Well Water Testing

Sometimes, there may be some invisible substances such as viruses and bacteria in the well water even though it looks very clean and tastes very good. If your drinking water is from a private well, it can directly affect your health. So, it is necessary to pay close attention to well water at different periods, especially when the conditions in the vicinity of the well change significantly, such as floods, large storm, new buildings or industrial activities, the water quality of the well including smell, color, taste, etc. will change significantly. Regular testing of well water can identify problems of well water in a short time and ensure that the well water is suitable for humans and animals.

STEMart can provide you with a variety of testing services to notice a change in your water quality.
