Surveys for Evaluating the Nogawa River Spring Water Corridor and Conserving Groundwater
(at that time)
|Study group for Water Path|
Spring water must be conserved and regenerated in order to maintain the water level in the spring-fed Nogawa River. While all possible means must still be employed to conserve the spring water of the Nogawa River, the spring water surveys that used to be carried out throughout the Nogawa River basin have ceased. Surveys by Tokyo Metropolitan Government and local municipalities are not adequate and do not grasp the extent of the problem. The survey by citizens first carried out 40 years ago was continued for 10 years. With the aim of re-evaluating and reviving this survey, we used this grant to conduct surveys of water levels, water quality, surrounding plants, and aquatic organisms at points where springs in the Nogawa River basin surface. We conducted these surveys during spring, which is the dry season, and during autumn, which is the wet season. We summarized the results in the form of a corridor map for distribution to relevant local governments and civic groups, with a view to sharing information and using it as material for further development of these activities in the future.
