Dear compulsive ABRF'ers,

Our facilities will be moving to new quarters by Christmas and I am evaluating
how the move is going to impact the facility. Nothing scares me more than
moving and then finding for some unkown reason we can't get a signal out of
the noise.

I've tested the central (reverse osmosis) water and my current location has a
conductance of less than 1 microseimen, the new space is testing at 50
microseimens. Boston tap water tests at 150 microseimens.

So do I install an expensive set up to feed the stainless steel dishwashers
etc. or do I convince them they need to figure out what is wrong with the
central water supply.

Please send me all of your anecdotal stories that explain how water quality
impacted on data. The more horrific the better. Before and after numbers
detailing the quality would also be good. Any molecular biology process will
do but if it's fluorescent DNA sequencing, HPLC, acrylamide gel, mass analysis
or protein sequencing that was impacted so much the better. Should I be
testing for something else besides conductance?

If I live through it I'll post a follow-up on how to survive moving your
facility.

thanks, Paul
