We surveyed and selectively sampled the major water sources in Bamyan city surrounding area to assess quality. Water quality measurements were taken situ more samples collected for laboratory analysis from canals, rivers, springs, wells, supply systems. In urban areas, systems provide 36% of drinking water, but rural this source accounts only 7% supplies. Wells comprise 33% 15% supplies, respec...

Fifty sampling stations have been identified and water samples were collected from June to May 2008, to know the groundwater quality of Greater Visakhapatnam city using Water Quality Index. The samples were analyzed for the physico-chemical parameters like Temperature, pH, Conductivity, Total dissolved solids, Dissolved Oxygen, Hardness, Calcium, Magnesium, Alkalinity, Chloride and Nitrate. The...

In this investigation, an innovative index was developed based on the fuzzy inference system for assessing quality of bottled drinking waters. A method to aggregate values obtained from defuzzification step. total number 24 parameters revealing characteristics were in terms physiochemical, dietary, toxic, and pathogenic aspects selected as input parameters. 30 samples taken independent brands f...

evaluation of surface water quality is a complex process undertakingmultiple parameters. converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.the main aim of this study is to plan effective water resources management system forkarun river by combination of ccmewqi and geographic information system ...

Given the complexity of water quality data sets, resources pose a significant problem for global public order in terms protection and management. In this study, surface drinking irrigation purposes was evaluated by calculating Water Quality Index (WQI) Irrigation (IWQI) based on nine hydrochemical parameters. The discriminant analysis (DA) method used to identify variables that are most respons...

A large number of parameters are acquired during practical water quality monitoring. If all the parameters are used in water quality assessment, the computational complexity will definitely increase. In order to reduce the input space dimensions, a fuzzy rough set was introduced to perform attribute reduction. Then, an attribute recognition theoretical model and entropy method were combined to ...

Water has an important role in creating pollution problems in the mining regimes influencing the surrounding surface environment. The purpose of this study is to make an assessment of groundwater quality in an underground mine site in Portugal with a view of determining the pollution potential of groundwater. In the corresponding surface area of this underground mine, intersec...
