Abstract
Management of groundwater resource is determined by its accessibility and utility in terms of quantity and quality. The results of chemical analysis for pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), total alkalinity (TA), calcium (Ca+2), magnesium (Mg+2), sodium (Na+), potassium (K+), chloride (Cl-), nitrate (NO3 -), sulphate (SO4 -2) and fluoride (F-) of 18 water samples collected from Lalsot urban area in Dausa district are presented. Based on the results, certain parameters like sodium adsorption ratio (SAR) and percent sodium (% Na) were also calculated. Statistical analyses have been carried out using chemical data to classify geo-chemical evaluation of the aquifer system based on the ionic constituents. Salinity and nitrate contamination are the two major problems in the area, which is alarming considering the use of this water for drinking. The major factors influencing the water quality are local geo-chemical formation, water-rock interaction, flow direction of groundwater and rainfall that control the overall mineralization.
