Study of the ground water quality in Hodeidah is an essential ingredient for a healthypopulation. In this research, study of drinking water samples for eight water sources wells in theQuti field has been achieved. The purpose was to a certain the quality of water from thesesources, the physical properties such as pH, electrical conductivity (EC) and total dissolvedsolids (TDS), showed the varia...

Background: Reverse Osmosis (RO) is an increasingly common method of desalination. A full scale water desalination system by membrane technology (RO) evaluated in a southern city (Jask) in Iran. Methods: First, data collection on water supply and network were performed. Analysis on most of the water quality parameters (Turbidity, pH, EC, Cl-, Na+, Alkalinity, Ca, Na, K, No3, No2, Fe, Mg, Mn, NH...

Sulfate (SO42?) has been found in elevated concentrations on the surface of Mars and linked to oxidation volcanically derived sulfur (S) past, with best examples hydrothermal S-rich deposits Gusev crater. However, mechanisms volcanic S are unclear due lack abundant molecular oxygen (O2) Martian atmosphere. To address this uncertainty, we investigated hydrogen sulfide (H2S) SO42? O2-depleted aci...

in the present study, 45 rainwater samples were collected from february to december 2012 on event basis in east bokaro coal mining environment. physico-chemical and major ionic compositions of rainwater samples as well as water soluble major ion composition were analyzed to employ principle component analysis for source identification. the average ph value was recorded 6.1 and varied from 5.1 t...

Over the years, there has been an obvious pollution problem in Lagos area, Nigeria with high population of over eleven million and the near absence of waste management infrastructures. Concentrations of some pollution parameters and trace elements (temperature, pH, salinity, SO42-, NO3-, PO43-, F-, DO, BOD, COD and coliform, Cr, Co, Ni, Ag, Cd and Pb) were determined from water bodies of Isolo ...
