Fighting against POLLUTION to Save Environment
CONCLUSIONS

  • The river water undergoes extreme fluctuations in the concentration of elements during various seasons.
  • The concentration of elements was higher at the spots like Kole, Khubi, Jackwell and Ganesh Temple where industrial wastes and sewage is discharged.
  • The river was not conducive to the growth of aquatic organisms of at most of the spots due to the presence of high / biogenic and industial pollutants.
  • There was substantial fecal pollution too in the water which should be unscrupulously disinfected before human consumPtion, especially at Sangli.
  • A detailed prolonged integrated study on the river is very much essential in the near future which should cover physico-chamical, biological and socio-economical aspects.
