It depends upon the types of pollutants, but a common result is acid rain.
sulfur dioxide
... produced by sunlight.
When it rains, the rainwater mixes with trash and other pollutants and it is carried down our storm drains and into our oceans. Gasoline and sewage spills from boats and ships also contribute to the pollution problems. Also if people do not clean up there trash and just leave it into our community then when it rains, the rain picks up all the trash and then goes into sewer drains, and the sewer drains lead to the ocean.
The teo most common pollutants that mix with water in the air are sulfur oxides (SOx) and nitrogen oxides (NOx) These pollutants create acids with water. The combination is known as Acid Rain or Acid Precipitation.
There are two types or rainwater haversting. Rooftop rainwater harvesting and drain harvesting. In rooftop rainwater harvesting, we use the water collected on rooftops instead of letting it go down the drain. We can also use water collected in dugout ponds, underground vessels etc. Drain harvesting involves letting water collected in roadside drains go straight to the ground. But this water has to be treated before use as it may contain bird faeces, germs and other pollutants.

The pH of the rainwater will go updown,updown!
sulfur dioxide
Rain water is usually fairly clean, but it can contain pollutants from the air.
Stratospheric ozone is pollutant. It is because it mixes with other pollutants.
salt salt makes it more acidic
When the rainwater reaches the surface, it comes in contact with the atmospheric dust particle. This dust particle mixes with the rain water, making its character bit contaminated. In this way the rainwater looses its color also.
Precipitation can carry pollutants in water whereby when moisture rises and mixes with gases from industries thereby condensing and falling back as acid rain may carry the pollutants into water.
Rainwater is normally acidic because the carbon dioxide in the air which mixes with rainwater to form weak acid. That's why its acidic ^_^ Rainwater is also because of the pollutions in the air and it mixes with the water so its not good. meee!
CFC's are the pollutants. They react with ozone to deplete it.
