The construction work in coastal and marine zones has an impact of environmental quality degradation. It causes an environmental pollution which has brought changes in the physical, chemical and biological characteristics of the water environment. Temperature and pH as physical parameters can directly affect marine ecosystem conditions. This research aims to study the pH and temperature conditions and to simulate distributions of these components in Palopo seawater. Direct pH and temperature measurements are provided in eleven stations and implemented on December, 2017. Also, Geographic Information System (GIS) and Surfer 13 software are applied to analyze all obtained data. The results of pH and surface temperature measurements in the Palopo's coastal waters, it showed that surface pH values range from 6 to 6.5. This value is below the quality standards for sea water pH to marine biota around at pH7-8,5, while the surface temperature value is at around 31,5 - 33,3oC. This value has passed the sea water quality standard for marine biota at 28-30oC. A simulation mapping result indicates that the distribution of pH and surface temperature is affected by increased community activity in coastal waters.

Japan experienced serious water pollution during the period of high economic growth in 1960s. It was also the period that we had such damages to human health, fishery and living conditions due to red tide as much of chemicals, organic materials and the like flowing into the seas along the growing population and industries in the coastal areas. Notable in those days was the issues of environment conservation in the enclosed coastal seas where pollutants were prone to accumulate inside due to low level of water circulation, resulting in the issues including red tide and oxygen-deficient water mass. In responding to these issues, we implemented countermeasures like effluent control with the Water Pollution Control Law and improvement/expansion of sewage facilities. In the extensive enclosed coastal seas of Tokyo Bay, Ise Bay and the Seto Inland Sea, the three areas of high concentration of population, we implemented water quality total reduction in seven terms from 1979, reducing the total quantities of pollutant load of COD, TN and TP. Sea water quality hence has been on an improvement trend as a whole along the steady reduction of pollutants from the land. We however recognize that there are differences in improvement by sea area such as red tide and oxygen-deficient water mass continue to occur in some areas. Meanwhile, it has been pointed out that bio-diversity and bio-productivity should be secured through conservation/creation of tidal flats and seaweed beds in the view point of “Bountiful Sea” To work at these challenges, through the studies depending on the circumstances of the water environment in the enclosed coastal seas, we composed “The Policy of Desirable State of 8th TPLCS” in 2015. We have also added the sediment DO into the water quality standard related to the life-environmental items in view of the preservation of aquatic creatures in the enclosed water areas. Important from now on, along the Policy, is to proceed with necessary measures to improve water quality with good considerations of differences by area in the view point of “Beautiful and bountiful Sea”.
