Collaborative research between scientists at Pacific Northwest National Lab (PNNL) and members of the Wilkins Lab was published today in Nature Communications. The study investigated microbial processes in the hyporheic zone (where river water and groundwater mix) of the Columbia River in Washington State. Bob Danczak in the Wilkins Lab performed microbial community analyses to determine which microbial groups responded to organic carbon inputs in this reactive zone. The study is published here
