     I can't answer your question on why the vapor tests are so low, but I
can tell you a crooked strategy at Fort Ord to get their numbers down on
toxic testing and here's an example.  The beach firing ranges, first they
raised the allowable contaminant level for lead to 1860 ppb, up from 400.
Then when they couldn't get the numbers to fit their cleanup they calculated
in the parking lot and walkways.  Bingo! they got it down, at least on
     When the state went to receive it so they could make it a state park
their tests deemed it too toxic, so it sits alone after killing all those
National Marine Sanctuary animals for nothing, not to mention wasting tax
payer dollars and the health injuries to those driving by on the freeway or
living next to the pile on base they hauled it to where they sifted it for
the lead and copper.  The sifted metal for sold for $7,000,000.
