Stable Isotopes Reveal Sources Of Chinese Tap Water

How much do you know about your tap water? Does your tap water come from groundwater or surface water sources? Actually, it is not an easy task to identify the water sources using common chemical and biological methods. In the past decade, the stable hydrogen and oxygen isotope ratios in tap water have aroused attention in water resource studies, such as regional water use and source diagnosis, which is not always obvious from traditional water management data. Additionally, environmental information...

Comparability Of Meteoric Water Lines: Daily, Monthly, Or Annual Data?

The stable isotopes of hydrogen (δ2H) and oxygen (δ18O) have been widely applied in hydrology. The equation relating δ2H to δ18O in precipitation, also defined as a meteoric water line, can provide a reference point for interpretation of stable isotopic compositions of a range of water samples in an area. Influenced by many spatial and meteorological factors, the slopes and intercepts of meteoric water lines vary depending on location. It is not difficult to determine a meteoric water line using...
