This study evaluates the chemical properties of Shitalakshya River water bodies based on its chemical parameters such as Total Suspended Solids (TSS), pH, Electic Conductivity (EC), Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Nitrogen (N), Chlorine (Cl), Total Phosphorous (P), Sulfur (S), Potassium (K). To do this chemical analysis, pre-monsoon and postmonsoon seasons were considered to collect the samples from this river. This analysis shows that Total dissolved solids (TSS) of this river in both seasons have crossed the standard limit announced by WHO. The pH is less enough in the pre-monsoon season and in post monsoon it is up to the standard value. EC and Phosphorous both have crossed the standard value of drinking water in the Shitalakshya River. Nitrogen is too much less although it is a vital element. TDS, DO, BOD, COD, Cl, and S are approximately under the range of standard limits. The parameters that are high should be reduced in a proper treatment method so that this water can be used both for agricultural and drinking purposes.
