 Analysis of Samples from the 900 Meter Pacific Dumpsite," 

 September 1979. 



This report presents raw data, without interpretation, of 

 radioanalysis of sediment and biological samples. It has undergone only 

 preliminary EPA review at present. 



The conclusions which we have drawn from the report are that the 

 radiation measured in the biota is in the range expected from fallout and 

 that the concentrations present do not represent a source of harm to 

 either man or the marine environment. Concentrations of radioactivity in 

 fish collected in the vicinity of the Farallon Islands are within the 

 ranges occurring from atmospheric fallout. Human consumption of such 

 fish would yield an annual estimated dose that is approximately 1,000 

 times lower than the dose from radioactive materials occurring normally 

 within the human body.

 Collected from the United States Radioactive Waste Disposal 

 Site Off the Farallon Islands, California," August 1978. 



The contractor taxonomically identifies infaunal and benthic 

 organisms collected at the site. He reports no unusual findings in terms 

 of biomass or species present. No aberrant forms were found. 



EPA is attempting to characterize the biological populations in the 

 site area. We are interested in studying the role of benthic and 

 infaunal organisms in terms of the potential for bioturbation (reworking 

 of sediments which might enhance mobilization of radionuclides), and for 

 biological uptake for potential transport through marine food chains.

 Site Survey; Phase I - 25 August to 2 September 1977. 



Or. Robison 's report summarizes the operations of the 1977 site 

 survey and also provides useful suggestions for future survey work. 



(8) Robison, Bruce H., "Midwater Trawling Summary: Farallon 

 Islands Disposal Site Survey, 1977." 



Midwater organisms, many of which may be highly migratory, could 

 provide a go-between food chain transfer mechanism between deep ocean and 

 near-surface waters. This report identifies and describes the mid-water 

 populations found at the Farallons site. As in Reish's report (06), 

 there were no unusual findings in terms of biomass or species present, 

 and no aberrant forms. The sample size was insufficient to provide an 

 understanding of actual food chain pathways between bottom and mid-water 

 regions.
