The 10 Best Drinking Water Test Kits You Can Order Online

There are many things to worry about daily (we lay in bed every night and count them), but the safety of your drinking water should not be one of them. If you’re concerned that your drinking water may be unsafe, put your mind at ease with an affordable and comprehensive water test kit.

Using a filter system in your home helps to remove harmful agents, but it is still likely that a small number of contaminants may remain in the water. At low levels, these chemicals may not be harmful. But at high levels, things like copper, bleach, hydrogen sulfide, lead and pH can erode pipes and cause sickness that, in cases of prolonged or heightened exposure, can lead to critical illnesses.

In areas with waterborne pathogen outbreaks, boil-water advisories may be put into effect until the source of the contamination is located and resolved. Once it’s safe to drink, it’s a good idea to use a water test kit to ensure that all the bacteria are gone.


When To Use a Water Test Kit

  • Test your home or office’s water if you notice a distinct smell or color change.
  • Test annually to ensure that your pipes and filter systems are working correctly.
  • If you have a new baby or young children in the home, they are more sensitive to contaminants in the water, so check more frequently than annually.
  • If you or someone in your home has chronic health issues, have your water checked to ensure it’s not a source of the health issues.
  • If you have a home with older plumbing or get your water from a well, test regularly throughout the year.

How To Use a Water Test Kit

Testing water in your home has never been easier. Thanks to several user-friendly tests available for purchase, homeowners can regularly test their water supply for issues and inconsistencies. The Environmental Protection Agency also has a list of labs where homeowners can send their water for a more high-tech and professional testing experience if you think your drinking water has major issues.

There are two different kinds of kits included on this list. Some will mail a collection kit to you. Simply collect the water and mail it back; a lab will test it for you. This helps reduce the risk of user error and gives more accurate in-depth results. However, these kits are considerably more expensive. Another option is to pick up an economical at-home kit, which comes with color-coded test strips for fast results.
