Although surface water constitutes less than 1.5% of freshwater supply, historical development of surface water sources continues to mark the landscape. However, over- exploitation of groundwater is now at its highest, and 25% of the world’s 1.7 billion population live in water scare regions. As glaciers and snowpack disappear due...
Groundwater is often misunderstood because of its subsurface nature. Consequently, policies intended to govern the resource are fragmented as is evident in the Supreme Court case between Mississippi and Tennessee. Here, disagreements over ownership and the scientific-hydrogeological scope of groundwater in the Memphis Sand Aquifer have led to an 11-year...
Groundwater resources have become seriously threatened
due to improper use by industrial, municipal, and even public
sectors. Widespread contamination of aquifer systems has
jeopardized human health and the environment and methods for
restoring these systems are needed. Biological and chemical
in situ remediation, where contaminants are degraded within
This study was undertaken to gain further
understanding of the subsurface hydrology for a stream-adjacent
riparian area in Western Oregon's Coast Range.
Spatial and temporal fluctuations of the free water
surface of a toeslope, adjacent riparian area, and stream
channel in a forested terrace reach were monitored over a
In order to determine how contaminants from pharmaceutical, agriculture, and industry will move through groundwater systems, it is imperative to further our understanding of the relationship between physical, biological, and chemical properties of aquifers and transport and transformation of these products. Several studies have explored how heterogeneities in groundwater systems...
Groundwater is a vital resource and efforts must be made to protect its quality. In certain areas, its quality has been
threatened by the introduction of oil and gasoline, many times originating from underground storage tanks. Massachusetts has
directly reacted to this concern about groundwater quality by promulating a Massachusetts...
Enzymes play an important role in the environment, they breakdown natural-occurring
and anthropogenic molecules so that they can be transported into cells and
utilized. Enzyme assays are routinely used in soil science and oceanography to measure
the activities of specific processes and to serve as general indicators of microbial activity....
