Publication Date : 25/11/2020
The Candi Umbul hot spring is located at Kartoharjo Village, Grabag Sub district, Magelang Regency. There is an archeological site at the hot spring area, which is improving the place to be an interesting object. Unfortunately the hot spring temperature is quite low, 33oC-35oC, then it was encouraged us carry out the survey. We apply geochemical method and shallow ground water aquifer observation. Candi Umbul geothermal field consist of three geothermal hot springs, there are distributed as a line parallel with geologic structure. The hot springs are characterized as bicarbonate and mature water that shows the system is an outflow zone. According to shallow water aquifer data, overabundance of meteoric water causing the hot spring becoming cool.
