This study was conducted over seven villages near Darbandikhan district including (2) wells and (5) springs. It covers more than 60 km, to assess the suitability of ground water quality for drinking purpose using water quality index through investigating of different wells and springs; this technique is very useful tool for quick assessment for any water system. This was done by subjecting the ...

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 ...

the development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. as a result, an integrated multi-parameter water quality index has been developed. it is based ...
