Background
The Chambal sanctuary supports gharial, gangetic dolphin, and migratory birds dependent on clean water.
Current Situation
Illegal sand mining raised turbidity and altered channel morphology through the early 2020s.
Environmental Impact
Bi-monthly sampling at 18 GPS-tagged points; lab analysis for nitrates, phosphates, and coliform.
Actions Taken
Nitrate levels dropped 34% at upstream points two years after enforcement intensified.
Results
Agricultural runoff still elevates phosphates in monsoon; two downstream points remain impaired.
Future Recommendations
Continue community watchdog reporting; restore riparian buffer strips on private farmland edges.
