Michigan: Company released industrial chemicals into water

WIXOM, Mich. — An auto trim maker violated the law after releasing industrial chemicals into a river system northwest of Detroit, Michigan environmental officials say.

Michigan’s Department of Environment, Great Lakes, and Energy says its Water Resources Division issued citations Tuesday to Tribar Manufacturing in Wixom for discharging a plating solution containing hexavalent chromium into a sanitary sewer system the weekend of July 29.

The solution ended up at a wastewater treatment facility that sends wastewater into a creek that flows into the Huron River system.

Hexavalent chromium is a known carcinogen and can cause a number of health problems if someone ingests, touches or inhales it, according to Michigan’s Department of Health and Human Services.

Tribar Manufacturing was cited for failing to immediately notify the Department of Environment, Great Lakes, and Energy after discovering the discharge. The agency also alleges that the unauthorized discharge of pollutants interfered with the wastewater treatment process.

The agency said it is still investigating exactly how much chemical was released and why.

Tribar Manufacturing has until Aug. 20 to respond in writing to the notices, according to the state agency. The Associated Press called Tribar Manufacturing Wednesday afternoon but was unable to leave a message on the company’s voicemail system.

State health officials have said testing at 55 downstream locations in the Huron River system did not find any hexavalent chromium.

Health officials say people and pets should avoid contact with the Huron River in parts of Oakland and Livingston counties. It also advises that fish caught in that area should not be eaten.

Farmers digging into the eco-friendly powers of dung beetles in far north Queensland

A passing observer might think the cattle and dairy farmers of far north Queensland have been having very strangely by digging through their paddocks — elbows deep in cattle dung.

They are on the hunt for an insect that has one of the most unappealing and yet important jobs in the world: eating animal droppings.

Their search comes as soaring fertilizer prices and workforce shortages across Australia accelerate a movement towards natural, non-labor intensive alternatives.

The humble dung beetle offers a real solution.

It recycles effluent waste into organic fertilizer, eradicates flies, aerates the soil and increases water penetration — all while cheerfully munching on dung and asking nothing in return.

Beetles that specialize in eating cattle dung have been studied and bred extensively in both southern Queensland and southern states since they were introduced by the CSIRO in the 1970s.

But until now, there have not been any comprehensive long-term studies on how to breed and propagate species suited to northern Australia.

Some 15 farmers in far north Queensland have rolled up their sleeves to find out just what is living in the cow pats on their fields.

Cattle dung ‘attracts flies’

Among the participants is Gail Abernethy, who runs a small herd of cattle at a 36-hectare property at Wondecla on the Atherton Tablelands with her husband Victor.

She said she wanted to increase the population of dung beetles in the region, not only to reduce pasture fouling and fly outbreaks, but also to benefit productivity and the environment.

“There are native dung beetles, but they eat marsupial dung, so before the CSIRO back in the 70s and 80s introduced dung beetles from overseas, there was a lot of dung on the ground because it wasn’t being processed,” Ms Abernethy said .

“Cattle dung attracts flies, and that’s why the Australians had the fly salute, and had corks on their hats because there were so many flies.”

Ms Abernethy said dung beetles took the manure and buried it, which improved soil quality and created aeration of the soil, “so you’ve got less run-off from rainwater.”

“But there’s so little research and development being done in northern Australia, where all the cattle live,” she said.

A dung beetle for every season

Ms Abernethy began ordering dung beetles from southern breeders in 2014, but soon realized there was very little information about what species survived well in northern Australia at different times of year.

She and 14 other farmers obtained a Landcare grant to undertake their own research — and they have not been afraid to get their hands dirty.

“You take your shovel and you find a cow pat that’s at least 24 hours old, and put it in your bucket with some soil, and then empty some water into it, and they will float to the top in a graceful style,” Ms Abernethy said.

“We have collected beetles once a month for 12 months, and we now know we have nine separate species of introduced dung beetles and four predatory species.

“They’re the smaller ones who eat the fly larvae … and some of our beetles don’t live down south. They’re just up here in the tropics.”

Creating plant nutrients

South Australia’s Dr Bernard Doube is among the world’s leading dung beetle ecologists and is helping the group with beetle identification.

He said the study had revealed a particularly abundant population of one species of dung beetle, Onitis vanderkelleniwhich was thriving in the Atherton Tablelands.

“It’s got a very restricted distribution up here and hardly anywhere else in Australia, but up here, it’s doing a great job,” Dr Doube said.

“It digs a tunnel to about 20 centimetres and lines the tunnel with dung … and down below, the beetle puts perhaps half a liter of dung, a huge amount really, and lays a whole [lot] of eggs in it.

“The eggs hatch into larvae, and the larvae eat all of the dung, and then [produce] all this processed stuff, which is rather like compost.”

Dr Doube said it created a “great big pile of plant nutrients”.

“The roots grow down there, and you get increased production and increased carbon storage because it’s a relatively permanent change in the structure of the soil,” he said.

“And our experiences from southern Australia indicate that we get about a 30 per cent increase in productivity due to the dung burial activity of the beetles.”

Importantly, Dr Doube said the study had also revealed a gap in the winter population of dung beetles.

“What this project has shown is that we have quite a diversity of beetles here, and they are active during the summer,” he said.

“But at this time of the year in autumn and winter, although there are some beetles present and they’re burying dung, they’re not very common.”

Dr Doube said the group would now seek further funding to import and breed a species of beetle called Onitis caffer, which was more active during autumn and spring.

“We hope that we can get some financial support to establish a dung beetle importation program again, bringing in this particular beetle, which is going to be most beneficial, in my view,” he said.

Kentucky Flooding: Officials call for critical recovery supplies as dozens are found dead in flooding and death toll is expected to rise



CNN

As the death toll in flood-stricken areas of Kentucky continues to rise, rescue workers and officials are focused on recovering missing people in several counties and coordinating vital aid for thousands of displaced residents.

At least 28 people, including four children, have died due to severe flooding that struck parts of Kentucky last week, Gov. Andy Beshear announced Sunday. The governor told NBC’s “Meet the Press” that he believes recovery crews are “going to be finding bodies for weeks, many of them swept hundreds of yards, maybe a quarter-mile plus from where they were last.”

While reading a breakdown of those killed in each county during a news conference Sunday, Beshear became visibly emotional when he reached the four children dead in Knott County, where 15 people have been found dead.

“It says ‘minor,’” the governor said looking at the list. “They are children. The oldest one is in second grade,” Beshear said.

The flooding – which swelled onto roads, destroyed bridges and swept away entire homes – displaced thousands of Kentuckians, according to the governor. It also knocked out vital power, water and roadway infrastructure, some of which has yet to be restored.

There was risk of flash flooding Sunday night into Monday morning, according to the National Weather Service. A slight chance of excessive rainfall is possible throughout the affected region on Monday and Tuesday. Conditions are expected to begin improving Monday, but the region could receive two-day totals of up to two inches of rain. Some areas could see more.

In Perry County, as many as 50 bridges are damaged and inaccessible, according to county Judge Executive Scott Alexander.

Debris surrounds a badly damaged home near Jackson, Kentucky, on July 31, 2022.

“What that means is there’s somebody living on the other side or multiple families living up our holler on the other side that we’re still not able to have road access to,” Alexander said.

Kentucky State Police are still actively searching for missing residents in several counties and ask that families inform law enforcement if their loved one is missing.

Search and recovery efforts could face yet another obstacle as temperatures are expected to soar Tuesday and through the rest of the week, placing crews, volunteers, displaced people and the area’s homeless population under pressing heat.

As the climate crisis fuels more extreme and frequent weather events, several areas of the US are currently experiencing flash flood risk, including swathes of the desert Southwest, Knoxville, Tennessee, and Tucson, Arizona.

State officials are immediately focused on getting food, water and shelter to the people who were forced to flee their homes.

Power outages and storm damage left 22 water systems operating in a limited capacity, a Sunday news release from the governor’s office said. More than 60,000 water service connections are either without water or under a boil advisory, it said.

Nearly 10,000 customers in the eastern region of the state were still without power as of early Monday, according to PowerOutage.us.

Officials overseeing the recovery efforts say bottled water, cleaning supplies and relief fund donations are among the most needed resources as the region works toward short and long term recovery. FEMA is providing tractor trailers full of water to several counties.

Volunteers work at a distribution center of donated goods in Buckhorn, Kentucky.

“A lot of these places have never flooded. So if they’ve never flooded, these people will not have flood insurance,” the mayor of Hazard, Kentucky, Donald Mobelini told CNN Saturday. “If they lose their home, it’s a total loss. There’s not going to be an insurance check coming to help that. We need cash donations,” he said, referring to a relief fund set up by the state.

Beshear established a Team Eastern Kentucky Flood Relief Fund to pay the funeral expenses of flood victims and raise money for those impacted by the damage. As of Sunday morning, the fund had received more than $1 million in donations, according to the governor.

The federal government has approved relief funding for several counties. FEMA is also accepting individual disaster assistance applications from impacted renters and homeowners in Breathitt, Clay, Knott, Letcher and Perry counties, the governor said, noting he thinks more counties will be added to the list as damage assessments continue.

Though the recovery effort was still in the search-and-rescue phase over the weekend, Beshear said in a news conference Saturday that he believes the losses will be “in the tens if not the hundreds of millions of dollars.”

“This is one of the most devastating, deadly floods that we have seen in our history,” Beshear told NBC Sunday. “It wiped out areas where people didn’t have that much to begin with.”

And it wasn’t just personal possessions washed away by the floodwaters. A building housing archival film and other materials in Whitesburg, was impacted, with water submerging an irreplaceable collection of historic film, videotape and audio records that documented Appalachia.

Appalachian filmmaker Mimi Pickering told CNN that the beloved media, arts and education center, Appalshop, held archival footage and film strips dating as far back as the 1940s, holding the stories and voices of the region’s people. Employees and volunteers were racing to preserve as much material as they could.

“We’re working as hard and fast as we can to try to save all that material… The full impact, I don’t think you have totally hit me yet. I think I don’t really want to think about it,” Pickering said. She noted the Smithsonian and other institutions have reached out offering assistance.

The extensive loss Kentuckians are suffering will likely also take a mental toll, Frances Everage, a therapist and 44-year resident of the city of Hazard told CNN. While her home de ella was spared, she said some of her friends de ella have damaged homes or lost their entire farms.

“When you put your blood, sweat and tears into something and then see it ripped away in front of your eyes, there’s going to be a grieving process,” Everage said. “This community will rebuild and we will be okay, but the impact on mental health is going to be significant.”
