This email is to let you know that we had a brief interruption in water pressure for the BNC Ultra Pure Water (UPW) this evening. A faulty pump may have caused those of you conducting experiments to notice a lack of UPW pressure Saturday between 9:50 - 10:30 PM. The system is back up and running at this time. Please be aware that the water may contain slightly elevated levels of Total Organic Carbon (TOC) for the next 12-18 hours while the system stabilizes. Thank you for your patience and let us know if you have any research problems due to this interruption. -- BNC Staff ------------------------------------------------------------------------
