I am working on a large (9000+ burial project which involves skeletal and partially decomposed remains from 1950's-80's. Currently I am utilizing masks and gloves. Today the manager for the project requested that I substanciate through documentation my reasons for the precautions. They feel that the risk is so negligible that such precautions are not warrented. Some of these burials have cause of death listed as TB and a few were listed as diptheria. Histo and blasto are high in this region (in the soil) according to the state epidemiologist......but he couldnt offer advice other than "I wouldn't exhume burials without those basic precautions"......he also said that what would worry him is anthrax.....but still that doesnt help my situation. So if anyone out there can help, I would be greatly appreciative. I have information on Spitalfields (ie lead and smallpox) and I have the CRM (feds)issue on arsenic contamination. I do not have anything on chemicals used for this time period. SK Parker
