Abstract:
Buriganga River is originated from Dhaleshweri and it is referred as one of the most polluted
rivers around Dhaka. On the last three decades significant numbers of textile and tannery
industries have been established on the banks of the river, apart from the industrial establishment
a substantial amount of domestic waste has been dumping into the river water which
dramatically contributed the pollution increase of the river water. To investigate the quality of
Buriganga river water we analyzed the status of 10 physio chemical parameters including pH
(potential hydrogen), EC (electrical conductivity), TDS (total dissolved solids), Do (dissolved
oxygen), alkalinity, acidity, total hardness, free carbon dioxide, magnesium hardness and
calcium hardness of Buriganga River, we collected 11 water samples from 11 different locations
of Buriganga River which we further analyzed in laboratory using different tools and methods
including pH meter, EC meter, TDS meter and titration method. Our result indicate that most of
the parameters we analyzed exceed the limited standard set by WHO (world health organization)
and DoE (department of environment) peoples republic of Bangladesh for healthy water. In
addition to that our result highlighted a strong correlation between some parameters, this
indicates that the parameters were corresponding to one another; we had found this correlation
using correlation and linear regression methods. Our research has shown the deteriorating
situation of Buriganga River and surrounding environment and suggested a strong
recommendation to the concerned authorities however a wide scale research are needed to be
conducted to further develop a realistic mechanism to cope the increasing pollution.
