Septic Tank Sludge Information

[Arthur Shanks <ASHANK@envc.sandia.gov>]

We are attempting to gather information regarding the environmental
background levels that would be found in normal septic tank sludge.  We
are primarily interested in background due to NORM; however,
information regarding other background radionuclides would also be
helpful.  Can anyone give me information on any published results from
such a study, or does anyone have results that were gathered from their
facility.  Would prefer data from septic tanks rather than municipal sewer
systems but both might be helpful.
