Private Individual Water Testing Services

What's in Your Drinking Water? Homeowners of private drinking water systems are responsible for the testing and quality of their own drinking water, unlike regularly tested and regulated public water systems. (If you are on public water, request your annual water quality report from the company listed on your monthly water bill.)

Testing your individual water system is the only way to be sure your water is safe to drink.
