14.2.2 Water Quality of tributary streams Indravati, Shankini, Manjeera, Maner,Wardha, Wainganga, Kolar, Kanhan, Purna, Nira, Kinnersani, Sabari,Bindusara, Darna, Penganga and WenaThe Water Quality of tributary streams Indravati, Shankini, Manjeera, Maner,Wardha, Wainganga, Kolar, Kanhan, Purna, Nira, Kinnersani, Sabari, Bindusara,Darna, Penganga and Wena indicates that BOD and DO are exceeding the criterialimit at certain locations whereas other parameters like pH, Conductivity andFaecal Coliform are meeting the desired water quality criteria. The DO rangesfrom 2.1-14.2 mg/l and the lower values of DO are found in River Maner atWarangal U/s (2.1 mg/l) in Andhra Pradesh and River Manjeera at D/s of Latur(2.7 mg/l); River Darna at Sansari –Nashik (3.0 mg/l); River Kanhan D/s ofNagpur & River Penganga at Mehkar- Buldana Road Bridge (3.1 mg/l); RiverWena at D/s of Mohata Mills (3.2 mg/l); River Wardha at U/s of Erai River (3.6mg/l), D/s of Erai River (3.7 mg/l) & D/s of ACC Ghuggus (3.8 mg/l) and RiverPurna at Dhupeshwar & River Wainganga at D/s of Ellora Paper Mills (3.9 mg/l)in Maharashtra.BOD ranges from 0.4-110 mg/l.
