Arsenic Mobilization in Groundwater. Edition No. 1
VDM Publishing House, June 2009, Pages: 248
Naturally occurring arsenic in groundwater has
emerged as a global problem. Millions of people
throughout the world are affected by arsenic
poisoning in drinking water. However, very little
work has been conducted to understand
hydrogeochemical dynamics, and the transport of
arsenic. We use a small region in Bangladesh, where
high levels of arsenic have been found, as the study
area. We carried out various field experiments,
laboratory analyses, and numerical modeling to
investigate the geochemical and hydrological impacts
on arsenic mobilization in groundwater. The insights
offered by our “Pond Hypothesis” on the mobilization
of arsenic and its transport to depth, are pertinent
not only to the study area, but also to the regions
throughout the Bengal basin and beyond, where
similar geochemical and hydrological characteristics
prevail. This work addresses some of the important
questions related to arsenic contamination in
groundwater, and should be especially useful to
professionals in Environmental science and/or
engineering, or anyone else who may be interested in
learning about arsenic mobilization in groundwater.
