The occurrences of contaminants including antibiotics, other pharmaceuticals, and personal care products in the environment have gained increasing attention in recent years because of their potential health and ecological impacts. However, serious gaps remain in our understanding of these contaminants and the significance of the threats they may pose, such as to drinking water. Through this appropriation scientists at the University of St.
Common carp, introduced from eastern Europe over a century ago, are an invasive species in Minnesota that adversely affect water quality and aquatic communities, particularly in shallow lakes and wetlands. While solutions for suppressing common carp reproduction and abundance are emerging, controlling the movement of common carp, and therefore preventing reinfestation, has so far proved difficult.
Native trout require clean, cold water that usually originates from springs, but the springs feeding the 173 designated trout streams in southeastern Minnesota are under increasing pressure from current and expected changes in land use. This joint effort by the University of Minnesota and the Minnesota Department of Natural Resources is working to identify and map the springs and the areas that feed water to these springs and to learn how these waters might be affected by development and water use.
