North Monitor

Shown below is simulated  web output from the North Laser Air Particulate Pollution Monitor soon to be located right next to the plant site.

Each reading from a Dylos DC1100 instrument is averaged over five minutes and the graphs are updated every thirty minutes. Large particles (above 2.5 μm) are shown in red while small particles (down to 0.5 μm) are shown in orange. Wind conditions and humidity are collected simultaneously from the weather station at the coordinates 44-52°N 091-29°W. The north (green) and west (blue) wind components are recorded separately and are calculated to provide a true vector average. (For details, see the second method cited at

Originally, it was proposed that there were to be multiple monitors around the plant site so that by subtracting the incoming air pollution number from the total pollution leaving the site, one could calculate the amount of pollution produced by the plant regardless of the direction of the wind. Since the plant operators have resisted this idea, we are installing a series of private monitors, situated as near as possible to the proposed site. These privately owned monitors are now measuring and recording the total particulate output of the air passing over the proposed sand plant plus all other airborne particulate producing sources upwind, including farming, construction, diesel exhaust, road dust, and surprisingly, water vapor. Over time, we can produce a baseline reading before any Sand Plant operations start, so we will be able to measure the increase in particulate pollution due to Sand Plant operations. As you can see by watching the particulate count each day, our air quality is not good. We don’t need more dust in the air.

Based on readings of a similar monitor in Menomonie, near the sand plant there, we expect to see our pollution index increase by orders of magnitude when this Plant actually goes into operation inside the city limits of Chippewa Falls.

Long rants proclaiming the infallibility of your own views or favorite ideology will not be posted, neither will repeated attempts to hammer on a point already addressed, nor will comments containing profanity, abusive language, flame-baiting and name calling.

I have no idea what they were referring to and no way to contact them.
