The type of analysis you choose should be based upon your specific concerns, your water source and what contaminates may potentially be in the water. If you are on a city water supply, you may want to test for the by-products of disinfection and heavy metals as they are likely to be in the water. If you are on a private well it is important to test for bacteria as that is a common contaminant, as well as naturally occurring contaminants such as arsenic, radon, barium, iron and manganese. For information regarding all of our home water testing packages including sample test reports, sampling instructions and information sheets (contaminant lists), please visit our products page.
