Abstract
The present study can be concluded that the analysis of the physio chemical parameters of Iril River revealed that most of the values are within the permissible limit of water quality standards. Water quality is suitable as per Standards norm of BIS and CPCB based on the determined values of pH, EC, TDS, DO, BOD, Chloride, Total Hardness, Total Alkalinity and Sulphate was monitored during the period of January 2023 to May 2023. The value of water pH recorded between 7.4- 8.34, EC ranged between 179.6 ms/cm-254 ms/cm, TDS ranged between 90.2 mg/l-126.8 mg/l, dissolved oxygen between 6.0-7.7 mg/l, BOD between 3.0 mg/l-3.9 mg/l, chloride between 28.9 mg/l-36.9 mg/l, total hardness between 112mg/l-170 mg/l, total alkalinity between 115 mg/l-174 mg/l and sulphate between 14.4 mg/l-39.3 mg/l. Hence, these rivers and hold to provide uninterrupted supply of drinking water to Iril River of Manipur without any major treatment.
