TSS Sources in Stormwater

Unfortunately, total suspended solids (TSS) in storm water discharges come from everywhere on your industrial site. As we discussed in the last post, there are some pretty powerful regulatory and environmental drivers necessitating a good understanding of where TSS is coming from. In this blog, we look at the potential sources of TSS, which will shape how to best attack the problem and implement some best management practices (BMPs) in our third part of the series.

Sources of TSS can be track-on (hello, nearby construction site) or onsite stockpiles if you are a building materials supply company or aggregate processing plant. Unpaved sites, which means many industrial sites, are the worst for dealing with TSS. Not only are the solids from between the gravel yard getting washed into channels and drains as sheet flow, but the aggregates themselves are getting ground down and fine particulates are being generated. This makes unpaved dirt and gravel yards a perpetual source of TSS issues. However, sites that are paved, but have not maintained landscaped areas can be causing TSS issues from non-industrial areas.

TSS is a common industrial stormwater pollutant and one that challenges facilities because of its’ ubiquitous nature. For the full post, check out Ryan’s guest post on SWS.
