  • First, get a copy of our annual water quality report before you pay to test your water. This report will tell you which contaminants, if any, have been found in your drinking water and at what level. You are always free to conduct additional sampling for your residence; however, in most cases this is not necessary.

    Without knowing what to look for, the cost of testing drinking water on a hit or miss basis can be very high. Depending on how many contaminants you test for, a water test can cost from $15 to hundreds of dollars. If you test for all possible contaminants, testing costs reach into the thousands of dollars.
