Groundwater quality for drinking purpose in Pennagaram block, Dharmapuri district, Tamilnadu, India

Abstract

Groundwater is an essential source of water due to its substantial use of domestic, irrigation and industrial purpose. The present study was pointed to examine the groundwater quality of groundwater in pre-monsoon and post-monsoon seasons on the year of 2013 at Pennagaram block of Dharmapuri district, Tamilnadu. A few groundwater samples of the study area were analyzed for their physico-chemical parameters (APHA, 1998). The spatial distribution map provides a clear explanation for hydrochemical characteristics of groundwater quality for domestic and irrigational purpose in both the seasons. The results of showed the most of the groundwater samples in the study area showed that the pH is slightly acidic to alkaline in nature. The TDS and EC content of the samples in PRM and POM were measured and found 80% of the samples within the WHO limit (1500 mg/L). The water constituents are highly adjustable with respect to cationic and anionic constituents. However, to summarize the average of cations is Ca2+ ˃ Na+ ˃ Mg2+ ˃ K+ and anions are Cl-> HCO3 > SO4 > NO3 > F. The spatial analysis output indicates that in some stations there is need for some degree of treatment for groundwater in the study area before consumption.
