“…Iron levels exceeding Australian guidelines and elevated (but below guideline) levels of Arsenic have also been identified as potential risks for managed aquifer recharge with stormwater, with overall chemical risks from various compounds posited to be low (Page et al, 2010a(Page et al, , 2010b. Heavy metals and pathogens are thought to be the drivers of human health risks for exposure to stormwater (Page et al, 2010a(Page et al, , 2010b(Page et al, , 2010c(Page et al, , 2010dChong et al, 2013;Ma et al, 2016). Indeed, public perception of microbial risks, in particular, remains a crucial barrier to the expansion of water recycling and reuse (Higgins et al, 2002).…”

Editor: Patricia HoldenDemands on global water supplies are increasing in response to the need to provide more food, water, and energy for a rapidly growing population. These water stressors are exacerbated by climate change, as well as the growth and urbanisation of industry and commerce. Consequently, urban water authorities around the globe are exploring alternative water sources to meet ever-increasing demands. These alternative sources are primarily treated sewage, stormwater, and groundwater. Stormwater including roof-harvested rainwater has been considered as an alternative water source for both potable and non-potable uses. One of the most significant issues concerning alternative water reuse is the public health risk associated with chemical and microbial contaminants. Several studies to date have quantified fecal indicators and pathogens in stormwater. Microbial source tracking (MST) approaches have also been used to determine the sources of fecal contamination in stormwater and receiving waters. This review paper summarizes occurrence and concentrations of fecal indicators, pathogens, and MST marker genes in urban stormwater. A section of the review highlights the removal of fecal indicators and pathogens through water sensitive urban design (WSUD) or Best Management Practices (BMPs). We also discuss approaches for assessing and mitigating health risks associated with stormwater, including a summary of existing quantitative microbial risk assessment (QMRA) models for potable and non-potable reuse of stormwater. Finally, the most critical research gaps are identified for formulating risk management strategies.Crown

“…Eq. (1) was modelled via a linear geostatistical model to account for spatial variability in the build-up data (Ma et al, 2016). In order to ensure the linear relationship between dependent and independent variables, logarithmic transformation of build-up load and DTV was carried out.…”

Editor: Adrian CovaciAmong the numerous pollutants present in urban road dust, polycyclic aromatic hydrocarbons (PAHs) are among the most toxic chemical pollutants and can pose cancer risk to humans. The primary aim of the study was to develop a quantitative model to assess the cancer risk from PAHs in urban road dust based on traffic and land use factors and thereby to characterise the risk posed by PAHs in fine (b150 μm) and coarse (N 150 μm) particles. The risk posed by PAHs was quantified as incremental lifetime cancer risk (ILCR), which was modelled as a function of traffic volume and percentages of different urban land uses. The study outcomes highlighted the fact that cancer risk from PAHs in urban road dust is primarily influenced by PAHs associated with fine solids. Heavy PAHs with 5 to 6 benzene rings, especially dibenzo [a,h]

“…Three studies in 2016 focused on the potential human and ecological risk of heavy metal and PAHpolluted stormwater runoff from roadways Ma et al, 2016). To investigate the potential of reuse of stormwater runoff from roadways, Ma et al (2016) the researchers also determined that health risk is significantly influenced by traffic volume and industrial land-use mirroring correlations found between heavy metals in roadway runoff and traffic volume and land-use. also saw a correlation between PAHs with 4+ rings (PAHs which pose the greatest health risk) and traffic congestion.…”

A summary of 246 studies published in 2016 on topics related to the characterization and management of urban stormwater runoff is presented in the following review. The review is structured along three major topical areas: (1) general characterization of stormwater quantity and quality; (2) engineered systems for stormwater control and treatment, including erosion and sediment control practices, constructed stormwater ponds and wetlands, bioretention, permeable pavement, greenroofs, and rainwater harvesting and (3) watershedscale application of stormwater treatment and control practices. Common research themes and needs highlighted throughout this review include efforts to better understand stormwater transport and treatment mechanisms and their representation in models, advancements to optimize the design of stormwater control measures to meet specific hydrologic and/or water quality targets, and increasing understanding of the biophysical and social factors that influence watershed-scale implementation of low impact development and other stormwater control measures.
