Concerns

Yamuna, from its origin at Yamunotri in Himalayas to Wazirabad barrage, travels by carrying "reasonably good quality" water. Between Wazirabad and Okhla barrage, 15 drains discharge sewage rendering the water quality after Wazirabad barrage severely polluted with biochemical oxygen demand (BOD) values ranging from 14 to 28 mg/L and high coliform content. Causes of pollution are municipal disposal sites, run-off from the commercial and industrial sites, soil erosion resulting from deforestation occurring to make way for agriculture along with resulting chemical wash-off from petrochemical fertilizers,
