Carbon 14 levels were not significantly above background. 

Sample results are at the 95% confidence level. 

NOTE: As a comparison, surface waters usually have a nominal 1000 picocuries of tritium per liter. State of Arizona drinking water regulations (see enclosed xerox) allow about 20,000 picocuries of tritium per liter.”

       Eight months following this correspondence, on June 11, 1980, the Arizona Game and Fish Dept. Director’s Office sent a letter to Ralph Ochoa of the AAEC. (84) The correspondence follows here in its entirety: 

“On July 30, 1979 I delivered ten samples of wildlife specimens to your lab for analysis. Your report to me dated 10/10/79 indicated your findings from sample #1 and #7. 

It was my understanding that analysis of the remaining samples would be delayed pending completion of your department’s investigations involving tritium contamination in Tucson. 

As discussed with you by telephone, we are particularly interested in analysis results of tag numbers 4, 5 and 6, the red-tailed hawks. As top carnivores, hawks have been shown to concentrate pollutants in various organs and adipose tissue. 

Please advise if you anticipate further delays pertaining to samples 2-6 and 8-10”.(84) 

       The Office of the Director, Arizona Game and Fish Dept. issued another request for test results on August 4, 1980. It reads as follows: 

“I am enclosing a copy of a letter from our wildlife manager at Oracle in reference to analysis of wildlife samples. Collection of these samples required considerable effort in addition to sacrifice of the protected wildlife. Please process and return your findings as soon as possible. 

Your assistance is appreciated.”(84)
