You may wonder why you would need to have your water tested. Especially if it doesn’t taste or smell bad or have any noticeable discoloration or cloudiness. The fact is that many common contaminants that are found in drinking water do not cause a change that is detectable by smell, taste, or sight.
However, these contaminants could be causing minor to major health issues for your family members and ultimately your family’s health is most important. In addition to the possible health issues that could be caused by elevated levels of certain elements in your drinking water there are some that cause damage to your home as well. For instance, elevated levels of certain minerals can cause corrosion of your pipes, staining of bath tubs, showers and sink, and various other issues within your home. These can lead to more severe problems such as leaking and mold. Therefore, even if you water tastes good and looks clear it is important to have it tested on a regular basis to keep your family and your home safe. Only a thorough test for all possible contaminants, diseases, chemicals, and minerals can tell you what is lurking in your water or if it is really safe to drink.
What do Water Tests Check For?
Water tests test for various microorganisms, disinfection byproducts, disinfectants, inorganic chemicals, organic chemicals and radionuclides in your drinking water. These contaminants can cause anything from staining of your clothes to various illnesses including cancer. The EPA has set guidelines for the levels of these substances that are safe for your health and the maintenance of your home, however, most states have determined their own levels based on those set by the EPA. When you have your water checked by a state certified laboratory and a certified inspector they will give you a comprehensive list of the items they tested for and levels found in your water. This report will also include whether or not the levels of each that were found in your water are safe or not. This will give you a good idea as to whether your water needs to be treated and what you and your family may have been exposed to. Each state may test for different contaminants in your water, in New England a water analysis will test for the following:

When Should You Have Your Water Tested?
There are several determining factors that inform when you should have your water tested. First and foremost is whether you have a public or private water supply to your home. Most Americans have public water. If you have water that is provided by the city, they will test your water once a year and send you a report that will let you know if your water is safe or not. Therefore, if you have public water is not necessary to have your water checked privately unless you suspect that there is lead in your household plumbing, someone in your house is pregnant or you planning to install a household water treatment system. On the other hand, if you have a private water supply ie. a well you will need to follow different guidelines. If this is the case you should have your water tested at least once a year. You may need to have it tested more frequently if someone in your home is pregnant, if you notice a strange odor or color in your water, or you know of a local contaminant that might affect your water source. If any of these factors apply you should have your water tested as soon as possible.
How Do You Have Your Water Tested?
There are a few different ways that you can have your water tested. If you only need a test for nitrates and bacteria often your county health department will test the water for you. However, if you want a full comprehensive test there are only two ways to get this done. The first is by buying a self-test and collecting a sample of your water to be tested. You can purchase these test kits at your local home improvement store. Where this is the cheapest option it may not be the most accurate or easiest choice. If you want to be sure that your water is accurately tested (especially if you suspect there are contaminants in it) it is best to have a state certified lab test your water. You can do this by contacting a state certified home inspector that is qualified to collect samples and have your water tested. As with anything that has to do with protecting your family’s health it is better to be safe than sorry!
