May 16, 2008 (Fri - 8:30 pm)	Arsenic in Ground Water Aquatic Chemistry and Mitigation through a Sustainable Filtration Technology Abul Hussam - George Mason University The presence of toxic levels of arsenic in groundwater of Bangladesh and in many parts of the world is now known to cause serious health problems including cancer. Arsenic is primarily present as inorganic forms, where arsenite is the most toxic species. This talk will cover the aquatic chemistry of these species and the phenomena of natural attenuation of arsenic species in groundwater with experimental data and chemical equilibria. Finally, the chemistry of a simple and extremely efficient method for the filtration of arsenic species from groundwater will be discussed. The method uses a composite iron matrix as the arsenic scavenger material. This presentation will cover the present crisis of potable water in Bangladesh and its possible solution through the development of a sustainable filtration technology called SONO filter.

We'll explore some of them, and explore the relationships between cavers and mineral collectors. We all enjoy nature's beauty, and need to work together for our mutual benefit and understanding. Mineralogical Society of the District of Columbia (MSDC) at The National Museum of Natural History, Smithsonian Institution, Washington, DC - meet at the Constitution Avenue entrance and a guard will escort us to the Cathy Kerby room.
