air quality

If you own a diesel-powered Volkswagen, you're well aware that this week the German car maker was exposed by federal regulators for equipping vehicles with a computerized “defeat device” that gave inaccurate emissions readings.

The cheat caused nearly a half-million of these diesel models since 2009 to emit low emissions during testing, but then turned off those emissions controls in actual driving situations – allowing the vehicles to get better gas mileage and performance while putting out more pollution.

The study was published in the Proceedings of the National Academy of Sciences by researchers in the United Kingdom, China and the U.S.

Seattle Public Schools is paying $750,000 to settle a lawsuit filed by a teacher who was fired for refusing to work in a building she says made her sick. 

Former teacher Denise Frisino says when she worked at Nathan Hale High School seven years ago, the mold was so bad that she had a hard time breathing and a terrible cough. "It was to the point where I could not be inside the building for long. It was not a minor thing. It was a severe reaction," she says. 

Rob Palmer, whose brother was killed in a wildfire, says the Wildland Firefighter Foundation provides support to families of the fallen.

Dryer than normal conditions prompted Washington Governor Chris Gregoire to declare a state of emergency and extend a ban on outdoor fires. Outdoor burning is banned in all counties until October 15. The state is experiencing a rare stretch of dry weather.
