- Study on the change of groundwater quality distribution in the right side of Katsura river
説明
Shallow groundwater on the right hand side of Katsura River in Kyoto was investigated 13 years ago. Approximately the same investigation was executed this time and the results were compared to the previous one. The results of comparison showed that the concentrations of chloride ion and anionic surfactant decreased and quality of shallow groundwater in this area was improved especially in terms of pollution caused by infiltration of municipal waste water. The reason of this phenomena seemed to have a direct relation to the rise of percentageof sewered area. However, the area where the concentration of dissolved oxygen was low and that of Mn was high were not shrunk. This means that groundwater deterioration caused by the recharge of low DO water on the right side of Katsura river was not improved. The improvement of the quantity of shallow groundwater was also observed at a continuous monitoring point of Ministry of Land Infrastructure and Transport in this area. Sewerage infrastructure is thought to be effective not only for surface water but also for shallow subsurface water. The improvement of the quality of the recharge source of groundwater is also thought to be important for the improvement of groundwater quality.
