Hydrogeological Investigation of Six Asiab Regions in Wardak Province of Afghanistan

Ashok Vaseashta1*, Hafizullah Rasouli2 and Mohan Bahadur Chand3

Hydrogeological investigations are carried out in six Asiab regions in Chack, Wardak Province of Afghanistan. The Asiab region is located longitudinally to a valley that is parallel to the Wardak mountain range. In earlier times, the entire region was a big lake and as the water body receded along the width of these regions, this converted the entire region into one big fault at the Alishang Village. Currently, the Asiab River runs in a very steep area inside a valley causing erosion of the river all the way down to the riverbed. This river flowed from northeast to southeast and at the Alishang village; it changed direction from north to south and joined with the Gardan Masjid River. In these regions, all aquifer layers are located between the valleys and these formations are filled with gravel, sands, silts, loams, etc. and their accumulation along the river. Due to its accumulation on both sides of the river, the terraces (upper, middle and lower) consist of different types of conglomerates with different matrix materials which are found in different types of aquifers (aquifer, aquiclude and aquifuge). Since the residents use the water for general consumption, we tested water samples from 10 different wells in Alishang, Tapor, Kaday, Makhtoma, Kazian and Hakemkhel villages and assessed different parameters based on the different for- mations of stratigraphy according to their profiles. Due to regional conflict, the water quality and groundwater management have been ignored in this region, thus necessitating this research to provide necessary information to the local and state government for decision-making and management.
