Drinking water testing is the process of analyzing water samples to ensure they are safe for human consumption. This testing checks for harmful contaminants, such as bacteria, heavy metals, and chemicals, which can pose health risks. Regular testing helps identify any issues and ensures that water meets safety standards set by organizations like the Environmental Protection Agency (EPA). Homeowners can conduct drinking water testing using kits available at stores or by sending samples to certified laboratories. Testing is especially important for private wells, as they are not regulated by the EPA. By monitoring water quality, individuals can protect their health and that of their families.
