Abstract

Groundwater is an important natural resource for sustaining life. The present study mainly focuses on the assessment of hydrochemistry of groundwater at three piezometric head locations of bore wells in Padmanabham Mandal Visakhapatnam District by using Weighted Arithmetic Method of the Water Quality Index (WQI)along with Inverse Distance Weighting (IDW) in GIS to show the spatial distribution of water quality parameters. The groundwater sample datasets of post-monsoon from 2019to 2023and pre-monsoon from 2019 to 2023 were collected. Physio chemical parameters like cations and anions are analysed. WQI indices used are Sodium Adsorption Ratio (SAR), Residual Sodium Carbonate (RSC), Sodium Concentration (Na%), Kelly’s Ratio (KR), Magnesium Ratio (MR), and Permeability Index (PI). The results from the study shows that the high pH value in both seasons, EC values are in the range of 1137-2340 µs/cm in pre-monsoon season whereas in post-monsoon season is 1105-2500 µs/cm are classified as a permissible to doubtful class. The average value of the WQI’s in Ananthavaram (62.73), Ayinada (54.41) and Pandrangi as (69.58) are classified as a poor class in pre-monsoon where as in post-monsoon in Ananthavaram (43.04), Ayinada (47.99) are classified as good class, and in Pandrangi (92.35) classified as very poor class.
