Won the project threaten the natural ecosystem, coastal fisheries and local economy in Klong Daan?
17. No. Quite the opposite. Overall, the Project will have a beneficial impact on the ecosystem of the province, particularly on the canals and the coastal waters of Samut Prakarn. However, it is recognized that in the vicinity of the outfall (point of discharge) there will be a mixing zone in which “freshwater” from the treatment plant will disperse and assimilate into the surrounding seawater. The mixing zone may not be suitable for mussel farming. An exclusion zone will be established therefore around the area of the outfall. Significant reduction in total pollutant and nutrient loads is expected in the northeast corner of the Upper Gulf of Thailand. Some 72,000 tons/year of pollutants will be removed from waters entering the sea, thus providing substantial ecosystem benefits due to regional improvements to marine water quality. High levels of mercury and copper are also being found in sediment off the Klong Daan coast, and the Government is studying how the project will improve the
