W celu wyodrębnienia glównych procesów wplywających na sklad chemiczny wody przeprowadzono wielowymiarową analizę statystyczną obejmującą analizę czynnikową i hierarchiczną analizę skupień 45 próbek wód gruntowych pobranych w dystrykcie Dhaka. Glówne skladniki uzyskane w wyniku analizy czynnikowej wskazują, że parametry odpowiedzialne za zmiany jakości wód gruntowych są związane glównie ze źródlami naturalnymi i antropogenicznymi, takimi jak odcieki z skladowisk odpadów przemyslowych, wycieki ścieków z osadów ludzkich lub stosowanie nawozów organicznych. Za pomocą hierarchicznej analizy skupień próbki wody zostaly podzielone na 3 grupy o podobnych wlaściwościach jakościowych. Analizę przestrzenną i interpolację wszystkich pierwiastków przeprowadzono za pomocą prostej metody krigingu, uzyskując rozklad glównych skladników (Na, Ca, Mg, Si i SO4), skladników drugorzędnych (K, Fe, Sr i B) oraz skladników śladowych (Mn, Zn, Li, Ba i P) w wodach gruntowych. Badania geologii podpowierzchniowej wykazaly, że glównym źródlem wód gruntowych jest warstwa wodonośna Dupi Tila pod Dhaka. Praca ta ma slużyc jako punkt odniesienia dla skutecznych dzialań w zakresie zarządzania zanieczyszczeniem wód gruntowych.
