Mail of a 40 20 40 15 Lines 22 27 277 0 In Use Trunks 20 15 7 7 10 34 15 routine nature, such as confirming data, correspondence containing information and instruc- tions in which time was not considered essential, plans, drawings, and other documents, was handled through this medium. The handling of this mail was in accordance with AEC in- structions and Security Regulations and was accomplished through a classified mail messenger service. At the start of this service, mili- tary couriers were used, but this service was later performed by Contractor employees. The mail pouch was manifested, the pouch sealed and then placed in custody of the courier for transit between atolls. At destination the pouch was receipted for, and upon verification of the contents, a copy of the manifest was signed and returned to the originator. SECTION 8 SALT WATER SYSTEMS AND SEWAGEDISPOSALS Salt water requirements at all temporary camps were met through the use of shallow water wells. The camp needs of site Elmer were met through the use of a well in Building 301, while the CMRarea received its supply through a lagoon intake. An entirely new well and pump- — ing station was built at Fred to meet the re- quirements of that site, but due to pumpdiffi- culties this supply had to be augmented at times by the lagoon intakes through the old pumping station. Although some “sanding up” of the wells was experienced, on the whole they proved far more advantageous as a source of salt water than the open lagoon intakes. Marine growths and other foreign materials were effectively screened through well operation. On the other hand the marine growths and Page 4-52 foreign material, particularly paper trash from vessels in the harbor, entering wells through a lagoon intake excessively aggravated the operational work load of the CMR powerplant. At all pumping stations, except the CMR area, both motor driven and gas engine driven pumps were provided to insure reliability of the salt water supply. Tower tanks were installed which rode the distribution system, thereby providing the necessary head. The pipe networks were generally constructed of asbestos cement pipe of various sizes. Except for a few breaks in the piping system (the normal incidence of accidental breakage), there were no particular problems in the salt water distribution systems.
