Water

Water Water that we drink doesn’t enter directly from the water source to our faucet. Many steps are taken to ensure that the water we drink and use is safe. The EPA has set up a standard by which the water must meet before entering the households throughout the country. Water quality can vary throughout the United States depending on the sources, available technology, and economic resources. In order to ensure that the water quality stays safe the EPA requires standard samples to be checked to ensure that the water is drinkable and safe. Coliform an indicator bacteria is just one of numerous amounts of bacteria that are checked in a standard check of water taken from water sources. One of the many standards that the EPA tries to maintain is less than one coliform per 100 ml of water. In order to obtain this goal the element of chlorine is added in order to kill off many of the harmful bacteria. Other tests are done in order to insure the high quality of our drinking water.
