The present work aims to assess the water quality index (WQI) of Manyad Storage tank, Aurangabad district, Maharashtra, India. surface sample were assessed for physico-chemical parameters namely pH, Electrical Conductivity, Total Dissolved Solid, Hardness, Bicarbonate, Chlorides, Sulphates, Nitrates, Calcium, Magnesium, Sodium, Potassium and Fluoride in post-monsoon season 2020. For calculating...

Various human activities have been the main causes of surface water pollution. The uneven distribution industrial enterprises in territories river basins Ukraine do not always allow real state quality to be assessed. This article has three purposes: (1) modification Ukrainian method for assessing WQI, taking into account level negative impact most dangerous chemical elements, (2) modeling WQI a...

Economic expansion coupled with population growth and associated anthropogenic activities are a threat to water resources globally. This study assessed the dynamics in quality trophic status of one South Africa's hyper-eutrophic reservoirs, Hartbeespoort Dam. Spatio-temporal variability parameters was determined on historical data spanning period forty years (1980-2020), aim determining decadal...

Aims of the Study: The physical, chemical and biological characteristics of Karaj River (near the city of Tehran, Iran), has been studied to evaluate the suitability of its water for domestic uses. Materials & Methods: Samples of water were collected from various localities before, in and after Karaj Dam Lake and were analyzed based on needs for Water Q...

For more than 25 years, the Department of Environment (DOE) Malaysia has implemented a water quality index (WQI) that uses six key parameters: dissolved oxygen (DO), biochemical demand (BOD), chemical (COD), pH, ammoniacal nitrogen (AN), and suspended solids (SS). Water analysis is an essential component resources management must be properly managed to prevent ecological damage from pollution e...

Background & objectives: Irrigation water quality is a critical aspect of agricultural production especially in terms of human health and the environmental aspects. The aim of this study was to estimate the level of surface runoff and groundwater pollution used in the production of agricultural products in the south of Tehran. Methods: Sampling points included 14 points of surface water collec...
