Four water sensors have been installed on top of the T1 monolith.  These water sensors were wired and brought to the area during the 2014 shutdown, but installation was delayed so that the top of the monolith could be painted first.  The sensor labels (attached to the sensor cable) are: T1, T2, T6, and T8.  The location of each sensor is documented on the diagram below.  Two photos of the top of the monolith are also attached.  Doug Preddy has been notified.
