ICP water test and shipping times

[erky]

Would taking over 2 weeks from sending out an ICP test skew any results?

for some reason the prepaid label on ATI's is slightly slower than the pony express. Why cant these companies do ICP here in the states rather than sending everything to Germany?

I suspect the data changes little, but I don’t think we have much actual info.

The only way I could see things changing is if bacteria and other microorganisms are takin up trace elements, or if it becomes stagnant enough for hydrogen sulfide to form and precipitate trace metal sulfides.
