Coal ash ponds are contaminating groundwater across the country, but the consequences are unclear.
Avner Vengosh‘s research aims to link environmental geochemistry and isotope hydrology in order to trace the sources and mechanisms of water contamination and relationships with human health. Current research includes global changes of the chemical and isotopic compositions of water resources due to human intervention and contamination, salinization of water resources in the Middle East and Northern Africa, naturally occurring contaminants (arsenic, fluoride, boron) and radioactivity in water resources, the impact of coal combustion residues on the environment, and the impact of gas drilling and hydro-fracking on the quality of shallow groundwater.
Algae may hold the key to helping scientists devise a negative-emissions technology that produces electricity and provides protein for millions of people worldwide while simultaneously removing substantial amounts of carbon dioxide from Earth’s atmosphere and reducing deforestation.
Zackary Johnson‘s group broadly studies the abundance, diversity and activity of marine microbes. We are biological oceanographers, marine molecular ecologists, marine microbiologists and biogeochemists. Our research focuses on the marine cyanobacteriaProchlorococcus, the most abundant phytoplankton in the open oceans and an excellent model marine microbe, as well as the biotechnological applications of marine microalgae. We are at the Marine Laboratory as part of the Nicholas School of the Environment at Duke University.
