This critical review presents the key factors that control the occurrence of natural elements
from the uranium-and thorium-decay series, also known as naturally occurring radioactive …

The safe disposal of liquid wastes associated with oil and gas production in the United
States is a major challenge given their large volumes and typically high levels of …

Groundwater has long been an active area of research driven by its importance both as a
societal resource and as a component in the global hydrological cycle. Key issues in …

The study of coastal groundwater has recently surfaced as an active interdisciplinary area of
