It is the section 3.1.1 coming from The World HealthOrganization’s report—Water Safety in Distribution Systems. It shows a biological hazard which has the capacity to harm the water distribution system.In the section, this description effectively introduces the resource of themicroorganisms is the faecal contamination, the reason it survives is the protection of biofilms, and the bad influences it causes are various diseases. Then, it introduces a major way to control this hazard. Based on the content, I find it’s a very necessary part in the whole document because hazard has the potential to harm water system, and microbial hazard is the mostpotential type in it. So, if there isn’t this description, readers would not know the major menace, and they can’t get how to protect the water distribution system.
