Zusammenfassung

Abstract Water quality of Titijhola area a tributary of Rani Durga River System was evaluated by water quality Index (WQI) technique. A quality of water index provides a single number that expresses overall water quality at a certain location and time based on several water quality parameters. The aim and objective of an Index is to find out the complex data of water quality into information having useable and understandable by the public. The most important parameters i.e PH, Suspended solid (SS), Total dissolved solids (TDS), Iron (Fe), Chloride (Cl), Sulphate (SO4), Nitrate (NO3), Biochemical Oxygen demand (BOD), Fluoride (F), Alkalinity for the year 2017, 2018 and 2019 were taken for the calculation of Index of water quality of Rani Durga River at Titijhola village ranged in Table-I. The WQI values indicate that the water was not pure at the sampling site except for 3 months having the values were very less. By human activities having Podu Chasa (Shifting cultivation) in the hill near river, water gets polluted and the index of water quality value decreases. It was observed that the parameter having least amount contributes a high statistical value of the index. The water qualities of different sources were used as a tool for comparison of index of water quality. In a particular region of Rani Durga river of Titijhola area is problems of drinking water. It is the effective ways on water quality trends to the public and water quality treatment and management. Key Words: Water quality Index (WQI), Rani Durga River, Water quality treatment and management (WQTM), Statistical value.
