Estrogen linked to fish kills, study suggests
Exposure to estrogen puts fish at greater risk of disease and premature death, according to a new federal study.

The U.S. Geological Survey study showed that estrogen exposure reduces a fish’s ability to produce proteins that help it ward off disease and pointed to a possible link between the occurrence of intersex fish and recent fish kills in the Potomac and Shenandoah rivers.

The report, published in the current issue of Fish & Shellfish Immunology, adds to a growing body of research pointing to problems with estrogen in the nation’s waterways.

DNR investigates reported fishkill
A reported die-off of sturgeon in the Mississippi River south of Prescott, Wis., prompted an inconclusive search by Minnesota Department of Natural Resources fisheries staff.

DNR area fisheries supervisor Kevin Stauffer said a three-hour search by fisheries staff didn’t reveal any dead sturgeon in Pool 3, the stretch of river between Hastings and Red Wing.

Anglers reported the fishkill to the DNR, saying they had seen dead fish last weekend and the previous week.

Greg Schorn of Newport said he and another angler had seen 50 to 100 dead sturgeon, as well as several other dead species, while they were fishing Pool 3.

Oil slick covers 80 miles of Mississippi River
Crews continued to work overnight Wednesday to corral a huge oil spill on the Mississippi River that now stretches more than 80 miles below New Orleans and threatens the fragile delta ecosystem. Government officials, meanwhile, are scrambling to bolster water supplies downriver from the spill and some anticipate possibly having to truck in water.

More than 400,000 gallons of thick industrial fuel oil spilled just upriver from the Crescent City Connection in the collision early Wednesday morning between a tanker and a barge being pulled by a tugboat. The oil spill, the largest on the Mississippi River in the New Orleans area in nearly a decade, halted shipping traffic on one of the nation’s busiest waterways.

The Coast Guard, which is investigating the incident, has released few details, but confirmed that none of the tugboat’s crew had the proper licenses to operate on the river. Neither the tug operator’s name nor the name of the river pilot aboard the tanker has been released.

Vermont cows do their thing to curb global warming
Chewing her cud on a recent sunny morning, Libby, a 1,400-pound Holstein, paused to do her part in the battle against global warming, emitting a fragrant burp.

Libby, age 6, and the 74 other dairy cows on Guy Choiniere’s farm here are at the heart of an experiment to determine whether a change in diet will help them belch less methane, a potent heat-trapping gas that has been linked to climate change.

Since January, cows at 15 farms across Vermont have had their grain feed adjusted to include more plants like alfalfa and flaxseed — substances that, unlike corn or soy, mimic the spring grasses that the animals evolved long ago to eat.

New mining development in northern Minnesota poses environmental risk
The fears about copper-nickel mining start with sulfuric rock the metals are found in. When exposed to the air, these rocks can leech caustic pollutants like acid and metals.

Just west of Duluth, the St. Louis River spills through rocky channels on a final plunge to Lake Superior. Retired biology teacher Len Anderson said, not only is this area beautiful, it’s key for the Lake Superior fishery.

“It also is the nursery for many of the fish that inhabit Lake Superior,” Anderson said. “You know, over 100 river miles away from PolyMet, but this is where, I believe, the critical issue is going to come to a head.”

The issue, he said, is methyl mercury – mercury in a form that can harm fish as well as the people and animals that eat the fish.

L.A. restricts lawn sprinkling to two days a week
It’s now illegal to water lawns in the nation’s second-largest city except on Mondays and Thursdays as Southern California deals with the effects of drought and regulatory restrictions on its distant water supplies.

The city is facing its third consecutive year of water supply shortages, according to the city Department of Water and Power, and the new sprinkler ordinance is accompanied by a pocketbook incentive for conservation.

The amount of water customers can purchase at the lowest price, known as Tier 1, will now be reduced by 15 percent. Customers who do not achieve a 15 percent reduction in usage will be charged at a higher rate for every gallon above their Tier 1 allotment.

A rooftop garden grows in Milwaukee
A year ago, Erik Lindberg rented a boom lift with a bucket and hoisted 15 cubic yards of dirt to the roof of his north side remodeling business. In the process, he planted himself firmly in the middle of a growing urban agriculture movement.

Lindberg, owner of Community Building & Restoration, turned to rooftop gardening in the belief that his actions might encourage people to grow their own food or buy locally grown produce.

And by selling the vegetables he grows to subscribers and a nearby Outpost Natural Foods store, he may have become Milwaukee’s first commercial rooftop farmer.

“It’s an experiment,” said Lindberg, 42. “Can you develop a business plan out of something like this? The answer is, I don’t know yet.”

Three-quarters of Texas county homes at risk from climate change
A new study suggests more than 100,000 households will be displaced and more than $12 billion infrastructure losses suffered as a result of climate change raising the sea level in the Galveston area over the next 100 years.

The finding comes three days after a Texas A&M University study found that Corpus Christi’s infrastructure will also be affected by climate change.

“The Socio-Economic Impact of Sea Level Rise in the Galveston Bay Region,” commissioned by the Environmental Defense Fund and the British Consulate-General Houston, estimates that 78 percent of households will be displaced in Galveston County. A more aggressive sea level rise could displace 93 percent of households, according to the study.

Federal charges filed in Louisiana wastewater case
Louisiana Land and Water Co. owner Jeff Pruett was arrested by federal marshals after being indicted on 17 felony counts of violating federal pollution laws.

Pruett is president and chief executive officer of Louisiana Land & Water Co., the principal officer of LWC Management Co. and operates more than 30 water and wastewater treatment systems in northeastern Louisiana.

The charges involve violations of the Federal Water Pollution Control Act — commonly referred to as the Clean Water Act — at more than a half-dozen of the systems owned or operated by Pruett.

Invasive species legislation runs into a roadblock: pet owners
Water managers dispatched two experts to Washington recently to back a bill targeting an Everglades problem that seems to get bigger every year. The latest, largest evidence emerged in mid-May: a Burmese python stretching 16½ feet.

It is the longest yet of hundreds, perhaps thousands, of the exotic constrictors the South Florida Water Management District has pulled off its lands and levees in the past few years. More sobering: The female was pregnant, carrying a clutch of 59 eggs — more proof the giant snakes are breeding in the wild.

“These are not little snakes running around. These are massive, dangerous animals,” said district spokesman Randy Smith.

U.S. restricts California water use to protect salmon
Federal regulators levied sweeping new rules on Delta water deliveries to prevent the thirst of California’s farms and cities from rendering extinct several salmon runs, steelhead, green sturgeon and a Pacific Northwest population of killer whales.

The suite of regulations would ensure more cold water is available for spawning fish, and that water operators make it easier for fish to swim from upstream spawning grounds through San Francisco Bay and back again.

The National Marine Fisheries Service estimated the new regulations would cut water supplies from the Delta beginning next year by about 5 percent to 7 percent, or roughly 330,000 acre-feet a year, enough water for a city of about 2 million people. Most of the water loss is due to measures to help steelhead migrate down the San Joaquin River, officials said.

The hit to Delta water supplies comes on top of rules put in place in December to prevent Delta pumps from driving another fish, Delta smelt, to extinction.

Lawmakers seek restrictions on oil drilling tactic
U.S. lawmakers expect to introduce legislation that would reverse a Bush era law exempting a controversial drilling practice from federal oversight, possibly driving up costs and curtailing the development of vast amounts of unconventional energy.

Democratic Representatives Diana DeGette of Colorado and Maurice Hinchey of New York plan a bill that would repeal a measure in a 2005 law that excluded the method of hydraulic fracturing from regulation under the Safe Drinking Water Act.

“This is a very serious issue. If it is not addressed, large numbers of people are very likely to suffer,” Hinchey told Reuters. “Their water will be contaminated. Their houses will no longer be livable.”

Hydraulic fracturing, or “fracking,” injects a mixture of water, sand and chemicals into rock formations at high pressure to force out oil and natural gas. The practice is used to stimulate production in old wells, but is now also used to tap oil and gas trapped in shale beds across North America.

Wisconsin ballast water rules delayed
Wisconsin DNR Secretary Matt Frank says shipping industry concerns about technology are holding up a state plan to make oceangoing Great Lakes ships clean-up their ballast water.

Fishing groups and environmentalists are urging the DNR to finish work on a proposed permit plan aimed at stopping ships with contaminated ballast water from using Wisconsin ports. The Great Lakes ships that come from other nations are thought to bring in invasive species.  Frank says his agency still plans to move ahead with the  permit. But he says some shipping companies say the clean-up technology isn’t quite ready.

Frank says he’s pleased that New York’s ballast water rules were recently upheld, but adds the best thing would be if the federal government passed tougher ballast water requirements. He says the DNR will make a decision sometime this year.

China reports water pollution reduction
China cut its water pollution and emissions of acid rain-causing sulphur dioxide last year as it stepped up efforts to make its economic growth cleaner, state media said.

Chemical Oxygen Demand (COD), a measure of water pollution, dropped by 4.42 percent in 2008 from a year earlier, while sulphur dioxide emissions were down 5.95 percent, the official Xinhua news agency said.

China has promised to cut the two key pollution measures by 10 percent between 2006 and 2010, and is also looking to reduce its energy intensity, or the amount of energy used to create each unit of gross domestic product.

Vacant homes pose mosquito risk
Neglected and foreclosed, abandoned homes add one more obstacle to control mosquitoes, said Clark County Health Department official Doug Bentfield.



Though numbers are sporadic, the number of abandoned properties that need to be sprayed with chemicals to kill the bug’s larvae have increased, he said.



“This is costing the county money,” Bentfield said.



Most problems arise when owners leave items that collect water outside such as pools, bird baths and old tires. Even the children’s pools become a breeding ground for the mosquitoes if neglected.

IBM researching better arsenic filter
Many people in the world lack access to clean drinking water. In places including Bangladesh, millions must drink water containing arsenic, which can cause neurological problems, organ failure, and death. Making robust water filters that can remove salt and arsenic without requiring a lot of energy has been a challenge. Researchers at IBM are developing a material used to make computer chips for more-efficient removal of salt and toxic chemicals from drinking water.

Polymer-membrane water filters have been in use since the 1970s “with no big materials innovation in a long time,” says Robert Allen, senior manager of chemistry at IBM’s Almaden Research Center, in San Jose, CA. There are problems with traditional membrane filters. The chlorine used to kill pathogens in water degrades them. They’re susceptible to fouling, or clogging up, when the water forced through them in a desalination process called reverse osmosis contains oil or proteins.

The IBM researchers have made a new membrane material that resists these problems while also screening out arsenic.

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.”

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.

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.

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.

UM studies remote sensors for water quality
Measuring water quality in lakes and streams traditionally starts with a time-consuming trip with a bucket to get a water sample for the laboratory.

Now University of Minnesota water researchers have found a way to skip that step.

In an ongoing study of urban creeks and watersheds that is focusing this summer on Lake Pamela in Edina, the university is taking thousands of water-quality readings a day using underwater sensors that relay the data by cell phone to the U’s St. Anthony Falls Laboratory.

The study promises to “move environmental monitoring to the next level and improve our understanding and management of water resources,” said Deb Swackhamer, co-director of the university’s Water Resources Center.

N. Mankato says ‘no’ to paying for aquifer study
North Mankato is the lone holdout in a Department of Natural Resources plan to have the seven largest users of an area aquifer split the costs of a study to see if it’s being depleted.

The study’s cost was about $20,000 in 2008, and it may rise.

“The costs are a little unpredictable,” said Shannon Fisher, who is a mediator for the project on behalf of the Minnesota River Board and the aquifer’s users.

The open-ended price of the study is one of the reasons North Mankato chose not to sign the agreement, City Administrator Wendell Sande said.

Wireless sensors save water on golf courses
In seven years of overseeing every root and blade of grass on the grounds at the Merion Golf Club in Ardmore, Pa., Matt Shaffer has built a reputation on innovation and conservation. An early advocate of course playability over aesthetics, he long lived by the maxim “the drier, the better.”

But when a stifling heat wave threatened the club’s greens before the 2005 United States Amateur Championship — a record 17th U.S.G.A. championship at Merion — Shaffer turned to his old boss, Paul R. Latshaw Sr., for advice. Latshaw told him there was one way he could continue to cut down water use while keeping his turf dry and as fast as a microwave: sensors.

Wisconsin utilities question water fee
A municipal water utilities lobbying group is raising concerns about new fees the governor is proposing to fund staff to oversee the implementation of the Great Lakes water compact.

A provision in Gov. Jim Doyle’s proposed budget calls for the Department of Natural Resources to design new fees to impose on power companies, public water utilities and other major water users in the Great Lakes basin.

The intent is to create a fee structure that would raise the estimated $1 million needed annually to run the compact oversight and implementation program, said Eric Ebersberger, water section chief in the DNR’s Bureau of Drinking Water and Ground Water.

But a lobbying group for public utilities is urging the state Legislature to set the fees by statute so any increase would have to be subsequently approved by lawmakers.

Stimulus funds to rebuild Red Wing dam
The lock and dam on the Mississippi River near Red Wing, Minn., the site of more than 100 barge accidents because of the hazardous current, will undergo $70 million in safety improvements over the next two years under the nation’s economic stimulus program, according to the Army Corps of Engineers.

It is one of the Corps’ largest projects under the program, although a long-standing conflict with the Wisconsin Department of Natural Resources (DNR) over the lack of a fish passage threatens to block some of the work.

Critics led by the Wisconsin DNR also object to the Corps’ plans to cut down trees used by perching bald eagles and to embed concrete blocks along vast stretches of shore and bottom land on the Wisconsin side of the river.

Chemical companies win groundwater case
After five months of trial in San Francisco Superior Court, a jury cleared a handful of chemical companies of nearly all the claims brought against them by the city of Modesto, Calif., in the latest phase of a decade-old groundwater pollution case.

The jury did award Modesto about $18.3 million in damages to cover cleanup costs, but that amount could be nullified by settlements the city has already reached with other defendants.

The jury also decided that the remaining defendants, including the Dow Chemical Co., did not act with malice when they manufactured and distributed chemicals, such as perchloroethylene, to dry cleaners in Modesto. That rules out punitive damages, which could have been much larger.

Bottled water deposit bill challenged
A coalition of bottled water companies filed suit to block an expanded bottle deposit law scheduled to take effect next month, arguing that the law, which imposes a deposit fee on bottled water sold in New York State, is unconstitutional.

The coalition includes Nestle Waters North America, the International Bottled Water Association, and industry trade group, and Keeper Springs, a small bottler owned by Robert F. Kennedy Jr., and environmental advocate.

The new law requires distributors to collect a 5-cent deposit per bottle of water, which can in turn be redeemed by consumers, provisions designed to encourage New Yorkers to recycle the billions of water bottles now thrown away each year. But companies that bottle water must affix a new universal product code label to bottles sold in New York.

DNR begins campaign against invasives
Memorial Day weekend, Minnesota Department of Natural Resources conservation officers joined forces with other law enforcement agencies to prevent the transportation of aquatic invasive species from the Brainerd, Lake Mille Lacs and Prior Lake areas.

The increasing zebra mussel populations at Lake Mille Lacs and Rice Lake near Brainerd, and the new zebra mussel infestation at Prior Lake in Scott County are a particular concern.

Minnesota’s water resources are threatened by numerous aquatic invasive species such as the zebra mussels, Eurasian watermilfoil and purple loosestrife. These species could be easily spread within the state if citizens, businesses and visitors don’t take the necessary steps to contain them.

The DNR offered these suggestions:

Drain bait buckets, bilges and live wells before leaving any water access.

  • Remove aquatic plants from boats and trailers to prevent the spread of invasive species. The law requires it.
  • Drain all water from your boat when leaving waters that have been designated as infested with spiny water flea or zebra mussels.

The coordinated enforcement effort will include an increased presence at public water accesses, where officers will look closely for violators who could face fines of up to $500.

EPA designates greenhouse gases as pollutants
The Environmental Protection Agency formally declared carbon dioxide and five other heat-trapping gases to be pollutants that endanger public health and welfare, setting in motion a process that will lead to the regulation of the gases for the first time in the United States.

The E.P.A. said the science supporting the proposed endangerment finding was “compelling and overwhelming.” The ruling initiates a 60-day comment period before any proposals for regulations governing emissions of heat-trapping gases are published.

Lake Vermilion state park in jeopardy
In 2007, Gov. Tim Pawlenty announced his initiative to buy 2,500 acres of land along Lake Vermilion in northeastern Minnesota. At the time, he said securing the land would make the park one of the nicest parks in the nation.

“We hope through this proposal that we’ll be able to give everyone in Minnesota and up at the lake or up north experience through this next state park,” Pawlenty said.

Pawlenty expressed confidence that the state would purchase the land from owner U.S. Steel, saying at one point that the deal won’t fall apart.

But now, Pawlenty appears to have all but given up on the park.

EPA demands endocrine tests on pesticides
The Environmental Protection Agency for the first time will require pesticide manufacturers to test 67 chemicals contained in their products to determine whether they disrupt the endocrine system, which regulates animals’ and humans’ growth, metabolism and reproduction, the agency said.

Researchers have raised concerns that chemicals released into the environment interfere with animals’ hormone systems, citing problems such as male fish in the Potomac River that are bearing eggs. Known as endocrine disruptors, the chemicals may affect the hormones that humans and animals produce or secrete.

UM report documents ethanol’s water use
While recycling and other advancements have reduced water use in Minnesota’s corn-ethanol plants by a third of the levels of just a few years ago, increased reliance on irrigated corn has pushed water consumption to alarming levels in the desert Southwest and parts of California.

A University of Minnesota report notes that Minnesota’s 17 ethanol plants currently average about 3.5 gallons of water for each gallon of ethanol produced. This is down from about 10 gallons per gallon of ethanol just a decade earlier.

However, over-all water consumption rates rise quickly when ethanol is produced from corn that is irrigated, as it is on 207,000 acres in Minnesota or 3 percent of the state’s 7.8 million acres planted to corn.

Los Angeles raises water rates to spur conservation
Los Angeles businesses, landlords and residents will pay more for water starting June 1 if they don’t cut back at least 15 percent on usage under a plan approved by the Los Angeles City Council.

The Los Angeles Department of Water & Power plan is aimed at sending water customers price incentives to encourage conservation.

The region is in the midst of a three-year drought, exacerbated by dwindling water allocations from the DWP’s Owens Valley aqueduct, the State Water Project and the Colorado River. The Metropolitan Water District of Southern California, the region’s wholesale water supplier, announced it was cutting its allocations by about 10 percent, effective July 1.

China faces water crisis
Over the past year getting clean water has been a struggle for many in China. In February one of the most severe droughts to hit China in a half-century affected some 5 million people and 2.5 million livestock in the provinces of Hebei and Henan, near Beijing. Farther south in Yancheng, Jiangsu, 300 kilometers from Shanghai, more than 200,000 people were cut off from clean water for three days when a chemical factory dumped carbolic acid into a river. Just before the Olympics last June, the coastal city of Qingdao, site of the sailing events, saw an explosion of algae in nearby waters that may have been caused by pollution.

High Plains Aquifer down 9% since pumping began
The High Plains Aquifer, the sea of fresh water under the Great Plains, is about 9 percent smaller since irrigators and cities started tapping it in about 1950, according to a new report.

The total amount of drainable water in the aquifer in 2007 was about 2.9 billion acre-feet, a decline of about 270 million acre-feet since before development, the U.S. Geological Survey said in a report .

An acre-foot of water is equivalent to the volume of water that would cover one acre to a depth of 1 foot.

Florida suit seeks to force EPA water quality review
An environmental group has filed a lawsuit accusing the Environmental Protection Agency of letting Florida flout federal clean water requirements.

Linda Young, director of the Clean Water Network of Florida, said Monday the group is seeking a court order for EPA to conduct an independent review of a state list of water bodies and decide which ones need stricter pollution limits.

Ag groups seek to overturn pesticide ruling
Twenty-two agricultural organizations asked that the full Sixth Circuit Court of Appeals rehear a landmark pesticide case, even as the Environmental Protection Agency, a party to the case, declined to do so. A January opinion on National Cotton Council of America v U.S. Environmental Protection Agency from a three-judge panel was the first U.S. court ruling that pesticide discharge is a point source of pollution subject to additional regulation and permitting under the Clean Water Act (CWA).

The agriculture groups submitted their request in a friend of the court brief, arguing the decision ignored the definition in CWA of “point source” and that point sources are regulated only where they convey pollutants to navigable waters, not where they convey things that may at some later point result in water pollution.

Pollution concerns, frog calls and smuggled dish soap

March 30, 2009

Drinking water pollution tops concerns, poll shows
Pollution of drinking water is Americans’ No. 1 environmental concern, with 59% saying they worry “a great deal” about the issue, according to a new Gallup Poll.

All eight environmental issues tested in the 2009 Gallup Environment survey, conducted March 5-8, appear to be important to Americans, evidenced by the finding that a majority of Americans say they worry at least a fair amount about each one. However, on the basis of substantial concern — that is, the percentage worrying “a great deal” about each — there are important distinctions among them.

Four water-related issues on the poll fill the top spots in this year’s ranking. In addition to worrying about pollution of drinking water, roughly half of Americans also express a high degree of worry about pollution of rivers, lakes, and reservoirs (52% worry a great deal about this), and water and soil contamination from toxic waste (52%). About half worry about the maintenance of the nation’s supply of fresh water for household needs (49%).

EPA finding pushes Obama on climate change
The Environmental Protection Agency’s new leadership, in a step toward confronting global warming, submitted a finding that will force the White House to decide whether to limit greenhouse gas emissions under the nearly 40-year-old Clean Air Act.

Under that law, EPA’s conclusion — that such emissions are pollutants that endanger the public’s health and welfare — could trigger a broad regulatory process affecting much of the U.S. economy as well as the nation’s future environmental trajectory. The agency’s finding, which was sent to the White House Office of Management and Budget without fanfare, also reversed one of the Bush administration’s landmark decisions on climate change, and it indicated anew that President Obama’s appointees will push to address the issue of warming despite the potential political costs.

Human drugs found in fish near treatment plants
Fish caught near wastewater treatment plants serving five major U.S. cities had residues of pharmaceuticals in them, including medicines used to treat high cholesterol, allergies, high blood pressure, bipolar disorder and depression, researchers reported.

Findings from this first nationwide study of human drugs in fish tissue have prompted the Environmental Protection Agency to significantly expand similar ongoing research to more than 150 different locations.

Listen for some croaks, help with some research
The Minnesota Department of Natural Resources’ Nongame Wildlife Program is recruiting volunteers to participate in its ongoing statewide frog and toad calling survey.

Since 1996, volunteers have collected data by listening to and identifying frog and toad species on specified 10-stop routes. The results provide information on where species are located and how their populations change in abundance and distribution.

Spokane phosphate ban sparks dishwasher revolt
The quest for squeaky-clean dishes has turned some law-abiding people in Spokane into dishwater-detergent smugglers.

They are bringing Cascade or Electrasol in from out of state because the eco-friendly varieties required under Washington state law don’t work as well.

Water issues now part of power-generating calculus
Last month, Tri-State Generation and Transmission Association, a utility that provides power to mostly rural areas, agreed to conduct a major study to see if it might meet growing energy needs through energy efficiency and not a big, new coal-fired power plant, as it had proposed for southeast Colorado.

One reason for the move was a challenge by Environment Colorado, an advocacy organization, about the amount of water a new plant would require.

Firm plans trash-to-diesel plant in Rosemount
Plans for a plant outside Rosemount that would turn trash into diesel fuel are moving along, despite early concerns from nearby cities.

The Empire Township Board approved a zoning change and comprehensive plan amendment Tuesday that will allow Rational Energies LLC to build a 200,000 square-foot biomass gasification facility on about 50 acres at the intersection of Hwy. 52 and County Road 46.

Great Lakes ice cover diminishing over time
Ice cover on the Great Lakes has declined more than 30 percent since the 1970s, leaving the world’s largest system of freshwater lakes open to evaporation and lower water levels, according to scientists associated with the National Oceanic and Atmospheric Administration.

They’re concerned about how the milder winter freeze may affect the environment. But they’re also trying to come to terms with a contradiction: The same climate factors that might keep lake ice from freezing might make freezing more likely if lake levels drop due to evaporation.

Big wilderness bill passes Congress
Congress set aside more than 2 million acres in nine states as protected wilderness — from California’s Sierra Nevada mountains to the Jefferson National Forest in Virginia.

The legislation is on its way to President Barack Obama for his likely signature.

The House approved the bill, 285-140, the final step in a long legislative road that began last year.

EPA reverses stand on mountaintop mining
In a sharp reversal of Bush administration policies, the head of the Environmental Protection Agency said the agency planned an aggressive review of permit requests for mountaintop coal mining, citing serious concerns about potential harm to water quality.

The administrator, Lisa P. Jackson, said her agency had sent two letters to the Army Corps of Engineers in which it expressed concern about two proposed mining operations in West Virginia and Kentucky involving mountaintop removal, a form of strip mining that blasts the tops off mountains and dumps leftover rock in valleys, burying streams.

Ethanol industry faces scrutiny on feed byproduct
The ethanol industry must be wondering where the bottom is. Profits are slim or non-existent and about 20 percent of all U.S. plants are shut down. In addition, ethanol’s main by-product, which is sold as livestock feed, has raised potential food safety concerns. Several studies have linked the by-product known as distillers grain to elevated rates of E. coli in cattle. And now, distillers grain is facing further scrutiny because the Food and Drug Administration has found that it often contains antibiotics leftover from making ethanol.

Water a new cash crop for California farmers
As Don Bransford prepares for his spring planting season, he is debating which is worth more: the rice he grows on his 700-acre farm north of Sacramento, or the water he uses to cultivate it.

After three years of drought in California, water is now a potential cash crop. Last fall, the state activated its Drought Water Bank program for the first time since 1994. Under the program, farmers can choose to sell some of the water they would usually use to grow their crops to parched cities, counties and agriculture districts.

Las Vegas water pipeline opposed
A coalition of ranchers, farmers and conservationists is turning up the volume on efforts to block a plan to pipe billions of gallons of groundwater a year from the northeast part of Nevada to Las Vegas.

A coalition lawyer says State Engineer Tracy Taylor relied on bad data and flawed reasoning in deciding last July to let the Southern Nevada Water Authority pump some 6.1 billion gallons of water a year from the rural Cave, Dry Lake and Delamar valleys.

Snail evolves larger shells to fight invasive crab
With all the recent changes in the oceans, like dying coral reefs and collapsing commercial fisheries, it’s easy to forget that most changes occur over the longer term. Sometimes the incremental changes are so slight that they aren’t noticeable for decades.

A case in point is described in The Proceedings of the National Academy of Sciences by Jonathan A. D. Fisher of Queen’s University in Ontario, Peter S. Petraitis of the University of Pennsylvania and colleagues: They report on a large size increase in the shells of a well-studied intertidal snail, the Atlantic dogwinkle (Nucella lapillus), around Mount Desert Island in Maine over the last century.

USDA gardening zones to reflect climate change
As winter retreats northward across the nation, gardeners are cleaning tools and turning attention to spring planting. But climate change is adding a new wrinkle, and now a standard reference – the U.S. Department of Agriculture’s Plant Hardiness Zone Map – is about to make very clear how much rising temperatures have shifted planting zones northward.

The guide, last updated in 1990, shows where various species can be expected to thrive.  A revision is expected sometime this year, and while the agency hasn’t released details, horticulturalists and experts who have helped with the revision expect the new map to extend plants’ northern ranges and paint a sharp picture of the continent’s gradual warming over the past few decades.

USGS studies endocrine-disruptors in Chesapeake Bay
Fish health and reproductive issues in the Chesapeake Bay drainage may be associated with fish exposure to hormone-mimicking compounds and other chemicals.

U.S. Geological Survey scientists have studied yellow perch, a species that has declined in recent years, and found that differences in the egg quality of these fish is occurring in some sites they sampled.  In addition, scientists sampled smallmouth bass and other species from major fish kills in the South Branch of the Potomac and the Shenandoah River. They found the fish were infected with a variety of types of skin lesions and a number of disease-causing bacteria, viruses and parasites.

Volunteers sought for phenology survey
Volunteers across the nation are being recruited to get outdoors and help track the effects of climate on seasonal changes in plant and animal behavior.

The USA-National Phenology Network (USA-NPN), a consortium of government, academic and citizen-scientists, is launching a new national program built on volunteer observations of flowering, fruiting and other seasonal events. Scientists and resource managers will use these observations to track effects of climate change on the Earth’s life-support systems.

“This program is designed for people interested in participating in climate change science, not just reading about it,” said USA-NPN Executive Director and U.S. Geological Survey scientist Jake Weltzin. “We encourage everyone to visit the USA National Phenology Network Web site and then go outside and observe the marvelous cycles of plant and animal life.”

U.S. to revise policy on lynx habitat
Soon some immigrants will find life easier in Minnesota and the rest of the United States: A proposed change in the management of land roamed by the Canada lynx would broaden protections for the big cat.

The U.S. Fish and Wildlife Service revised its critical habitat designation for the lynx, which has been the subject of controversy and court actions in the last few years. The proposal preceded an announcement Tuesday by President Obama to resume full scientific reviews of projects that might harm endangered wildlife and plants.

EPA plans new rules on coal ash retention ponds
The Obama administration will propose new regulations governing coal combustion waste by the end of the year, and will act immediately to prevent accidents like the release in December of more than a billion gallons of coal ash that smothered 300 acres in eastern Tennessee and choked nearby waterways, a senior Environmental Protection Agency official said.

The spill, at the Kingston Fossil Plant operated by the Tennessee Valley Authority near Knoxville, brought renewed attention to the agency’s failure to live up to a promise in 2000 to issue regulations for coal ash, which contains toxins like arsenic, lead and mercury.

Grassroots Japanese protest opposes river dam
First, the farmers objected to an ambitious dam project proposed by the government, saying they did not need irrigation water from the reservoir. Then the commercial fishermen complained that fish would disappear if the Kawabe River’s twisting torrents were blocked. Environmentalists worried about losing the river’s scenic gorges. Soon, half of this city’s 34,000 residents had signed a petition opposing the $3.6 billion project.

California farming town prepares for drought Armageddon
Shawn Coburn is barreling down a country road in his white Ford F-150 pickup, talking about how California’s water crisis darkly reminds him of a scene from a movie aptly named “Armageddon.”

“Billy Bob Thornton tells Bruce Willis that a huge asteroid is approaching Earth,” says Coburn, 40. “Willis asks Thornton who will get hurt, and Thornton tells him that he just doesn’t get it — that everyone will be dead, that the game is over.”

The disaster coming this spring and summer is no movie, and nothing menacing is falling from the sky.

Sacramento considers selling wastewater
Californians have grown accustomed to digesting odd ideas that routinely flow out of Sacramento, many of them not so palatable.

But are they ready for this one?

Last week, amid a third year of a statewide drought, the Sacramento Regional County Sanitation District adopted a strategy to sell treated sewage as drinking water. The buyer would hypothetically partner with the district to recycle wastewater from the capital-area’s 1.4 million people into a new municipal water source.

Oregon experiments with conservation credits
Three years ago, Oregon looked ready to re-invent conservation banking. Instead of establishing separate banks to offset wetland damage and other habitat loss caused by transportation construction, the Oregon Department of Transportation (ODOT) was going to roll it all into one package.

On this web site Bill Warncke, ODOT’s Mitigation and Conservation Program Coordinator, laid out an innovative approach that would address multiple resources simultaneously – including wetlands, water quality, fish and wildlife habitat, and endangered species.

Just months later, however, the plan was shelved.

Idaho fish farm squeezed out irrigators
The head of the Idaho Department of Water Resources has ordered hundreds of groundwater users in south-central Idaho to stop pumping, saying that a fish farm has first dibs on the limited resource.

The curtailment order came from David Tuthill. It is intended to ensure that Clear Springs Foods, a fish farm near Hagerman, has access to the water it needs to maintain the farm. Idaho law distributes water rights on a first-come, first-served basis, and the fish farm has an older, or senior, water right compared to the 865 junior water rights held by the roughly 430 people affected by the curtailment.

California drought now officially an emergency
Citing a third consecutive year of drought conditions, Gov. Arnold Schwarzenegger Friday declared a state of emergency and called on urban residents to cut their water usage by 20 percent.

The announcement could intensify talks in the Capitol about upgrading the state’s water infrastructure — a contentious debate that has pitted environmentalists who favor conservation against proponents of building new dams to boost supplies. Negotiations in the Legislature have stalled repeatedly in recent years over the issue of dams.

Tap water in a bottle? Don’t laugh. It sells
Two teachers on their lunch break scanned a refrigerated shelf inside a Manhattan coffee shop lined with drink bottles: Naked Juice, Perrier, Smartwater, New York City tap water.

“Tap water?” said Alison Szeli, 26, picking up the clear plastic bottle with orange letters: “Tap’d NY. Purified New York City tap water.”

She studied the description: “No glaciers were harmed in making this water.” She compared prices: Smartwater cost $1.85. Tap’d NY was 35 cents less.

Firms urged to disclose ‘water footprint’
Corporations’ “water footprint” — assessing their water use and pollution — should be disclosed in SEC financial reports along with companies’ strategies for dealing with expected growth in water-related costs, according a report by Ceres and the Pacific Institute.

“Investors also have a significant interest and role” in encouraging companies “to look more closely at their potential risk exposure to water-related challenges,” according to the 60-page report issued today. Investors should be aware of potential financial, regulatory and reputational risks corporations face related to water usage and availability that could drive up costs, the report said.

New type of toilet promises to save water, money
In the industrialized world, most of us (except those who have septic tanks) rely on wastewater-treatment plants to remove our excrement from the drinking-water supply, in great volumes. (Toilets can use up to 30 percent of a household’s water supply.) This paradigm is rarely questioned, and I understand why: flush toilets, sewers and wastewater-treatment plants do a fine job of separating us from our potentially toxic waste, and eliminating cholera and other waterborne diseases. Without them, cities wouldn’t work.

But the paradigm is flawed. For a start, cleaning sewage guzzles energy. Sewage treatment in Britain uses a quarter of the energy generated by the country’s largest coal-fired power station.

Levees in 16 states flunk inspections
More than 100 levees in 16 states flunked maintenance inspections in the last two years and are so neglected that they could fail to stem a major flood, records from the U.S. Army Corps of Engineers show.

The 114 levees received “unacceptable” maintenance ratings in corps inspections, meaning their deficiencies are so severe that it can be “reasonably foreseen” that they will not perform properly in a major flood, according to the records, which were requested by USA TODAY. As a result, the corps is advising state and local levee authorities that the levees no longer qualify for federal rehabilitation aid if damaged by floodwaters.
