Energy potential of Irish groundwaters

Quarterly Journal of Engineering Geology, 1986
Summary The energy potential of Irish groundwater is assessed, and its sources summarized. The two sources of energy, solar and geothermal, are outlined. The manner in which water and energy are united is described. The recovery of energy may be from the warm springs areas, from the tepid springs areas or from the high yielding cold aquifers ...

Streaming potential and groundwater contamination

Exploration Geophysics, 2004
Measurements of streaming potential can provide a means for the detection and quantification of contaminants in groundwater prior to remediation. However, laboratory determinations of specific electrolyte properties are required for an adequate analysis of the hydraulic gradient in complex situations.

Natural Attenuation Potential of Phenylarsenicals in Anoxic Groundwaters

Environmental Science & Technology, 2009
The extensive production of chemical warfare agents in the 20th century has led to serious contamination of soil and groundwater with phenyl arsenicals at former ammunition depots or warfare agent production sites worldwide. Most phenyl arsenicals are highly toxic for humans.

Coal is a potential source of naphthenic acids in groundwater

Science of The Total Environment, 2009
Naphthenic acids, with the general formula C(n)H(2n+Z)O(2), are found in conventional petroleums and oil sands ores. These acids are toxic to aquatic life, so their discharge from petroleum processing into receiving waters must be avoided. In a previous study, naphthenic acids were putatively identified in groundwaters from two domestic wells that were

The New Potential for Understanding Groundwater Contaminant Transport

Groundwater, 2013
Abstract The groundwater remediation field has been changing constantly since it first emerged in the 1970s. The remediation field has evolved from a dissolved‐phase centric conceptual model to a DNAPL ‐dominated one, which is now being questioned due to a renewed ...

Review: Advances in groundwater potential mapping

Hydrogeology Journal, 2019
Groundwater resources can be expected to be increasingly relied upon in the near future, as a consequence of rapid population growth and global environmental change. Cost-effective and efficient techniques for groundwater exploration are gaining recognition as tools to underpin hydrogeological surveys in mid- and low-income regions. This paper provides

Delineation of groundwater potential zones and electrical resistivity studies for groundwater exploration

Environmental Geology, 2001
The electrical resistivity method is widely used in groundwater exploration studies. The method is particularly well suited to carry out groundwater studies in hard-rock terrains. The popular Schlumberger method of electrode configuration was applied in the study area.

Zeta Potential and Groundwater Quality

2013
Groundwater is the main source of drinking water in the eastern Croatia region and it contains elevated concentrations of natural organic matter, ammonia, arsenic, manganese and iron due to geological composition of soil. Natural raw waters often contain negative hydrophobic colloids and their stability depends on zeta (ξ) potential.

Potential for Groundwater Contamination by Algal Endotoxins

1981
Groundwater is an important resource which must be protected from contamination. Currently, 20% of the nation’s water supply is taken from groundwater. By the year 2000, this is expected to increase to 33% of the total water used in the United States.
