This study evaluates the chemical properties of Shitalakhya River water bodies based on its chemical parameters such as Total Suspended Solids (TSS), pH, Electric 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), and Potassium (K). To do this chemical analysis, pre-monsoon and post-monsoon 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 Shitalakhya 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. This assessment could be helpful for using it under agro-ecological planning. This water quality measurement leads whether or not it could use it for agricultural and household purposes. 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.
