Eleven physico chemical parameters of wetlands in West Garo Hill, Meghalaya were recorded in different seasons for two years to assess the quality status of water. The parameters were water temperature, pH, electrical conductivity (EC), dissolved oxygen(DO), biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solid (TSS), total dissolved solid (TDS), total hardness, nitrate(NO) and phosphate (PO4 ). The wetlands of west Garo Hill were found to be highly fluctuates with season. The wetlands did not showed significant difference between the two years. The water showed slightly alkalinity. DO was found normal as prescribed by WHO. COD and TSS were found beyond the permissible limit. The BOD was slightly higher than permissible limit indicates that though the water of wetlands are not polluted at present but it is going to be polluted. Pesticides, chemical fertilizers did not showed affect on water quality.
