Abstract
Precipitation obtained in the form of rain maycontribute to surface and sub-surface sources. In this studyprecipitation and groundwater sampling was done and analyzedfor chemical composition in urban, semi-urban and forest areasfor the period 2009-2011. The scatter diagram of D v/s 18O ofgroundwater samples were drawn and compared with LMWL.The result indicating that the precipitation plays significant rolein the groundwater recharge in the study region. The presentstudy shows that lowest pH recorded was 6.82 at BangaloreNorth whereas highest 8.13 at Ramanagar. ANC found to be inRamanagar (8.25 meq/100g), Bangalore north (2.71 meq/100g),indicating that it has inherent buffering capacity to neutralizethe acidity of the precipitation. Soil CEC is in the orderBangalore north<Bangalore south<Mandya<Ramanagar.Decreased CEC resulted by soil acidic processes. Precipitation isthe dominant source for the ions present in groundwater and innon-rainy season it is rock dominance.
Keywords
