The current study was conducted to assess the water quality of Valley Duhok as a source for drinking livestock and poultry in region. Seventy-two samples were collected from six sites valley conduct physicochemical biological tests, sub-index model (WQI) applied quality.The results index indicated that Dam Lake (site N1) good poultry, while rest on category very poor animals, with WQI values ra...

This article aims to analyze the contamination of water and bottom sediment at Arroio Moinho (Mill Stream), in Porto Alegre (Rio Grande do Sul, Brazil). From two sample collections, a series diagnostic measurements were carried out, such as: a) physical-chemical biological analysis water; b) quality index (WQI); c) metal contamination, granulometric mineralogical analyses sediment; d) total org...

Recent techniques in the management of surface river water have been expanding the demand on the method that can provide more representative of multivariate data set. A proper technique of the architecture of artificial neural network (ANN) model and multiple linear regression (MLR) provides an advance tool for surface water modeling and forecasting. The development of receptor model was applie...

A study of the quality drinking water sources - surface waters river systems city Latacunga and canton Pedro Vicente Maldonado, Ecuador, was carried out during 2018 2019. The general sanitary index (WQI) calculated according to Russian methods, National Sanitation Foundation (NSF-WQI) Ecuadorian regulation. Results from parameterizing quality, obtained by WQI NSF-WQI methods combined into an ov...

Abstract The study aims to improve the quality of wastewater in Sulaymaniyah city, Iraq, which has been facing drought problems, by using sedimentation, dilution (1:1), and biochar filtration. It provides an alternative source water for agriculture, addressing shortage problem region. irrigation is evaluated based on Water Quality Index (WQI) a fuzzy inference system, mathematical tool that con...

Abstract Accurate assessment of the type and extent water pollution is a difficult complicated task. Therefore, use Water Quality Index (WQI) proves to be useful tool, as this index has advantage resulting in single number that easy communicate understand. One statistical methods can used develop new WQI equation for given body Multiple Linear Regression (MLR). work aims Mirim Lagoon through ML...
