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
