Environmental Case Study of Water Quality of Ancient WellsMasabi Boudi and Narasimha Temple Well of Bijapur

Ancient historic wells or boudies, built by Adil Shahi kings in Bijapur are the huge sources of water in the drought place of northern Karnataka (India). They stand neglected and polluted. Masabi Boudi and Narasimha Temple well are two wells selected for the study. We have studied the water quality in terms of physico-chemical, biochemical, phytoplanktonic and bacteriological properties depthwise. Masabi Boudi exhibited a rare phenomenon of vertical inverse thermal stratification whereas in Narasimha Temple well winter thermal stratification broke in summer and monsoon. Phytoplankton occurrence was rare in Masabi Boudi. Desmids showed their pollution tolerance throughout the study in Masabi Boudi. Glucose, protein, creatinine, urea and uric acid in the water reads the utrophication, which resulted the growth of E-coli. Algal maximum was followed soon after the E-coli were in excess in both the wells. Chlorides, nitrates and nitrogenous content stated the rich nutritional status. The self purification of water takes place naturally as a quality control. There is a natural symmetry in the biological science between bacterioplankton and phytoplankton and high enrichment with organic matter provided a measure of stabilization to this eco-system. In all, Masabi Boudi shows better water quality than Narasimha Temple well.
