Groundwater pumping may have spurred deadly quake
Farmers drilling ever deeper wells over decades to water their crops likely contributed to a deadly earthquake in southern Spain last year, a new study suggests. The findings may add to concerns about the effects of new energy extraction and waste disposal technologies.

Nine people died and nearly 300 were injured when an unusually shallow magnitude-5.1 quake hit the town of Lorca on May 11, 2011. It was the country’s worst quake in more than 50 years, causing millions of euros in damage to a region with an already fragile economy.

Using satellite images, scientists from Canada, Italy and Spain found the quake ruptured a fault running near a basin that had been weakened by 50 years of groundwater extraction in the area.

During this period, the water table dropped by 250 meters (274 yards) as farmers bored ever deeper wells to help produce the fruit, vegetables and meat that are exported from Lorca to the rest of Europe. In other words, the industry that propped up the local economy in southern Spain may have undermined the very ground on which Lorca is built.

The researchers noted that even without the strain caused by water extraction, a quake would likely have occurred at some point.

Some scientists seeing climate-weather link
The worst drought in half a century has plagued two-thirds of the nation, devastating farms and stoking wildfires that scorched almost 9 million acres this year. Withering heat blanketed the East Coast and Midwest, killing scores of people and making July the hottest month ever recorded in the U.S. And in the Arctic this summer, polar snow and ice melted away to the smallest size ever observed by man.

Extreme events like drought, heat waves, intense rainfall, flooding and fires have prompted many people to reconsider the connection between the weather and the changing climate. Now, a handful of scientists are among them.

In a break with the mainstream scientific consensus, a few prominent climate scientists now argue that there have been enough episodes of drought and intense heat in the last 10 years to establish a statistical pattern of extreme weather due to global warming.

Sugar beet co-op fined for pollution
Minn-Dak Farmers Cooperative of Wahpeton, N.D., has taken corrective actions and paid a $70,000 penalty to the Minnesota Pollution Control Agency following an investigation into a complaint of smelly, polluted waters in the Rabbit River watershed drainage system.

In May 2011, the MPCA received a complaint of polluted water in drainage areas that flow to the Rabbit River in Wilkin County. Inspections by agency staff determined that pollution in the drainage system originated from Minn-Dak’s Lyngass, Yaggie and Hawes sugar beet storage locations. Discharges to the drainage system resulted from polluted runoff discharges from the storage sites.

The cooperative was cited for these discharges as well as for failing to immediately report them and take immediate steps to mitigate their impact.

In addition, MPCA staff found that regular inspections designed to help identify and-or correct potential stormwater runoff problems were not conducted in accordance with the company’s permit requirements; that errors were made in calculating, implementing and reporting the land application of waste beets; and that material errors were made in inspection reports and that reports failed to include sugar beet juice discharges during fall 2010.

Clean Water Council gets input on spending
Check out 179 pages of comments from 110 individuals and groups who offered suggestions to the Minnesota Clean Water Council on how the state should spend $185 million over the next two years to protect and clean up lakes, rivers and aquifers.

Recycle some bottles into your Levi’s
Most apparel companies work hard to give their clothes the sheen of sophistication or whimsy. Levi Strauss is trying hard not to.

When its latest line of jeans arrives in stores early next year, the pitch will be: “These jeans are made of garbage.” Crushed brown and green plastic bottles will be on display nearby. Eight of those are blended into each pair of Levi’s new WasteLess jeans, which are composed of at least 20 percent recycled plastic.

The WasteLess denim collection is part of a bigger push to reduce Levi’s environmental impact throughout the entire process of making jeans.

“We want to build sustainability into everything we do,” said Michael Kobori, the vice president of supply chain social and environmental sustainability.

Resource scarcity and increasingly volatile prices for cotton make this a necessity more than a choice. Plus outside groups are putting pressure on big consumer companies such as Levi’s to be stewards of the environment.

Illinois plans $1 billion for infrastructure
Gov. Pat Quinn launched a $1 billion initiative to upgrade sewer lines, water mains and water treatment plants across Illinois, some of them badly eroded after more than 100 years of service.

Timing the announcement to coincide with the 40th anniversary of the federal Clean Water Act, Quinn described his administration’s Clean Water Initiative as a jobs-creating effort to pull Illinois up from the nation’s lower rungs in terms of water safety.

Does fracking contaminate water?
Read a good q-and-a discussion of allegations that hydraulic fracturing of deep rock formations by gas and oil drilling operations contaminates groundwater. The review in the journal Nature focuses on a site in Wyoming where the EPA last year said it found evidence of contamination. Read a Bloomberg article on a recent EPA report concluding that its latest round of tests on Wyoming wells showed results consistent with previous findings that fracking probably caused groundwater contamination. Read the EPA report released Oct. 10.

Minnesota DNR calls for water conservation
Drought conditions are straining Minnesota’s water resources. The Minnesota Department of Natural Resources is urging everyone to adopt water conservation measures.

“Water is essential to our economy, our natural resources, and our quality of life,” said Tom Landwehr, DNR commissioner. “We are in the second year of a drought, and it is time for all of us to take water conservation more seriously.”

DNR is asking agricultural, commercial and industrial water users to stop outdoor irrigation and to implement conservation measures. Everyone who holds a DNR permit for water appropriation should review and abide by their permit conditions and begin conserving water as soon as possible.

“The drought conditions are sobering and call for a collaborative response,” Landwehr said. “At a time that per capita water consumption is decreasing nationwide, Minnesota’s water use per resident is actually increasing. We will need to work together to meet these challenges.”

Public water suppliers have been contacted by the DNR and reminded to implement appropriate conservation measures contained in their water supply plans. These could include water audits, leak detection, and promoting water conservation to their customers.

Howard Buffett calls for conservation compliance 
Farmer-philanthropist Howard Buffett said that stronger government action is needed to encourage farmers into compliance with better fertilizer, tillage and other conservation and environmental practices.

“We have a whole culture based on yield,” said Buffett, 55, who owns farmland in his native Nebraska, Illinois and Arizona as well as South Africa. One of several issues that caused a stalemate in this year’s farm bill discussions in Congress was over making conservation compliance a requirement for eligibility for federal crop insurance.

“Government has the biggest club, and if it doesn’t use it, there will be less good conservation practices,” Buffett said. Buffett, son of Omaha financier Warren Buffett, has emerged as a force in world agriculture through his foundation, which finances experimental work in Africa and other countries.

DNA suggests Carp have passed barrier to L. Michigan 
Even as Michigan lawmakers lambaste the U.S. Army Corps of Engineers for not moving fast enough to develop a permanent plan to stop Asian carp from swimming up the Chicago canal system and into Lake Michigan, genetic evidence that the fish are on the march continues to grow.

Tthe Army Corps announced it would send fishing crews onto the North Shore Channel of the Chicago River. The agency also will fish for Asian carp on a six-mile stretch of river in downtown Chicago.

The announcement was triggered after three separate sampling trips on the waterway showed DNA evidence of silver carp, which can be shed from a live fish from things such as mucus and feces.

The agency also announced that 17 of 57 samples taken on just one trip last month on the Chicago River near downtown tested positive for silver carp. Crews will be on the river  with electro-fishing boats and other sampling tools to chase the elusive fish.

The Army Corps maintains that a positive sample does not necessarily mean the presence of live fish. Officials note it could get in the water by some other means, such as barge bilge water, bird droppings or even the toilet flush of someone who happened to eat Asian carp for lunch.

EPA funds Lake Superior mercury research
The U.S. Environmental Protection Agency announced a $1.4 million Great Lakes Restoration Initiative grant to the Minnesota Department of Health to reduce mercury exposure risk for women and children who live along Lake Superior’s north shore. Excessive blood mercury levels have been documented in infants in this area. The funding will be used to improve health screening and to develop more effective fish consumption advisories.

The Grand Portage Chippewa Tribe and the Sawtooth Mountain Clinics in Grand Portage and Grand Marais, Minn., will participate in the project. Physicians affiliated with the clinics will survey consenting female patients of childbearing age about fish consumption and test blood mercury levels. Patients will also be counseled to promote safe fish consumption choices.

The work supported by the grant will build on an earlier EPA-funded study which was completed last year by MDH. In that study, 1,465 newborns in the Lake Superior Basin – including 139 infants from Wisconsin and 200 from Michigan – were tested for mercury in their blood. The study found that 8 percent of the infants had mercury levels higher than those recommended as safe by EPA.

UM seeks ‘greener’ lawns
Advocates of sustainability have often demonized lawn care for squandering water, adding fertilizers and herbicides to the environment, and increasing our carbon footprint through gas-powered mowing. But a new research project from the University of Minnesota could make both environmentalists and homeowners happier in the future.

Funded by a $2.1 million grant from the U.S. Department of Agriculture, the 5-year project is part of a national research effort aimed at improving specialty crops. Researchers will be investigating ways to develop turf grasses that require less water and mowing, and that stay green without extensive use of pesticides and fertilizers.

Girl Scouts work for water on Oct. 13
On Oct. 13, thousands of Girl Scouts in 49 counties in Minnesota and Western Wisconsin will celebrate the Girl Scouts’ centennial with a service project aimed at protecting lakes and rivers.

Some 36,000 girls, assisted by 18,000 adults, will clean up leaves, grass clipping and other debris from streets and storm sewer grates in their neighborhoods.

The project – the Girl Scouts’ Centennial Day of Service – is a Community Clean-Up for Water Quality. It is sponsored by 3M and was planned and organized by the Girl Scouts of Minnesota and Wisconsin River Valleys in partnership with the Freshwater Society and the Friends of the Minnesota Valley.

The goal is to prevent excess algae growth in lakes and river by eliminating the phosphorus, nitrogen and sediment that result from the breakdown of organic matter and flow – untreated — through storm sewers to surface waters.

UM to study Minnesota Valley land use
The University of Minnesota  has received a $4.3 million Water Sustainability and Climate grant over five years from the National Science Foundation to lead a study on the interactions between climate, water and land-use systems in the Minnesota River Basin.

The University of Minnesota-Twin Cities is the lead institution for this grant that involves researchers from institutions across the country such as the University of Illinois at Urbana-Champaign, Johns Hopkins University, Utah State University, University of Washington, Iowa State University, and the University of Minnesota-Duluth.

The researchers will develop a framework for identifying and predicting processes, locations and times that are most susceptible to accelerated change. This framework is envisioned to guide decision and policy making toward a healthy and resilient environment.
The research team chose the Minnesota River Basin as a location for the  research because it encompasses an extremely broad spectrum of natural and human-induced rates of change and sensitivity to land-use practices.

“This grant brings together some of the top scientists and engineers from across the country to study one of the most important issues of our time—water sustainability under climate and human stressors,” said Efi Foufoula-Georgiou, a civil engineering professor in the University of Minnesota’s College of Science and Engineering and lead researcher on the grant.

N.D. man ticketed for zebra mussels
Minnesota Conservation Officers Kipp Duncan and Jen Muller pulled into a parking lot in Two Harbors recently and couldn’t believe what they saw — a shopping cart covered with zebra mussels resting in the back of a pickup truck.

“They covered the entire outline of the cart,” Duncan said. “It was pretty amazing to look at. I’ve never seen anything with that many zebra mussels on it.”

The man driving the truck, Bruce A. Hinsverk, 51, of Wahpeton, N.D., told the officers he was on vacation and saw the shopping cart next to two Dumpsters on the Duluth waterfront. He planned to drive up the North Shore to Grand Marais before returning to North Dakota with the shopping cart.

Hinsverk apparently thought it would be cool to have the cart on display at his hair salon, Muller said. What Muller said Hinsverk didn’t know is that it’s against Minnesota law to transport or possess even one zebra mussel or other invasive species, let alone thousands of them.

Hinsverk was cited for unlawfully possessing or transporting a prohibited invasive species and given instructions on how to appeal the charge or pay the $500 fine.

State of the River report examines Mississippi

September 27, 2012

The Friends of the Mississippi and the National Park Service have produced an in-depth review of the Mississippi River in the Twin Cities area.

The report, issued Thursday, Sept. 27, examines the health and safety of the river’s water for the organisms that live in it and for the humans who drink it and swim and fish in it. The report describes the Mississippi as much cleaner than it was years ago, but still suffering from too much phosphorus, too much nitrogen and too much sediment.

It also describes a new danger: increasing concentrations of dioxins formed from triclosan, a chemical used in many anti-bacterial hand soaps, cosmetics and deodorants.

U of M research aims to clean fracking fluid

September 17, 2012

A team of scientists from the University of Minnesota’s College of Biological Sciences has received a $600,000 grant to study the use of bacteria to clean waste water from the hydraulic fracturing – fracking – of gas and oil deposits.

The research team plans to use a process originally developed to remove agricultural pesticides from soil and water.

The goal is to take waste water contaminated by the addition of chemicals for the drilling process and clean it to the point it can be re-use in fracking of other wells and to significantly reduce the overall amount of water used by the drilling industry.
