Abstract Honghu Lake is the largest lake-type wetland in Hubei Province, China. It is also one of the largest shallow lakes in the Yangtze River Economic Zone, a key area in the relatively more developed southeast of China. However, the water quality has seen a deterioration tendency in recent decades, mostly owing to unreasonable human activities such as lake enclosure aquaculture following rapid social and economic development. Based on the water quality index (WQI) method, the water quality of Honghu Lake, by the vast amount of data collected from five observation sites monitored over ten years, was analyzed and evaluated. The results show that: (i) the water quality of Honghu Lake is in the ‘General’ grade as a whole with a WQI value of 43.41 ± 6.66; (ii) the water quality has been improving in the recent two years, reversing its decade-long deterioration; (iii) the water quality sampled at the Lantian site is the worst while that of the Guandun site is the best; (iv) the concentration of Pb and Cd are the key parameters to determine the water quality of Honghu Lake. Therefore, it can be concluded that more attention should be paid to investigate heavy metals in Honghu Lake in the future.

In this study Water Quality Index (WQI) was applied in Hemren Lake, Diyala province, Iraq using ten water quality parameters (pH, Electrical Conductivity, Hardness, Total Dissolve Soluble, Sodium, Calcium, Magnesium, Potassium, Chloride, Phosphate) from 2008 to 2010 to evaluate the suitability of Hemren Lake ecosystem for drinking and irrigation uses. The Weighted Arithmetic Index method (WAM) and the Canadian Council of Ministers of the Environment Water Quality Index methodology (The CWQI 1.0 model) were used to calculate the water quality index (W.Q.I). The results indicated that drinking water quality of Hemren Lake is good and marginal for the study period according to (WAM) and (CCME) respectively, while the irrigation water quality is good and according to (WAM) and (CCME). It is suggested that monitoring of the lake is necessary for proper management. Application of the WQI is also suggested as a very helpful tool that enables the public and decision makers to evaluate water quality of lakes in Iraq.

The Lake is an ecosystem of wetlands to note preserved. However, since the Lake is an open system that can also be utilized for the certain provisions tailored to support power and capacity of the Lake. One of the supported power and capacity of the Lake is the availability and quality of the water of the Lake. Sipin lakes located in the city of Jambi, have long been exploited by various parties, just that its utilization is not maximal for a variety of activities. To maximize its utility it is necessary to know the power support and power tampungnya. By knowing the power support and power tampungnya then it can be determined the allocation it is used so that will give you maximum results. One of the variables that need to be taken care of in order to use Sipin Lake against correspond to peruntukkannya is about the availability and quality of water.

In order to determine the water quality of Danube River, in the Galati area, the Water Quality Index was calculated. Water Quality Index is a useful number of overall qualities of water. Galati is a Danube port city located in south-eastern of Romania. Samples were taken from 9 places along the Danube starting with the place where the Siret flows into the Danube to the Profiland Steel Plant. Profiland Steel is a company in Galai whose main activities are: sheet and zinc strips; treatment and coating of metals. The monitoring period was one year, from November 2016 to December 2017. Every month, thirty physical - chemical parameters were investigated. In this study the assessment of surface water quality was determined on the basis of various indicators such as: potassium and calcium ions, nitrites, nitrates, total nitrogen, ammonium, chlorides, total phosphorus, sulphates, cadmium, chrome, copper, lead, iron, zinc, density, dissolved oxygen, chemical oxygen demand (CCO-Cr), biochemical oxygen demand (CBO5), electrical conductivity, the density of the conductivity, resistivity, pH, salinity, total dissolved solids. The water quality index (WQI) has been calculated by using Weighted Arithmetic Water Quality Index Method. Two types of correlations were developed: Pearson correlation matrix and Spearman correlation.

AbstractClean, safe and acceptable fresh water is fundamental to the existence of life. There is still a serious problem with adequate availability of fresh and quality of water for human consumption. This study, therefore, assesses the relevance of groundwater in the selected sites of villages of Palakonda mandal in the Srikakulam district of Andhra Pradesh, India, for consumption, based on different indices of water quality. Groundwater is the principal source for domestic and irrigation purposes in this region. In order to assess the quality of groundwater, 39 groundwater samples were collected during pre- and post-monsoon season from 2013 to 2016. The concentrations of physicochemical parameters such as pH, electrical conductivity, total dissolved solids, total hardness (TH), Ca(II), Mg(II), fluoride (F−), chloride (Cl−), dissolved oxygen, total alkalinity and nitrite (NO2−) were analyzed to compute Water Quality Index (WQI). The results of the concentrations were interpreted and compared with WHO (2012) and BIS (2012) standards. Correlation between various parameters was also computed, and the results were presented. The results of WQI computation infer that the groundwater of the selected sites in Palakonda mandal is rated as ‘good’ for human consumption.

This study is done to evaluate water quality of the Thamirabarani river, by using Water Quality Index method. The water quality index of the river water was done, by analyzing the physical and chemical parameters of water samples taken at seven locations in Jan 2017 to March 2017, along the through flow path of the river. The analysis results were compared with maximum permissible limit values recommended by WHO and BIS for drinking, irrigation and aquatic life. The water quality for Dinking was assessed utilizing the WQI technique. The computed WQI values in this study are found to be between 55.65 to 23.3(for drinking), 47.1 to 14.4 (for Irrigation) and 61.2 to 15.4(for Aquatic life).The results are indicates that, for the stretch of Tamirabarani where study was conducted, the water is suited for irrigation.

Rivers are considered the most important sources of surface water on Earth. They are play a significant role in all human activities and the quality of river water is needed. Therefore, the importance of the water quality index is arising through providing data base about quality of the water source, and explain the change in the water quality over a period of time continually. This study involved determination of physicochemical and biological parameters of Lower Zab river in Kirkuk city at two different points. The objectives of the study are to assess the present water quality, through analysis of some selected water quality parameters like pH, TDS, BOD, dissolved oxygen, turbidity, EC, alkalinity, and salinity etc. and to compare the results with the Canadian Council of Ministers of the Environment and National Sanitation Foundation Water Quality Indices. Raw water samples were collected from the Lower Zab river twice a month by one sample every 15 days from each station. The water quality data include 16 different parameters. Tests were carried out following the American Public Health Association standard methods. The results show that all parameters values were within the standards of drinking water proposed by the CCME standards and Iraqi standards or the World Health Organization standards for drinking purpose, except turbidity, DO, nitrate, calcium, which were mostly higher than the standards and sometimes BOD and potassium. The results of WQI showed that the water quality at LZ3 station is lower than LZ2 station due to the polluting activity of the Lower Zab river. Furthermore, for the years 2014, 2015, and 2016, the water quality was degraded due to the ISIS war. Also, it was noted in the 2013 year that the water quality degraded more in fall and winter seasons due to that the earth has exposed to the long-dried season and then suddenly exposed to a high rainfall season which in turns leads to increase some parameters very high (i.e. turbidity). Finally, the Lower Zab river water cannot be use for drinking directly. However, a pretreatment is needed before the drinking use.
