How to Test Water Quality At Home: 3 Simple Ways

The quality of water depends primarily on the concentration of bacteria, lead, pesticides, nitrites/nitrates, chlorine, hardness , and the water’s pH. Chlorine aids in disinfecting; nitrates leached from fertilizers are harmful to infants; calcium and magnesium (“hardness”) can cause scale buildup in pipes; and water with very high pH levels (acidic water) can corrode fixtures.

There are many manufacturers of these kits, but they all function similarly. They will contain test strips that you will expose to water, causing them to change color based on the water’s mineral content. You will then match the strip’s color to a color chart.

Read the directions. In your test kit, there will be some directions. These will explain exactly how long each type of strip should be exposed to water, as well as what temperature the water should be. These directions can vary from test kit to test kit, so even if you have done this before, it is crucial to read and follow the instructions.
