The present investigation provides data of some ions, namely Na+, Ca2+, NH4+, Cl-, NO3-, CN- and PO4(3-) on water samples of river Osun, selected rivers in the region and groundwaters. The pH, temperature, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH) and total carbon (IV) oxide (TCO2) have also been determined to asses the chemical status and pollution levels ...

The quality of the Siak River is gradually deteriorating with rapid socio-economic development in its tributary watersheds. S. Sibam and Air Hitam are part tributaries sub-region Pekanbaru City. Watershed City has been studied to determine relative pollution level water standards. Water measurements were carried out from January August 2022 at upstream, middle, confluence River. was measured us...

evaluation of surface water quality is a complex process undertakingmultiple parameters. converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.the main aim of this study is to plan effective water resources management system forkarun river by combination of ccmewqi and geographic information system ...

Sungai Mahakam have an important role in the survival of surrounding society. River is used by society for their household needs and also as a source raw water Perumdam Tirta Kencana, Samarinda City. In addition, this river means transportation lane barges that carrying coal. This condition allows pollution occurs river. Physical shows color cloudy growth hyacinth plants along Therefore, status...

Wise and sustainable uses of water resources are essential for an effective river-basin-management planning. Recent management strategy further addresses the fact that quantity and quality of water are closely interrelated, and both must be considered simultaneously for all water resources and water quality management practices. The aim of this paper is to explore the impacts of water resources...

This research (1) analyzed the content of Pb and Cd in water sediment; (2) physical chemical parameters water; (3) determined enrichment factor accumulation index sediments; (4) to identified quality based on Pollution Index (IP) STORET. The analysis was carried out using PCA (Principal Component Analysis) Pearson's correlation, conducted downstream section Musi River, Palembang, a random sampl...
