The range of As concentrations found in natural waters is large, ranging from less than 0.5
μg l− 1 to more than 5000 μg l− 1. Typical concentrations in freshwater are less than 10 μg l …

Documenting the location and magnitude of groundwater recharge is critical for
understanding groundwater flow systems. Radioactive tracers, notably 14 C, 3 H, 36 Cl, and …

Building on the success of its 1993 predecessor, this second edition of Geochemistry,
Groundwater and Pollution has been thoroughly re-written, updated and extended to …

In contrast to most other fields of noble gas geochemistry that mostly regard atmospheric
noble gases as' contamination,'air-derived noble gases make up the far largest and hence …

Protecting or restoring aquatic ecosystems in the face of growing anthropogenic pressures
requires an understanding of hydrological and biogeochemical functioning across multiple …

Geochemistry has contributed significantly to the understanding of ground-water systems
over the last 50 years. Historic advances include development of the hydrochemical facies …

Measurements of 81Kr/Kr in deep groundwater from the Nubian Aquifer (Egypt) were
performed by a new laser‐based atom‐counting method. 81Kr ages range from∼ 2× 105 …

Groundwater Age is the first book of its kind that incorporates and synthesizes the state-of-
the-art knowledge about the business of groundwater dating-including historical …

Accelerator mass spectrometry (AMS) was born in the late 1970s, when it was realized at
nuclear physics laboratories that the accelerator systems can be used as a sensitive mass …

Noble gas radionuclides, including 81 Kr (t 1/2= 229,000 years), 85 Kr (t 1/2= 10.8 years),
