Impact Of Excessive Pumping On Groundwater Quality: The Arsenic Problem Of The Ganges–Meghna–Brahmaputra Delta In Southeast Asia, Rhitwik Chatterjee, Mousumi Chowdhury

Journal of Environmental Science and Sustainable Development

This review of the impact of large-scale pumping on arsenic distribution reveals that groundwater-fed irrigation and domestic withdrawal impart tremendous stress on the limited groundwater resource base and disrupts the dynamic equilibrium of the groundwater system of the Ganges–Meghna–Brahmaputra (GMB) delta in Southeast Asia. Excessive groundwater extraction through pumping affects the groundwater quality in three major ways. First, excessive pumping transports atmospheric oxygen and organic-rich surface water to the subsurface. Second, it promotes arsenic build up in surface soil irrigated with arsenic-laced groundwater. Finally, it shifts groundwater replenishment zones lying at various depths near extraction points, thus, carrying dissolved arsenic …

Assessment Of The Groundwater Recharge Potential Areas Using Gis In Kajor Kulon Hamlet, Selopamioro, Imogiri, Bantul, Yogyakarta, Deni Rahman Saputra, Andi Renata Ade Yudono, Partoyo Partoyo

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Groundwater balance occurs in the presence of recharge and discharge. The process of entering the water in soil takes place with an infiltration-percolation to aquifers. The groundwater recharge area is identified by lithology, land use, slope, rainfall, land, and landform. Kajor Kulon Hamlet, Selopamioro Village, Imogiri Sub-district, Bantul Regency, Special Region of Yogyakarta becomes an area with hilly morphology, active fault areas, and including drought-prone regions. Change of the land function in hilly areas by making settlements and un-irrigation field for farming may cause decreased ability as a recharge area. Research aim sare to assessing, determining, and analyzing the conditions …
