Abstract

In the study area, the Pleistocene aquifer has small depth. From 2009, pH was discovered with high depletion and suddent increase of aluminum in groundwater. However, in 2013, the aluminum concentratin seems to be stable. The analyzed results of mineral composition, soil, sludge, groundwater, and waste water samples showed that sources of aluminum is mainly from the local soil material, and the other is from the industrial activities. Hydrolysis of alumosilicat is the main process that put aluminum into groundwater. Factors supports the dissolution of aluminum in groundwater are hydrogeological structure, soil materials, over groundwater pumping activities, irregular casing of wells, agriculture activites, etc.
