摘要：Calcium is a moderately soft, low melting reactive metal. It occures in its various forms viz chalk or marble (CaCO3), gypsum (CaSO4.2H2O ), anhydride (CaSO4), fluorspar (CaF2), appetite (CF2.Ca3PO4) 3, phosphorite (Ca3PO4), floropatite (3Ca3PO4.CaF2), etc. On reaction of the above substance, the water gets different types of species i.e. scale, corrosive and saturation. Calcium carbonate(CaCO3) saturation indices (Langlier index) is commonly used to find out the above species of calcium. In the present study, 03 samples were collected in each month from the selected stations of the river Mandakini viz. Satianusuiya, Spatikshila and Jankikund. The water samples of the above stations were taken during April, 2008 to March, 2009. Analysis was carried out using the standard methods for examination of water and wastewater (APHA-AWWA). The results of above analysis were fitted in Langlier Index in order to determine calcium speciation. Scale tendency was found to dominate in most of the sampling stations in all months of the study period.
