A computer-aided multivariate water quality index is developed based on partial least squares (PLS) regression. The index is termed as the partial least squares water quality index (PLS-WQI). Briefly, a training set was computationally generated based on the guideline of National Water Quality Standards for Malaysia (NWQS) to predict the water quality. The index is benchmarked with the well-est...

The present study aimed to calculate the water quality index (WQI) by the study of nine physico-chemical parameters on the basis of Weighted Arithmetic Index in order to assess the suitability of water for drinking purpose and other human uses in Ranebennur Taluka, Haveri District, Karnataka, India. WQI, a tool of rating water quality, is a valuable model to assess spatial and temporal changes ...

A Water Quality Index (WQI) is a useful statistical tool for simplifying, reporting and interpreting complex information obtained from any body of water. A simple number given by any WQI model explains the level of water contamination. The objective was to develop a WQI for the water of the Luis L. Leon dam located in the state of Chihuahua, Mexico. Monthly water samples were obtained in 2009; ...

A reservoir with ecological and economic importance and its major tributary, localized in east-central Mexico, were studied. The aim of this work was to know the physicochemical water characteristics of both water bodies and to contrast these by their different uses, and also estimate overall water quality using a Water Quality Index (WQI). Water samples from the reservoir and the tributary wer...

background: survey of pollution and evaluation of water quality in rivers with oregon water quality index (owqi) and gis are effective tools for management of the impact of environmental water resources. the information in calculating the wqi of moradbeik river allowed us to take our tests results and make a scientific conclusion about the quality of water. gis can be a powerful tool for develo...

Pollution levels have been increasing in water ecosystems worldwide. A water quality index (WQI) is an available tool to approximate the quality of water and facilitate the work of decision-makers by grouping and analyzing numerous parameters with a single numerical classification system. The objective of this study was to develop a WQI for a dam used for irrigation of about 5000 ha of agricult...

The aims of this study were to assess and analysis of drinking water quality of Chabahar villages in Sistan and Baluchistan province by water quality index (WQI) and to investigate the water stability in subjected area. The results illustrated that the average values of LSI, RSI, PSI, LS, and AI was 0.5 (±0.34), 6.76 (±0.6), 6.50 (±0.99), 2.71 (±1.59), and 12.63 (±0.34), respectively. The calcu...

conclusions according to the average of wqi index, quality of water was good in station number one, medium in station number two, and bad in the rest of stations. according to the wilcox index, qualities of water in third station were medium and in the rest were good. results by using wqi, the best water quality was reported in station number one with the scalar quantity of 71.11 (water with be...

Rivers are the main sources of water for agricultural purposes in Malaysia. The Seberang Perai Rice Irrigation Scheme in the state of Penang is one of the eight main rice growing areas in Malaysia. The scheme consists of five (5) sub-schemes and irrigation water for each sub-scheme are supplied from either the Muda river, Jarak river, Kulim river or the Kerian river with pumping or gravity inta...

The Ephemeroptera, Plecoptera and Trichoptera (EPT) community structure and the specific sensitivity of certain EPT genera were found to be influenced by water parameters in the rivers of Gunung Jerai Forest Reserve (GJFR) in the north of peninsular Malaysia. The scores of EPT taxa richness of >10 in all rivers indicated all rivers' habitats were non-impacted, having good water quality coincidi...
