Waste Line Contamination

["Scott B. Webb, RSO" <swebb@lamar.ColoState.EDU>]

Our Facilities department is planning to replace all of the sanitary 
sewer waste lines in a laboratory building where long lived radioactive 
wastes have been dicharged via the sinks over the past 20 y.

I have advised them that the radiation safety of workers needs to be 
addressed for the demolition phase due to possible contamination within 
the pipes and that they should plan on disposing of the plumbing as 
radioactive waste if necessary.

The unplanned, increased costs have prompted them to request a survey of 
the drain lines. Since we have never, routinely, surveyed inside 
waste lines, DOES ANYONE HAVE DOCUMENTATION OF INTERIOR PIPE 
CONTAMINATION DUE TO ROUTINE SEWER DISCHARGES? Please respond directly 
to me.  Thanks
