Interaction of Precipitation and Groundwater Chemistry — Karnataka, India

Abstract—Precipitation obtained in the form of rain may contribute to surface and sub-surface sources. In this study precipitation and groundwater sampling was done and analyzed for chemical composition in urban, semi-urban and forest areas for the period 2009-2011. The scatter diagram of D v/s 18O of groundwater samples were drawn and compared with LMWL. The result indicating that the precipitation plays significant role in the groundwater recharge in the study region. The present study shows that lowest pH recorded was 6.82 at Bangalore North whereas highest 8.13 at Ramanagar. ANC found to be in Ramanagar (8.25 meq/100g), Bangalore north (2.71 meq/100g), indicating that it has inherent buffering capacity to neutralize the acidity of the precipitation. Soil CEC is in the order Bangalore north
Index Terms—ANC-acid neutralizing capacity, CEC-cation exchange capacity, isotopic composition, pH.
