Pollution Cuts Could Restore Lake Tahoe Clarity, Study Says

Reducing about 35% of the pollution now entering the water could help restore its historic clarity, the UC Davis report says.

The renowned water clarity in Lake Tahoe can be returned to its historic 100 feet of visibility by cutting pollution by about 35% from runoff, chimney soot, dust and emissions from cars and trucks, according to UC Davis researchers who are conducting a study for state water officials.

Their initial findings, to be announced today by the state’s Lahontan Regional Water Quality Board, are expected to trigger public debate over how to achieve such a significant reduction in the mountain resort community that has at least 3 million visitors a year and already has an array of anti-pollution measures in force.

One regional planning official said the study, which is to be finalized in October, might prompt new efforts to keep sediment from flowing into the lake, expand public transportation, use biomass facilities to burn brush left over from tree thinning and even limit fertilizer used on lawns and athletic fields.


The researchers do not specify how much each type of pollution needs to be reduced, but say they believe that an overall reduction of roughly a third not only would halt the degradation of Tahoe’s cobalt-blue waters but could restore the lake’s historic clarity over several years.

“We are truly charting new territory in our quest to protect a national treasure,” said Harold Singer, executive officer of the Lahontan Regional Water Quality Control Board.

Visibility in the lake was about 100 feet in the 1970s, but had declined to 74 feet by 2004, according to the UC Davis Tahoe Environmental Research Center.

The main culprits are dirt, dust and other fine particles, said Geoffrey Schladow, the center’s director. “There are several pollutants … coming from streams, urban runoff … atmospheric inputs from cars, and car tires kicking up dust. And we have dust input from the Central Valley, the Bay Area and even Mongolia in Asia.”

Schladow said that a reversal could be accomplished by reducing fine sediment, nitrogen and phosphorous from groundwater, stream channel erosion, airborne deposits and runoff from urban areas and the forest. Nitrogen and phosphorus are nutrients that promote algae growth, and fine sediment becomes suspended in water, making it less clear.

The research findings are based on computer modeling, as well as a study of sediment from the lake bottom, which showed that pollution from past activities, such as logging during the mid-1800s, settled out more quickly than previously thought.

Officials said the data would help decision-makers figure out how to accomplish the reduction in pollution, which has been the subject of numerous studies in recent decades.

John Singlaub, executive director of the Tahoe Regional Planning Agency, said: “It’s exciting to have the data that show it’s possible to restore Tahoe’s water clarity to historic levels within our lifetime. We’ll have many tough decisions to make about how to achieve the goal, but to know it’s scientifically possible is a breakthrough.”

Attempts to preserve Tahoe’s clear water have largely involved limiting runoff by reducing construction and traffic and restoring wetlands and waterways to help prevent contaminants from reaching the lake.

The water clarity study is part of a joint California-Nevada effort to establish allowable levels of pollutants to meet water quality standards under the federal Clean Water Act. Officials expect that the study will be useful as they develop long-range plans to preserve the Tahoe Basin’s environment.

The next step in improving the lake’s clarity, Singlaub said, will be to determine where to focus pollution reduction efforts. He said it would make sense to concentrate on the Upper Truckee River watershed, which he said contributes much of the fine sediment in the lake.

But he also said the region needed to discuss stricter controls of nitrogen fertilizers. “We have not put restrictions on individual homeowners and have not looked at artificial turf for athletic fields,” he said.

Reducing nitrogen emissions from cars and boats would be a challenge, Singlaub said. “What it reinforces is the need for a major investment in public transportation in getting people in and out of the basin, and within the basin once they are here.”

Oregon State University professor Robert Collier, who has studied water clarity loss at Crater Lake, said he has not seen the UC Davis analysis but believes that it is on the right track.

“Now whether one could achieve about a 35% reduction with all the people that live in the basin, I do not know,” he said. “It will be a big problem to get a number that is that big. Suspended sediment in general is a difficult one to control.”

Homeless Tent Camps Draw Ire in Paris

By ANGELA DOLAND, Associated Press Writer

(07-25) 11:45 PDT PARIS, France (AP) –

Eric Creuly’s bedroom is a khaki tent on the banks of a Paris canal. His kitchen is a barbecue made from a metal barrel, and his living room is a set of mismatched chairs where he and friends smoke and watch the pleasure boats pass.

Tent camps have become a familiar sight in Paris since the aid group Doctors of the World, or Medecins du Monde, first distributed tents in December to shelter the homeless and make their plight less invisible.

But complaints about the tents have been pouring into City Hall, and four tents were burned this weekend in circumstances that are still unclear. With Paris sweltering in a heat wave, authorities say the tents are unsanitary and dangerous.

Socialist City Hall wants many of them moved, and the conservative government wants them just plain gone. Last week, the government named a mediator to find a solution.

 

About 300 tents with the aid group’s insignia still dot Paris — and they are even harder to overlook in July, when tourists fill the streets and Parisians live outdoors. Now, some homeless are even saving money to buy tents themselves.

Doctors of the World says it will take down one tent for every permanent housing option provided by the government. It acknowledges the risks of tents — that heat-struck homeless could die hidden from view, for example — but adds that street life is dangerous, no matter what.

“We never said that tents were the solution,” said Graciela Robert, who heads the homeless mission for the aid group. “But a tent is better than the sidewalk.”

The tents have popped up under bridges on the Seine River, near the stretch of quay where City Hall sets up a sandy beach every summer. They appeared on chic avenues and on the Canal Saint-Martin, a trendy area for nightlife.

Creuly, a 48-year-old construction worker who became homeless after losing his job a year ago, has spent a few weeks living in his girlfriend’s Doctors of the World tent. It’s better than going to a shelter, he says: He isn’t kicked out during the day and doesn’t have to worry about his belongings being stolen.

He and his friends — some of whom go by nicknames like “Momo the Cat” and “The Indian” — watch out for each other and take turns guarding their row of tents. Tuesday morning, they drank cold coffee and shared croissants under a parasol from an abandoned ice cream cart.

“We’re at home here, we do as we like,” Creuly said. He added, however, that he doesn’t believe the tents will push the government to help the homeless.

France, with a population of nearly 63 million, has about 86,500 homeless people, according to a landmark 2001 study by the INSEE statistics agency. The Abbe Pierre Foundation, which works with the homeless, said this year that the figure is closer to 150,000.

The government fears the tents give people a reason to stay on the streets, expose them to sanitation problems and encourage them to live in groups — a problem because it is harder to persuade them to get help.

“The government’s objective in this affair is simple: no more tents,” said Benoist Apparu, communications official for the Ministry of Social Cohesion. “Not because we don’t like tents, but because the problem with them is that we have enough trouble as it is getting people off the street, persuading them to move to a shelter or a rehabilitation center.”

The Abbe Pierre Foundation shares some of those concerns. Patrick Doutreligne, an official with the Roman Catholic-affiliated charity, said there are as many negative effects as positive ones.

City officials say they don’t disapprove of the tent initiative but want mediators to persuade homeless to move their tents away from apartment buildings, for example.

On Monday, Mayor Bertrand Delanoe sent a letter to the government pressing for 5,000 more homeless lodgings in the Paris region — not just overnight shelters.

Creuly and his friends have dreams of their own. Perched on the edge of the canal, talking about life, they have fantasies about being granted an abandoned building to fix up themselves.

“I realize they can’t just come up with 1,000 new lodgings, just like that,” Creuly said. “But are we supposed to believe anyone is really trying? I’m tired of all this talk.”

New Illinois law lets diners take home leftover wine

This story ran on nwitimes.com on Tuesday, July 25, 2006 12:12 PM CDT

CHICAGO — Wine connoisseurs soon will be able to head home from restaurants with an unfinished bottle of their favorite vintage.

A new state law signed by Gov. Rod Blagojevich on Monday lets restaurant-goers recork and take home leftover wine as long as it is wrapped in a tamperproof bag.

Officials hope it will discourage diners from chugging that last glass of wine, then getting behind the wheel.

Some wine drinkers criticized the measure, though, saying it still might promote driving under the influence.

“Whether it’s corked or not, I am totally against it,” Michelle LeMothe, 46, of Lincoln, said while sipping a glass of chardonnay at a seafood restaurant in downtown Chicago. “I’m in the car with my kids (often) and I don’t want it out there.”

The change takes effect Jan. 1.

Illinois law currently bars people from having open liquor containers in vehicles. But the new law lets them drive with bottles that have been sealed in the specialty bags. That way, if police stop the driver, they’ll be able to see whether the wine has been illegally reopened.

Supporters say people should be able to take home wine just like any other leftover.

“At first blush, it can strike one as a frivolous piece of legislation, but it serves a couple of legitimate purposes,” said Rep. John Fritchey, a Chicago Democrat and the law’s House sponsor.

Restaurants might do more wine business because diners will be more likely to order a bottle — especially an expensive bottle — if they know it won’t go to waste, he said, and road-safety advocates hope people won’t feel obligated to finish off the bottle before going home.

“The legislation is unique because it’s one of those rare bills that is simultaneously pro-business and pro-consumer,” Fritchey said.

Miriam Matasar, manager of Bin 36 in Chicago’s trendy River North neighborhood, said she hopes the new law encourages patrons to try different types of wine. Her restaurant has a 17-page list that offers roughly 50 different wines by the glass and up to 200 by the bottle.

“It’s a great way to play up the bottle list because then people don’t have to feel like they have to drink a whole bottle of wine. They can take it home and enjoy it,” Matasar said.

Most other states already have laws allowing drivers to have opened bottles under certain conditions. Illinois joins 16 other states in requiring the use of special bags for the wine, according to the Web site of a company that makes the bags.

Carrie Young of Chicago washed down her fish tacos with a glass of pinot noir at the downtown seafood restaurant Monday evening. She said the law won’t change her dining habits dramatically.

“You usually go out after dinner and who wants to carry a bottle around?” she said. “And rarely ever do I have any wine leftover, anyway.”
