Using super chlorination in reservoirs and storage tanks can temporarily increase what?

The correct response highlights the fact that super chlorination can temporarily increase levels of trihalomethanes (THMs) in water systems. Super chlorination involves adding a higher concentration of chlorine to the water than what is typically used for regular disinfection. This process serves to effectively eliminate a greater number of pathogens and organic matter in reservoirs and storage tanks.

During the super chlorination process, chlorine reacts with organic substances naturally present in the water, leading to the formation of trihalomethanes. These compounds are a byproduct of chlorination, particularly when chlorine interacts with organic material.

Understanding this relationship is crucial for water operators, as the formation of trihaolmethanes needs to be monitored because they can have health impacts if levels exceed regulatory limits. This knowledge allows operators to balance effective disinfection with potential water quality issues that can arise from chemical reactions during treatment processes.

The other options do not notably correlate with the effects of super chlorination. For instance, while chlorine residuals may be elevated, this is not the primary focus of the question. Similarly, super chlorination does not inherently increase color in water or pesticide levels, making them less relevant to this context.
