October 25, 1952 To Clifford Beck From N Underwood Subject.- Sewer monitoring

Four inch cast iron drain pipes provide access to the entrance, the tank, and the exit of the tank. The decision as to how these access pipes are to be used is yet to be made. Dr. Waltner and Mr. Turvey have found that coating a stainless steel counter with 3 coats of strip paint and one coat of silicone stop cock grease makes it possible to remove the surface contamination acquired by immersion in a radio-active phosphorous 32 solution for periods as long as 2 weeks. How successful this coating technique will be against more complex chemical and radio-active contaminants is not known. To what extent the background will build up in the sewer pipes themselves is not known. In view of these uncertainties, it may be advisable to plan for a system of pumping samples up to the surface of the ground and into special catch basins for monitoring the sewer.

The equipment for these monitoring systems has not been ordered. The specifications for this equipment can be properly set out only after numerical information is available as to the amount and kind of activities that are to be measured.
