The following data may be a bit old--
the data may be presented using histograms.Sabarmati : 4 mg/L or BOD
BOD : biochemical oxygen demand.In 2010 the statistics are:Markanda: 590 mg Oxygen /liter BOD
Amlakhadi : 353Kali: 364Yamuna canal: 247 BOD
Yamuna near Delhi: 70 Betwa: 58 The above are the worst affected. Near cities and major towns the rivers are badly affected. In rural areas they are better.
BOD levels of 8 mg/L or less is acceptable... below 2 mg/L is good water. Ganga : at Rishikesh 1.5 mg Oxygen/L. at kanpur : 5 mg/L
Brahmaputra: At gauhati - very high. at other locations : 2mg /L or lessTapi : 2 mg/L in someareas. in cities and towns, about 13 mg/L BOD
Narmada : less than 2.5 mg/L BOD
Mahanadi : less than 1 mg O / Litre to 4 in cities or chattisgarh
Krishna: 1 to 3 in many areas... 10 in many cities/towns.... Around Pune: 28 mg/L
Cauvery : generally from 1 mg/L to 3 mg/L
Ganga : 4 - 8 mg / liter BOD
Godavari : 5 BODVitharini (Bitarni) : 2mg/l
Narmada : 2 mg/lMahi : 2.5 mg//l
