Poor environmental quality poses significant health risks to individuals in their daily lives, including a range of waterborne diseases such as diarrhea. So, the study highlights the importance of raising awareness about the health risks associated with consuming inferior-quality environmental goods through education. This study investigates the influence of formal education on the adoption of water purification methods among low-income households in Noida, India, and its effects on the incidence of waterborne diseases. The research aims to understand how educational attainment impacts the use of purification techniques such as straining method, water boiling method, non-electric water purifier, and electric purifiers. Primary data is collected through surveys. Multinomial logit models and probit models have been used to analyze the data. The findings reveal a significant positive relationship between education levels and the likelihood of adopting effective water purification methods, resulting in a reduced incidence of waterborne diseases, particularly diarrhea. Therefore, this study underscores the critical role of education in promoting health-protective behaviors and offers valuable insights for public health policy and interventions aimed at ensuring access to clean drinking water in urban India.
