Probably the hit movie "Brockovich" or something like that. It's about a
chemical company making a neighborhood sick by dumping large amounts of
hazardous chromium wastes into the water supply. (I didn't see the movie,
just read about it.) Thing like that seems to linger in the subconcious
just by hearing about it.
Note that for those people using large quantities of dichromates (like a
commercial printer or platemaking outfit in photography) the hazards are
real. Dumping wash water containing trace amounts shouldn't be a problem.
OTOH, disposing of leftover chemicals in quantity is best done by
depositing the stuff at a registered hazardous materials disposal site (I
don't know about where you live, but in the tiny county in Florida where I
live, there are two such places run by the county).
