Fresh Water Furnished for Decontamination and Transient Vessels (in gallons). site was brought within the productive capacity of the plant. Close surveillance of the use of fresh water from midnight to 0400 hours over a period of years has provided an indicator of leakages in the system. During the heavy construction period on Elmer, in the early months of 1958, the frequency of breaks in the transite pipe of the distribution system was relatively high, but through a coordinated system of testing and repairs losses were kept at a minimum. Complete operating, production, and consumption records were maintained and reported monthly to the AEC which indicated that the demands for fresh water are increasing with each Operation. As an example, per capita daily consumption of fresh water during the opera- tional months of REDWING was 54 gallons at Elmer and 47 at Fred as compared to 58 for Elmer and 58 for Fred for HARDTACK. The increasing consumption was partially due to greater operational requirements for washing down planes and other equipment and for decontamination. More and more calls for fresh water were received from transient ships visiting EPG, with issues limited to quantities necessary to make the next port-of-call. An unusual requirement was that of ionized water for use in the missiles of the TEAK and ORANGEevents. Specifications for water were established by the User group at a maximum impurity content as follows: 6 ppm Sodium Chloride (NaCl), 6 ppm Calcium Carbonate (CaCO,), and a minimum specific resistance of Page 434 35,500 ohms/cc. A total of 2800 gallons of water conforming to these specifications was required to be delivered in two lots of 1300 gallons each in appropriate tank or container with pump and metering device located on a mobile unit and 100 galions each in 5-gallon glass or plastic con- tainers. On 2 April 1958 arrangements were made to supply the water meeting the specifications. To meet the requirements, distillate produced from Cleaver-Brooks S-2100-D Unit was redistilled through the use of a Cleaver-Brooks $-600-D Unit. Redistilled condensate tested the following: 3.0 ppm NaCl, 0.5 ppm CaCoO,, and a specific resistance of 68,000 ohms/cc. Redistilled condensate of the above impurity content met the requirements as specified. Original planning provided for the making of the water at distillation facilities at Elmer and its transport to How when required; however, the relocation of the ABMA facilities necessitated the shipment of distillation equipment, together with auxiliaries required for unit operation, to Johnston Island, where the facility was activated on 17 July 1958. Through the use of four stainless steel tanks, three S-600-D Distillation Units, and appropriate piping arrangements, 3000 gallons of redistilled condensate were produced to specifications. The final readings of samples taken prior to deliveries for the TEAK and ORANGE events were 840,000 ohms specific resistance at 84° F, 0.0 ppm CaCO., and 0.0 ppm NaCl.
