One of the causes of taste and odor problems in water is?

Taste and odor problems in water can arise from various factors, with algae being a significant contributor. Algae can proliferate in water sources due to nutrient enrichment, especially in warm weather. When they die and decompose, they release organic compounds that can lead to unpleasant tastes and odors, such as a musty or earthy flavor. This is particularly common in surface water sources, where conditions are more favorable for algal blooms.

Chlorine is used as a disinfectant in water treatment, and while it might impart a certain taste or smell, its primary purpose is to eliminate pathogens rather than to cause taste or odor problems. Heavy metals and fluoride are typically more associated with health concerns and may not directly cause taste and odor issues to the same extent as algae do.
