Hey Cafénistas…this is not an April Fool’s joke!
Come join us for Café Scientifique April 1, 2013 with Beth Weiman as she discusses her research that examines how groundwater attains its geochemistry. An important aspect of sourcing and maintaining our water supply deals with understanding how usable fresh-water resources gain their natural geochemistries. In not knowing from exactly where groundwater is gaining its geochemistry, the goal of this work tries to identify from where groundwater is gaining most of its geochemistry. In South and Southeast Asia, where many developing countries have natural arsenic contamination in their groundwaters, some work suggests that arsenic is sourced from an aquifer’s overlying soils, while others surmise it to be due to weathering of the underlying aquifer matrix. Based on past research showing that “younger” material weathers faster than “older” material, one objective of this work was to test whether aquifer age was a determinant parameter in arsenic groundwater chemistry.
We will continue to meet at the Cafe Via, near Herndon and Blackstone, where dinner will be served from 6:00 PM onwards, with the talk to begin at 7:00 PM.
