What can cause rates and odors in storage tanks and distribution systems?

Algal growth is a significant factor that can lead to undesirable rates and odors in storage tanks and distribution systems. When conditions are favorable—such as warm temperatures, sunlight, and adequate nutrient levels—algae can proliferate rapidly within the water. This growth can lead to an increase in organic material, which can then result in the production of taste and odor compounds, such as geosmin and 2-methylisoborneol (MIB). These compounds are often detected by the human palate and can create off-putting tastes and smells in the water supply.

In addition to causing unpleasant sensory issues, algal blooms can also lead to additional concerns, such as the production of toxins, which may pose health risks to consumers. Management strategies often aim to limit algal growth by controlling nutrient levels, ensuring proper treatment processes are in place, and monitoring for signs of blooms to maintain water quality in both storage and distribution systems.

In contrast, while high mineral content may affect water quality and taste, and excessive chlorine treatment can lead to taste issues as well, they typically do not result in the characteristic odors associated with algal growth. Regular flushing of the system is generally a maintenance practice used to enhance water quality and reduce sediment build-up, not
