of deaths. Additionally, he conducted a statistical analysis comparing the number of cholera deaths in different areas with varying water supplies. This analysis showed that both the number of deaths and especially the mortality rate were significantly higher among those supplied by the Southwark company (Aschengrau & Seage, 2008).

Drawing on his research and discoveries, he formulated a theory concerning the origin and spread of contagious illnesses. He postulated that contaminated water was the means through which cholera was transmitted. Furthermore, he actively supported the afflicted community by advocating for improved water supply, even before identifying the actual agent responsible for cholera. In 1849, he released a publication entitled "On the Mode of Communication of Cholera."

In order to prevent cholera, he proposed various methods. Among these recommendations was the importance of maintaining a clean and uncontaminated water supply for drinking purposes, free from "cesspools, house-drains, or sewers" (Aschengrau & Seage, 2008). If there is any suspicion of contamination, it was advised to boil and filter the water before consumption.

John Snow revolutionized epidemiology with his notable contributions, which are regarded as a major progress in the field. His remarkable achievements include adeptly organizing his findings, conducting natural experiments, and quantitatively analyzing the collected data. These combined efforts firmly establish the link between cholera outbreaks and the Drinking Water Company.
