Abstract
The city of Kumamoto and its surrounding areas have a population of more than 0.7 million, and unique in that the prefecture-governed city boasts a water supply that is exclusively supported by an abundant groundwater system. The recent expansion of urban land-use areas in and around the city has resulted in a decrease in the volume of regional groundwater resources. This is despite the efforts of local governments to maintain stable groundwater recharge rates and the economical use of water. In addition, groundwater contamination, caused primarily by agriculturally derived nitrate, is increasing. Public education is necessary to maintain environmentally stable regional groundwater resources in terms of both quantity and quality. This paper describes the ongoing program conducted by the city of Kumamoto for this purpose.
