“…Much better evaluations of the controllability of the pollutants, and selection of controls, is possible with this information. Clark and Pitt (2012) describe how different stormwater treatment technologies relate to the stormwater characteristics affecting treatability.…”

This paper summarizes the results of several stormwater research projects that investigated particulate pollutant strengths for different particle size ranges. This paper builds on the previous paper simultaneously published describing particle size distributions of stormwater particulates (Pitt et al. 2016). The pollutant strength information presented in this paper, along with the particle size distribution in the other paper, is critical when understanding the routing of stormwater particulates through urban systems and especially when calculating the expected performance of stormwater controls. The pollutant concentrations commonly have a bimodal distribution, with higher values for small particles (due to large surface areas) and sometimes for large particles (such as for polycyclic aromatic hydrocarbons, PAHs, that are strongly associated with large organic debris). In most cases, the majority of the stormwater pollutant masses at outfalls are associated with small and moderate-sized particulates (usually from ~10 µm to 200 µm) which are effectively transported through drainage systems. Stormwater controls that focus on larger particles (such as >300 µm) that are more abundant at source areas may have less effective benefits on discharged stormwater quality as they only contribute small fractions of the total particulate mass after being poorly transported through most drainage systems. Treatability tests show that effective removal of particulate-bound stormwater pollutants requires the control of the small particles, usually down to ~10 µm in size. Pre-treatment stormwater controls that focus on larger particles reduce maintenance issues and provide other benefits, but need to be supplemented with additional controls that are effective in the removal of small particles, usually in a treatment train arrangement.

“…An abundant number of papers have highlighted the existence of pollution from diffuse sources over the last 40 years (Clark and Pitt, 2012). When most effluent discharges were moderately controlled, stormwater then became one of the largest non-point pollution sources contributing to the degradation of surface water resources (National Research Council, 2008).…”

“…As discussed by Clark and Pitt (2012), while infiltration practices are often designed according to empirical recommendations, and their treatment performance extrapolated from a limited number of field studies, a better understanding of the retention mechanisms taking place could valuably improve their choice, design and maintenance. Additionally, soil clogging by runoff sediment has often been reported as a major concern in infiltration systems, but it remains difficult to characterize and quantify the state of clogging in a given device, or even to anticipate the occurrence of hydraulic malfunction (Cannavo et al, 2018).…”
