This well pumps the water up from the aquifer. If the well is in the city, the water will go through the water treatment plant. If the well is in a rural area, the water may be filtered, but some pollution may remain. When you want a drink of water, you turn on the faucet. But before water comes out of a faucet, it goes through a water treatment plant.
Water is taken out of a river, lake or reservoir.
There, chemicals are added to take out yechy things and help get rid of any bad taste or smell. Once everything is out of the water, a little bit of chlorine is added to keep the water from growing bacteria before it gets to your home. Tell your family to buy only as much as they can use. Buy least toxic as possible. Give leftover cleaning supplies to others who need them.
