“…Settling of grit, sediment toxins and heavy oils was the primary treatment mechanism. A Continuous Deflective Separation (CDS) unit was used to treat urban runoff in Florida (Rushton 2004 trash and larger sediments. A treatment train approach was implemented at the Miami International Airport to treat stormwater runoff from the facility (Schmidt et al 2004).…”

The composition of the sediment (organic matter and other litter, vs inert material) affects the association of PAHs with the sediment.…”

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.

“…Studies have also documented the impact of sediment texture and organic content affecting PAH associations with sediment [11]. Investigations have found high PAH concentrations associated with large organic material (leaf and other vegetation litter) trapped in stormwater floatable controls [12], further indicating that sediment composition affects the PAHs association with particulate matter, especially those solids high in organic content. Li et al [13] also observed a strong positive relation between sediment total organic carbon or black carbon and its PAH concentrations.…”

Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants of high environmental concern with known carcinogenic activity. Although literature documents PAH fate in urban runoff, little is known about their distribution on sediment sizes, which is essential for determining their treatability and fate in receiving waters. This paper has quantified the concentrations of selected PAHs in urban creek sediments and examined possible relationships between sediment PAH content and sediment characteristics, such as particle size, volatile organic content (VOC), and sediment chemical oxygen demand (SCOD). SCOD, VOC, and PAH concentrations of sediments showed a bimodal distribution by particle size. The large diameter sediments had the highest VOC and also had the highest PAH concentrations. The spatial variation of PAH content by sediment sizes also was statistically significant; however, the mass of the PAH material was significantly affected by the relative abundance of the different particle size classes in the sediment mixtures.
