ABSTRACT

 

Present work reports about the physico-chemical characteristics of groundwater collected from Udupi city, Karnataka, India. In order to evaluate the quality of groundwater in the study area, 35 open wells were selected from 35 wards of Udupi Municipal area and water samples from each open well were collected. Analysis is done for various parameters such as pH, Electrical Conductivity, Total Dissolved solids, Total Alkalinity, Total Hardness, Sodium, Ammonium, Potassium, Magnesium, Calcium, Fluoride, Chloride, Nitrate, Sulphate, Iron, Cobalt, Nickel, Cadmium, Lead, Chromium, Manganese and Copper. The obtained results were compared with the standards laid down by Bureau of Indian Standards (BIS). Geochemical nature of water was determined using Piper's diagram. Suitability of groundwater for drinking and irrigation purpose was interpreted. BIS drinking water quality standards were adopted for calculation of Water Quality Index (WQI) to find the suitability of water for drinking purpose. Inverse Distance Weighing (IDW) technique has been used to estimate the spatial distribution of Water Quality Index. Study reveals that about 22.86% of samples belong to good water quality. However 2.86% of samples belong to unsuitable for drinking category.
