Controlling dust near highways doesn’t come cheap. And Arizona’s spent almost $600,000 dollars of your money to suppress blowing dust this monsoon year. Most of the problem dust is coming from a wealthy farmer’s land. Tom Hermann with ADOT says his agency’s portion of the bill comes to

$307,000 thousand dollars, including $112,000 in contractor costs, with the rest going into ADOT personnel and related expenses.

Hermann says A-D-E-Q is working with the farmer on a consent decree. This year, the State’s been applying a dust suppressant called “Gorilla snot” in the hard hit area of Interstate 10 between Casa Grande and Tucson.

Hermann says there has not been any dust-related closures along interstate ten since May.
