水中通常存在的细菌大致可分为三类：第一类是天然水中存在的细菌。普通的是荧光假单孢杆菌、绿脓杆菌，一般认为这类细菌对健康人体是非致病的。第二类是土壤细菌。当洪水时期或大雨后地表水中较多。它们在水中生存的时间不长，在水处理过程中容易被去除。腐蚀水管的铁细菌和硫细菌也属此类。最后一类是肠道细菌。它们生存在温血动物的肠道中，故粪便中大量存在。水体中发现这类细菌，可以认为已受到粪便的污染。致病性肠道细菌有沙门氏杆菌(伤寒和副伤寒菌)、志贺氏菌(痢疾菌)和霍乱弧菌等。
Bacteria commonly found in water can be roughly divided into three categories: the first category is bacteria in natural water. Common are Pseudomonas fluorescens and Pseudomonas aeruginosa, which are generally considered to be non pathogenic to healthy human beings. The second category is soil bacteria. There is more surface water during flood or after heavy rain. They do not exist in water for a long time and are easy to be removed in the process of water treatment. Iron bacteria and sulfur bacteria that corrode water pipes also belong to this category. The last category is intestinal bacteria. They live in the intestines of warm blooded animals, so they are abundant in feces. If such bacteria are found in the water body, it can be considered that they have been polluted by feces. Pathogenic intestinal bacteria include Salmonella (typhoid and paratyphoid), Shigella (dysentery) and Vibrio cholerae.
