Ammonium is a major constituent of many contaminated groundwaters. This study aims to understand the processes affecting ammonium loading to groundwater by analyzing water quality distribution and geological structure obtained from the long-term privately reserved data. The spatial distribution clearly showed the ammonium loading spot in terrace deposits area which having thick clay layers. Similarly, low ammonium concentration was distributed on the river deposit areas having thick clay layers. Therefore, to investigate the utility of privately reserved data of water quality, this poster will present temporal distributions of water quality data.
