An effective amount of at least one second bacteria may be added to a wastewater stream within a water treatment system. The wastewater stream may have or include an aqueous-based fluid, a first bacteria and organic acids. The second bacteria may be or include, but is not limited to facultative bacteria, spore-forming bacteria, phenol degrading bacteria, denitrifying bacteria, organic acid-degrading bacteria, high temperature bacteria, and combinations thereof. The addition of the second bacteria the wastewater treatment system may at least partially reduce the amount of the organic acids within the wastewater stream as compared to an otherwise identical wastewater stream in the absence of the second bacteria.
