Mumbai, Apr 26 (UNI) The coastal water quality is clean and healthy as per the American standard beyond five km in Mumbai from shore, according to a state-wise coastal water survey conducted recently.
The survey revealed the coastal water beyond two km is found to be clean except Mumbai where it is beyond five km from the shore, it may help people to consume seafood confidently, an official release here said.
In Thane Creek, the water quality survey revealed significantly reduced dissolved oxygen (DO) levels and increased Biochemical Oxygen Demand (BOD), ammonical nitrogen and faecal coliform levels in polluted stretches of the creek.
The data collected on the status of sources of land based marine pollutants under COMPAS programme revealed that the municipal sewage is the main single source of pollution to the coastal waters.
The water quality along the stretches of Veraval fishing harbour in Gujarat showed significantly reduced DO levels and increased faecal coliform levels. The data suggests that the organic loadings from fish processing industries and municipal sources are significant and have not been decreasing over the years.
In Gujarat and Maharashtra, there are 17 Common Effluent Treatment Plants (CETP) to treat the wastewater near the coastal areas to deal with the 2,392 small scale industries in Gujarat and 1,861 units in Maharashtra.
Most of the aqua farms are in the process of establishing effluent treatment system. In Veraval 42 fish processing industries have established a CETP of five MLD capacity to handle the wastewater generated by these industries which is being disposed into the harbour water, the release added.
