Water contamination is a scary thought. Unless your water is severely discolored or has a particular taste, you might assume it’s acceptable to use. However, your water could be contaminated with bacteria, lead, or something else and you wouldn’t know until it began affecting your health. This is why testing your water is so important. You can purchase a home water test kit to get a pretty good idea of what’s in your water. The best water testing kits are relatively inexpensive and will give you the key information about what’s in your water and whether or not you need further investigation. If you’re looking for the best home water test kit, this guide is for you!

A drinking water test kit is just what it sounds like. In the simplest definition it is a test that examines your water. There are a variety of kits, some are more specific and include more contaminants than others. According to the EPA, a person should check their water annually for bacteria, dissolved solids, and nitrates, among other things. While your local water plant will treat and test your drinking water, keep in mind that the testing is done before it leaves the treatment plant. It still has to travel from the plant to your home and could go quite a long way, coming in contact with bacteria, lead piping and other contaminants along the way.

Importance of Testing Your Water

It goes without saying that testing your water is a beneficial and necessary task. There are several events that would suggest that you need to find the best water test kit for your situation. For example, the EPA recommends testing your water if someone in your home is pregnant or if you have a new baby. If you’ve had a gastrointestinal illness that was unexplained, or you notice that your water has a scent or taste that it does not normally have are other reasons to seek out a water test kit.

Some other reasons include:

Safety – Most contaminants are noticed until it’s too late and some form of damage is already done. If your water has lead in it, you might not initially know it. However, eventually you would display symptoms of lead poisoning, depending on the levels in your water. By taking the time to determine the best water testing kit for you, you’ll be able to drink and use your water knowing exactly what is in it. Once you know what’s in your water you can take the steps necessary to improve the quality.

Peace of Mind – If you have small children, animals, or even plants you want them to have the best quality water possible. There are far too many contaminants that can harm the development of pregnant women and children. Testing your water ensures that you know it’s safe or that you can work to fix your water if it’s not.

It’s Time – It’s easy to forget about the need for water tests if nothing seems wrong. That’s why it’s good to plan your testing around events. We’ve discussed family growth and the addition of young children already. That’s one important type of event. Another could be when home improvements are done in your home. If construction work has been done, it can affect the plumbing in your home. This could mean nothing, but you could end up with lead or something else in your water that has come from the pipes being affected from the work that has been done. Annual testing is always a great idea, but planning for tests around big life changes is another way to ensure that the testing is done frequently for the safety of everyone in your home.
