Camp Riley Water Sample Collection
Dr. Jinelle Sperry, a wildlife biologist with the U.S. Army Engineer Research and Development Center’s Construction Engineering and Research Laboratory, collects a water sample at Camp Ripley in Minnesota. Sperry’s team uses water samples, as well as those samples taken of soil and air, around military training lands and those around USACE civil works projects, to search for any threatened or endangered species.
