The city of Benton Harbor says lead continues to be problem in the city water supply.

The city says 12 of 47 homes tested since January of this year were above the federal action level for lead in the water.

Michigan could be among the first states to regulate a chemical known as GenX. It’s one of seven members of the PFAS family of compounds named by the Michigan PFAS Action Response Team, or MPART, as potentially requiring a maximum contaminant level for drinking water.

A state agency is supporting infrastructure upgrades and a public awareness campaign to boost recycling in Michigan.

The Department of Environment, Great Lakes and Energy announced more than $1.3 million in grants Monday to help Emmet County improve recycling technology and Kalkaska-based American Waste buy fiber equipment to produce higher-quality mixed paper recycling products.

Toyota says it will offset 40% of its global warming emissions from its North American operations within three years.

It will do that by buying contracts for new wind and solar projects.

The Toyota commitment is part of an encouraging trend, according to Greg Wetstone, CEO of the American Council on Renewable  Energy.

Activists are using this week’s 9th anniversary of the Kalamazoo River oil spill to dramatize their opposition to a proposed oil pipeline tunnel beneath the Straits of Mackinac.

The 2010 oil spill started when a pipeline near Marshall broke and started spewing crude oil.  The oil reached the Kalamazoo River, eventually spreading over about 30 miles of the river.   The cleanup took several years. 

Michigan and Ohio crews are on the lookout this summer for invasive grass carp.

The grass carp survey is being done by the Michigan Department of Natural Resource's Grass Carp Response Team.

Three binational Great Lakes coalitions announced their endorsement of the Invasive Mussel Collaborative as the “go-to forum” on developing solutions to the problems caused by invasive mussels in the Great Lakes. The three organizations are the Great Lakes Commission, International Joint Commission, and Great Lakes Fishery Commission.

The North American Great Lakes contain about one-fifth of the world’s surface fresh water. In May, new high water level records were set on Lakes Erie and Superior, and there has been widespread flooding across Lake Ontario for the second time in three years. These events coincide with persistent precipitation and severe flooding across much of central North America.

Yet another Michigan city is dealing with the issue of lead in tap water, as Highland Park officials announced on Wednesday that the results of state-mandated testing put them in violation of a new, tougher Lead and Copper Rule.

Water levels continue to rise in lakes and rivers across the region – including the Detroit River.

The Windsor Port Authority told the Windsor Star that people should avoid swimming in the river.

Researchers predict a large cyanobacterial bloom in Lake Erie this year.

But it will probably not be as bad as 2011 and 2015, when the blooms covered a large area of western Lake Erie.

Democratic presidential hopeful Jay Inslee is wading into a Great Lakes regional controversy by coming out against a proposed oil pipeline tunnel.

The Washington state governor opposes a plan favored by Enbridge to route the company's Line 5 pipeline through a tunnel that would be built beneath the Straits of Mackinac, the channel linking Lakes Huron and Michigan.

New research from the University of Michigan shows a lack of transparency when it comes to demographic data within environmental organizations.

This comes from a study of more than 12,000 environmental organizations around the country, ranging in size. The researchers say historically, these kinds of organizations have lacked racial diversity, and little information has been made available to the public regarding the demographic composition of these organizations.

Ever wanted to help researchers learn more about ticks and where people are being exposed to them? Now's your chance — and it's as easy as using the device that's likely already glued to the palm of your hand.

A bipartisan delegation of Michigan lawmakers from Congress are in Chicago today at the Brandon Road Lock and Dam. The delegation is there to see the facility and discuss possible solutions to keep Asian carp out of the Great Lakes.

Brandon Road Lock and Dam is considered by many to be the last line of defense from preventing carp from entering the Great Lakes. The Army Corps of Engineers released a plan in May that proposed a number of deterrents to meet the carp as they swim through the waterway, including noisemakers, electric currents, and an air bubble curtain. Huge populations of Asian carp, particularly bighead and silver carp, are reported to be only four miles from the dam.

Water levels in the Great Lakes have been rising, and that means shrinking shorelines.

Drew Gronewald is a hydrologist with the University of Michigan’s School for Environment and Sustainability. He says Lake Ontario broke an all-time high water level record in June, and all of the lakes broke records in May. He says Michiganders should take appropriate safety precautions in response to changes in water level and near-shore water circulation.

A Michigan science advisory workgroup released recommendations on Thursday for the state to implement some of the strictest standards in the nation for PFAS.

PFAS, or perfluoroalkyl substances, are a family of chemicals that have been found across the state and are linked to health problems including cancer. The Michigan PFAS Action Response Team received health-based recommendations from the workgroup for seven PFAS compounds. It recommends setting drinking water limits as low as six parts per trillion.

New results of soil testing done at the Leslie Science and Nature Center in Ann Arbor show elevated levels of arsenic, lead, and copper, among other heavy metals and semi and volatile organic compounds.

The center conducted testing back in May, and the results were released on June 20. 

HAZMAT crews worked Monday to clean up diesel fuel from the Huron River in Ann Arbor. The spill was caused by a fatal accident on eastbound M-14 involving two semi trucks.

A large and mostly dissatisfied crowd attended a Michigan Public Service Commission public meeting in Detroit on Thursday to comment on DTE's first Integrated Resource Plan (IRP).

The plan sets out DTE's short-term and long-term plan to ensure reliability and reduce carbon emissions, which are causing global warming.

Enbridge says it will continue its rock and soil sampling this week in the Straits of Mackinac. The company wants to build a tunnel to house a replacement section of its twin Line 5 pipelines in the Straits.

Governor Gretchen Whitmer halted state work on the project in March.

Ryan Duffy is a spokesman for Enbridge. He says the state permit needed to conduct the sampling was approved in January.

He says the state has confirmed that the sampling process can still move forward.

Piping plovers are an endangered species of bird that builds its nests on Great Lakes beaches. Its main habitat is the Sleeping Bear Dunes.

But some of the birds' nests are being washed away by high water levels.

Vincent Cavalieri, piping plover coordinator for the U.S. Fish and Wildlife Service, says the birds could be especially at risk this year. He says although the recorded number of bird pairs has increased since last year, the rising water is likely to cause problems during this year’s nesting season.
