It has turned up in several watercourses thanks to fish hobbyists dumping it or down the drain or whatever. It is a true "weed" in aquatic plants. Many jurisdictions have banned it for that reason. It should be discarded by dumping it on dry ground as in a compost pile or something where it will not be able to get into native waterways.
A very similar floating plant but I think much more beautiful is Salvinia auriculata. Native to South America, it has slightly larger leaves that have a wondrous silver reflection on the upper leaf surface. It grows very fast like duckweed but is a nicer plant I think.
