A water testing kit can help you gain valuable insight into the safety of your water supply. Whether you’re using it for drinking, cooking, bathing, or laundry, it’s important that the water is clean and free from harmful contaminants.

“Contaminants can vary by region and water source, and it is important to sample for contaminants that are common in your area,” advises John Erickson, Technical Director of Community Water Center. For example, iron and bacteria are more likely to be present in well water, while arsenic and lead are often associated with city water issues.1

The good news is that there are a variety of water testing kits on the market that allow you to identify any potential problems. Many water testing kits are designed to be performed at home, offering results in as little as five minutes. Both affordable and easy-to-use, test strips are the most common water-testing method, but there are also digital options as well as reagent drop tests. 

More advanced tests require you to take a water sample at home and submit it to an EPA-certified lab for testing. The cost of a lab test is significantly higher, and results may take a week or more to receive. However, you will get a more accurate, comprehensive analysis. 

We researched dozens of water testing kits, evaluating them on water source compatibility, testing procedure, which contaminants they screen for, accuracy, and the number of tests included per kit.
