In Wonchi district, there are eight wetlands, which include lake, marshes and swamps. These Wetlands play great role in providing holistic ecological services for the district, conserving and protecting plants and animal life. Recently, these wetlands are highly threaten with anthropogenic activities like overgrazing, cultivation, rim disturbance through infrastructure construction, deforestation, settlements in and near wetlands. However, there is no sufficient information that shows water quality status of wetlands. Hence, this study aimed to assess the water quality of the wetlands and their ecological implications. A total of 126 water samples were collected from eight wetlands from October2016 to May 2017. Water samples for physicochemical, microbial, biological and heavy metals analysis were collected using polyethylene bottles. The samples were analysed in the laboratory according to standard methods for water and wastewater analysis. Data Analysis was performed by descriptive statistics, one-way Analysis of Variance (ANOVA), and Multivariate analysis using SPSS IBM 20 and CANOCO for windows 4.5 version soft ware. The overall water quality parameters analysis results have been as ranged pH(6.7-8.6), E.C(123-1978) ,Temperature(7.9-29.3 ), Turbidity(0.5-1124 NTU), DO(2.7-12mg/l) BOD(0.1-5.04), COD (2.5-142),No3-N (0.02-11.9), No2-N (0.002-0.3), SRP(0.01-3.5mg/l), TN(2-54), F-(0.16-3.2), TP(0.05-3.9),TH(22-238), Chloride(14-84.3), TSS(0-4.5mg/l), Fe(0.01-4.6)T.F(0-1165), F.C(0-930). The water quality indices of the wetlands were computed and values ranged from 164 to 640. These results revealed the wetlands water quality status were not good for public health and drinking purpose. Nutrient loads and over utilization of the resources in the district were the most significant factors that may have led to the reduction of water quality problem. The result of this research can be used for different purposes including assessment of water quality in aquatic ecosystems for the ambient water quality targets in SDGs.rnKeywords : Wonchi district Wetlands, Physicochemical & Biological parameters, multivariate analysis, WQI
