Fungi

Fungi are a diverse group of known organisms that include yeast, moulds and mushrooms, found in various environments, including water. In water, fungi can grow on organic matter, such as leaves, wood, or other debris, that has fallen into the water, with some types causing health problems if ingested, particularly for people with weakened immune systems. Additionally, some fungi can produce toxins that can contaminate water and cause harmful health effects, but a proper treatment process can help remove fungi and their associated contaminates from water sources.
