Understanding water quality is a top concern for many people. Whether it’s water used for drinking, bathing, laundry or even swimming, you want to know whether there are potentially harmful contaminants in your water.

There are many water testing kits available to help you understand the quality of your water. The most thorough kits require you to mail in samples for a full report on dozens of contaminants. More basic testing can be done with an at-home kit that doesn’t require you to mail in samples and wait for results. There are also water testing kits that evaluate only lead, bacteria or a limited set of common contaminants. These are usually less expensive than kits that include more extensive testing.

Whether you want to test your city water supply, well water supply, or pool water, we have the best water testing kits listed here to meet your needs.
