Kyushu University has been constructing its new campus (Ito Campus) in an area spanning the Motooka-Kuwabara district in Fukuoka City. Agriculture is active in this area and a large amount of groundwater is used for irrigation and horticultural facilities. In recent years, land development for house building has proceeded and one of groundwater recharge sources, paddy area has decreased. Therefore, it is the urgent need to grasp the total amount of groundwater discharge by pumping wells. It was estimated that dividing into three usage ways; for living, agriculture and business. The result shows the daily average groundwater discharge is approximately 635m3 and the percentages of groundwater usage are 59 percent for agriculture, 38 percent for living and 3 percent for business. Next, saline-affected groundwater by effects of groundwater pumping was evaluated from value changes of EC (electrical conductivity), Na and Cl at the wells for agriculture. Consequently, it was revealed that groundwater pumping has an effect on salinization of groundwater and its influences were reflected on the groundwater quality about one month later.
