Haines, noted economist at Colgate University, observed that before 1920, the mortality of urban dwellers was far higher than the mortality of people living in rural areas. In 1900, for example, the life expectancy of rural white males was 10 years higher than that of urban white males. 4 years in 1930. 6 years. 34 For infants, the penalty for urban living was far worse. In 1890, excess mortality for urban infants (compared with the mortality of rural infants) was 88 percent. By 1900, it had dropped to 48 percent, and it declined further through the early twentieth century.

The water supply from the Merrimack River was grossly contaminated with sewage. By 1896, Lowell had changed its water source from the river to a series of wells that tapped an uncontaminated supply. The 1903 epidemic occurred when river water from a system supplying industrial water was used to fight a fire, and a valve separating the potable supply from the fire-fighting supply failed. 53 More than fifteen years later in Peabody, Massachusetts, 1,500 people were sickened during a virulent waterborne outbreak of gastroenteritis.

The plan was submitted to the mayor and city council in 1855. 86 It was not until two years later that consulting engineer Julius W. 87 As part of his plan, Chesbrough considered four options for sewage disposal. ”88 The first option was deemed the best and least costly. However, the fourth option was eventually implemented when the flow of the Chicago River was reversed in 1900. The choice not to implement the third option was based on the miasma theory of disease.  . ”90 Sewers were dutifully constructed according to Chesbrough’s plan, and most of the foul wastes were dumped into the Chicago River.
