Water testing is the process of analyzing water samples to determine their quality and safety. This testing can identify contaminants such as bacteria, heavy metals, and chemicals that may pose health risks. It is essential for ensuring that drinking water meets safety standards set by organizations like the Environmental Protection Agency (EPA). Various methods are used for water testing, including laboratory analysis and at-home test kits. Regular testing helps monitor water quality in wells, rivers, and lakes, ensuring that communities have access to clean and safe water. Proper water testing is crucial for public health and environmental protection.
