CHAPTER 3 – Chemistry: Chemistry determines the speciation of the constituents in stormwater such as metals, ammonia, and phosphorus, and in turn, the manner of their sorption to soils and sorptive media. These relationships directly affect the performance of treatment systems.

Some of the questions considered in Chapter 3

• What are the basic processes of chemistry and why does it matter to stormwater treatment?
• What are humic compounds and what is their significance in stormwater treatment?
• What are colloids and what is their significance in stormwater treatment?
