This study investigates the impact of groundwater contamination on educational outcomes in India, using variations in the geographical coverage and timing of safe government piped water schemes. The study is based on survey data from public schools in Assam, one of India’s most groundwater-contaminated regions. It is found that prolonged exposure to unsafe groundwater is linked to increased absenteeism, grade retention, and lower test scores and CGPA. Additionally, the researchers use a nationally representative household survey to study the effect of arsenic contamination.
