Stretch Case Studies
River pollution is not abstract. It happens at a specific bend in a specific river, downstream of a specific drain or factory, in a specific district where specific decisions were made. Stretch Case Studies bring that specificity to Pollution Library.
Each case study is a deep, documented investigation of a real river stretch — grounded in available data, honest about what is unknown, and written to be useful for students, researchers, NGOs, and anyone working in or near that corridor.
Case studies
Section titled “Case studies” 🏭 Kanpur Stretch — Ganga One of India's most documented pollution crises — decades of tannery effluent, chromium contamination, and the long road of intervention. What the data shows and what it omits.
🏙️ Delhi Stretch — Yamuna A 22-kilometre stretch that receives nearly 80% of the Yamuna's total pollution load. The story of urban sewage, drains, governance failure, and the world's most polluted river in a capital city.
🌊 Musi River — Hyderabad A river that once defined a city's identity, now severely degraded by industrial discharge and urban runoff. A case study in rapid urbanisation and delayed response.
