Water is an essential aspect of life and important in evolution. Recently the potable water quality topic has received much attention. The study aims to determine drinking Al-Najaf City by collecting samples throughout city comparing results with Iraqi guidelines (IQS 417) World Health Organization (WHO) guidelines, as well calculate WQI. Samples were tested laboratory between December 2021 Jun...
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...
For effective management of water quantity and quality, it is absolutely essential to estimate the pollution level existing surface water. This case study aims evaluate performance twelve machine learning (ML) models, including five boosting-based algorithms (adaptive boosting, gradient histogram-based light extreme boosting), three decision tree-based (decision tree, extra trees, random forest...
Wetlands in Lesotho are at the headwaters of some shared river basins like Orange-Senqu River basin. These wetlands threatened by various anthropogenic activities which compromising their water quality. This study assessed quality status Khubelu wetland and stream using parameters to determine its suitability for domestic use, irrigation, livestock watering. was a preliminary research on uses a...
Abstract The water quality index (WQI) model is a popular tool for evaluating surface quality. It uses aggregation techniques that allow conversion of extensive data into single value or index. Globally, the WQI has been applied to evaluate (surface and groundwater) based on local criteria. Since its development in 1960s, it become due generalised structure ease-of-use. Commonly, models involve...
Surface water quality is degraded due to industrialization; however, it one of the widely used sources for supply systems worldwide. Thus, polluted creates significant issues health end users. However, poor attention and concern can be identified on this important issue in most developing countries, including Sri Lanka. The Kelani River Lanka heart whole Colombo area has intake drinking purpose...
Web Quality Index (WQI) for official tourist destination websites. Proposal for an assessment system
The quality of drinking water is an extremely important factor in public health. main sources the Kingdom Saudi Arabia (KSA) are bottled water, purified groundwater, and desalinated seawater. This study aimed to assess evaluate performance purification plants Al-Hassa with aid index (WQI). A total 150 samples were collected from 30 plants. physiochemical characteristics including pH, TDS, EC, t...
The present study was carried out near an industrial area with a high-density urban population and large-scale agricultural activities. These anthropogenic activities lead to groundwater pollution depletion of the water table. This attempted classify sources hydrochemical facies that help ensure suitability for agriculture drinking. Irrigation indexes, quality index (WQI), principal component a...
In this study water quality was indicated in terms of Water Quality Index that determined through summarizing multiple parameters test results. This index offers a useful representation the overall for public or any intended use as well indicating pollution, which are management and decision making. The application (WQI) with ten physicochemical performed to evaluate Euphrates River drinking us...
