Water quality studies using remote sensing & gis technology in vaippar river, Tamil nadu

Hydro geochemical studies are of great importance in hydro geological investigation of ground water. Ground water samples from several wells in parts of Virthnagar District have been collected and chemically analyzed. The suitability of ground water for domestic industrial and irrigation demands have been discussed in this paper in terms of Handa’s classification, chloroalkalinity indices, potential soil salinity, permeability index, sodium adsorption rations, PH, EC, TDS, Major Iron concentration and by the mechanism controlling the ground water chemistry. The data were used to complete chemical parameters as no-corbonate hardness, sodium absorportion ratio, percentage of sodium residual sodium carbonate, magnesium ratio, corrosivity ratio, choro alkaline indices and permeability index found to be based on evaluation of the chemical parameters quality of water is fit for drinking, industrial and agricultural users, except in a few isolated locations. According to Gibb’s diagram most of the samples falls under rock dominance. Wilcox’s diagram indicates that less than 60 percent of samples fall in excellent to good and good to permissible types. According to the USSL classification of water quality of the samples belong to CS-S1,C5-S2,C5-S3 and C5-S4 classes water are also found in the area are which not suitable for irrigation.
