Dear list,
I would like to receive some advices about setting alert and action levels
for environmental monitoring program in an injectable department.

Which statistical approach do you apply (normal distribution, negative
exponential distribution, ...) ? Do you set different levels for each
location (very difficult to manage, I guess) or you consider all the data
from the same grade locations ? Are you required to set statistically levels
for all classes (for grade A and probably B it does not sound very
meaningful ...) ?
