Abstract
People in the southwest coastal region of Bangladesh suffer from a severe potable water crises due to saltwater at shallow depth (<200 m). Fresh water is present at depth >200 m. There is still a lack of exact causes, origin, and processes controlling the hydrogeochemistry of groundwater in the study area. Several aquifers such as the upper shallow aquifer (<100 m) is characterized by mostly brackish saline NaCl type of water due to infiltration of dissolved evaporite salts, not laterally from the Bay of Bengal. These salt-waters infiltrate into the brackish lower shallow aquifer (100-200 m). The deep aquifer (DA) below 200 m depth, is dominated by fresh NaHCO3+ type of water suggesting freshening conditions. The NaHCO3+ facies originated by cation exchange. The freshwater-saltwater interface varies in depth between 190 to 285 m. The shallowest depth is due to upward migration of fresh groundwater from the DA. Numerical modelling revealed that no fundamental changes in flow direction occur with a diffuse abstraction rate of 10.24 l/person/day from DA. This integrated study has helped to understand the characteristics and hydrogeochemical processes of the complex aquifer systems as well as to make sustainable use of water resources, especially from the DA.
