	Studies that I have seen have shown that it isn't the rain-
water that is the problem. It is the clouds carrying all the water.
For instance, in the Adirondacks they found that the concentration
of acid in the clouds was very high and that the trees at the tops of
the mountains(where acid rain damage is greatest) spend most of their
time in the clouds. 
	I would think that watering your plants would not do them any
harm. The greatest damage occurs on the leaves of conifers.
The acid rain leaches out some trace minerals making it impossible
for the tree to make food. Unless you plants send most of their lives
within a cloud of acid rain, I don't think you'll have to worry about
it.
	Besides, most houseplants come from the sub-tropical and trop-
ical regions where the soil is more acidic.
