Monday’s newly formatted Chicago Tribune had a feature story on air pollution.

There wasn’t anything I could find in the paper about McHenry County except this map.

But, there were air pollution sources that could be found for each Illinois county.

McHenry County doesn’t have any really, really big air polluters. The top three, ranking nationally at 1,218, 1,303 and 1,740 were Marengo’s Arnold Magnetic Technologies, Woodstock’s Arntzen and Marengo’s Danaheer Motion.

Arnold Engineering I’ve heard of and I assume the company with the Arnold name is a successor. I am not aware of the other two.

The McHenry County list drops down to 3,625 with Ringwood’s Rahm & Haas Chemicals at 4th.

Another big leap has to be taken to find air polluter 5 in the county. It’s identified as Knaack Manufacturing in Crystal Lake at 6,088.

Back to Marengo for number 6 coming in at 6,357: Engineered Polymer Solutions.

Number 7 at 6,904 is in Ringwood: Huntsman Polyurethanes .

Algonquin’s Wauconda Tool & Engineering Company is 8th at 7,416.

9th place–8,382–went to Bartlett Manufacturing of Cary.

At number 10 was Techalloy of Union. It ranked nationally at 8,787.

Companies coming in lower on the list are the following:

10 – 8,787 in Union: Techalloy.
11 – 8,858 in Spring Grove: Intermatic, which is moving overseas.
12 – 9,263 in Richmond: Claud S Gordon Company.
13 – 9,812 in Crystal Lake: G & M Manufacturing Group.
14 – 10,186 in Cary: Fox Valley Systems.
