Selection of the site for ATES is judged by measurement of the apparent thermal diffusivity of the aquifer. Development of the measuring method of the apparent thermal diffusivity is very significant. The unsteady measuring method given by UMEMIYA needed very long time about a day. In this report, the measuring method is developed to enable the measurement in short time less than 12 hours. Field experiments, the measurement of the apparent thermal diffusivity of the aquifer by the newly proposed method were carried out in 3 well, 2 of them in "Solar Aquifer" and the other one, newly dug at "KATAKO" in 1999 as snow melting system. The recovery factor in "KATAKO" was estimated as 15% at most judging with the operational dimensionless charge quantity obtained from the apparent thermal diffusivity. The recovery process has continued in this winter from December 1999 until March 2000.
