Sanitation was becoming better understood in the 1800s. They were beginning to realize that human and animal waste, along with uncared for garbage, were a major contributing factor in viral and bacterial epidemics. As people became healthier, employment for manufacturing was on the rise. The large factories did not have a full understanding of the importance of clean waterways and air. They would dump biproducts directly into lakes and rivers. The rivers were overcome with heavy metals and other dangerous chemicals. These practices continued into the early 1900s. When the rivers started becoming so polluted that they would catch fire, people started to wake up to the pollution problem.
