Air quality in Evansville is atrocious but of course the official monitors are not working

November 16, 2012-by John Blair editor

Below is a picture I shot this morning of the atrocious air pollution in Evansville today, 11/16. It was basically the same yesterday as fine particles built up in the region. Unfortunately, IDEM nor  the local EPA has any data to record what is probably an exceedance of the 24 hour fine particle standard so there is no air pollution alerts or anything to warn people of the severity of the problem.

This is what the air looked like this morning in Evansville along Riverside Drive, as fine particle pollution rose to unhealthy levels. Unfortunately, we will not know just how unhealthy since once again the official monitor for the city was “down for preventative maintenance” for this air pollution event, which started yesterday. Valley Watch has completely lost trust in both IDEM and the local EPA to provide honest assessments of air quality since it seems the monitors never work correctly when the air quality is bad.

IDEM is supposed to maintain a near real-time data website ( but for the last two days, while air quality worsened, their site shows absolutely no data using the term PMA instead of quantitative figures. IDEM defines PMA as: “PMA – Preventative maintenance. Indicates the CAMS is undergoing maintenance and data collected is not valid data.”

Sadly, what is happening today and yesterday will likely not be included in any determination of whether or not we actually meet the health based standards for fine particles  since the monitor is conveniently down for “preventative” maintenance. Maybe by “preventative” they mean prevent a violation of the standard.

I am asking for permission to publish a letter a Valley Watch board member received from Evansville EPA leader, Dona Bergman and will share that when permission is received but in the meantime here are two sentences from that letter, date August 1, 2012 which was in response to data that USEPA had collected which showed EVV air quality was worse than the State and local governments were acknowledging, “For much of the period you examined, the data from the BV continuous monitor had a high bias (see for example the chart below).  In fact, quite a bit of the Buena Vista monitor’s data were removed from IDEM’s websites because they were invalidated.”

It seems that every time there is an air quality problem around here there is some kind of excuse forthcoming as to why the official monitors are incorrect except on days when air quality is on the good side, then they are never wrong.

    Moving from Henderson, KY to Newburgh, IN seven years ago was a drastic mistake. The pollution from Alcoa, etc . has become unbearable. Where is the outcry?

    John, has anyone in your circle looked into the phenomenon of geoengineering? The air pollution (already bad enough in the Ohio River Valley) which has increased over the past 3-4 years substantially is due to geoengineering. The atmosphere is being blanketed with heavy metals which refract solar rays. They are primarily aluminum nano particulate matter. Check out to learn more details. This is so far beyond a few corporations. Its time the American public wake up to this. There are 17 million hits on the webpage. It will not be long before enough people realize what is being done to them. The powers that be will not be able to hide this much longer in all probability. Then the propaganda spin machine will really fire up. If you’d like to discuss in more detail please feel free to email me. Thanks.

      I understand your concern. Please contact me and we can discuss further offline. All you have to do is look up. Again, Wigginton’s website – geoengineering watch – is the best I have ever seen. You already understand the true nature of the men who sit in position’s of power and the general disregard they have for human life. Our technology has outstripped our morality. Again, please email or call me. I have a lot to share with you. Looking forward to hearing from you. Sincerely, David

  3. I’d be interested to know how the levels of pollution here in Evansville have changed in the years since this article was written, and whether monitors are more effective now. It’s so important for all our health that we control these levels.

    Fantastic items from you, man. I have take into account your
    stuff prior to and you are simply too magnificent. I really like what you have acquired here, certainly like what you
    are saying and the best way wherein you say it.
    You’re making it entertaining and you still take care of to keep it sensible.
    I cant wait to learn far more from you. This is
    actually a great website.

    Our air quality here in Monroe, LA is rated at Ozone 40 which says it’s “Good” and
    Particles (PM2.5) at 53 which is “Moderate”. I wonder how that compares to your air quality there in Evansville?

    Hey John, this has been going on for years…where the air quality monitors sometimes conveniently don’t work? What do you see as the main reasons people don’t seem to care about the air quality in their own back yard? Where we in Vand Co now have the distinction of being in the top 10 counties in the US for worst air pollution.
    Thx for all you do and have done over the decades.
