To ensure that water sources in developing countries are safe for human consumption and ecological sustainability, water quality monitoring is an important process. It includes routine evaluation of the physical, chemical, and biological state of water sources. Concerns about water contamination and waterborne diseases like cholera and typhoid fever are a common occurrence in many developing nations. This situation is due to factors such as limited clean water access, industrial pollution, fast urbanization, and insufficient sanitation systems. Water quality monitoring effectively aids in the early detection of pollution, bolsters public health protection, and guides decisions on water management.
