Answers
Explanation:
Water is a natural carrier of disease-causing pathogens, including many that impact human health, such as E.coli and Giardia. Over the course of human history, various cultures found that treating water could improve human health. The ancient Egyptians, for example, are believed to be the earliest adopters of advanced treatment techniques, using alum to coagulate water and aid in improving clarity and filtration. However, widespread water treatment did not start until the early twentieth century.
In 1906, the number of annual typhoid fever cases in the U.S. resulted in it being declared a nationwide epidemic. Increasing cases of waterborne illnesses prompted many large U.S. cities to filter water on a large scale. With the addition of filtration to drinking water, the number of annual typhoid fever cases dropped from 10,000 to approximately 1,000 in less than 10 years.
However, filtration alone was not adequate to reduce the rate of illnesses. In the mid-to-late 1800s, chlorine was sporadically used to control infection in hospitals and drinking water. In 1914, the U.S. Department of the Treasury enacted a standard requiring a maximum of two coliforms per 100 mL in drinking water, effectively ushering in the modern age of disinfection in the U.S. Chlorination is credited with virtually eliminating waterborne epidemics and with increasing life expectancy by 50%. Disinfection, with its ability to kill up to 99.99% of certain pathogens, is arguably the single largest advancement in the improvement of human health in the history of humankind.
