“…Disamping itu, permasalahan dipicu pula oleh perubahan pola aliran airtanah yang semula merupakan daerah resapan berubah menjadi daerah lepasan, sehingga terjadi penurunan muka airtanah dan perubahan tekanan hidrostatis. Hal itu kemudian dapat mengakibatkan terjadinya intrusi air laut ke airtanah (Lubis et al, 2006;Onodera et al, 2009;Marfai, 2007;Delinom et al, 2008). Salah satu faktor lingkungan yang menyebabkan perubahan kualitas airtanah adalah pengaruh air permukan masuk ke badan airtanah (Sudaryanto et al, 2014).…”

In the Bandung basin, Indonesia, excessive groundwater pumping caused by rapid increases in industrialization and population growth has caused subsurface environmental problems, such as excessive groundwater drawdown and land subsidence. In this study, multiple hydrogeochemical techniques and numerical modeling have been applied to evaluate the recharge processes and groundwater age (rejuvenation). Although all the groundwater in the Bandung basin is recharged at the same elevation at the periphery of the basin, the water type and residence time of the shallow and deep groundwater could be clearly differentiated. However, there was significant groundwater drawdown in all the depression areas and there is evidence of groundwater mixing between the shallow and deep groundwater. The groundwater mixing was traced from the high dichlorodifluoromethane (CFC-12) concentrations in some deep groundwater samples and by estimating the rejuvenation ratio (R) in some representative observation wells. The magnitude of CFC-12 concentration, as an indicator of young groundwater, showed a good correlation with R, determined using 14 C activity in samples taken between 2008 and 2012. These correlations were confirmed with the estimation of vertical downward flux from shallower to deeper aquifers using numerical modeling. Furthermore, the change in vertical flux is affected by the change in groundwater pumping. Since the 1970s, the vertical flux increased significantly and reached approximately 15% of the total pumping amount during the 2000s, as it compensated the groundwater pumping. This study clearly revealed the processes of groundwater impact caused by excessive groundwater pumping using a combination of hydrogeochemical methods and modeling.
