Cleaning materials such as toothpaste, dish soaps, and other at home cleaning chemicals that may contain triclosan can cause problems for water treatment plants. In this article it is discussed that when a person is using antimicrobials to kill germs at home, and when the chemical is washed down the drain it has been showing up in the sewage sludge. The problem with this is that the bacteria that breaks down the sewage has been ingesting the triclosan and causing a decrease in the amount of methane given off by the microbes. The decrease in methane production means a decrease in waste break down. As a end result this is causing an issue with the water treatment plants.
