Since I am now purified, I am sent to stay in a holding basin. Chlorine is added to kill any remaining microorganisms and sulphur dioxide removes any excess. Some places also add fluoride to prevent cavities.
Ammonia is added before I am tested to make sure that the chlorine is stabilized. The testing is the done by a worker to guarantee that I am safe. This testing ensures that I do not contain anything that has been regulated by the EPA.
At the end of this process, there is no way to get rid of all harmful substances so some low levels are allowed such as: -Lead 0.01mg/L -Chloride 250mg/L - Fluoride 1.5mg/L - Iron 0.3mg/L
Most homes contain water softeners which use sodium or potassium to reduce the hardness of the water by replacing the calcium and magnesium ions.
After that whole process, the students of Huron Park can finally enjoy some fresh, delicious water.
Ahh so refreshing!
Water is used for many different things and is a vital part of life that all living things need to survive.
