Excellent example of badly used statistics.

Here, on page 2, a study on infrasound conducted by Mr. Richard James is referenced. Mr. Richard James references Nina Pierpont's "Wind Turbine Syndrome" in articles he has written, namely "Wind Turbine Infra and Low-Frequency Sound: Warning Signs That Were Not Heard," see this link. Wind turbine syndrome is not a real medical syndrome, see this link and this link. In fact, Mr. Richard James and his methodologies for measuring sound has been discredited in a Michigan court, see Rick James – A Technical Discussion of His Deposition and Testimony in the Spencer / Kobetz Lawsuit.

On page 7, we learn that Mr. Richard James trained a field technician to set up sound measuring equipment at a dozen homes within the Shirley Wind Farm. It's unclear if Mr. Richard James was present to ensure set up and staging of equipment was per professional protocol. The trained field technician is stated to live within the Shirley Wind Farm. Mr. Richard James also collected weather data using a website called wonderground.com [sic]. Note that the field technician didn't record weather data via actual observation while domiciled within the Shirley Wind Farm. Also to consider is the likelihood of gaps in the collection of data, "On many occasions, there was an observer recording the events of the turbines..." This sounds fuzzy. Brings doubt to the reliability of collected data.

On page 13, the Brown County Board of health declares the Shirley Wind Farm a human health hazard.

As a result of Brown County's declaration, the Governor of Wisconsin will spend $250,000 to study health effects of wind power.

In what concentrations? "Toxic" is pretty meaningless.
