Groundwater testing is the process of analyzing water found underground to determine its quality and safety. This testing helps identify contaminants such as bacteria, heavy metals, and chemicals that may affect human health and the environment. Samples are usually collected from wells or springs and sent to laboratories for detailed analysis. Regular groundwater testing is essential for communities that rely on wells for drinking water. It ensures that the water meets safety standards set by organizations like the Environmental Protection Agency (EPA). By monitoring groundwater quality, we can protect public health and preserve vital water resources.
