Summary/DescriptionLake Tahoe Report Segment #57 - "Air Quality Monitoring Stations" (Air Date: March 2, 2004). Jennifer Quashnick from the Tahoe Regional Planning Agency discusses how researchers monitor daily weather and pollution patterns, not just for the Lake Tahoe basin but also the Sacramento and Bay Area regions, because of the impact of pollution on water clarity.

TranscriptionSegment 57 "Air Quality Monitoring Stations" Air Date: March 2, 2004 Anchor Intro: Researchers at Lake Tahoe have discovered that air quality actually plays a big role in the clarity of the water in Lake Tahoe. Shelly Purdy explains in tonight's Lake Tahoe Report. ((Take Pkg)) (( Track 1)) On a day like this, it's impossible to see anything in the air…except of course, the rain. Nevertheless, researchers monitor the air quality around Lake Tahoe throughout the day, every day. They measure the actual air quality and weather conditions. ((sot @ 7:51 Jennifer Quashnick, Tahoe Regional Planning Agency)) "The weather has a huge impact on how air quality is effected by sources. One example is in the wintertime, carbon monoxide form cars builds up because we have these inversions that trap, things on the surface and that's why we see our highest carbon monoxide in the wintertime." ((track 2)) That's why on clear blue days during the wintertime, there's often a brown haze blanketing the Tahoe Basin. It's the smoke and dust trapped in the air. In the summertime, additional pollution from ozone and particles from smoke and dust can often be seen as a regional haze throughout the Basin".…. [Note: Carbon Monoxide is colorless what you see mostly in winter is smoke and dust; in the summer- ozone and particulate matter are visible pollutants, just not as obvious to see because the inversions break up in the morning] ((sot @ 12:14)) "Ozone is generated when you have sunlight mixed with certain pollutants in the air. So as the sun comes up in the morning, ozone levels generally begin to increase. They'll peak mid-day then decrease as the sun goes down." ((Track 3)) But here in the Tahoe basin, ozone levels have been recorded to peak late at night. The cause… pollution floating in from Sacramento and the Bay Area. It's a concern regulators are taking very seriously as they make plans for the future. Because much of that pollution falls from the sky over Lake Tahoe and drops in the water…contributing to the clarity problem. Air quality not only impacts us in the air we breathe, it also effects the health of the lake and the forest. With the Lake Tahoe environmental Education Coalition, I'm Shelly Purdy for KOLO News channel 8. Anchor Tag: One way to do your part to reduce air pollution is to take fewer trips in your car, use public transportation, try to ride share or car pool to work, and finally, educate yourself about Tahoe's environmental issues and pay attention when it's time to head to the polls.
