I also thought that test was expensive.  I checked with some  
colleagues and found one firm that told me "Yes, we can do the testing  
for Legionella and Acanthamoeba.  Depending on the methods used, the  
pricing would be between $200 and $300, all-inclusive (i.e. both tests  
on each station).  There are other options to bring costs down such as  
collecting composite samples, etc."

But, as numerous posters already pointed out, there are other  
compelling reasons to test/flush weekly (sediment, damage, water  
supply integrity) regardless.  And weekly testing goes a long way  
towards reinforcing the location and operation of the safety  
equipment, an intangible benefit that should not be overlooked.   
Recall the recent list posting about the worker who apparently ran  
away from the safety shower location after catching fire, for example.
