The Identified Problem	Causative Factors	Prevention Measures
Deterioration of lagoon/sea water quality	The effluent discharge from RO plants with increased temperature to the near by lagoon/sea will have sub lethal effects, such as whitening (bleaching) of corals, reduction of growth rate of corals and abundance of sea grass and benthic species.	A study on the impact of effluent discharge from desalination plants should be conducted and appropriate managements plants should be evolved prior to installation of any new desalination plants.
Air pollution	The predominant source of air pollution in the island is diesel generators for power production.	To control the increasing emission due to increased power generation and to regulate the long term effects of gaseous emissions, all the diesel generators may be provided with wet air scrubber. The waste water from the scrubber should be then subjected to sedimentation and filtration before recycling/discharge.
Intusive and annoying noise levels	The main source of increased noise level is the diesel generator based power plants. The indicative values show that the noise levels during day and night times is above the permissible limit for residential area.	In order to bring down the noise levels to the permissible limit, each individual generator may be provided with compatible modular type acoustic chambers orthe whole generator may be provided with acoustic plaster. Constructing a compound wall with 3m heights at 10m distance surrounding the generator house can ensure further attenuation of noise.
Pollution of lagoon water due to spilled oil	This is due to spillage of fuel oil during transportation at places like, loading and unloading locations, jetty, powerhouse etc. and supply in damaged leaky barrels. The traces of oil and grease are noted in lagoon water near the handling locations.	The oil pollution should be contained with better fuel handling techniques such as construction of better storage facility at the off loading area.
Stress on aquatic system	The presence, accumulation and increasing concentration of oil and grease will have effects on the coral reproduction, growth rate, photosynthesis, cell structure, colonizations capacities, feeding and behavioral. The discharge of soak pit effluent and disposal of coconut piths will add to the nutrient enrichment process in the lagoon waters, leading to eutrophication. This enhances the algal bloom, which will compete with corals resulting in coral mortality. Indiscriminate sport fishing, collection of ornamental fishes, lobster etc, scuba diving, reef walking, and unrestricted movement of motorized boats will all contribute to the destructing to the destruction of the corals.	Monitoring of the accumulation of hydrocarbon residues in the lagoon and reef area should be carried out regular interval so as to take appropriate measures if the pollution level exeeds the resilience limit. Sport fishing is and integral part of any island tourism and hence, it may be permitted in the lagoon and restricted on the coral reef.
Damage to corals	Careless boating habits and boating anchoring uproot corals. the siltation and subsequent to eutrophication would compete with corals, resulting in coral mortality. plastic containers and carry bags thrown in the lagoon would smother living corals and subsequently cause coral mortality	The problem of coral destruction due to boat anchoring could be alleviated to a large extend be deploying a series of mooring buoy system depending on the requirement. The wastes generated should not be dumped in the lagoon. Tt should be stored and disposed off in the seas, far off from the reef area, subjected to regulations of waste dumping in the seas.
