This study is objected to identify the annual variation of shallow groundwater quality in the study area, Hwabong-Jangam, Iljuk-Meon, Kyunggi-Do. The previous study in 2002 shown a wide-spread contamination of shallow groundwater by nitrate mainly originated from wastes of livestock facilities. In the year 2003, groundwater quality of the area has worsened due to the agricultural activities including the application of organic fertilizer and agro-chemicals to improve soil quality. In addition, a leaking septic tank, identified in the previous study, is still expanding its influence on the nearby wells.
