Meetings (currently virtual) take place the first Wednesday of every month for networking and informal discussion followed by a presentation on a relevant topic. TPFF is sponsored by Minnesota Sea Grant, the Natural Resources Research Institute, the Large Lakes Observatory, the Minnesota Pollution Control Agency and the USEPA Great Lakes Toxicology and Ecology Division.
