Groundwater Pollution Source Identification and Finding Governing factors using Factor Analysis for Bidar City and its Industrial Area, Karnataka State, India
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 4
Abstract
In this study the seasonal variability of groundwater quality parameters in Bidar city and its industrial area are investigated. Three water samples each from 35 wards were collected and subjected for physicochemical analysis. Average of the three samples represents each ward data. Analysis was done for pre-monsoon and post-monsoon seasons of the years 2009, 2010 and 2011. Seventeen physico-chemical parameters viz., pH, total hardness, calcium, magnesium, chloride, nitrate, sulfate, total dissolved solids, iron, fluoride, sodium, potassium, alkalinity, manganese, zinc, dissolved oxygen and total solids were analyzed. Factor analysis is applied on the data set to investigate the origin of the water pollution sources. FA yielded five factors for each season (combined pre-monsoon and combined post-monsoon) with 0.762% and 0.741 % total variance respectively, in addition FA identifies anthropogenic factor (i.e., industrial, urban sewage and agricultural drainage) and natural factor (top soil mixture with water and percolation, weathering of ground strata) as latent pollution sources.
