Impact of fabric dyeing effluents on the physical parameters of Wunna river in Ward ha district of Maharashtra

Abstract

The  physical  parameters like  temperature,   odor,  electrical  conductivity,  turbidity  and pH of Wunna River in Maharashtra  (India)  at three  different  stations  (upstream  region-  S,, effluent  mixed  region• S,  and  700  m  away  from  effluent  mixed  region-S,)  were  studied   during  the  pre,  mid  and  post• monsoon   season.   Marginal  variations  were  recorded in temperature and  turbidity while  rigorous effect  of effluent   discharge on odor,  electrical  conductivity and  pH was  observed   at the  effluent mixed  region  as compared  to the  other  stations.  The  flow of water  in  the river  in  different seasons was found  to be an  important factor  responsible for variable  impact of pollution.  The  data  analysis confirms  a great  extent   of pollution  of the  riverine eco-system  at  the  site  of release   of textile industry  effluents
