Description
A letter of correspondence from John R. Thoman, the Regional Director of the Water Supply and Pollution Control Division of the U.S. Department of Health, Education, and Welfare, to A. D. Aldrich, the Director of the Florida Game and Freshwater Fish Commission. The letter discusses the analysis of the samples taken by Eugene W. Surber during his visit to Lake Apopka, Florida, in June 1963. Analysis of fish samples performed by chemists with the Department of Health found large concentrations of dichlorodiphenyltrichloroethane (DDT) were in the bass fish samples. According to the letter, Thoman does not believe these concentrations necessarily indicate DDT poisoning as the cause of death.
