摘要：The seasonal monitoring of the water quality study of Loktak Lake has been undertaken to know the deteriorating water quality status. Twelve water quality parameters including Temperature, pH, Transperancy, Total Solids (TS), Dissolved Oxygen (DO), Biological Oxygen Demands (BOD), Acidity, Alkalinity, Chloride, Hardness, Turbidity and Nitrate were analysed. Temperature ranges from 16.8±0.98°C to 28.6±0.4°C, pH ranges from 6.3±0.2 to 7.4±0.05, Transparency ranges from 0.74 m to 1.7±0.03 m, Total Solids ranges from 23.3±5.77 mg/Lto 43.3±20.81 mg/L, Dissolved Oxygen ranges from 6.9±0.26 mg/L to 9.6±0.26 mg/L, Biologica Oxygen Demand ranges from 0.5±0.45 mg/L to 2±0.51 mg/L, Acidity ranges from 9.3±1.15 mg/L to 32.6±7.57 mg/L, Alkalinity ranges from21.3±1.15 mg/L to 73.3±1.15 mg/L, Chloride ranges from 20.9±2 mg/L to 42.3±1.52 mg/L, Total Hardness ranges from 18.7±3.05 mg/L to 68±4 mg/L, Turbidity ranges from Turbidity ranges from a maximum of 15.8±1.05 NTU in Site IV of summer season and a minimum of 0.4±0.05 NTU to 15.8±1.05 NTU and Nitrate ranges from 0.21±0.02 mg/L to 0.62±0.05 mg/L. pH and the Turbidity were not under the permissible limit range set by World Health Organization (WHO) and Bureau of Indian Standard (BIS-10500). The results refer to the polluted water status of the lake due to increasing discharge of waste and higher agricultural activities in the surrounding of the lake.
