Water pollution poses a significant threat to global public health, particularly in developing regions where inadequate infrastructure, poor sanitation, and industrialization exacerbate the risks. Waterborne diseases, such as cholera, dysentery, and diarrhea, continue to result in high mortality rates, especially among vulnerable populations, including children and low-income communities. Climate change further exacerbates the challenges by altering water systems and enhancing pollution levels, thereby increasing the prevalence of waterborne illnesses. School-based environmental education plays a crucial role in mitigating these health risks by raising awareness among children and their communities about water conservation, hygiene practices, and pollution prevention strategies. Effective school curricula that integrate environmental education can foster long-term behavioral changes, encouraging the adoption of better water management practices and improved sanitation. Involving students in community outreach and water quality monitoring further enhances public health outcomes by promoting proactive engagement in solving local water pollution issues. However, challenges such as limited resources, cultural barriers, and the need for interdisciplinary collaboration must be addressed to enhance the effectiveness of these programs. It is concluded that, to reduce the public health burden of waterborne diseases, governments should invest in water infrastructure, prioritize environmental education in schools, and promote interdisciplinary collaboration. A key recommendation is to integrate environmental education into school curricula, enabling students to contribute to water conservation efforts and advocating for better water governance. This holistic approach can significantly improve public health outcomes and ensure access to safe water for all.
