If APS plants are causing major pollution, then we will try to find a way to reduce
Our model’s purpose is to show how pollution spreads by the wind.
We began our project by learning about air pollution and major contributions.
Most of the pollutants that are contributed are man-made. There are some natural sources,
but not enough to cause any real change. The pollutants return to earth in the form of acid
rain and snow, damaging the ecosystem.
Fossil fuels are produced by automobiles, factories, or power plants. When fossil
fuels are burned, they put carbon dioxide, carbon monoxide, nitrogen oxides, and sulfur
dioxide into the air. APS smoke stacks produce many of these chemicals. They operate
eight power stations with a total of thirty-nine generating units in New Mexico and
Arizona; there are one to eight units per site.
Since more than 575 employees work at the Four Corners Power Plant, we
were curious about what effects pollution could have on humans. We found it can cause
breathing problems and cancer if you are exposed to great amounts for a long period of
The most current Toxic Release Inventory report we could find was for 1998. It
shows 1,050,000 lbs of Hydrofluoric Acid and 1,700,000 lbs of Hydrochloric Acid were
produced that year. Both are on the top five most potent chemicals produced by APS.
