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...

The practice of river quality classification usually uses Water Quality Index (WQI) to evaluate the WQI values river. However, due huge data collection on pollution with uncertain water parameter values, need a different approach classify quality. One supervised algorithms known as K-Nearest Neighbors (KNN) seems give new for where each points are classified according k number or closest neighb...

Groundwater is regarded as the primary source of agricultural and drinking water in semi-arid arid regions. However, toxic substances released from sources such landfills, industries, insecticides, fertilizers previous year exhibited extreme levels groundwater contamination. As a result, it crucial to assess quality for activities, both its current use potential become reliable supply individua...

Abstract Groundwater is an important source for drinking water supply in hard rock terrain of Bundelkhand massif particularly District Mahoba, Uttar Pradesh, India. An attempt has been made this work to understand the suitability groundwater human consumption. The parameters like pH, electrical conductivity, total dissolved solids, alkalinity , hardness, calcium, magnesium, sodium, potassium, b...

Water quality index (WQI) is the primary method applied to characterize water in world. The current study employed statistical analysis and multilayer perceptron (MLP) approaches for predicting groundwater Ghiss-Nekkor aquifer, northeast of Al Hoceima, Morocco. Fifty sampled were identified analyzed major anions cations throughout May 2019. Several physicochemical parameters all samples this in...

The aim of this study was to assess the potential impact of Trout farm effluents on water quality of Zaringol stream based on NSFWQI and WQI indexes. Some physicochemical water quality parameters were measured from 14 point during December 2009 to September 2010 seasonality. The average value of NSFWQI is 53.21 and it shows spatial and temporal variation. The maximum value or best water quality...

The concentrations of toxic effluents released into freshwater aquatic environments are increasing day by day and affect the aquatic biota. The present study outlined the evaluation of physicochemical parameters such as water temperature, pH, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), phosphates (PO42--P), nitrates (NO3--N), electrical conductivity (EC)...
