Experimenting in the Snow (Amanda Grannas)

Chemist Dr. Amanda Grannas is describing an experiment she is currently conducting in the snowpack to understand what happens to different pollutants in different conditions when exposed to sunlight. She has prepared solutions containing known amounts of pollutants in clean water and snow melt water, and is placing them in the snowpack in sample vials. The samples are color-coded and will be exposed to sunlight for two weeks, while three samples from a buried blue container, which is the dark control, will be collected each day for comparison. The experiment aims to mimic what happens in snowpack and understand what kind of sunlight-driven chemistry occurs to these pollutants.
