water test kits are an easy way to gain valuable insight into the quality of the water you rely upon for drinking, cooking, bathing, laundry, and more. These kits generally use either test strips submerged into a water sample or drops that react with various contaminants if present. Other testing kits require you to mail a submission into a laboratory. While these tests are usually the most comprehensive, they're also the most expensive.
If you’re concerned about the safety of your drinking water, a water testing kit is an easy way to find out if there are contaminants in the water. According to Rick Andrew of NSF International’s Global Water Program, the primary contaminants found in drinking water are lead, arsenic, bacteria (coliform), cysts and viruses, chlorine, chloramine, chromium, fluoride, nitrates and nitrites, PFOA and PFOS, Total Trihalomethanes (TTHM) and Volatile Organic Compounds (VOCs).
