18.8.1 Water Quality of Creeks and Sea waterThe water quality of the creeks and sea water with respect to pH, Conductivity,DO, BOD, Total Coliform (TC), Faecal Coliform (FC), Nitrite and Nitrate arepresented as minimum, maximum and mean value to assess the extent of waterquality variation throughout the year. DO varies from 0.3 to 8.6 mg/l. BOD isobserved in the range of 0.3 mg/l to 180 mg/l and is not meeting the desiredcriteria at all the locations except Sea Water at Puri, Paradeep and Gopalpur inOrissa. Conductivity is observed very high due to marine water insurgence and itranges from 10-65760 µmhos/cm. The Nitrate (NO 3 - ) concentrations are observedin the range of 0.0-15.39 mg/l. The Total and Faecal Coliform count is meetingthe criteria limit due to proximity of monitoring locations to sea except TC & FCin Masma Khadi at Olpad Road (9300 MPN/100ml & 4300 MPN/100ml) inGujarat and TC in Sea Water at Gopal Pur (9200 MPN/100ml) in Orissa. Thewater quality status of the creeks and sea water is presented in Annexure-I Table18.7.18.8.2 Water Quality of CanalsThe water quality of Agartala Canal, Agra Canal, Cumbarjua Canal, CuncolimCanal, Gang Canal, Gurgaon Canal, Kharda Canal, Masitawala Head Canal,Morambamarine Canal, Narmada Canal, NOAI Canal, Samarla Kota Canal,Talaganda Canal, Tulje Bagh Canal, Upper Ganga Canal and Western YamunaCanal with respect to pH, Conductivity, DO, BOD, Total Coliform (TC), FaecalColiform (FC), Nitrite and Nitrate are presented as minimum, maximum andmean value to assess the extent of water quality variation of the canals throughoutthe year. In Western Yamuna Canal DO varies from 4.9 mg/l to 8.3 mg/l andBOD observed in the range of 0.9 - 22.0 mg/l with highest value at D/s ofYamuna Nagar (22 mg/l).In other Canals, DO varies from 0 mg/l to 12.1 mg/l. The low value of DO isobserved in Agra Canal at Madanpur Khadar (0 mg/l) in Delhi; Kharda Canal atNorth 24 Parganas & NOAI Canal at North 24 Parganas (0 mg/l) in West Bengal;Talaganda Canal at Naubazar Cuttack (0 mg/l) & Atharabanki (1.0 mg/l) inOrissa; Gurgaon Canal at GC-1 near Badarpur Border (0.6 mg/l) in Haryana;Agartala Canal near Pragati Vidyabhawan (1.1 mg/l) in Tripura andMorambamarine at Thoubal (3.2 mg/l) in Manipur. BOD range is observed form0.0 mg/l to 123 mg/l and maximum found in Kharda Canal at North 24 Parganas(123 mg/l) NOAI Canal at North 24 Parganas (61 mg/l) in West Bengal; GurgaonCanal GC-1 near Badarpur Border (38.0 mg/l) in Haryana; Agartala Canal nearPragati Vidyabhawan (35.3 mg/l) in Tripura; Agra Canal at Madanpur Khadar (25mg/l) in Delhi; Talaganda Canal at Naubazar Cuttack (20.5 mg/l), Atharabanki(19 mg/l) & Jobra (7.9 mg/l) in Orissa; Morambamarine at Thoubal (8.1 mg/l) inManipur; Cumbarjua Canal at Corlim (6.2 mg/l) in Goa and Upper Ganga Canalat D/s Hari ki Pauri (5.0 mg/l) in Uttarakhand.140
