I've been lurking here for a while, but since I'm a scientist and not an aircraft researcher, never dreamed I would be posting.
My scientific background is relevant to this report, though, so here goes. This report is fascinating and thorough, and the conclusions are well thought-out.
I do see a couple of minor discrepancies having to do with the units reported on some of the analyses. These do not appear to affect any of the conclusions of the report, however, but I note them for clarity and also because I find it important to have correct units, because later researchers will often refer back to earlier reports and will rely on the units as reported.
The apparent discrepancies are:
Under "What did 2-9-S-1 contain?" this statement:
"The test results showed mercury in the interior at a level of 4 micrograms (µg) per 50 milliliters (ml) of solute."
The analytical reports by EAG show that the concentration in the liquid was 4 micrograms per liter. (The Coke bottle report by EAG shows it as 0.004 mg/L, which is the same as 4 ug/L.)
It appears, therefore, that there were 50 mL of leachate containing 4 ug/L of mercury, rather than 50 mL containing 4 ug of mercury. (4 ug in 50 mL would be 80 ug/L.)
The assumption that there were 50 mL containing 4 ug/L of mercury was used in the spreadsheet where this concentration was converted to a mass per surface area figure for comparison with background surfaces. On that spreadsheet, it appears that the units in cell A1 are ug/L, and in cell H1 should be ug Hg per cm2, not ug per liter per cm2. (The liters canceled out.)
Again, I think the numbers are correct, but if I'm following this then the units just need to be tweaked.
I'm now going to be away from computers for the next week. If I'm wrong here, please excuse me!
