The data include latitude and longitude of sampling locations ;physico-chemical parameters and factor scores .The data collection process involved the use of GPS (GPS, GARMAN 76CSx) to take both location and elevation data. Samples were collected from 50 different locations all of which are serving as sources of water for drinking, domestic usage in people’s homes and for irrigation usage. Each sample was collected in 500 ml acid-washed high density linear polyethylene bottle and clearly labeled. To remove particulate matter from samples, filtering was performed using a vacuum filtration kit and a 0.45-µm cellulose acetate filter membrane.The digital apparatuses were utilized to record pH, total dissolved solids and conductivity immediately after sampling onsite.Titration methods, flame photometry and Ultra-violet visible spectrometry were used to define the major ions; Na+, Ca2+, Mg2+, Cl-, K+, SO42+, PO4, Si(OH)4 and NO3-. Statistical analyses ,factor scores were used for understanding the dataset attained in the study area using Statistical Package of Social Studies (SPSS) version 15.0. The contour map of factor score was produced using Inverse Distance Weighted (IDW) raster interpolation and spatial analysis techniques built within ArcGIS® 9.3 software.
