The environment around us can be impacted by hazardous materials, also known as contaminants, in ways that may affect our health and wellbeing. New contaminants in our water, air, and soil are referred to as emerging contaminants. They present unique challenges when it comes to protecting our natural resources and ourselves, as our knowledge of their properties is limited and constantly changes as we learn more about them. The Natural Resources Institute is dedicated to increasing access to information about emerging contaminants and collaborating with partners to foster better understanding of emerging contaminants in Wisconsin.
