This study integrates microbial analysis into an undergraduate chemistry class, offering students a hands-on approach to environmental research. We examined the soil along the urbanized Potomac River, discovering a mix of common marine microbes and others that are indicators of urban waste and pollution. Our findings provide valuable insights into the environmental impacts of urbanization on soil health and reveal the effectiveness of using modern genetic tools to teach students about real-world issues. This innovative educational approach not only deepens students' understanding of chemistry and ecology but also prepares them to be thoughtful, informed participants in addressing contemporary environmental challenges while shedding light on the state of the soil microbiome near and around the DC metro area.
