Raw sewage is apparently a gold mine for virologists in search of new quarry — it contains thousands of previously unknown virus species, according to a new study. Hopefully this unique finding will justify the nasty task of sifting through sewage for science.
Large scale farming is a dirty business, but Taiwan’s environmental authorities have come up with a novel way to clean up it’s six-million-swine pig farming industry: a href="http://green.yahoo.com/news/afp/20110105/od_afp/taiwananimalspollutionfa...">potty train the pork. The Environmental Protection Administration has pledged to increase the number of toilet trained pigs in that country after one breeder successfully reduced the amount of waste water on his 10,000-pig operation by 80 percent by teaching his pigs to use the toilet.
Bacteria have deployed to Afghanistan to help the U.S. Army clean polluted wastewater. The microbes commonly appear in handfuls of dirt, but now form the main component of two new bioreactors made by scientists at Sam Houston State University in Texas.
Desalinization technology has long been trapped between two competing nightmare scenarios. Without desalination, fresh water resources run out and large swaths of the earth suffer crippling water shortages. But if we desalinate on a large scale, we keep burning fossil fuels, the earth warms, the ice caps melt, and sea levels rise to wreak havoc on coastal regions.
Sponge-like substance could help clean up oil spills

It’s no secret that cleaning up an oil spill is a difficult task. When most of us think of oil spills, we think of incidents like the Exxon Valdez accident, which released more than 10 million gallons of oil into the Prince William Sound in 1989. But what we don’t think about are the more than 200 million gallons of used oil that pollute U.S. wastewater every year after being dumped into sewers, streams and landfills.
A parched Los Angeles considers a radical water-conservation plan

Officials in Los Angeles said today that they're going to reconsider a water conservation proposal that won't just ask residents to change their habits, but calls for recycling wastewater, too.
The plan would place restrictions on watering lawns and washing cars, and it would encourage residents to switch to less thirsty washing machines. But the most controversial part of the initiative would involve recycling water - refilling underground drinking supplies with treated wastewater. Los Angeles has tried this before, but critics forced officials to drop it.
Now, though, city officials say improvements in recycling technology make it a viable option.
Sewage is more than just filth. It’s evidence of our worst habits, everything from caffeine to cocaine, all ingested and flushed down the toilet. Now scientists are using wastewater to drug-test entire cities, and the results are sobering

Jörg Rieckermann snaps on a pair of purple rubber gloves, picks up a crowbar, and levers a manhole cover out of the way. “Here’s my access to the underworld,” Rieckermann, who speaks with a faint German accent, says as he hoists up a barrel-shaped robot suspended above a stream of raw sewage.
