Water pollution, predominantly caused by human activities, represents a major global public health challenge. This study employs Pearson's correlation coefficient to analyze the relationship between water quality and population health. The analysis reveals a moderate negative correlation (r = -0.3818) between the incidence rate of waterborne diseases and life expectancy, confirming the significant impact of water quality on public health outcomes. Waterborne diseases such as diarrhea, cholera, and typhoid demonstrate direct associations with unsafe water access and inadequate sanitation conditions. These diseases disproportionately affect vulnerable populations, generating substantial economic and social costs. Primary contributors to water pollution include industrial discharges, intensive agricultural practices, domestic wastewater, mining operations, and deforestation. Addressing this complex challenge requires implementing sustainable water management policies, enhancing sanitation infrastructure, and promoting preventive practices. An integrated approach across water, health, and environmental sectors is crucial to ensuring safe drinking water access and mitigating water-related disease burdens. Strategic investments in sustainable solutions and public awareness campaigns will not only protect public health but also advance progress toward Sustainable Development Goals (SDGs), particularly those related to health (SDG 3) and water security (SDG 6).
