There is no substitute for pure water. Whether you’ve seen a change in your water quality, or are thinking about buying property, we can help you assess drinking water. We offer biological and chemical tests separately and a Home Diagnostic Test, which provides a full spread of biological and chemical tests. To compare each of these tests side-by-side, see our Test Grid.
