Abstract
The present study deals with the Electrical Conductivity (EC) value of groundwater. Groundwater quality plays an important role in deciphering uses of water for drinking purpose. Due to poor quality of groundwater in the major parts of the district, people living in villages depend mainly on the canal water supply for drinking purpose. On the basis of EC the district has four groundwater quality zones. These are: fresh groundwater, marginal groundwater, saline groundwater and highly saline groundwater. The study is largely based on secondary data source. The base map of the study area has been prepared by using survey of India map. Data of EC values of groundwater of June 1988 and June 2014 was obtained from groundwater cell, Rohtak. Arc GIS 9.3 was used for preparing maps. Interpolation technique was used for preparing maps. Objective of the study is to access the groundwater quality based on Electrical Conductivity (EC) value. As per the analysis, the area falls under fresh water zone increased from 305.71 Sq. Kms. In June 1988 to 460.19 in June 2014. Area under Marginal fresh and marginal category has been also increased from 574.14 Sq. Kms. And 441.45 Sq. Kms in June 1988 to 673.3 Sq. Kms. and 452.99 Sq. Kms respectively in June 2014. Saline water has been decreased from 343.24 Sq. Kms in June 1988 to 132.14 Sq. Kms in June 2014.
