If you have a private well, then water quality testing is very important for you and your family. Some contaminants in drinking water have been linked to cancer, toxicity, hyper-tension (excess sodium), posing risk to human health. Many contaminants often have no taste, odor or color. Their presence can only be determined by laboratory testing.
When taking any sample, Watch® recommends that it be taken after a heavy rainstorm. These events tend to highlight conditions of improper well construction or poor soil filtration.
