Iron bacteria are known to produce compounds that can lead to taste and odor problems in water systems. These bacteria thrive in environments where iron is present, often resulting in the formation of rust-colored deposits and biofilms. As they metabolize iron, they can release organic compounds that have an unpleasant taste and odor, which can affect the sensory quality of drinking water.

While coliform bacteria are indicators of fecal contamination and can have serious health implications, they do not typically contribute to taste and odor issues. Heterotrophic bacteria, on the other hand, can grow in drinking water and are often associated with biofilm formation, but they do not specifically produce the taste and odor compounds that iron bacteria do. Thermophilic bacteria, which thrive at high temperatures, are more relevant in certain industrial applications and can pose risks in other contexts, but they are not generally a concern in the context of taste and odor in water systems.

Thus, iron bacteria are the primary concern when it comes to the taste and odor quality in drinking water systems.
