Toxic

The EPA sent out flyers offering testing and cleaning of the flats
around ground zero.  The EPA website lists TONS of info about the toxic
elements we've been exposed to.  There is also recommendations for
clean-up.  The EPA recommends continual cleaning.  For months following
9/11, I had to clean every couple of days because of the settling
residue.  I now find I only have to clean every week.  I use a special
HEPA vacuum and the "wet dust" method.  I run the air filters when I
clean.
