14.2 Water Quality Monitoring in Godavari BasinThe water quality monitoring of the River Godavari are being done in the basin bythe State Pollution Control Boards of Maharashtra, Andhra Pradesh, MadhyaPradesh and Orissa. The monitoring locations are on main stream of Godavari(35) and on tributaries are Manjara (Manjira), Maner, Nira, Wainganga, Wardha,Kolar, Kanhan, Purna, Indravati, Sankhani, Nakkavagu,Vamsadhara, Darna,Bindusar, Penganga, Vena, Kinnersani and Sabari. The ranges of water qualityobserved in Godavari basin with respect to Temperature, pH, DO, Conductivity,BOD, Nitrate, Nitrite, Total Coliform (TC) and Faecal Coliform (FC) arepresented as minimum, maximum and mean value to assess the extent of waterquality variation throughout the year.14.2.1 Water Quality of River GodavariThe water quality of River Godavari indicates that the DO value ranges from 1.2-12.2 mg/l. The minimum value of DO (1.8 mg/l) is observed at Kapila- GodavariSangam in Maharashtra. Other locations having low DO are Tapovan (1.8 mg/l),Nasik D/s (1.9 mg/l), Jalna Intake Water Pump House, Shahabad (2.3 mg/l),Saikheda (2.7 mg/l), U/s of Aurangabad Reservoir (3.4 mg/l) and Hanuman Ghat,Nashik City (3.8 mg/l) in Maharashtra. The BOD values ranges from Nil-37 mg/land the higher values are observed at Kapila- Godavari Confluence Point atTapovan (37.0 mg/l), Nasik D/s & Tapovan (28.0 mg/l), Jalna Intake Water PumpHouse at Shahabad (18.7 mg/l), Panchavati at Ramkund (16.0 mg/l), SomeshwarTemple (14.5 mg/l), Hanuman Ghat at Nashik (13.5 mg/l), Saikheda (12.5 mg/l),Jayakwadi Dam at Aurnagabad & D/s of Paithan at Pathegaon Bridge (12.0 mg/l),Dhalegaon (10.0 mg/l), U/s of Gangapur Dam at Nasik (9.0 mg/l), U/s of Paithanat Jayakwadi (8.0 mg/l), Latur Water Intake Near Pump House at Dhamegaon &Nanded (7.4 mg/l), U/s of Aurangabad Reservoir at Kaigaon Tokka (7.2 mg/l),Raher (7.0 mg/l) and Nandur- Madmeshwar Dam (6.0 mg/l) in Maharashtra andGodavarikhani at Karimnagar (7.8 mg/l), D/s of Ramanugundam (7.7 mg/l),Ramagundam D/s Near FCI Intake Well at Karimnagar (6.4 mg/l), Basara atAdilabad (4.0 mg/l), Mancherial & Mancherial B/c of Rallavagu (3.6 mg/l) andKamalpur D/s at Warangal & Ramagundam U/s at Karimnagar (3.5 mg/l) inAndhra Pradesh. The Faecal Coliform ranges from 1-500 MPN/100ml whereasthe Total Coliform ranges from 7-2400 MPN/100 ml.The River Godavari at most of locations in Maharashtra and Bhadrachalam U/s,near Rly Bdg B/c of Rallavagu at Mancherial, Rajahmundry D/s, Godavarikhani,Ramagundam U/s & D/s and Burgampahad in A.P. is exceeding desired waterquality criteria. The sources of pollution is from domestic and industrialwastewater generated from the large cities in Maharashtra and Mancherial,Ramagundam, Rajahmundry, Godavarikhani, Burgampahad and Bhadrachalamcities in Andhra Pradesh. Depletion of dissolved oxygen has been reported due toaddition of sewage into the river besides bacteriological pollution.
