CHAPTER V, SECTIONS 4 and 5 where it could be skimmed off. After several months of operation the organic substance disappeared from this well. at Elmer was renewed because corrosion had so thinned the metal plates that structural failure All metal piping and fittings suffered from the corrosive acticn of salt water and from loss of aperture and plugging due to salt deposits and metallic oxide. The salt water header in the distillation plant at site Elmer had to ve completely renewed. All the pump casings in the CMR system required Jitting and repairs as corrosion took place in the threaded joints and the casings separated. The salt water tank SEWER SYSTEMS. Maintenance of sewer systems was primarily concerned with preventing the clogging vf service hnes and tnains. Heavy paper towels and other trash were thrown was considered probable. in toilets, wasn basins and urinals: excessive oxidizing of metal lines also took place. Because of the flat terrain of the various camp sites and fhe consequent low gradients of the sewage collection systems, periodic flushing was required. SECTION 5 AIRSTRIPS AND ROADS AIRFIELDS. As the airftelds on sites Elmer and Fred at Eniwetok Atoll were completely reconditioned, and the one on Peter-Oboe at Bikini was newly constructed for the CASTLE test proxram, maintenance byitself was limited in scope. Primarily, this consisted of small patchwork, patrolling, watering and rolling only as aircraft operations warranted. The intense use of the Fred airstrip during OPERATION CASTLE did result in dislodgement of the dust palliative stabilized areas, and future ictreatment will be necessary. ROADS. All roads, except those on Fred, were satisfactonly constructed and maintained without bitumul finish. The patrol grader was usedl on schedule, and also after heavy storms, to maintain the surface. A water truck was used to allay the dust during prolonged rainiess periods. The bitumul-treated roads on Fred, though frequentiy used by tractored vchicies and other Some The roads on all islands at Bikini were, on the whole, satisfactory and maintenance consisted of the oecasional use of the moter patrol. The road between Fox and George became inundated during a few verv high tides or storms and after the water drained otf it was necessary to remove the accumulatec debris (Figure 5-1). The causeways, built of earth and rock-fill, suffered heavily from storms and high tides: crosion Was excessive during these periods. When this ocurred it was necessary to haul replacement fill and then re-blade. An aggravated erosion condition which appeared to threaten the Operation on the Rubv-Sally causewav was alleviated by constructing on the ocean side of the causeway a bulkhead of steel rails and twoinch boards, which was then back filled. Generally a stockpile of fine aggregate was tiatuiaimedt om Various sites «which wes used, as necessary, to maintain roads and stabilized areas. ewe ee heavy equipment, stood up very well. patching was required A power broom was used for sweeping when necessary.
