   A car drives through dirt and debris while rain just comes out of ocean   
   (which is what's happening now with these atmospheric rivers).   
      
   And snow is pure white where I live, at least until people walk near it.   
      
   I can see the FIRST rain being dirty like the roads get slick from oil,   
   but after weeks of almost daily rain, I wonder how much acid is left.   
      
   Didn't the EPA get rid of "acid rain" long ago in the US already?   
      
   For me, there isn't an industrial city anywhere and if there were, I guess   
   only a portion (How much? I don't know) of the acid is washed out in each   
   rain. And, only a portion of the acid is ADDED to the atmosphere each day.   
      
   Of course, then the ratio matters, for example, if we have ten rains, and   
   10% is washed out in each rain, the next rain is clean; however, if 5% more   
   is added between each rain, then it would take 20 rains to wash it all out,   
   and even then, 5% would be added the very next dry day.   
      
   So if you had two dry days in a row, it would take another rain to wash it   
   out. But didn't the EPA fix all that long ago?   
      
   If you ever run into a statistic on how acid the rain in the rural areas of   
   the US alongside the ocean is, that would be interesting information.
