In general you are correct but have you heard of acid rain. I think that it depends on what is happening.

SD is right on this one.

The distillation occurs as the water evaporates into the atmosphere.

For the water to fall usually requires some particle of dust or such for the vapor to condense around. This can be a speck of sulfur dioxide, plain old dust, or dust contaminated with radiation, disease or poison.

In that situation the water falls as a contaminated substance.

Those of us that were children in the '50s and '60s were warned off eating the snow by our various defense departments due to atmospheric nuclear testing of that time.

Here in the states, back in the 1980s, we went on a campaign against acid rain due to the depletion and death of large tracks of forest in our eastern mountains. After years of expense, loss of industrial output, change of economic focus and life style, it was discovered that the killer of the forest was the southern pine beetle, not the acid rain.
