Explanation:

The fight of human beings to achieve the goal of getting pure water, instead of water polluted by different factors that affected its quality, has been one that has taken ages. Since the earliest human settlements, to today, mankind has sought to find, conduce, and purify water from any harming elements that might affect the population´s health. Although in general the achievement in the 19th century, of finally purifying water, accomplished the development of human civilizations and reduced the risk of major public health issues, it also caused a problem; by fighting to reduce the presence of bacteria that reached the water sources from fecal matter, many of which are part of the normal microbiota in human intestines, man achieved the elimination of part of this normal microbiota, which has also led to certain inbalances in the gastrointestinal systems.
