When you use well water instead of city water, you need to check the filter so you don't have nasty, dirty water coming in your home. There are a lot of people that say well water tastes better than the town's water does because it tastes like natural water. You need to have someone put the chlorine in it for you so you don't over do it because too much will be bad. You will not have a water bill so it saves you a lot of money. To be on the safe side, you need to get a new filter every month and change them to keep your water clean and healthy for you to drink.
When I was younger we lived in a house that used well water, and we liked it that way. It was clean and cold and it tasted great. You have to keep it cleaned or you can get bacteria, and it will be hazardous for your health. You also have to test it so that you can use it to drink and to make sure it is safe to use in baby formula or children's drinks. Make sure there is nothing in it. They used to have them everywhere. They would dig a hole into the ground and pump the water out through a pipe, and it came out of a well. The well water came from spring water that is in the ground so you need to have it checked for your safety because it might have lime, silica, iron, and sulfur in it. That way you need to be careful and have someone test it before you drink, cook, or take a bath in it.
When it is checked right then it can be ok to use it, but that's if they say so. Don't let this scare you, because this is only for your safety and it is good to do when you have these. You have to use chlorine bleach in it to clean it really well and to get the bad stuff that could be in it. Treating the water will keep the bacteria out of the water for a certain period of time. If it is not taken care of, then you might have an odor or discoloring in the water. This means to not drink it or use it because it is contaminated, and it is dangerous for you. So if you like to use well water in your house then you need to do this.
