| Water Pollution |
There is no water based industry in the A & N Islands. The water pollution level is very much below the limits. Port Blair is the only thickly populated town in these islands. The Municipal Council is responsible to maintain cleanliness in the town. In absence of a sewerage system in the town, the sewage goes to sea through the drains and gutters. Development of a sewerage system for Port Blair Town is under active consideration. |
| Hazardous substances Management |
In A & N Islands no industrial unit producing hazardous substances exist. However, there are three plywood industries which use hazardous chemicals. Regular inspections by the local Pollution Control Committee are carried out. All of them have prepared the Emergency Plan and Safety Report as stipulated in the Hazardous Wastes (Management and Handling) Rules, 1989. |
| Costal Erosion |
Over the years the destructive on sequences
of sand mining for construction is readily visible in the disappearance of several beaches, with its effects on wildlife on that region, as well as steadily increasing Coastal erosion that even newly installed sea walls are not sufficient to control. Coastal erosion islands are South Andaman, Peel, North, Bartang islands. |
| Water Pollution/Sedimentation |
Sedimentation appears to be the major cause for the decline of most coral reefs which is also associated with large-scale mortality in reefs, reduced coral growth, reduced fertility, and increased mortality of coral planulae and abnormal changes in polyp behaviour (Rogers, 1990). It is also important to establish the extent to which marine protected areas like MGNP are being damaged by murky or polluted water coming from upstream in South Andamans.
A pointer towards the shape of things to come is the observation that mud deposits have been found on the reef area at few places near Port Blair, Navy Bay, Flat Bay, Reef Island, etc. Sedimentation in the recent past in the AN I and elsewhere triggered off infestation of the crown-of-thorns starfish Acanthaster planci which has the potential to destroy whole reefs in a short period (Wood, 1989). Adding to further reefs problem is disease and bleaching imputed to rising turbidity. Protracted bleaching brings down growth rates and could be fatal. Corals particularly the branching types are prone to breakage, especially in the areas open to tourist or fisherfolks and others. Over-collection for construction or for sale as curios and ornamental and edible shellfish is proving to be a bane for the corals. |
