Michigan cherished Great Lakes, clean waters face threats from all sides

Flint was a wake-up call about access to clean water. Since that crisis, numerous new threats have emerged to Michigan waterways, from PFAS to corporate extractions. (Shutterstock image)

With 3,288 miles of Great Lakes coastline and 76,439 miles of rivers and streams, Michigan is practically defined by its access to clean, fresh water.
Michigan state regulators聽consider the open waters聽of the Great Lakes and inland waters in either 鈥渆xcellent鈥 or 鈥済ood鈥 condition, despite significant trouble spots around urban and heavily farmed parts of southern Michigan.
But waters face a host of challenges, from toxic threats such as PFAS chemicals to rising Great Lakes waters and continued controversy over the aging Line 5 oil pipeline under the Straits of Mackinac, which connects lakes Huron and Michigan.
Flint fallout
Michigan challenges were thrust into the national spotlight during the聽Flint water crisis, when the city water supply was contaminated with lead after a state-appointed emergency manager ordered a switch in Flint drinking water source.
After the emergency, Michigan adopted the nation strictest laws for lead in drinking water, requiring utilities to replace all the state roughly 500,000 lead service pipes within 20 years. That could cost upward of $2.5 billion, and leaders of municipal utilities contend the measure is an unfunded mandate.
PFAS chemicals
Michigan has been among the leaders nationwide in testing for PFAS, chemicals that have seeped into water supplies nationwide.
Per- and polyfluoroalkyl substances (PFAS), used in nonstick, waterproof products such as Teflon, are linked to cancer and were used at as many as 11,300 Michigan fire stations, landfills, industrial sites, military bases, airports and other locations, according to state estimates.
Michigan is聽suing manufacturers to recover cleanup costs聽and proposing standards over聽how much are dangerous to water systems, since the federal government lacks such rules.
Line 5, Nestl茅
Two controversies highlight the debate about corporate handling of public resources: the Line 5 oil pipeline and Nestl茅 withdrawals of 400 gallons of water a minute in central Michigan for its Ice Mountain bottled water.
A 66-year-old pipeline, Line 5 carries聽23 million gallons of oil聽and natural gas liquids each day 645 miles from Superior, Wisconsin, to Sarnia, Ontario. Environmental groups fear a leak to the pipeline would cause an ecological disaster in the lake.
The pipeline owner, Enbridge, said that highly unlikely 鈥撀 and wants to protect the pipeline at the Straits of Mackinac with a protective concrete tunnel. Michigan Democratic leaders 鈥撀 Gov. Gretchen Whitmer and Attorney General Dana Nessel 鈥 are聽seeking to shut down聽the line by challenging the tunnel in court.
Nestl茅, meanwhile, sparked a national outcry after Michigan regulators in 2018 approved the global conglomerate permit to increase extractions and take more than 210 million gallons of water per year from its wells.
Other water woes
- The Great Lakes are at or near record highs, just years after record lows. Many fear climate change causes extreme swings, worrying that more increases would harm not only homeowners but infrastructure along Lakes Michigan and Huron.
- Invasive species such as zebra mussels cause more than $100 million in damages to the Great Lakes,聽studies have shown, and federal officials fear that far more damage could come if Asian carp reach the lakes.
