Sweet, and Organic

According to Discovery News writer Emily Sohn, "Sweeteners Linger in Groundwater. After tickling the tongue, artificial sweeteners pass through our bodies and end up in wastewater virtually unchanged. Some sweeteners are particularly widespread in the environment, according to a new study, making them ideal markers for following pollution from treatment plants and other sources into the environment. "Groundwater can be polluted by several sources, and it's sometimes not clear where that pollution comes from," said Ignaz Buerge, an environmental chemist at the Swiss Federal Research Station in Schloss. " We now have a marker of domestic wastewater which can be used in tracing pollution." Contaminated groundwater is both an environmental and public health issue. Once run-off gets into the environment, though, it can be hard to know whether it came from industry, agricultural fields, traffic, homes or other sources. Scientists have been looking for marker molecules that might help them track down and possibly reduce some of these inputs. Previous candidates for markers have included caffeine, pharmaceuticals and components of personal care products. Most of these chemicals, however, either break down quickly, appear in quantities too small to easily detect, or seep out of the water and into the soil."

Water, water...such a vital resource, and so abused.

On the other hand, organic is the way to go for jobs. An article in NYT, "Many Summer Internships Are Going Organic" by Kim Severone is worth everyone's attention. Reproduced below.

****Axelrod, who graduated from Barnard College last week with an urban studies degree, will not be fighting over the bathroom with her five roommates on the Upper West Side this summer. Instead she will be living in a tent, using an outdoor composting toilet and harvesting vegetables on an organic farm near Petaluma, Calif.

As the sole intern at a boutique dairy in upstate New York, Gina Runfola, an English and creative writing student, has traded poetry books for sheep.

And Jamie Katz, an English major at Kenyon College in Ohio, is planting peach trees at Holly Tree Farm in Virginia.

These three are part of a new wave of liberal arts students who are heading to farms as interns this summer, in search of both work, even if it might pay next to nothing, and social change.

They come armed with little more than soft hands and dog-eared copies of Michael Pollan’s “The Omnivore’s Dilemma,” which takes a dim view of industrial agriculture.

A few hope to run their own farms. Others plan to work on changing government food policy. Some are just looking for a break from the rigors of academia. But whatever the reason, the interest in summer farm work among college students has never been as high, according to dozens of farmers, university professors and people who coordinate agricultural apprenticeships.

Andrew Marshall, who began organizing apprenticeships for the Maine Organic Farmers and Gardeners Association in 2003, used to see an average of 75 applications a year. This season, he has fielded over 200, with more coming in every day.

Katherine L. Adam, who runs the National Sustainable Agriculture Information Service, financed by the Department of Agriculture, said 1,400 farms sought interns this year, almost triple the number two years ago. The number of small farms, which attract the new agrarians and can use the cheap, enthusiastic help, has grown sharply since 2003, according to the department.

Of course, employing people who know a lot about food systems but nothing about farming can be as much a headache as a help. Manure spreaders get broken, carrot shoots get pulled instead of weeds, and people sleep in. It is not all hayrides and flowers for the apprentices, either. Ms. Adam sometimes gets complaints from interns who say the amenities are not good enough or the farmers work them too hard...."
