thanks for the terrific post.
Local TV News - horrible place to get informed. They aren't interested
in the steak, only the sizzle. They are only worried about you
exercising remote control options which is why they spend more time on
'bumps' than delivering news (Bumps are apparently the term for the
teases they put in about upcoming stories - most stations run
approximately 20 in the 30 minute news broadcast, deducting for
commercials, weather, sports and bumps leaves very little time for
actual news). Now that they have trained us to have a 3 minute attention
span, they assume that we only have a 3 minute attention span and
details have to be gotten elsewhere. Local news is the place to go to
get the scariest side of local events without substance or redemption.
Putting a Ben Stein type on air explaining these details would cause
people to scramble for their clickers.
Clean dirt - 2 ppb, arsenic 7 ppb, many many other substances at varying
levels of inclusion and Siri pointed out the significance of turbidity.
I can tell you that the $600 check I got from Baker et al v. Motorola
hardly paid for the bottled water I used over the years and I suppose
the 'sic' bright side is an underground plume of TCE coming soon to a
water well near you. Of course TCE is one of those things that they try
to keep in a low number of ppb when things are working well.
Me afraid of the water? Only when I think about it. ;-)
