The suitability of groundwater for drinking purpose with respect to BIS: 10500-1991standards is assessed through statistical analysis of the data and on the basis of seasonal variation in the quality of groundwater. The study was undertaken during 2010-2011. The samples are collected during post monsoon period from bore wells being monitored by the Andhra Pradesh Rural Water Supply and Sanitati...

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...

The Sinos River basin is located Northeast of the state of Rio Grande do Sul (29° 20’ to 30° 10’ S and 50° 15’ to 51° 20’ W), Southern Brazil, covering two geomorphologic provinces: the Southern plateau and central depression. It is part of the Guaíba basin and has an area of approximately 800 km, encompassing 32 municipalities. The objective of this study was to monitor water quality in the Si...

This study is used the water quality index (WQI), which generated by combining several parameters. gives a helpful representation of overall for public and all intended applications, it demonstrates that pollution beneficial in management decision-making. The Euphrates River was assessed order to determine drinking water. using WQI, includes ten physicochemical criteria. achieved submitting com...

The rapid development of industrialization and urbanization in the world impact increased water pollution. Human activities, such as dam constructions, excessive consumption, severance river flows, compaction riverbanks, use riverbed vegetation, disrupt flow alter original hydrological cycle. In response to these conditions, this study aims analyze quality status set up a watershed environmenta...

In this research, spatial – temporal variations of water quality in the fluvial components Hasana?a Stream Basin were evaluated by using Water Quality Index. Surface samples taken from seven stations selected on basin winter seasons 2019 and 2020. Eleven variables including dissolved oxygen, oxygen saturation, pH, electrical conductivity, total solids, salinity, turbidity, nitrate, nitrite, pho...

The surface water chemistry of Thiruvananthapuram Museum Lake was carried out in the period of February 2013 to January 2014. Correlation study of the parameters and overall CCME WQI (Canadian Council of Ministers of the Environment Water quality Index) was also prepared in the study for the lake water. The parameters analysed are cations such as Ca2+, Na+, Mg2+ and K+ and the anions like PO4-,...
