Who does water quality testing for my drinking water? That depends on your water source.
If you pay a water bill to a municipality or water utility, they are legally bound to follow federal and state water quality guidelines. This includes regular inspections from the federal Environmental Protection Agency and state enforcement agencies. Water quality is tested and regulated at the source level when it enters a water treatment plant, inside the plant itself, when it leaves the plant and when it is in the pipes leading to your home.
Once the water passes the water meter, or if you have a private source, the responsibility for water quality falls to you. The EPA recommends annual testing of well or spring water that is used as a primary water source. Some of the things you should test for include coliform bacteria, nitrates, total dissolved solids, and pH levels.
If the taste or appearance of your water changes, you should get it tested right away whether you are on a municipal system or a natural source. Call the Geiler Company if you are on a municipal system so we can determine if you have a problem with your plumbing or water source as it enters your home.
If you have a natural source of water, your local health department will have records of any possible contamination in your area. You need to know what possible contaminants might be present to know what to test for.
Even if everything seems fine with your natural source of water, the EPA recommends testing more often than once a year if you have small children or elderly adults in your house or if someone is pregnant or nursing.
