If you live out where you have to depend on well water, you may think that it's always going to be in good shape, never have any contaminants, and never going to taste funny. However, as much as you would like that to be true, it isn't. Your water may taste funny or have more minerals in it than you would like. If that happens, you have some options. One of them is to use some kind of water treatment system. There are several kinds that you can use, which one you use depends on your personal preferences and what your water is like.
One thing you can try is to use a water treatment system that is a filtered pitcher. These pitchers have filters, generally made out of charcoal, that the water will run through as it comes out of the faucet and into the pitcher. The water won't run in immediately since it has to go through the filter, so you will want to make sure that you are filling it slowly enough that you don't overflow the pitcher as you are filling it. You may also want to make sure that you have more than one pitcher so that you can always have one waiting in your refrigerator with filtered water. This will work for you if you just don't like the taste of the water because that will let you have filtered water for your cooking and drinking. If you want to have treated water for your whole house, this probably isn't the best choice for you.
Another option is to use a system that goes on the tap of whatever faucet you want. These most generally show up in the kitchen, and you can turn it on and off as necessary. The water will run through the filter and come out completely filtered.
Whole House System
These systems are connected to your house's water line where it first comes into the house. There are a wide variety of whole house water treatment systems, and they all work slightly differently from each other, even though they all have the same results. If you want to have one of these systems, then you should talk to a company that installs these systems so that they can suggest what kind of system you should get for your house.
You might want to think that your well water is always going to taste good, but the fact is that you might have water that doesn't taste all that good, which means you need to come up with a way to treat it so that you can get water that tastes better.
