i have a water filter business.
and have recently pushed an ad
campaign aimed at fellow fire
victims...as streams and wells
have been contaminated with ash
and fire retardant and other stuff.

i have been drinking water from the
stream for many years and used these
solid carbon block filters to remove
impurities, giardia cysts, and etc.

i have seen wter bottled in bio-degradable
bottles (made formcorn starch or such) but
wonder wha their shelf life is....
