Yamuna remains on the list of worst polluted
Source: The Hindu, New Delhi, Date: , 2009
Inestimable efforts and huge sums of money have
gone into resuscitation of the Yamuna, but the river within the limits of the
city remains the “worst affected”. The river has again found mention in the
list of the worst polluted ones drawn up by the Central Pollution Control
Board. According to the latest status of water quality in India-2007 released
by the Board, the Yamuna’s water quality at Okhla and Nizammudin bridges has
been described as the worst affected. As per data on the water quality of water
bodies and groundwater locations, it was placed seventh on the list of rivers
with the highest bio-chemical oxygen demand, one of the most important
indicators of pollution. The report says the level of dissolved oxygen is
observed more than 4 mg/l in river Narmada, Brahmaputra, Mahanadi, Brahmani,
Baitarni, Subernarekha and Beas throughout the year whereas values less than 4
mg/l are observed in stretches of the Yamuna (0.0 mg/l) and at few locations
downstream of urban settlements due to discharge of untreated and partially
treated wastewater, which is responsible for high oxygen demand. The report
goes on to say that the water quality of the Yamuna has deteriorated at Paonta
Sahib, Kalanaur, Sonepat, Palla, Nizammudin, Okhla, Mazawali, Mathura, Agra,
Bateshwar, Etawah, Juhika and Allahabad and the Western Yamuna Canal downstream
of Yamuna Nagar at Damla is “grossly polluted due to municipal and industrial
waste water disposal”.
