The main purpose of the research is the checking of some undesirable phenomena for the nature induced by the large scale heat storage method by means of the comparison 1) the change of the performance of the charge well, 2) activity of the microorganism in the aquifer, 3) ability of purification in aquifer between Finland in polar region and Japan in temperate zone.In Lappenranta, tap water has been supplied diretly by the groundwater recharge method since 1972. In Rajamaki, the groundwater has been used in cyclic by the method of artificial recharge as coolant of the distilllation from 1974. From 1985, artificial recharge method has been adopted as the pre-purification method for tap water. On the other hand, Solar Aquifer in Yamagata university has been running the experiments of seasonal heat storage from 1982.From the comparison the data obtained in the two countries, following results were obtained. 1. In Finland where they are proud of the long experiences more than 25 years, there have no problems occurred such as change of the water quality, increase of microorganisms and clogging of the charge well, originated by the aqifer thermal energy storage method.2. Purification performande in the artificial recharge pond increased due to the compound activities of iron bacteria and algae.3. Ferric colloid dam formed around the charge well increase the heat recovery factor, in additon to the work of the purification of the charge water.

通过对芬兰极地和日本温带地区的1）充水井性能的变化，2）含水层中微生物的活性，3）含水层净化能力的比较，来检验大规模蓄热法对自然界的一些不良现象。自1972年以来，自来水一直采用地下水直接补给法。在Rajamaki，自1974年以来，通过人工补给的方法循环使用地下水作为制冷剂。从1985年开始，采用人工回灌法作为自来水的预净化方法。另一方面，日本山形大学的太阳含水层从1982年开始进行了季节性储热实验。1.在芬兰，他们为超过25年的长期经验而感到自豪，没有发生水质变化，微生物增加和充电井堵塞等问题，起源于含水层热能储存方法。2.人工回灌池中铁细菌和藻类的复合活性提高了回灌池的净化性能.在炉料井周围形成铁胶体坝，提高了热回收率，并起到了净化炉料水的作用。
