EXECUTIVE SUMMARYThe water quality data on rivers, lakes, ponds, tanks and groundwater locations beingmonitored under the network is evaluated against the water quality criteria and themonitoring locations in exceedence with respect to one or more parameters are identifiedas polluted and require action for restoration of water quality. The locations on rivers,lakes, ponds, tanks and groundwater not meeting the criteria are summarized briefly inthis chapter.The monitoring results obtained during 2011 indicate that organic pollution continues tobe the predominant pollution of aquatic resources.The organic pollution measured interms of bio-chemical oxygen demand (BOD) & Coliform bacterial count gives theindication of extent of water quality degradation in different parts of our country. It isobserved that nearly 63% of the observations are having BOD less than 3 mg/l, 19%between 3-6 mg/l & 18% above 6 mg/l. Similarly Total & Faecal coliform which indicatepresence of pathogens in water are also a major concern. About 50% observations arehaving Total Coliforms and 69% observations are having Faecal Coliform less than 500MPN /100 ml.WATER QUALITY OF RIVERSHIMALAYAN RIVERS (SATLUJ-BEAS-GANGA-YAMUNA-BARAK) CATCHMENT• Indus Catchment- Water quality of River Beas at upstream Mandi in Himachal Pradeshand River Satluj at Downstream Budhanala Confluence, Ludhiana; Boat BridgeDharmkotnakodar Road; Jalandhar; U/s Head works Ropar; Downstream of Zenith;Downstream of East Bein and Upstream Budhanala in Punjab; River Chunt Kol (MaulanaAzad Bridge) and River Tawi at Jammu U/s (Tawi Bridge) in Jammu & Kashmir founddeteriorated and degraded as compared to stipulated requirement.• Ganga Catchment- The water quality of River Ganga does not meet the criteria atHaridwar D/s; U/s Vindhyachal; Kanpur U/s (Ranighat) & D/s (Jajmau Pumping Station);Bithoor (Kanpur); Kannauj U/s (Rajghat) & D/s; Varanasi U/s (Assighat) & D/s (MalviyaBridge); Howrah-Shivpur; A/c R.Song Nr Syanarayan Temple D/s Raiwala; KachhlaGhat; Narora (Bulandsahar); U/s & D/s Anoopshahar; Allahabad (Rasoolabad); AllahabadD/s (Sangam); Kadaghat, Allahabad; D/s Mirzapur; Garhmukteshwar; Trighat (Ghazipur);Dalmau (Rai Bareilly); Kala Kankar (Raebareli); Baharampore; Diamond Harbour;Dakshineshwar; Uluberia; Garden Reach; Upper River D/s Roorkee; Nabadip andSerampore.The water quality of River Yamuna is not meeting the criteria at Mathura U/s& D/s, Vishramghat (Mathura), Mazawali, Agra U/s & D/s, Okhla Bridge (Inlet of AgraCanal) & Nizamuddin, Bateshwar, Kesighat, Vrindavan, Shahpur, Etawah, Juhika B/cwith Chambal (Etawah), Allahabad D/s (Balua Ghat), U/s Dak Patthar,Wazirabad andSonepat.The water quality of tributary streams River Suswa, Gola, Ramganga, KalinadiI
