -N, TP and orthophosphate were 1.57, 1.19, 0.32, 0.36, 0.19 (Kim et al, 2007a) for which the nature of the impermeable surface was not identified. Rushton (2002) calculated the maximum nutrient loadings (kg ha -1 .year) released from an asphalt car park surface to be 2.04, 0.57, 0.81, 0.34 and 0.19 for TN, NH 3 -N, NO 3 -N, TP and orthophosphate, respectively.…”

Traffic emissions contribute significantly to the build-up of diffuse pollution loads on urban surfaces with their subsequent mobilisation and direct discharge posing problems for receiving water quality. This review focuses on the impact and mitigation of solids, metals, nutrients and organic pollutants in the runoff deriving from car parks. Variabilities in the discharged pollutant levels and in the potentials for pollutant mitigation complicate an impact assessment of car park runoff. The different available stormwater best management practices and proprietary devices are reported to be capable of reductions of between 20% and almost 100% for both suspended solids and a range of metals. This review contributes to prioritising the treatment options which can achieve the appropriate pollutant reductions whilst conforming to the site requirements of a typical car park. By applying different treatment scenarios to the runoff from a hypothetical car park, it is shown that optimal performance, in terms of ecological benefits for the receiving water, can be achieved using a treatment train incorporating permeable paving and bioretention systems. The review identifies existing research gaps and emphasises the pertinent management practices as well as design issues which are relevant to the mitigation of car park pollution.

“…EMC can be used in water quality management 266 and concentration control for a catchment. EMC is regarded as a good measure to represent 267 rainfall runoff quality (Kim et al, 2007;Lee and Bang, 2000). A close relationship between rainfall amount and runoff depth is shown in Fig.4a.…”

23This paper investigates the frequency distribution of urban runoff quality indicators using a 24 long-term continuous simulation approach and evaluates the impacts of proposed runoff control 25 schemes on runoff quality in an urbanizing catchment in Shenzhen, China. Four different 26 indicators are considered to provide a comprehensive assessment of the potential impacts: total 27 runoff depth, event pollutant load, event mean concentration, and peak concentration during a 28 rainfall event. The results obtained indicate that urban runoff quantity and quality in the catchment 29 have significant variations in rainfall events and a very high rate of non-compliance with surface 30 water quality regulations. Three runoff control schemes with the capacity to intercept an initial 31 runoff depth of 5mm, 10mm, and 15mm are evaluated, respectively, and diminishing marginal 32 benefits are found with increasing interception levels in terms of water quality improvement. The 33 effects of seasonal variation in rainfall events are investigated to provide a better understanding of 34 the performance of the runoff control schemes. The pre-flood season has higher risk of poor water 35 quality than other seasons after runoff control. This study demonstrates that frequency analysis of 36 urban runoff quantity and quality provides a probabilistic evaluation of pollution control measures, 37 and thus helps frame a risk-based decision making for urban runoff quality management in an 38 urbanizing catchment. 39 40
