| Abstract | On the southern slope of Mt. Merapi near the town of Yogyalrnrta, the volcanic products consist of lava flows, pyroclastics, lahars, and alluvial fan deposits, can be divided into old Merapi deposits, mature Merapi deposits, and young Merapi deposits. These deposits are andesitic to basaltic, and are composed mainly of plagioclase, olivine, pyroxene, hornblende, and biotite, with 50% to 55% of silica content. The mineral and chemical composition of Mt. Merapi products - as the source of the aquifers - control the geochemistry of groundwater transmitted through the deposits. Besides that, the quality of groundwater in this area is influenced and contaminated by man-made pollution. The contaminants detected in several groundwater samples of the study area are some heavy metals i.e. iron, lead, and mercury, arsenic, nitrate, and coliform. |
