Geiss is the only candidate for the sixth State Senate District who is a League of Conservation Voters champion and who has a Sierra Club A grade. She is a consistent supporter of legislation and policies that protect our Great Lakes and clean air and clean water. Geiss is a member of the Council of State Governments Great Lakes Caucus and in 2016 was named a League of Conservation Voters (LCV) Legislative Champion.
She has also been vocal against expanding the specific gravity at the deep injection well site in Romulus and against the approval for the Wayne facility in Van Buren to accept radioactive fracking waste.
During January 2017, residents were concerned about water quality issues impacting part of her district and surrounding Downriver communities. Geiss, along with local and other Downriver State Representatives, immediately went to work to inform residents and provide common-sense advice until answers could be received; she diligently worked to get answers from the Great Lakes Water Authority (GLWA), which culminated in a town hall to dissect and discuss water issues in our region. Geiss and her Downriver colleagues listened to the people and responded with direct action immediately. While on the Commerce and Trade Committee, Geiss opposed the measure to loosen ballast water requirements for vessels traveling through the Great Lakes.
