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. Study on quantity and quality of water of the Lake can be done by way of Sipin analyzed the data using the method of precipitation F.J. Mock.

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.

Quality Indexes

Water quality indexes are a tool used to evaluate the physicochemical characteristics of a water body according to its use. The present study proposes the inclusion of oil and grease (OG) as a new water quality index (ICAMPFF-GA) parameter for the preservation of marine biota in tropical areas, since it is a typical pollutant found and measured in water bodies, causing damage to the aquatic environment. The normalized curve for OG was defined based on the percentage of surviving microorganism under a lethal concentration exposure of OG. The ICAMPFF-GA suitability was evaluated by its application to analyze marine water quality in the area of the sea outfall in the city of Cartagena, Colombia and comparing the trends of the outfall flow and the rainfall for 2017. Physical chemical data analyzed for the year 2017 shows that OG varies from 0.0 to 3.8 mg/L. The results show that the water quality index increases when rainfall and flow values increase for the rainy season. The ICAMPFF-GA can be a tool to evaluate the water quality of marine waters affected by the discharge of waters with oil and grease.

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.

Water quality is an important standard in matching water require and contribute. Abundant degree of freshwater is prominent for biological requirements and is a vital surface of incorporated environmental managing and sustainable development. The quality of water indices evaluation enterprise particular value which reduce the immense quantity of parameters and simply characterize data. The aim objective of the present study is to assess the suitability of surface water of Bounamoussa River situated in El-Tarf city located in the Algerian's extreme northeast, for drinking purpose based on calculated water quality index standards. Per methodology, WQI is a significant parameter to check the quality of water, and its calculation was carried out by using relations given in the water quality index computation which twelve selected parameters (pH, EC,TH, Ca, Mg, Na, K, Cl, NH4, SO4, NO2, NO3) have been considered, which were measured at nine stations along the river during two sampling campaigns (winter and summer seasons). The results showed that the computed WQI values of Bounamoussa River surface water extend from 32,80 to 65,77 with an average 46,76 in winter and fluctuate from 35,86 to 97,46 with an average of 47,25 in summer, in general, the study region in both seasons is under excellent to good category. Water from almost all the sampled sites can be careful as suitable for drinking purposes. It’s recommended to continue monitoring the water of this ecosystem to facilitate the establishment at all levels to supervise and defend the natural resources of the region.

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.

The Sukhna Lake of Chandigarh City is a man-made lake situated in the foothills of the Shivalik range in the north-east corner of the city. This urban lake is one of the prime tourist places of the ‘City Beautiful’ and is mainly used for recreational purposes like boating, morning and evening strolls, exercises, food plaza and sightseeing. The catchment of the lake is mainly hilly and erosion prone, with the Sukhna wildlife sanctuary comprising a major portion of it. The water quality index of the lake water and its dependence on catchment characteristics has been studied. By using the National Sanitation Foundation Water Quality Index (NSFWQI) and Overall Index of Pollution (OIP), the results of the water quality assessment have found the lake water as having ‘good’ and ‘acceptable’ quality respectively based on past seven years’ data. During the last few years, construction activities in the catchment area have speeded up and a few invasive alien plant species have come up in the lake. Inflow of untreated domestic waste water from nearby villages in the catchment, particularly during the rainy season, seems to be the main reason for the weed problem in the lake. Strict enforcement of ban on new construction activities and preventing the release of untreated domestic waste water from the villages located in the catchment are the absolute necessary steps for maintaining and improving the lake water quality.Hydro Nepal: Journal of Water, Energy and EnvironmentVol. 12, 2013, JanuaryPage: 26-31DOI: http://dx.doi.org/10.3126/hn.v12i0.9028Uploaded Date : 10/28/2013
