Abstract
Hooghly is one of the most important rivers of West Bengal, and it is also the centre for industrial development of West Bengal. Due to increasing industrialization and urbanization on Hooghly bank, its pollution level has shown an exponential growth especially in the region of Hooghly estuary. Its pH ranged from 7.9 to 8.4, phosphate showing lower concentration in monsoon and higher in summer. In Hooghly River, production of dissolved inorganic carbon (DIC) is 2.76 × 106 t/yr.; dissolve inorganic nitrogen (DIN) is 65.8 × 103 t/yr.; dissolve reactive phosphate (DRP) is 12.8 × 103 t/yr.; and silicate is 42.8 × 103 t/yr. Hooghly estuary considered as one of the most polluted estuaries in the world having half a billion litres of untreated waste from different industrial sectors dumped every year. This chapter highlights about the geomorphology and socio-economic importance of Hooghly River as well as change in pollution level from pre-Farakka period to recent times.
