A team led by Michael Sadowsky, PhD, has created a tool designed to help public health officials better understand sources of contamination in our waterways. Sadowsky, a microbiologist, is the director of the BioTechnology Institute, a Consortium member. According to the Minnesota Pollution Control Agency, 40% of Minnesota’s lakes and streams are impaired, with fecal contamination becoming a growing concern. Improved DNA sequencing technology has made it possible for researchers to identify the source of contamination, which should allow for identification of the pollutant at its source. Sadowsky's group used SourceTracker, a software program developed by the UMN’s Knights Lab, to compare the various organisms found in water samples. To learn more, click here
