Soils overlying two porphyry Cu deposits (Spence, Gaby Sur) and the Pampa del Tamarugal, Atacama Desert, Northern Chile were collected in order to investigate the extent to which saline groundwaters influence ‘‘soil’’ chemistry in regions with thick Miocene and younger sediment cover. Soil carbonate (calcite) was analyzed for C and O isotopes and pedogenic gypsum for S isotopes. Soil calcite is...

The quality of groundwater has been severely impacted by urbanization around coasts. change in climate and land use patterns deteriorated the availability groundwater. One main issues contemporary research is dissolved organic carbon (DOC) water. influence DO, water level temperature on DOC was identified current study sampling 68 samples. analytical results revealed that ~18% total samples hav...

With the rapid development of economy, urbanization and industrialization gradually become an important driving force groundwater chemical evolution. In this study, Lanzhou City, which is one biggest industrial cities in northwest China, was selected to investigate impacts city on quality. Several hydrochemical methods together with principal component analysis (PCA) were used for hydrochemistr...

The study is required to evaluate the groundwater condition, such as finding relationship with lithology, determining facies of groundwater, and providing an overview present conditions, genetics, quality. This aims explain between lithology chemistry, quality, determination chemical determine genetic type groundwater. uses field survey methods random sampling techniques, measurements physical ...
