Caption: Researchers and students examine a sediment core sample from the bottom of Guatemala's high-mountain tropical Lake Atitlan to help trace the history of impacts on the lake's ecosystem. The lake’s water is contaminated with watershed runoff and waste water, which contributes to increased algae growth and suitable conditions for bacteria and pathogens that can proliferate and enter untreated drinking water
