    Pure water picks up all manner of chemicals from the air it falls through. If there is an excess of carbon, sulfur, or toxic chemicals, they can get dissolved or carried by the water to the ground.

    That’s where acid rain came from.

        Coincidentally, that process is how industrial gas scrubbers work. Imagine a showerhead inside a tank with a ton of macaroni pieces. The dirty air comes from the lower side and and a solvent (water works in many cases) pours through the shower. The contaminants dissolve in the water and air is purified (to an extent). That high surface area works wonders to exchange molecules.
