Problems of Excessive Exploitation andUtilization of Hot Springs
Masayuki HAMADA+Abstract
Judging from the statistics on annual changes of hot spring utilization published by
the Ministry of the Environment, the total ﬂow volume of hot springs has been continuously on the increase as well as the number of the wells. The assumption that the increase of the pumping wells would automatically bring about the decrease of the average
ﬂow volume is erroneous. The peak of the average ﬂow volume was recorded in the ﬁscal
year of +333. The largest total ﬂow volume of non-power used wells was marked in thesame year. Although people has shared the fear that the number of power used wells
would a#ect the naturally spouting wells in the neighborhood and probably it turned toreality in some areas, the negative trend produced in these ten years. Defectiveness oflicensing procedure for pump installation and speculations of user’s side make pump displacement of the wells very frequently inappropriate.
Key words : naturally spouting wells, pump displacement, licensing procedure ,**2  !"#$ +3 %&'()*+,-./0 123456
