Uranium and Phosphate in the Eastern Part of the Bonny Lake Mine, Polk County, Florida
From abstract: This report comprises data derived from 53 prospect drill holes drilled by the Davison Chemical Corp. in the eastern part of the Bonny Lake mine, Polk County, Fla.
Uranium and Phosphate in the Western Part of the Bonny Lake Mine, Polk County, Florida
From abstract: During the month of May 1950, the Davison Chemical Corporation, under contract with the Atomic Energy Commission, drilled 24 phosphate prospecting holes in the western part of the Bonny Lake mine, in the SW NW4 and the NW*SW4 sec. 32, T. 29 S., R. 24 E., Polk County, Fla. The purpose of this drilling was to obtain a comparison between tonnage and grade of uranium in the phosphate as indicated by prospecting, and the tonnage and grade of uranium in the phosphate products recovered in the mill. The results presented in this paper are based upon a study of drill cores, drill logs, gamma-ray logs, and the chemical analyses of drill-core samples.

Results of Deep-Well Injection Testing at Mulberry, Florida
From abstract: At the Kaiser Aluminum and Chemical Corporation plant, Mulberry, Florida, high-chloride, acidic liquid wastes are injected into a dolomite section at depths below about 4,000 feet below land surface. Sonar caliper logs made in April 1976 revealed a solution chamber that is about 100 feet in height and has a maximum diameter of 23 feet in the injection zone.
