What is measured in a water quality test? A lot of things.
Water quality tests are important in a number of ways. The Environmental Protection Agency has minimum standards for drinking water that must be met at every step of the process. That starts at the water source, extends through the water processing plant and delivery system to your home. State and local regulations also apply to water quality.
So what is measured when determining water quality? New homes and existing wells are tested for the presence of coliform bacteria, which is very important. The best known coliform to many people is e. coli, which can make you very sick. Your water should test negative for coliform.
There are a number of other properties to test when determining water quality.
If you start noticing a strange taste from the tap water at your home, or if you get more than you expected from the taste of the water somewhere else, there are a number of possibilities. The first and most obvious answer is that there is something in the water that shouldn't be. But what is it? That depends on the taste.
