Serving Through Science: Dr. Emily Lesher gathers water samples in local schools to analyze for lead content.

In addition to her teaching, Dr. Lesher鈥檚 research and advocacy is having an effect. She has been meeting with officials from the Maine departments of Environmental Protection and of Education, representatives from water utilities and public school representatives to continue working on this problem.聽Read how Dr. Lesher and her students are tackling this issue.
