A Correlation Modelling of Various Hydrochemical Parameters to Interpret the Groundwater Quality of Jaipur City, Rajasthan (India)

摘要

This study was made to assess the analysis of physico-chemical parameters of ground water of Jaipur city. The chemical composition of the water was analyzed during monsoon session (July-October 2008). The ground water samples were collected from 18 sampling stations with different depth such as hand pumps, bore wells and shallow open wells, surrounding the industrial locations. The sutiability of ground water for drinking purpose was predicted with the help of Hill-Piper trilinear diagram and similarly the suitability of ground water for irrigation purpose, was predicted with the help of USSL diagram. The pH, EC, TDS were also compared with permissible limits. The analysis of ground water samples show higher values of EC, TDS, nitrate, calcium and magnesium. While the values of pH, sodium, potassium, fluoride and sulfate are compared with WHO standards and found within permissible limits. The Hill-Piper trilinear diagram shows that the majority of ground water samples are calcium-magnesium-chloride-sulfate type. The US salinity diagram shows that most of samples fall in C3S1 quality with high salinity hazard and low sodium hazard. Chemical analysis of groundwater shows that mean concentration of cation (mg/1) is in order, Na~+>Ca~(2+)>Mg~(2+)>K~+while that of for anion, (mg/1) HCO_3~->C1->SO_4~(2-)->NO_3->F-.
