Lake Winnibigoshish now designated “infested water”
Anglers and boaters must adhere to stricter rules on Lake Winnibigoshish near Deer River because the lake has been designated “infested waters” under state regulations.
The infested-waters designation was made May 7 because of an exotic species, the faucet snail, first found on the lake in 2007. The snail is a host for a trematode that has caused the die-off of hundreds of scaup and coots on Lake Winnibigoshish during the past two falls’ waterfowl migrations.
Winnie’s designation as an infested water will have broad implications.
“I think it’s a real big deal,” said Chris Kavanaugh, Department of Natural Resources area fisheries supervisor at Grand Rapids. “It’s important we get the word out to folks so they comply with the laws that are intended to reduce the risk of spreading invasive species to other waters.”

UM students work on clean water to India
A team of University of Minnesota-Twin Cities students from a civil engineering class are in India to share their ideas and plans for helping bring clean water to thousands of residents living in the slums of Mumbai — the same impoverished area that provided the backdrop for the Oscar-winning movie, “Slumdog Millionaire.”
The University of Minnesota students, who collaborated with students from the Indian Institute of Technology-Bombay, are winners of the first-ever Acara Challenge sponsored by the Minnesota-based Acara Institute, a non-profit institute that tackles global problems through sustainable business solutions.

Environmental fund closes down
John Hunting, an heir to the Steelcase office furniture fortune, always knew that his foundation, the Beldon Fund, would have a limited life span.
“I felt as an environmentalist that it was imperative to spend the money now, because it would be silly to wait for the future if there wasn’t going to be a future,” Mr. Hunting said in an interview the other day. “And I also felt that if I died and there was a board running things, the money might start going to causes I wasn’t interested in funding.”
On Friday, the Beldon Fund closed its doors, having spent about $120 million over a decade strengthening environmental organizations in five states — Florida, Michigan, Minnesota, North Carolina and Wisconsin — and increasing awareness of the impact that environmental degradation has on human health.

Downtown Minneapolis Trash Burn to Increase 20 Percent
Just in time for the return of outdoor baseball to Minnesota, the downtown garbage burner is planning to expand next door to the new ballpark.
A proposal making its way through Minneapolis City Hall would allow the Hennepin Energy Recovery Center to burn as much as 20 percent more trash — about 200 tons more per day — the first expansion since the burner was built in 1989. The change would occur next summer when the Minnesota Twins would be playing their first season at Target Field.
Opposition so far is limited to environmental activist Leslie Davis, who unsuccessfully sued to block construction of the stadium until the environmental impact of its location was studied. Twins and ballpark officials support the burner plans.
Minnesota to receive $107 million for Clean Water Fund
Sen. Amy Klobuchar announced that Minnesota will receive more than $107 million in funding for the state’s Clean Water State Revolving Fund program.
The money will also come, in part, from the Drinking Water State Revolving Fund that comes from the American Recovery and Reinvestment Act. These funds will help jumpstart the economy and create jobs, while improving water quality.
“I believe the first responsibility of government is to ensure the safety of its citizens, and making sure people have clean water to drink is an important part of that,” said Klobuchar.
Funding granted for shoreline stabilization project
A grant received by the East Otter Tail Soil and Water Conservation District (EOTSWCD) will go toward shoreline stabilization projects.
The funding was granted by the Minnesota Board of Water and Soil Resources to pay for services provided by a Minnesota Conservation Corps (MCC) crew. The funding was available through the Clean Water Legacy program to assist with projects that help protect and restore water quality.

Well water could cause health problems in children
Private well water should be tested yearly, and in some cases more often, according to new guidance offered by the American Academy of Pediatrics.
The recommendations call for annual well testing, especially for nitrate and microorganisms such as coliform bacteria, which can indicate that sewage has contaminated the well. The recommendations point out circumstances when additional testing should occur, including testing when there is a new infant in the house or if the well is subjected to structural damage.
Shoreview tests permeable paving
Shoreview is betting on a new “green” concrete paving method that lets rainwater pass right through the street surface to prevent damaging runoff.
Pervious concrete — made of gravel and cement minus the sand that gives regular concrete its impenetrable density — has the porous quality of a Rice Krispies bar.
Because it will allow water to drain straight to the ground below, Shoreview will install about a mile of pervious concrete streets without storm sewers in the Woodbridge neighborhood on Lake Owasso.

Wisconsin volunteers document life in holding ponds
Jody Barbeau wades into a shallow pond in woods less than a mile from shoppers at Mayfair Mall and commuters on congested U.S. Highway 45 – to glimpse a bustling community of other creatures.
Two mallard ducks cautiously paddle away from Barbeau, but there is no indication of aquatic life until he lifts a net out of the water.
Reddish dots on the fabric are water mites, he said.
A nearly transparent crustacean with a bulbous head is a male fairy shrimp, a relative of the lobster, said Barbeau, a biologist and volunteer pond monitor. They float belly up.
An explosion of fairy shrimp in late April and early May clogged the

Maryland goats invasives to save turtles
A herd of goats coming to the rescue of a handful of imperiled turtles may sound like the plot of a Saturday morning children’s cartoon show, but that’s just what’s happening in the Carroll County town of Hampstead.
The State Highway Administration has enlisted the help of about 40 goats to devour invasive plant species in wetlands along the path of the soon-to-open, 4.4-mile Hampstead Bypass to protect the habitat of the bog turtle – a species listed as threatened in Maryland.
State highway officials decided to give the goats a tryout as four-legged lawn mowers rather than to attack the unwanted vegetation with mechanical mowers that might have killed the diminutive reptiles or damaged their boggy habitat on the fringe of Hampstead. The goats – leased from a local farmer who prefers to remain anonymous – have been on the job for a week, and highway officials say that so far they seem to be up to the task.

Research: Environmental estrogens impact male rats
A five-generation rat study provides the clearest evidence to date that exposure to low levels of environmental estrogens can increase the risk of abnormal cell growth in the male breast. Abnormalities which could have the potential to become cancerous developed in the mammary gland tissue of male rats that were exposed to either the soy-based phytoestrogen genistein or ethinyl estradiol – an estrogen used in birth control pills. The findings support a growing concern that exposure to low levels of estrogen in the environment might increase the risk of breast cancer.

Legislation limits DNR oversight of Mississippi
Cities and homeowners who feared new rules would reduce their control over property and development are welcoming changes made in the critical-river-area measure signed by the governor.
Legislators said the bill, included in the Legacy Amendment law, was modified to protect homeowners and cities along a 72-mile stretch of the Mississippi River, from Hastings to Dayton.
The measure allocated $500,000 over two years for the state Department of Natural Resources (DNR) to revise rules for new development along the corridor. The DNR is to begin developing rules in January.

Australian desalination plant under way
Sydney’s controversial desalination plant is almost 80 per cent complete and will start pumping drinking water this summer, the New South Wales government says.
NSW Water Minister Phillip Costa says the plant, at Kurnell is Sydney’s south, will be able to provide 15 per cent of the city’s water within five years.
“It’s well and truly advanced, 70 to 80 per cent complete. Commissioning will occur by the end of the year,” he told a Sydney conference on NSW’s urban water sustainability. “We’re looking at water coming online in the summer 09-10. Once operational the plant will be capable of producing 250 million litres of water a day.”
Northeastern U.S. could face rising seas
In the debate over global warming, one thing is clear: as the planet gets warmer, sea levels will rise. But how much, where and how soon? Those questions are notoriously hard to answer.
Scientists at the National Center for Atmospheric Research, in Boulder, Colo., are now adding to the complexity with a new prediction. If the melting of Greenland’s ice sheets continues to accelerate, they say, sea levels will rise even more in the northeastern United States and Maritime Canada than in other areas around the world.
