We spend a lot of money to control sea lampreys. The U.S. and Canada spend $21 million dollars a year to keep them in check.

 

The invasive fish drills holes into big fish like trout and salmon, and drinks their blood and body fluids. A single lamprey can kill 40 pounds of fish.

 

Managers are always looking for new ways to control the blood suckers and keep tabs on where they are in the Great Lakes system.

 

Now, scientists are testing the idea of using environmental DNA – or eDNA. It’s a tool that’s been used a lot to see if Asian carp are in a river or lake; it detects genetic material from the fish.

There’s now more evidence that manmade chemicals can spread far and wide.

 

Researchers have found a chemical called PFPIA in cormorants, northern pike and bottlenose dolphins. The chemical has been used in pesticides, and it belongs to a group of chemicals called perfluorinated acids. They’re used to make cookware non-stick and make carpets stain resistant.

You can thank a honey bee for pollinating about one of every three bites of food we eat. But as you’ve likely heard, bees are in trouble.

They’re getting hit hard by pesticides and diseases and pests, and they’re losing habitat.

Two Grand Valley State University professors are using technology to track the health of hives in a new way.

Reviving Michigan's coastal marshes

Most visitors to northern Michigan are looking for sugar sand beaches on the Great Lakes. But if you’re a spawning fish or a migratory bird, you might be looking for a coastal marsh.

The Great Lakes used to be lined with coastal marshes that were full of native plants and wildlife. But in lower Michigan, many of these places been drained, plowed, polluted and, more recently, overrun by exotic plants from other parts of the world.

 

Some conservation groups are working to restore and protect the marshes we have left.

Every day, you and I burn up all kinds of things.

We burn gasoline to get to work, mow the lawn, or fly to a conference. We burn natural gas, coal, or heating oil to heat our homes. And we burn up coal or natural gas when flipping on that light switch.   

Whenever we burn stuff, we release carbon dioxide into the atmosphere.

Burned a gallon of gas driving around town? You just put around 20 pounds of CO2 into the air.

That CO2 traps heat, and all the burning we do is causing the planet to warm dramatically.

The ESPniagara, aka "lab in a can."
NOAA GLERL

Scientists launched a kind of underwater robotic tool in Lake Erie this week to test the water for toxins.

Timothy Davis is a researcher with NOAA's Great Lakes Environmental Research Laboratory.

“We affectionately call it a lab in a can,” he says.

He says this tool takes water samples to test the levels of a toxin in the green blooms of cyanobacteria that've been showing up in the lake each year.

The plaintiffs say older, poor and impoverished people in Flint aren't getting enough water

Should a judge force the government to deliver bottled water, door to door, to everybody in Flint?

The Flint water crisis has gone to federal court: a group of activists say the state’s efforts really aren’t reaching a lot of people – especially older, sick, or low-income people.

There’s several plaintiffs here:  a group called the Concerned Pastors for Social Action, the Natural Resources Defense Council, and a Flint resident/activist named Melissa Mays.

The Canadian government has confirmed that, for the first time, a fertile grass carp has been caught in the Canadian waters of western Lake Erie.

Grass carp are considered less of a threat than bighead and silver carp (but grass carp can eat a lot of aquatic plants) and for a long time, people thought the grass carp in the lakes were sterile. But lately, fertile grass carp have been turning up.

The vast majority of climate scientists agree climate change is happening and it’s mainly caused by people.

A new study looks at how middle school students' beliefs about climate change are shaped by their teachers’ own beliefs.

State and federal officials are celebrating the completion of a twenty-year river cleanup effort in southeast Michigan.

The River Raisin was once one of the most polluted rivers in Michigan. It will soon be clean enough for both commercial navigation and recreational use.

The Environmental Protection Agency says the cleanup effort is in its final stage, which is set to be finished by the end of October.

Our cities are especially vulnerable to climate change. More than 80% of people in the U.S. live in cities, so things like flooding and heat waves can affect a lot of people at once.

But city planners don’t always have a good handle on the risks their cities face.

State officials in Ohio want to list parts of the Lake Erie shoreline and drinking water intakes in the lake as impaired. They want to do this because of the toxic blooms of cyanobacteria that have been growing on the lake every year. The blooms are fueled by excess nutrients, mostly phosphorus, that get into the lake from farms and sewage treatment plants.

An impaired listing under the Clean Water Act sets pollution limits and outlines what has to happen to clean up that pollution.

What do you know about moths, besides that they’re attracted to your porch lights? It turns out researchers still have a lot to learn about the many species of moths and the role they play in ecosystems.

Ryan Utz is an assistant professor of water resources at Chatham University. But right now, he only has eyes for moths.

 

“It feels like just a wall of gems because you never know what you’re going to find," he says.

Recycling programs in Michigan have run into some problems.

Some, like the University of Michigan's program, cut back on what they take. And businesses are paying some of the highest prices they've seen in recent years to have their leftover material recycled.

The folks at Ventura Manufacturing wrote to us to say they're having a hard time finding a good recycling option for their facility in Zeeland.

Tougher pipeline safety rules could be a tough sell

There's a building boom for pipelines all across the country right now, and that’s created anxiety about new pipelines close to where people live and work. While the federal government is trying to ratchet up safety rules, there are limits on what these new rules can do.

A team of scientists from the U.S. and Canada are setting sail on Saturday. They’re heading out on a research trip to sample plastic pollution in all five of the Great Lakes.

It's part of a project called EXXpedition Great Lakes: seven research boats led by female scientists who are studying microplastic pollution. Microplastic pollution is made up of plastic particles that are five millimeters in diameter, or smaller.

Endangered species are waiting in long lines for the federal government to make a decision.

That’s the conclusion of a study in the journal Biological Conservation on wait times for listing a species under the Endangered Species Act.

Plants usually don’t get as much love as cute animals. Sometimes it’s hard to get people fired up about an endangered plant.

But Jane Kramer’s trying to do that anyway.

She’s a fine art photographer. She takes photos of the shadows of rare or threatened plants, and then prints them on paper she makes out of invasive plants like garlic mustard and purple loosestrife.

Researchers found that cardinals might be helping to shield people from West Nile virus in some regions of the country.

Robins are considered "super-spreaders" of West Nile virus. They’re especially good at passing the virus to mosquitoes, and mosquitoes, of course, can then pass it to us.

It turns out a different bird species – cardinals – might be shielding people from getting the virus in some parts of the country.

Marc Edwards/Flint Water Study

Remember all that smelly, brownish-orange water that was coming out of people’s taps in Flint?

That was Flint’s water system – the actual pipes – corroding and breaking down, at a rate 15 times faster than they normally would have, says Virginia Tech engineering professor Marc Edwards.

The first six months of this year were the warmest on record. This week, we heard about a deadly anthrax outbreak in Russia that's thought to be the result of permafrost thawing.

A new survey finds that fewer Americans doubt that climate change is happening, but it continues to be a highly polarizing issue.

Now, you can type in your zip code and see the future.

At least, you can see how hot it’s probably going to be.

The National Oceanic and Atmospheric Administration has updated the tool it calls Climate Explorer. It’s an interactive website loaded with data for each county in the U.S.

David Herring is with NOAA’s Climate Program office. He says you can type in your city or zip code, and see projections: for example, how many days might be hotter than 95 degrees Fahrenheit.

The hunt for methane gas leaks goes high tech

Scientists are trying to find leaky gas wells and pipelines. They want to know how much of this infrastructure is leaking methane - a potent greenhouse gas.

“There’s a blue line with the green line, but you can’t even see it anymore because the fit is spot on. We’re ready to do our calibrations,” she says.

Consumers Energy in April closed seven of its coal-burning units.

DTE Energy plans to shut eight of its coal-burning units by the year 2023.

Mark Barteau is Director of the University of Michigan Energy Institute.  He says eventually, coal is going away because natural gas, wind and solar are more cost-effective - as well as being better for public health and the planet.

Toxic blooms of cyanobacteria have been forming on Lake Erie for several years now.

A kind of cyanobacteria called Microcystis produces a toxin that can hurt pets and make the water unsafe to drink. Back in 2014, Toledo had to shut down its drinking water supply because of the toxin.

The states around the lake – and Ontario - are working to cut back on phosphorus. It’s a nutrient that runs off from farms and wastewater treatment plants and makes those toxic blooms grow like crazy.

The Great Lakes Commission just launched a new pilot program with Michigan, Ohio, Indiana and Ontario. It’ll be a trading program for phosphorus, and they’re calling it the Erie P Market.

Proposed salmon cuts upset some fishermen

A proposal to reduce the number of Pacific salmon stocked into Lake Michigan has upset some sport fishermen. The Michigan Department of Natural Resources recently took a poll of its advisory group.

It found about 40% of those surveyed were against the plan.

Millions of king salmon have been planted in Lake Michigan since the 1960s, as many as seven million fish a year at the peak. That has created a booming sport fishery.

But there is not much food for salmon in the lake these days, so fewer fish are being stocked.

There are several potential sources of lead in your home plumbing that can get into your drinking water.

  • The service line connecting the water main to your house could be made out of lead
  • The solder in your plumbing could have lead in it
  • And older brass faucets and valves can contain lead

So how do you figure out what you have in your house?

This question has been nagging at me for some time. At our house, we drink the water straight from the tap.

Industries in the U.S. have made some progress cutting greenhouse gas emissions over the past couple of decades. But emissions are up from the transportation sector. This matters because transportation is the nation’s second-largest source of the emissions that are causing climate change.

The U.S. and Canada have added polybrominated diphenyl ethers to their list of "Chemicals of Mutual Concern."

PBDEs are a class of flame retardants in furniture, electronics, car seats and the padding under our carpets. But the toxic chemicals don’t stay put. They leach out and build up in people and in wildlife.
