This sort of investigation probably needs something more like a gas spectrometer or a mass spectrometer. I don’t think a run of the mill set of air quality sensors is going to tell anyone which toxic nastiness is in the air there.

If there are any Marijuana Testing Labs in Ohio, bring them a sample of water...

Almost all weed testing labs have these machines in them. SPECIFICALLY for toxic chemical (pesticide) contaminants testing. I'd bet any testing lab in Ohio would do this for free.
