Pollution impact assessment along Vasai Creek of Mumbai: measurement of physico–chemical parameters

0
The rapid urbanisation and industrialisation in Vasai City of Mumbai with improper environmental planning has resulted in discharge of sewage and industrial wastes in to the Vasai Creek thereby greatly affecting its physico–chemical properties. The present investigation to study the physico–chemical parameters of creek water for the two assessment years 2009 to 2010 and 2010 to 2011 suggests the high level of aquatic pollution. It is observed that pH; solid content, total hardness, sulphide, phosphate, phenol, and oil/grease content, as well as BOD/COD values were above the maximum permissible limit for set for inland surface water subjected to pollution load. The results also indicates that the pollution level of 2010 to 2011 were above that of 2009 to 2010. It is observed that the present high level of pollution will not only not only create threat to the aquatic life of the creek, but also affect the aesthetic beauty of the creek.
