Limnochemical characteristics of Betwa river, Madhya Pradesh, India

Abstract

The  present  paper  deals with the monthly interval variation of limnochemical  characteristics  of  river  Betwa  during  October 2011 to August 2012. Five  major  sampling  station  (10 sites)  were  selected,  station- I Jhirri  (1 to 2 sites),  station- II  Nayapura  (3 to 4 sites),  station- III  Mandideep  (5 to 6 sites),  station- IV  Bhojpur (7 to 8 sites),  station- V Vidisha  (9 to 10 sites).  Various physico-chemical  parameters  like  temperature,  pH,    hardness,  Dissolved oxygen,  biological oxygen demand  and  chemical oxygen demand  were  measured, and  standard  methods  were  apply  in  the  present  work.  Studies  revealed  high values  of  hardness,  BOD and  COD  at  station  II  Nayapura  and  station  III mandideep, and  low  values  of  DO  and  pH  at  the  station,  where  station  I  Jhirri, IV Bhojpur,  and  Vidisha  low  values  of  hardness,  BOD  and  COD.  High  value of  hardness,  BOD  and  COD  indicate  the  river  water  polluted  at  station II Nayapura  and  station III  Mandideep.
