How OfTen Should I Test My Water?

The U.S. Environmental Protection Agency (USEPA), in some publications, seems to indicate yearly for private well water, for public systems it will depend on your own preference. Perhaps the best answer is what you as a consumer feel comfortable with.

What Should I Test for?

This is the most frequently asked question. Basically, you should test for any parameters that are of concern to you and may affect your health. There are many things that can be in water that are health related and testing for all of them can be very expensive. This is why we have partnered with Tap Score as an excellent overall water quality screen.

Free Water Testing?

Beware of free water tests! e-WaterTest.com has spent a large amount of money to purchase laboratory equipment and train qualified staff to test drinking water in accordance with USEPA testing methodologies. There are many water testing offers on the internet that are being less than honest about the way they perform their analysis, e-WaterTest.com performs a full range of in-house testing using state of the art instrumentation and equipment.
