Ann Arbor will shut down eleven of its city parks and nature areas after 3:00 p.m. every day from January 2-26, to permit sharpshooters to cull its abundant population of deer.

The ground is getting warmer at one of the state’s most contaminated sites.

The Environmental Protection Agency is using a process called thermal remediation to heat the soil and remove harmful chemicals at the Velsicol Chemical Corp. Superfund site in the town of St. Louis.

State environmental regulators say there's no risk to drinking water from contaminated water that spilled onto Interstate 696 last week.  

The green liquid that gushed onto the highway in Madison Heights on December 20th came from a closed factory, Electro-Plating Services. 

Good news for the city of Ann Arbor's drinking water - and the residents who drink it.

The city's Drinking Water Quality Manager, Sarah Page, says tests have detected no PFOS and PFOA compounds in the past five months.  PFOS and PFOA are two of the most worrisome PFAS compounds.

Some Detroit lawmakers and residents are keeping up the fight against the proposed expansion of a hazardous waste facility.

A state permit to allow U.S. Ecology to expand its Detroit operation ten-fold has been pending for years. The facility has stored and processed hazardous waste there for decades.

A popular state campground in West Michigan has put a hold on reservations for next year, over fears the campground could be flooded.

The Channel Campground sits on Muskegon Lake in Muskegon State Park.

Greg Sherburn is the supervisor of the park. He says normally, the campground would open up for Memorial Day weekend reservations about now. But he says the U.S. Army Corps of Engineers is forecasting high Great Lakes water levels into the spring.

Wolves on Isle Royale have begun to hunt and travel as a group. 

It’s part of a process park officials say could eventually lead to the formation of the island’s first new pack.

The partial collapse of a dock once contaminated with uranium into the Detroit River did not put dangerous levels of chemicals into the waterway, according to new test results from a southeast Michigan water utility.

The Great Lakes Water Authority tested both raw and tap water from its intake site near where the dock collapsed.

This week, the state began collecting PFAS-containing firefighting foam, known as Class B AFFF, that has been held in inventory by fire departments and commercial airports across Michigan.

According to Scott Dean, the spokesman for the Michigan PFAS Action Response Team (MPART), the effort is part of the state's $1.4 million plan to collect and dispose of about 35,000 gallons of the foam.

Wolverine Worldwide says it will pay nearly $70 million to build municipal water systems in two communities affected by PFAS contamination. 

The company used the chemicals to waterproof its shoes for years. The harmful chemicals contaminated the ground and entered into local wells.  The company says it will now pay to build the water systems to connect more than 1,000 properties to municipal water in Algoma and Plainfield Townships. It says the plan is part of a tentative agreement to resolve lawsuits involving the state and townships.

Congress has reached a final agreement on the annual national defense bill, the National Defense Authorization Act. This year’s bill includes a number of provisions to regulate the chemical family PFAS.

A new study out of the University of Michigan finds the bodies of migratory birds are shrinking - and it could be due to climate change.

The data was collected in Chicago over roughly 40 years. Researchers collected the bodies of birds that collided with buildings. The study uses some 70,000 birds covering 52 species as its data set.

State environmental regulators say tests done Friday show below-background levels of radiation at the site of a partial shoreline collapse into the Detroit River. 

A Windsor politician is calling for a bi-national investigation - and an environmental group is calling for the restoration of Michigan's "Polluter Pay" laws.

That's after part of a property owned by Detroit Bulk Storage collapsed into the Detroit River last week.  The collapse is initially being blamed on the weight of massive piles of sand, gravel and other construction materials the company is storing on site.

Scientists say gray wolves relocated to Isle Royale National Park are adjusting nicely to their new surroundings and finding plenty of prey.

Officials released findings Monday from observations of wolves that were captured on the mainland and taken to the Lake Superior park during the past year.

Officials from the federal, state and county government will be at a public meeting in Manistee on Tuesday to talk about shoreline erosion.

The meeting is at 6 p.m. Tuesday at the Little River Casino Resort in Manistee.

High water levels on the Great Lakes have caused flooding and erosion all along the Michigan coastline this year.

A majority of Michigan’s rivers have more water than usual for this time of year. That’s according to measurements from the U.S. Geological Survey.

Elevated water levels are causing issues for water infrastructure in the state.

The Department of Environment, Great Lakes, and Energy has discovered a toxic chemical in the air near a manufacturing plant in Howell.

According to a report by the federal Government Accountability Office, 60% of Superfund sites nationwide are threatened by floods, wildfires, and hurricanes that are becoming worse due to climate change.

In Michigan, twenty toxic sites are at a high risk of spreading due to increased flooding. The sites are scattered across the state, but most are located near former industrial hubs, including the Velsicol Chemical Company in St. Louis. 

Bouncing along a sodden farm pasture, Brad Johnson stopped his state vehicle when he came upon the newborn calf, or what remained of it.

The veteran wildlife handler had been to this patch of farmland in the western Upper Peninsula several times the previous fall, when a dozen calves from the Dykstra beef ranch were reported missing.

Scientists have concluded it's going to be more difficult than they initially thought to reduce phosphorus loads into Lake Erie by 40%.

That's the target set by Great Lakes states.

Phosphorus is a crop fertilizer that also encourages cyanobacterial blooms. 

Rebecca Muenich worked on a study to evaluate ways to control the blooms. 

Meunich is a former researcher at the University of Michigan's Graham Sustainability Institute, and now an assistant professor at Arizona State University.

The swirling liquid rushes into concrete channels behind a black chain-link fence.

“That is what sewage looks like,” says Nicole Pasch, who works in Environmental Services for the city of Grand Rapids.

Pasch is showing off the wastewater treatment facility, along with the various stages the sewage has to pass through before it can be sent back into the nearby Grand River, which flows into Lake Michigan.
