Estimation of seasonal variations in physicochemical and biological parameters of tapi river water in surat region. gujarat. india

Tapi River water sample has been analyzed for the parameter of pH, BOD, DO, Conductivity and Total Coliform Organisms. River water samples were seasonally collected at the location of Savjibhai Korat Bridge, Kapodra – Utran Bridge, Amroli Bridge, Dabholi- Jahngirpura Bridge and Weir- Cum- Causeway Bridge. Physico chemical test parameters such as pH, BOD and Conductivity observed in increasing order from location 1 to location 5. Tapi river water does not complies the BOD and Total coliform Organism test parameters, hence Tapi river water does not corresponds with the CPCB classification of river water Class A, B or C Category.
