Water is an important precious natural resources on the earth. It is used in irrigation, industries and domestic usage. In this study of water quality assessment of Gowrivakkam lake was carried out. Total of 8 samples was collected from different parts of the Gowrivakkam lake and analysis for various physicochemical parameter like as pH, Alkalinity, Hardness, Chloride, TDS, Fluoride, Ammonia, Phosphate and Nitrite. The analyzed parameter were compared with BIS standards. Quality of lake water in the study area was calculated. The WQI of this lake was found to be good. Therefore, the water can be used only after treatment.

The parameters such as temperature, PH, TSS, TDS, ammonia, phenol, cyanide, sulfide, oil and grease, chloride, DO, COD and BOD were taken to assess the water quality of Sirsiya river, central southern Nepal. Water samples were collected from upstream to downstream from the point receiving industrial effluent to Sirsiya river. It receives wastewater burden of more than 250 industries along Bara/Parsa industrial corridor. All the parameters except oil and grease were found within the generic standard. The study revealed that the physic-chemical characteristic of the river water was changing as a result of the discharge of untreated effluents from different industries. This may impact on water quality of Sirsiya river and also pose human health problems.

Fuzzy Hierarchy

Taihu Lake can be divided into several different lake regions such as bay area, center area, lakeshore area and etc. according to the hydrodynamic characteristics and the lake morphology. In the year of 2010, water quality were measured in 17 sampling points, consisting of 8 points in the Zhushan Lake bay, 3 points in the western lakeshore area, and 6 points in the center area. The fuzzy hierarchy comprehensive evaluation model was used to assess the water quality in different lake regions on the basis of the measured data. This method is a combination of fuzzy evaluation to determine membership degree and Analytic Hierarchy Process (AHP) to determine weight. AHP can be further reduced to these steps such as the goal defining, hierarchy establishing, judgment matrix building, hierarchy single ranking, hierarchy general ranking and uniformity inspecting. The results show that water quality of Zhushan Lake bay is in class Ⅴ except for some points in class Ⅳ. Water quality of center area is between class Ⅱand Ⅳ, and that of lakeshore area is in class Ⅴ. The water quality assessment on the different lake regions by this method can more practically reflect the water environmental status of Taihu Lake. This works contributed to the improvement of water quality assessment exactness and lake eutrophication controlling in the situation of the lake with large area.

The City

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
