PEKSACOLA, FLORIDA — U. S. NAVAL AIR TRAINUG COMMAND 



A19.OI Location of the Test Station and Test Boards 



Two test "boards of the panel type were Installed July 22, 19^^* 

 at different locations at the former U. S. Naval Air Station, nov the 

 Naral Air Training Cammand at Pensacola, Florida. The first of these 

 "boards, designated "by the symbol USHPF-1, vas Installed at the Ferry 

 Slip at the Naval Air Station. The second, designated hy the symbol 

 TJSKPF-2, vas located at the Feiry Slip at the Palafox Street Pier in 

 the city of Pensacola, Both of these test "boards are in Pensacola Bay. 

 It was later decided that a new test board designated by the symbol 

 USHPF-3, located at the Navy Railroad Trestle over Bayou Grande north 

 of the Naval Air Station, •^^ere this stream en^ties into Pensacola Bay, 

 would serve the purposes of the marine borer research better, so far as 

 this Station is concerned, than the test board located at Pensacola. 

 The new board was Installed on August 22, 19kh. The operation of these 

 test boards is beiiig continued, and resvilts of the tests have been sum- 

 marized to tbe end of 19^7« ' 



AI9.O2 Hydrographlc Data 



1. USNPF-1 (Ferry Slip at Naval Air Station ). The depth of 

 water where this test board was Installed was 20 ft; the tidal range 

 was 1.4 ftj the velocity of the current was not determined. _ The tem- 

 perature of the water at the time of installation was 80° F. The pres-, 

 ence of coliform bacteria was demonstrated in Domlnick-Lauter and lactose 

 broth media almost every month from the steurt of the test to the end of 

 1947. Estimated counts, beginning with April 19^5* showed the most prob- 

 able nuniber of bacteria of the coli-aerogenes group to range from k60 to 

 2lt-0,000 per 100 cc. 



2. U5NPF-2 (Ferry Slip at Pensacola ). The data for this test 

 board are the same as for the preceding one, except that the most prob- 

 able nuniber of bacteria of the coli-aerogenes group ranged from 6OO to 

 700,000 per 100 cc. 



3. USNPF'^3 (Railroad Trestle at Naval Air Station ). The depth 

 of water where this test "board, was Installed was 13 ft. The teiiQ>erature 

 of" the water at the time of Instnllatlon was 84° F. The other data 



for this test board are the same as for the first one, except that the 

 most probable number of bacteria of the coli-aerogenes group ranged 

 from 450 to 700,000 per 100 cc.
