“…Ganjiang River, the largest river in Poyang Lake basin, plays an important role in providing drinking water, irrigation and fishery services for the local residents [20]. The Ganjiang River basin feeds more than 20.2 million people, and the pollution of the basin has become increasingly prominent with the acceleration of industrialization and agriculturalization processes in the past decade [21,22]. Hu et al [23] found that mining activities and industrial activities caused severe heavy metal pollution in the river.…”

Heavy metal pollution is one of the important threats to river water quality and human health. Here, we collected surface water samples from the mainstream and tributaries in the Ganjiang River basin in January and July, 2015, in order to delineate the temporal-spatial distribution characteristics of heavy metals, identify their sources, and assess their potential risk. Compared with China's environmental quality standards for drinking water, our results revealed that 5 heavy metals, including Fe, Al, As, Mn and Tl, exceeded the standard values and the over-standard rates were 21.62%, 16.22%, 8.11%, 4.05% and 4.05%, respectively. The concentrations of hydrochemical ions and heavy metals exhibited significant seasonal variation and spatial heterogeneity. Multivariate statistical approaches indicated that intense anthropogenic activities (mining industries and agricultural activities) were the most important sources of heavy metals in the Ganjiang River, and the upstream of the Ganjiang (in southern Jiangxi Province) and the Yuan River were the regions with the most serious pollution. Assessming health risk using the hazard index (HI) and carcinogenic risk (CR) recommended by the USEPA showed that children were more susceptible to the health risk than adults, and As was the most largest contributor leading to noncarcinogenic and carcinogenic risk to human health. Therefore, effective measures such as controls on mining wastewater and the use of pesticides and fertilizers should be taken by local government to protect aquatic ecosystems and human health.

“…A method that allows the qualitative and quantitative representation of the surface water's quality is the Composite Water Quality Identification Index method (CWQII) explained in [2]. The differences when employing various methods were investigated by a large number of researchers [3,4,5]. In their research, Lumb et.…”

The surface water quality index is used to more clearly display the state of the considered water quality. There are many different methods used to attain this goal. Depending on the employed method there is a number of parameters that should be included in the analysis in order to provide reliable results. This also alows the user to represent the water quality with only one number using data from a couple of years. This paper investigates the influence of spatial differences of the water quality within the same surface water, relying on the CCME WQI methoid. The research is conducted using the available water quality data on Lake Ludas.

“…In order to present the quality of a surface water both qualitatively and quantitatively, the Composite Water Quality Identification Index method (CWQII) was developed [2]. Various authors have compared different methods in order to determine the difference in the attained results [3,4,5]. One of the widely used methods for the representation of the WQI is the Canadian Council of Ministers of the Environment Water Quality Index method, CCME WQI, [6,7,8].…”

A water quality index (WQI) is a way to represent complex water quality data and communicate it to the general public. This paper represents an overview of the CCME WQI method. The considered method incorporates three main elements, the number of variables not meeting water quality objectives (scope), the number of times these objectives are not met (frequency), and the amount by which the objectives are not met (amplitude). As a result, a number between 0, being the worst water quality, and 100 being the best water quality, is attained that is used to describe the surface water's state. After an in depth analysis, the method is applied for the determination of the CCME WQI of Lake Ludas for the year 2012.
