Pollutants are categorized according to (1) conventional or naturally occurring, (2) unconventional, (3) toxic, (4) heat, and (5) dredge spoils. An example of a conventional pollutant would be biological oxygen demand (BOD). Unconventional pollutants are those that can’t be categorized as naturally occurring or toxic; chemical oxygen, for example. A special class of pollutants similar to dredge spoils is drilling mud.

Although runoff water quality modelling in urban areas has been performed since the 1970s (Sartor and Boyd 1972; Driscol 1979), it remains a challenging and evolving task. Recent studies demonstrate that researchers are continuously improving the modelling practice of urban runoff water quality (Shagun, Lloyd, and Kansal 2021; Zhang et al. 2019; Morgan et al. 2020; Jeung et al. 2019; Rodríguez et al. 2010), but further efforts are required to better understand the role of non-conventional pollutant sources such as cross-connections, failing septic tanks, and illegal discharges (Zhang et al. 2019).
