Government organizations, business groups and environment associations states bordering the Great Lakes – are urging U.S. presidential candidates to pledge their support – for cleaning up the waters in the region.

The groups have released a list of priorities – that include spending at least $300 million a year on the Great Lakes Restoration Initiative – which was established in 2009.

The document focuses on cleaning toxic hot spots, fighting invasive species, reducing farm and city runoff, and restoring wildlife habitat.

The petitioners also want funding for infrastructure improvements: to protect drinking water, reduce sewage overflows, and support locks and ports essential to maritime commerce.

The Council of Great Lakes Industries says candidates who say they want to support the region’s economy – should favour restoring and protecting the lakes as well.
