Please see the note below from Critical Systems and Nebraska Nova about the building's RO System. This may affect the distilled water lines in the labs, but we will be alerted if water runs low during the cleaning process. Maybe have some back-up water on hand. Thanks, Jayne Stratton

Hello Jayne, We are going to clean the RO system only tomorrow starting at 10am. You should have water in the labs as it should only take a few hours to do this. I will update you if we start running low on water.

Then we will take some water samples in the labs to analyze for a bacterial growth being present. This will decide if we set up a system wide cleaning.
